ActiveScaffold rails 5.2 example (jquery stuff not working)

[mvargo]

Does anybody have a simple sample rails 5.2 app with active_scaffold that I could look at?

TL;DR

I have a project I've been working on for years using rails 3.2.21 using activescaffold.  Trying to upgrade the whole thing to rails 5.2

Created a new blank rails 5.2 project.  Added activescaffold gem.  Followed directions on Getting Started.

gem 'active_scaffold' in Gemfile

add *= require active_scaffold in application

add 

//= require active_scaffold    to application.js.  

generated a model using rails g active_scaffold

All works great.  I can go to localhost:3000/dorks (the model was named Dork).  I see the scaffold list!  great.  When I click on the create new I see the ajax call to the server complete using Inspect in the browser.  The form stuff is in there.  It's just like the ajax call is not updating the DOM.

Not sure how to diagnose.  I'm sure this is just something wrong with my assets or something.  

Application.js:

//= require jquery

//= require rails-ujs

//= require active_scaffold

//= require activestorage

//= require turbolinks

//= require_tree .

Application.css:

/*

*

*= require_tree .

*= require_self

*= require active_scaffold

*/

Can you try with master branch, or 3.6.0.pre? Support for rails 5.2 were added to ActiveScaffold 3.6 which is not released yet (but I think it's pretty close), although older versions had requirement for rails >= 4.0.5 only, when issue with rails 5.2 was reported requirement was changed to >= 4.0.5 and < 5.2, so you got latest 3.5.x without rails < 5.2 requirement.

 

3.6.0.pre has a fix for rails 5.2, and a fix when rails-ujs is used instead of jquery-ujs. You could try changing rails-ujs with jquery-ujs if you don't want to update to 3.6 version, although I would recommend to update to master branch, which has fixes and improvements over 3.6.0.pre and it's stable and pretty close to release. 3.6.0 should work with rails-ujs.

I followed Sergio's advice.  I got it to work with Rails 5.2.  I put my sample app up on github if that helps anybody.

BTW:  I did try 3.6.0.pre but I got an error when trying to load the page.  master branch works.

BBTW:  I have noticed with all the versions I've tried that if you try to run rails test you get errors in the test file generated by the scaffold on the create and update tests.  I'm not sure if this is some kind of issue with the default model or what.

```

Error:

ArticlesControllerTest#test_should_update_article:

NoMethodError: undefined method `each_with_object' for nil:NilClass

    test/controllers/articles_controller_test.rb:37:in `block in <class:ArticlesControllerTest>'

```

(I wish we could have markdown everywhere.  :(
