Rails Asset Pipeline problems with jquery-ui

问题

Update

I downloaded the latest version of jquery 3.1 and jquery-ui from the jquery website. Unluckly this problem with the .effect() function is not connected to the asset pipeline. I had all the required js and css files included, but .effect() would not work.

This problem is only related to Jquery-ui, while jquery methods work fine. I am giving up on this, doing a git checkout and I will not use Jquery-ui effects for now.

Summary

My asset pipeline was working fine, but as I wanted to use jquery-ui .effect() function, I noticed problems with the jquery-ui.css stylesheets from my browser console.

I tested this function outside of the rails environment with 1.12.1/jquery-ui.js and it worked. I can display the jquery-ui.css file at http://localhost:3000/assets/jquery-ui.css.

I did the following:

As my jquery-ui.js file also was empty I required //= require jquery2 in my application js. This solved the problem with jquery-ui.js
As jquery-ui.css file was missing I did the following:
run rm -rf public/assets deleting the file in that folder (I also tried with rake assets:clean)
run rails assets:precompile in development and production
clearing the browser cache and using chrome anonymous browsing

This did not fix anything, but I can see the file and in production this problem does not exist. The application.css file includes the jquery-ui.css. So maybe the .effect() is not working for the css, but for missing js files? The effect does not work in production also.

Please follow the link above, with chrome you can test this function in the application.js file at line 18610, set a breakpoint and see that the <a id="signupFacebookButton"> does not bounce. The effect is triggered by clicking on the big bottom "sign up with facebook".

I thought maybe I do not have the bounce effect, but I can see that file included in Development and I suppose that is not the problem. Mozilla give me the following error "http:localhost:3000/assets/jquery-ui.self-fingerprint.css can not be loaded" (i did not clear mozilla cash).

This is all what I know, the version of jquery I am running is v2.2.4 which is compatible with JqueryUi. My jquery-rails gem version is 4.2.2, while my jquery-ui version is the following '~> 6.0', '>= 6.0.1'.

Documentation

I have read and followed the instructions of the following posts Rails Assets Precompile just not working

I read this one, but I did not run rm Gemfile.lock. Can't find 'jquery-ui' Rails 3.2

Maybe my next step now will be performing a Git and trying to just include the jquery-ui files manually in my project.

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")

end

回答1:

I solved this problem by creating a testing controller with a specific layout.

Read more hear to create a specific layout rails assets in production not served (yet another assets issue)

In this layout I would use cdn version of jquery and jquery-ui and as it would work with CDN and not with the jquery-ui gem, I understood that a first problem was with the gem.

Downloading jquery-ui (which included also jquery files) and including jquery and jquery-ui in my vendor/assets/javascripts and stylesheets solved the problem

The other javascript files would not cause any other problem, but using this testing controller to test also the stylesheets, I discovered that a specific custom css stylesheet was breaking the jquery-ui effect.

I could solve this problem by removing the stylesheet, but a lot of nice effect where there included (as I am using a layout).

At this point i just started with chrome developer tools to uncomment all the css properties that the link had, so that I found out, by testing the effect which property was creating problems

For example the css property that did create conflicts was with the a tag

a {
    color: #28c3ab;
    -webkit-transition: all .2s ease-in-out;
    -moz-transition: all .2s ease-in-out;
    transition: all .2s ease-in-out;
}
