counter_culture | Turbo-charged counter caches for your Rails app | Application Framework library

Currently Ruby 3.0 is not supported with Rails, as there will be next release for Rails. You can do following and it works by installing dev branch of ruby 3. I used ruby 3.1.0dev (2021-02-14T05:09:08Z master ff527e7e32) [x86_64-darwin19] Following commands are with RVM you can use same with other softwares I tried by installing

Short answer is no. You cannot use post.update(authors: []) and trigger callbacks.

counter_culture gem that you provided builds its functionality on top of rails callbacks execution, I pointed in that url code which does it.

post.update(authors: []) this code doesn't trigger ActiveRecord callbacks.
Neither this one post.authors.find(1).delete.

So in order to trigger your callbacks and update counter_cache column, you will need to write some function that will resolve authors and trigger destroy

Consider this

At the end I just decrease it manually in the same query that change from active to inactive. If someone knows the correct answer it will be useful next time.

You just shared the Gem file, but nothing how this app is developed, so it is insufficient information to give you an accurate response. But usually, two different methods are followed.

Two separate application, as your ruby on rails application working, can create another react application, and consume all endpoints present in your Ruby on Rails application, if you could not find some require endpoint, you can check already made endpoints and make few new one following the way. Hopefully, it would be easier to do.

In this method, you have to break apart your project and removing all Angular Gems already present in your project and start with fresh frontend with ReactJS. In my opinion, it requires much more Ruby on Rails knowledge to do it, but in the end, you will get just one project.

As from Gem file seem it is heavily using Angular, so probably you have run it and check if it has most of the Endpoints made Restful. If yes then I suggest to go on method one and create new ReactJS app, which will consume all endpoint made in Ruby on rails, that would be more work on React side app and less on Ruby on Rails. Even if you found that some endpoints are not present you can follow already created endpoints coding and action, where you will complete details. I understand there will be two different projects, but the learning curve to learn Ruby on Rails and integrating it with React would be more than having two different projects.

I would define this as a method on the campaign subscription class, instead of trying some kind of counter cache. I would only use a counter cache on the parent model to describe counts in a simple one-to-many (maybe with a filter publishedL:true), but not for counting related records in the same table. Use a model method for that:

I wouldn't use the Survey's show action to show the form to create a Response, I think it's better to approach it as a new_response action to make it cleaner and leave the show action just to show the actual survey (not to respond it). Something like:

I solved it this way.

Added the gem counter-colture, generated a migration to create on users table columnsreceived_vote_weight and sent_vote_weight.

Added to vote_weight_assignment.rb

The problem is you have used a preserved word group in defining relation

belongs_to :group creates conflict with ActiveRecord's group method http://guides.rubyonrails.org/active_record_querying.html#group.

The only solution is to use different name for the relationship

how about remove Gemfile.lock entirely and run bundle install again ;) haha
