Problem using current_user.following?(user)

[nelsonlho]

I am using acts_as_follower with Devise
So I notice something funny with current_user.following?(user)

current_user.following?(user) will always resolve to false, even when it's true, unless I restart my rails server

any thoughts?

[BrahimDahmani]

what's the result of current_user.follows ??

[fdahmadi]

I had same problem with some_model.all_following and some_model.follow(another_model)
Problem is for incompatibility with Rails 5

• First use gem from github.
  in Gemfile:
  gem 'acts_as_follower', github: 'tcocca/acts_as_follower'
  and then
  bundle install
  It is in version 0.2.1 now
• In Rails 5 models inherited from ApplicationRecord
  Find "follower_lib.rb" and change line 8
  if obj.class.superclass != ActiveRecord::Base
  To:
  if obj.class.superclass != ActiveRecord::Base || obj.class.superclass != ApplicationRecord
• Then clean "follows" table.
• Restart server

excuse me for my bad english. I can't explain better.

@fdahmadi this is an old solution, this is what the code look like right now

    DEFAULT_PARENTS = [ApplicationRecord, ActiveRecord::Base]

   # Retrieves the parent class name if using STI.
    def parent_class_name(obj)
      unless parent_classes.include?(obj.class.superclass)
        return obj.class.superclass.name
      end
      obj.class.name
    end

@nelsonlho so all what you have to do is listing your parent classes to in the initializer

ActsAsFollower.custom_parent_classes = [Book, Author, Publisher, User]

[fdahmadi]

My first approach is wrong. Sorry.

In my application users can follows each other
After some time server must be restarted because parent_class_name return ApplicationRecord instead of User and table is corrupted and application crash in user.all_following and user.follow(other_user) dos't work correctly
It seems bug is not in acts_as_follows but in somewhere in Puma. I don't know.
But i do the following approach and after 3 days it is working correctly

• First use gem from github.
  in Gemfile:
  gem 'acts_as_follower', github: 'tcocca/acts_as_follower'
  and then
  bundle install
  It is in version 0.2.1 now
• Find follower_lib.rb and comment 3 lines as follow

    def parent_class_name(obj)
      #unless parent_classes.include?(obj.class.superclass)
      #  return obj.class.superclass.name
      #end
      obj.class.name
    end

• clean "follows" table.
• Restart server

It works in my app. maybe it works on your app too.

excuse me for my bad english.

I also experienced this issue on Rails 5 and believe this is solved in PR #56

Use my fork if you like:

gem 'acts_as_follower', github: 'mrjlynch/acts_as_follower', branch: 'rails_5'

[merqlove]

I think main problem within started Spring process & sometimes it's stuck.

@nelsonlho As @jeremylynch mentioned, I suspect that the merge of #56 should fix this. Does that take care of this issue?
