Journal overrides @save@ method from @ActiveRecord::Base@ like that

def save
   ...
end

while it should be

def save(perform_validation = true)
   ...
end

or

def save(*args)
  ...
end

With current definition, any call passing an argument to the save method - Journal#update_attribute for example - will raise an exception like this one:

wrong number of arguments (1 for 0)
