Rails jquery-fileupload gem - couldn't find fi

Question

I'm trying to follow the Railscasts episode on jQuery-FileUpload. I've added

gem 'jquery-fileupload-rails' 

to the assets group of the Gemfile, and also added the

//= require jquery-fileupload/basic

line to the application.js file in the asset directory. When I try to bring up the website, however, the following error is shown:

couldn't find file 'jquery-fileupload'
  (in root/app/assets/javascripts/application.js:15)

Any help would be greatly appreciated.

Answer 1

That's really weird, I just tried with a Gemfile:

source 'https://rubygems.org'

gem 'rails', '3.2.12'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'


# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  gem "jquery-fileupload-rails"

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

and on application.js

//= require jquery
//= require jquery_ujs
//= require_tree .
//= require jquery-fileupload/basic

and worked great, did you run bundle ? I know its a stupid question but it may be

Answer 2

Remove it from assets group, and it'll work fine.

Answer 3

I think you wanna add the following line to application.js

//= require jquery-fileupload 

Answer 4

I found a "solution" - restarting rails server did the trick.

Answer 5

I ran into something similar lately. What worked for me was to load the gem directly from git

gem 'jquery-fileupload-rails', git: 'git://github.com/ollnixon/jquery-fileupload-rails.git'

And then to load the the needed ui styles

*= require jquery.fileupload-ui

Works flawlessly now

Answer 6

I have fix this by :

add

gem 'therubyracer'
gem 'execjs'

to your Gemfile.

and run bundle install and rake assets:precompile --trace RAILS_ENV=production
