This comment has no relation to the issue. This issue not about notification, but about issue access control

--------------------------------------------------------------------------------
While I've read the commentary about how watchers are the wrong mechanism for this, I needed this functionality to upgrade my company to v1.2.1 and meet our privacy needs. We'd previously been using the 'view own issues' patch in an old release which works roughly the same way.

Consequently, we cooked up this patch. It over-rides the @addable_watcher_users@ method from @acts_as_watchable@ to allow any user who can view issues to be added as a watcher, and then adds watchers of the issue to the @visible@ named scope and the @visible?@ method so that they can see operate on the issue.

I don't expect this patch to be accepted but if, like me, you can't wait another 4 years for this to get straightened out then maybe this will help you.

I've only tested this in the context of my environment, so I can't promise it won't do terrible things to yours. I'm not Rails wizard, but I think it's pretty low impact. Your Mileage May Vary. If it breaks, you get to keep both parts.

Hello
After patching some problems happened :
Simple users cant access Activity page and give 500 Internal Error .
so i redo patch changes and all things work true .
--------------------------------------------------------------------------------
I have updated the patch for allowing watchers to see private issues to fix an issue with the Activity page -- there was a reference to Issue.visible_conditions in the journal model (which is related to the Activity page) which requires an include of the :watchers relation.

This updated patch should fix the issue with Activity giving a 500 Error.
--------------------------------------------------------------------------------
Well done .
Thanks .

But now if the assignee is changed, the old assignee gets an 403 error if he is only allowed to see tickets as an assignee or ticket issuer.
Is there a way to redirect the user to the issues page after altering the ticket assignee?

--------------------------------------------------------------------------------
Is there a way to add the one updating the issue automatically as a watcher?

Hey Bruno,

i tested it on 1.3 and it seems to work like a charme :) Thank you very much. Only question i have, is it possible to send an email also out to the watcher, when he was added to the issue or the issue was updated?

Thank you very much for your work!! :)

I don't believe we can send email when adding the observer/watcher, but redmine is supposed to send an email when the issue is updated if the proper config is set on the administration options.

If I understand correctly, I have the same problem.
I use last patch: "private_issue_watchers_FIXED_1.3.diff":http://www.redmine.org/attachments/6892/private_issue_watchers_FIXED_1.3.diff, but simple users can't access to links like this @/projects/project_name/issues/report@.

How stable is this? What is the process to get this steamed into the main Redmine branch?

I guess we could pull this out into a plugin, but it would be nicer to have Redmine support this idea natively.

As explained on the second paragraph of the description, this approach will not be accepted on Redmine. I personally see one big downside now (I defended this approach in the past): If an user that gained access to the ticket by the observer mechanism clicks 'Unwatch', he irreversibly looses access to the ticket. That's not acceptable and that's why I created this ticket to ask for a 'Involve mechanism' very similar to the Observe mechanism.

This is more reasonable for now, but I don't know how to create plugins.

Ok, let suppose feature 'Involve' will be done.
What should redmine do when some customer ask to uninvolve from issue?
I suppose he should loose access to the ticket. Should he?
to stop confuse only one additional feature required to be added to attached patch:

When customer click "unwatch" redmine should check - this customer loose access after this action and if so - show new additional dialogue like this:
*Attention! unwatch will looses access to the ticket. Continue?*

So i think redmine should use "Watcher mechanism" and should not do new "Involve mechanism".

I think that involved should not uninvolve himself.

And what if you want to involve someone, but don't want to have this person being notified by email? There is no way to do that using only one mechanism.

I see your point, and that was my point before, but I can understand why Jean-Phillipe don't like it. Using something that was designed for notification purposes to access control is kind of a hack and will have its limitations.

I like this patch, and I'm using this on my redmine instance, and I say thanks to the author, but I understand if it's no integrated at any time.

Bruno Medeiros wrote:

Can you describe real case how it can be: 'Guy was involved but should not notified' ?
current settings about email notification "here":http://www.redmine.org/my/account says:
1. For any event on all my projects
2. Only for things I watch or *I'm involved in*
3. Only for things I am assigned to
...

So if you are involved - you should receive emails - it's like you watch.
If you watcher - you are involved.
It's *easy to understand* and easy to code.

In other way let me suppose involved and watched are different things.
I see many problems in this way like:
1. Guy is watcher but has no permission - somebody think they receive message but actually not
2. It's possible to set watchers in time of creating issue but probably watcher has no permissions...

So i see only one issue - 'unstar' with lose permission - but my solution i mention in comment above

In other words:
What is goal for involving somebody?
*Goal is to notify him* when hidden issue is changed. *Goal is to allow him see* hidden issue changes.
So watcher = involved i think

Let me know if i miss something

Yes, you missed. Involve someone doesn't necessarily mean that you want this person being notified *by email*. You may want to let this user only access an issue when he *wants to*, not notifying him *every time* the issue is changed. You're simplifying things to much considering that involve = observe.

If somebody assign issue to you it means you will be notified every time about changing in this issue. Is it problem? I think no.
So when somebody set you as watcher - you also will be notified about every changing in this issue.
I can't to find real usacase when i need to involve sombody to issue (from closed project!) without notifying them about changing issue.
If i assign issue from closed project to some guy then him will be notified about every changes, right?
--------------------------------------------------------------------------------
I completely agree with -Bruno Medeiros- Maxim Nikolaevich. Watcher = involved, involve = observe.
For my project this feature is key feature. Only inability to give personal access to private issues blocks upgrade of Redmine from 1.3 to 2.x (with lot of fixes and new features).
I can not organize customer's workflow without this feature.

Dear developers, can you summarize status of this issue?
--------------------------------------------------------------------------------
> I completely agree with Bruno Medeiros. Watcher = involved, involve = observe.

Bruno Medeiros has different point of view. Bruno Medeiros tell ut these should be different settings. So it's strange that you are agree but tell my point of view about this things.
What you want to tell really:
1. You agree with me
2. You think watcher should be not equal involved, and involve shuuld be not equal observe.

> Dear developers, can you summarize status of this issue?

I tottaly agree. Dear developers please give us your plans about this issue.

--------------------------------------------------------------------------------
Maxim, you are right. I just copied a wrong name to my post.
So, my main idea is "Watcher = involved, involve = access". I see no reason to "watch" something and have no access to it but gets only notification mail about it with, actually, all same information, but packed in e-mails.
Or "be involved" but get no notification mails.
"Be envolved" mostly means "have access and get notifications" and Redmine should provide it in this way.

Attached is the patch for version 2.1.

The original patch resolve not only watchers for private issue.
It is also resolve, watchers not able to view non-public projects issues when they are path of the watchers list.

I am wondering why Redmine developers are not integrating this patch.
Does it cause any other bug or slow down the query?

This would significantly aid the use of Redmine in a Help Desk situation. Honestly, the "view Issues Created by or Assigned to" should include "or Watching."

Men, I believe you're missing the main point here. I created this ticket because Redmine developers rejected the idea of using observe mechanism to do access control.
I said it before and I'll say it now again: As user, I agree with you and I use the patch that is being maintained here. Using the already existing observe mechanism to involve people is reasonable.
But, as a developer, I can understand why Redmine developers don't want to integrate this patch.

Please, let's stop asking something that has already been rejected by Redmine developers. it will only bother them.

> > Dear developers, can you summarize status of this issue?
>

The status is implicit: Implement a involve mechanism, apart from observer mechanism, and it can be considered to be integrated on Redmine.
Or we can maintain this patch in parallel forever (many thanks for who is doing that now, I'm a very happy user of this patch :) ).

So developers rejected this patch because, it does not solve one very important usecase (which i describe above):

So i agree without additional dialogue this feature should not be used in production. (like this patch allow)
But i think this dialogue not so hard to code

This isn't the only issue with the current patch/approach. I will list all the problems I see now (again):

# _Unwatch make user irreversible lose access to ticket_ - This is the first issue people first realized, and maybe the biggest issue in this patch. And I don't think create a dialog fixes the problem. Make a confirmation dialog would create a big inconsistency: If I click unwatch in a ticket that I have access granted by "normal" rules, I turn off email notification for this ticket. If I do that with a ticket that I'm involved, I lose access? That doesn't make sense at all.
# _Be involved *not equals* watch_ - This is a fact. If they seem the same for you, you need less from Redmine than other people would. A watcher needs to be involved, but involved people don't necessarily need to watch. Like I said before: *Involve someone doesn't necessarily mean that you want this person being notified by email*. You may want to let some user only access an issue when he wants to, not notify this user every time the issue is changed. You're simplifying things to much considering that involve = observe.
# _Permission control needs to be separated_ - We have today 3 permissions: Add watcher, Remove watcher, See watchers list. Using observe mechanism to involve people implies that every role that is able to add/remove watchers will be able to involve/uninvolve people. This would be a design failure. We need separated permissions for involve.
# _Watch mechanism was designed for *notification* purposes_ - And when I say mechanism I don't mean only the option to watch/unwatch a ticket, I mean this combo on the ticket screen, plus all the permissions to allow different roles to add and remove watchers, plus all tables in the database, mail senders, etc. All this was designed thinking of notifying people with emails about changes, not control access. If Redmine develorpers decide to use this mechanism to control access to tickets, this could bring problems to the project in the future.

And before people start to say again that I'm against this patch: *I'm not against this patch, I'm a very happy and thankful user of it. I just understand why Redmine developers refuse to integrate it.*

Hey,

thanks for the new patch, i tried it, but it does not work :(
Any ideas?

I have tried it on Redmine version 2.1.0.
I don't know whether it will work on other version or on the latest svn checkout.

I met the same question, add a watcher means u want notify the issue's change to the watcher.

--------------------------------------------------------------------------------
Because many people seem to need this. I propose to set this as a candidate for the next major release. Maybe Jean-Philippe would disagree, but this is just a proposal. :-)
--------------------------------------------------------------------------------
As I suggested in #12666, I think a clean way to do this would be, when creating a custom field and setting the type to 'user', having a check box for enabling involvement in the issue. Coupled with multi-select, this lets you have as much or as little control over how users are involved in an issue as you need.
--------------------------------------------------------------------------------
I have updated the patch for v2.2.3 of redmine. It appears to be working fine for me. Please let me know if you experience problems with it on 2.2
--------------------------------------------------------------------------------
It turns out that patch has a subtle defect. Attempting to sort on Assignee or any other user-based column would result in no data being returned. After much debugging, I think I've found a resolution. For the technically inclined, I've moved from eager loading the :watchers association to using an explicit LEFT OUTER JOIN via a :join parameter/method.

It's not obvious to me at all why this was breaking with watchers as an include, and I suspect the way I've done this is a touch ugly (It's certainly not very DRY), but it works at least. I really wish the proper "Involve" functionality were in place so we could end of life this tweak.

Anyhow, corrected patch attached.

I suppose there is a problem because of double-quotes (") instead of back quotes (`) around some table/column names:

LEFT OUTER JOIN "watchers" ON "watchers"."watchable_id" = "issues"."id" AND "watchers"."watchable_type" = 'Issue'

I tried to modify your patch according to this (attaching). I will keep testing it.

--------------------------------------------------------------------------------
Stanislav, thanks for the report. However, it turns out there are other problems with the patch I put together. I use/test on postgres, so the issue you experienced must be due to that difference. Regardless, the change I put together is bad. It will break pagination on large issues lists in that pages will have fewer results than expected and you'll end up with inaccessible issues. (This is because the join that I added causes the query Rails/Redmine issues to the database to return duplicates)

So, instead, I've modified the patch to work differently. Instead of attempting to :join or :include the watchers relation, I've gone with fetching a list of watched issue ids by the given user, and then adding those issue ids to the WHERE clause on the SQL conditions. This seems to work much better, and is less invasive (in particular we no longer have to modify the app/models/journal.rb file)

I think this updated patch may solve both our issues. To be honest, I'm surprised past versions of this patch didn't have similar issues. Make sure to apply this against the pristine sources, and not against a previously patched version of the code. (revert app/models/issue.rb and app/models/journal.rb)

Patch attached.
--------------------------------------------------------------------------------
I hate to update my own patch in less than an hour, but I found a slightly cleaner way to do what I did. So, alas, here is FIXED_4. It's not, functionally, any different than FIXED_3 but the code is a bit cleaner.

After removal of the patch, everything works fine.
How can I fix this?
--------------------------------------------------------------------------------
Oh, interesting. I believe the problem is there are no issues being watched by those users. I don't have a good way to test this right now. Can you try this to verify for me?

Take one of the users with this issue and have them watch a single issue. If the problem goes away, I think I know how to fix it. If not, let me know.
--------------------------------------------------------------------------------
OK, I've been able to reproduce in my environment. This patch should fix that issue. We now only insert the watched issues.id clause when there are actually watched issues for the user. Let me know if you run into anything else.

Justin, I tried your last patch and it seems to work (still using mysql).

Btw, I've also tried the original patch (private_issue_watchers_2.2.diff) and haven't been able to reproduce the problem. Can you tell me the exact way how to do that?
--------------------------------------------------------------------------------
Does the patch work with Redmine 2.3.0?
--------------------------------------------------------------------------------
Given that 2.3.0 was just released two days ago, I'd say there's at best a 50/50 chance of it. Feel free to post an updated version if it doesn't.
--------------------------------------------------------------------------------
Justin Hahn, thank you for the patch , i tried it (private_issue_watchers_2.2_FIXED_5.diff) and it works when i create the issue -but not when the issue its already created and watchers are added. Using redmine 2.2.3.-

Works ok
--------------------------------------------------------------------------------
The patch seems working with 2.3.0.

--------------------------------------------------------------------------------
I've made a plugin for the 1.4.x version: http://www.redmine.org/plugins/redmine_extended_watchers

It also disables adding watchers foreign to the project. It seems weird to me the possibility to be watchers and not being able to inspect and be notified about some issue, in private projects.

Probably this aspect needs fix with public projects; any contribution is appreciated
--------------------------------------------------------------------------------
I've just upgraded my Redmine to 2.3 and installed the plugin. So far, so good!
One downside I see on the plugin approach is that some fragments of the core are copied in the plugin, and there will be no conflict if the core changes. Any thoughts on this?
--------------------------------------------------------------------------------
Hello,
private_issue_watchers_2.2_FIXED_5.diff and redmine_extended_watchers plugin have same effect and they works well.
But watcher search function does not work during the adding new watcher when you use one of them ??

Unfortunately after patching issue.rb on Redmine 2.5.0 stable I have an Internal Error 500 when I want to update issue. More strange is that after reverting changes, error still appears. Apart of this error, patch doesn't make issues visible for watchers.
--------------------------------------------------------------------------------
Hi,

I had the same error as Konrad on my Redmine 2.4.2 (working on Bitnami VM). Updating the patch helped. I attach the patch working in my 2.4.2 version (maybe it will also work in 2.5.0?).
--------------------------------------------------------------------------------
Thank you Krzysztof. It's working on 2.5.0.
--------------------------------------------------------------------------------
this patch is not working on our version , i am trying to patch redmine 2.5.1.stable

I getting the following outup

I can confirm that this patch also works for @3.2.3.stable.15464@ and should be included as a feature in the next release.
This would be very useful!

I want this feature, but I think any patches that uses watchers for access controlling purpose would not be accepted for now.

The following is Jean-Phillippe Lang's comment from #7412#note-13:

> watchers were designed for notification purpose only. A user who unwatches a private issue would lost access to it. It may be quite confusing for many users.

See also #14318#note-23.

So we should think different approach.

Okay, agreed. But Redmine really needs a solution for that!

While testing the patch @private_issue_watchers_3.1.x.diff@ with Redmine 3.2.3 I found a bug which allows users to view tickets they are not assigned to or which they aren't watching.
So I wouldn't recommend using the patch in production!
--------------------------------------------------------------------------------
For those of you who need the functionality right now, I suggest to use the patch @allow_watchers_and_contributers_access_to_issues_3.2.0.patch@ by Fabrizio Sebastiani from #14318#note-22. It works well for @3.2.3.stable.15464@.

However, I still agree with Go MAEDA that we need another/better solution for implementation in one of the next releases...
--------------------------------------------------------------------------------

We've had similar requests to this at Planio numerous times and we've spent quite some time internally thinking about better or alternative ways. Yet we couldn't come up with anything simple that wouldn't make things even more confusing for users. Being able to set people as watchers AND being able to "involve" users via two different buttons seemed to be causing even more confusion unfortunately.

So, we've implemented this based on watchers for Planio and it seems that users "get it". We're not receiving many support requests by people who are confused by the new feature.

Felix has posted the patch in #23546 for everyone's consideration :-)

Jan, I'm a happy Planio user and at the same time my company develop a custom solution based on Redmine. I see your point and I use this patch in quite a few Redmine instances. As a Redmine core developer, though, I wouldn't accept it on core, exactly as Jean-Philippe stated. I wonder if it is really a good idea to have it on Planio core.

The main problem with this patch, reported by a few of our custom solution's customers, is: *Once you are involved in an issue* (in this case, using the observe mechanism) *you cannot stop receiving emails from that issue*. If you stop observing, you lose access. If you keep observing, emails keep coming. If you reach that point, there is no way back. No solution. Period. And this is kind of obvious, because this patch uses something designed to handle email notifications to do access control, which is wrong by design.

Besides that, if you allow a role to add observers, this role is also allowed to give access to users that may not be supposed to have access. "Add watchers" permission becomes much more powerful and dubious.
See "my previous comment":/issues/8488#note-105 for more details.

I think a lot of people demand that because they don't care about losing the observer mechanism, this is a valid way, but we need to accept one thing: Observe and be involved are different things, we cannot fully resolve the problem with only one flag. If you drop the observe feature and transform it in an involve feature (I think that is what most people that use this patch do), that's fine, but keep in mind that you may be creating a bigger problem for you if people want to use the observe as it was designed to work.

Maybe we should understand what it is to be a watcher differently. Nowadays, and I may be wrong, being a watcher means I _could_ be notified via email: in "my account" I choose to be notified in combos regarding my involvement with the issues. I can not specify what changes I want to be notifyed about, neither select which level of involvement triggers notification individually. Neither I can choose to silence specific issues. Actually, users end up resorting to email filters to complement this lack of control in Redmine.

So, what really would I like to have? Let me try and design something simple, that people should "get":

* In "my account", a user should be able to choose which events to be notified about by email;
** It could be the selected subset from Administration > Settings > Email notifications;
** Not in a combo. Make each kind of notification specific.
* In "my account", a user should be able to choose if i should be notified if I am the owner, involved...
** Not in a combo. Make each kind of notification specific.
* Redmine should have a way to give unrelated people access to issues (IMO, this *is* what people understand as _watching_);
** Some roles could give more people access to the issue;
** Give view access to the issue should be the default feature.
* Receive email notifications should be a separate option:
** When seeing an issue, the user can see if they are receiving email, show in the side panel;
** Users set the default value in "my account";
** Users could add themselves to a whitelist (for each issue) to receive emails;
** Users could add themselves to a blacklist (for each issue) to receive emails;

PS:

* If the user loses view permission to an issue, remove him from the issue whitelist or blacklist.
* Please, do not redirect him out of the project, to an error page, back link not working;
** Error 404: tell user also he may not have access to page.
* When migrating the database, whoever would be in an issue watcher list, should be added to its whitelist.

Thanks for this patch!
I was looking for a solution to this problem for a very long time.

But if use patch for 3.1.X on redmine 3.3.X show up bug: All users can see issue by direct link like this http:/[redmine_url]/issues/[issue_number]
We can fix it next code in patch:

+ #self.author == user || user.is_or_belongs_to?(assigned_to)
