rails active admin deployment : couldn't find

问题:

when trying to deploy with capistrano, when capistrano use command bundle exec rake

    RAILS_ENV=production 
    RAILS_GROUPS=assets 
    assets:precompile

I have this error

couldn't find file 'jquery-ui'
  (in /home/umbrosus/.rvm/gems/ruby-1.9.3-p392@gancxadebebi/gems/activeadmin-0.5.1/app/assets/javascripts/active_admin/base.js:2)

Before it was working well, but I tried to update to 0.6 and then I started to have this error. I came back to 0.5.1 and the error is still there. Do I do something bad ?

thanks

The "jquery-rails" gem recently removed jQuery UI.

https://github.com/rails/jquery-rails/commit/2fdcdb2633cbc6426d412c050200fc31d14b9a3b

They recommend using the jquery-ui-rails gem.

There is an active pull request (as of this writing) to add that gem as a dependency. However, the developers of ActiveAdmin have stated that they are "locking it down until we officially drop support for Rails 3.0". The version they are locked to is jquery-rails < 3.0.0.

In the meantime, just modify your Gemfile:

gem "jquery-ui-rails" Not recommended, see @Kevin's comment below

Or you can downgrade your version of jquery-rails:

gem "jquery-rails", "< 3.0.0"

Or you can pull from their Github master branch. They have applied a temporary fix.

gem "activeadmin", github: "gregbell/active_admin"

Well, there is no need to downgrade jquery-rails to 2.3.0 or specify a GitHub branch. Just use jquery-ui-rails. To workaround the file name differences:

Simply create app/assets/javascripts/jquery-ui.js

//= require jquery.ui.all

Create app/assets/stylesheets/jquery-ui.css

/*
 *= require jquery.ui.all
 */

These load the correct files to satisfy ActiveAdmin

Though the Pull request has been merged into AA by now, you will still have this problem if you work with the latest release of AA. I don't like to force JQuery-rails down to version 2.3.0 so here's an alternative solution to the problem: In the active_admin.js file replace

//= require active_admin/base

with

//= require jquery
//= require jquery_ujs
//= require jquery.ui.core
//= require jquery.ui.widget
//= require jquery.ui.datepicker
//= require active_admin/application

kudos to Fred for providing that solution here.

Downgrading "jquery-rails" to "2.3.0" fixed this issue for me as well.

回答5:

In my case, the jquery issue was due to a gem I was using. I wasn't using jquery directly, so adding app/assets/js/jquery-ui.js to my project didn't help.

Adding gem "jquery-rails", "< 3.0.0" to my gemfile fixed it, but I got an issue with turbolinks immediately after that, which is easy enough to fix...

My final gemfile:

# Temporary fix for jquery issue
gem "jquery-rails", "< 3.0.0"
gem 'turbolinks'

... easy peasy

回答6:

I know this is already solved. But I want to give one more solution to this that worked for me.

I am running Rails 4.0.8 when having this issue.

I simply remove explicit version number for jquery-rails gem jquery-ui-rails gem.

Mine looks like this essentially:

# js
gem 'jquery-ui-rails'
gem 'jquery-rails'

# rails admin
gem 'rails_admin'

Gemfile.lock kinda figured out the correct version for all three gems automatically.
