couldn't find file 'jquery' rails 3.1 stable mountable engine

When I create a new engine in Rails 3.1 stable and then access the dummy app or the engine I get an error say that the app can't find jquery.

I've created the engine using rails plugin new coffee --mountable

I've also created a basic controller in the engine and the dummy app. If I remove the javascript include tag, everything works. But with the tag there it just bails since it can't fine jQuery. The jquery-rails gem is installed. I have jquery as a dependency in my gemspec file. I've even added an Gemfile to the dummy app just to try, but it gives the same error.

Hey Jorgen,

This isn't a solution, but it may be better to simply remove the line from your js file (Looks like #= require jquery) and use the Google CDN version:

= javascript_include_tag '//ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js', :defer => true, :async => true

This will this be faster for your users (because Google has more cloudspace than you, probably) and it also removes the need for Sprockets to compress it.

I hope you find out what's going on. :confused:

Cheers

Hi Kurtis,

Thanks for your answer. I was thinking the same thing and I'll just start developing without javascript all together since I don't need it in the initial phase.

I've also tried using and creating the engine with Rails 3.1.0rc5 and 3.1.0rc8 and I get the same error. Surely I can't be alone with geting this error?

I think I'll post an issue on Github.

At the very least it could be a good idea to include in the issue: It'd be nice to know where Sprockets was looking for the file.

I thought I would post here very quickly because I was having the same problem and utilizing the google cloud resolved the issue. Here is what it looks like now.

// This is a manifest file that'll be compiled into including all the files listed below. // Add new JavaScript/Coffee code in separate files in this directory and they'll automatically // be included in the compiled file accessible from http://example.com/assets/application.js // It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the // the compiled file. // //= javascript_include_tag '//ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js', :defer => true, :async => true //= require jquery_ujs //= require_tree .

I had the same problem and finally fixed. The solution is to explicitly require the 'jquery-rails' gem in the dummy config/application.rb file, so Sprockets can add the jquery assets in the assets.path.

In test/dummy/config/application.rb

    require File.expand_path('../boot', __FILE__)

    # Pick the frameworks you want:     # require "active_record/railtie"     require "action_controller/railtie"     require "action_mailer/railtie"     require "active_resource/railtie"     require "rails/test_unit/railtie"     require "sprockets/railtie"

    # Auto-require default libraries and those for the current Rails environment.     Bundler.require :default, Rails.env

    require "coffee"     require "jquery-rails" # this should be auto-included with the Bundler.require :default, Rails.env, but it's not happening

    module Dummy       class Application < Rails::Application           # ...       end     end

Same with other gems that have assets that should be auto-loaded by Sprockets. Hope this helps.

The solution for me was to add jquery-rails to my engines Gemfile and restart the server.

I would suspect that it does not want adding to the gemspec however, however adding it as a development dependency might be okay.
