rake assets:precompile fails

StackOverflow https://stackoverflow.com/questions/15536380

Вопрос

I have an Rails app that is working fine in development. I'm developing it in RubyMine but I test and run it from the Terminal (files are stored/run on a Ubuntu workstation that I access with Terminal from OSX) using Webrick and sqlite3. The app uses a modified Boostrap-template and it works fine. Now I wanted to try to run it in production mode.

This is what I did: Rails version is 3.2.11, I use rvm 1.8.1 with ruby-1.9.2-p290

config.logger = Logger.new(STDOUT) in environment/production.rb
config.serve_static_assets = true in environment/production.rb
export RAILS_ENV=production
rake db:migrate (works fine)
rake assets:precompile --trace

I get the following error:

Tasks: TOP => assets:precompile

Now if I do the above on a clean rails app, it works. But it fails on my app that I thought was working. Can you give any pointers about what is wrong?

The _form.rb is btw a partial with a simple_form call, nothing special at all.

(Just two lines shown here to show where the error seems to occur)

<%= yield :title %>
<%= simple_form_for(@article, :html => {:multipart => true, :class => 'form-horizontal'} ) do |ff| %>

Any help is appreciated!

Решение

OK this turned out to be a goof by me. When solving some other asset problem a few weeks ago, I had fiddled around with (in config/application.rb) 

config.assets.paths << "#{Rails.root}/app/assets"

and accidentally added (In some desperate move I guess)

config.assets.paths << "#{Rails.root}/app"

This of course included EVERYTHING under app as assets, which was horribly wrong.

This error did show up until I had to do a rake assets:precompile. Since I didnt really have a clue what that command did, I didn't see that it was trying to compile view ERB files as assets.

After finding this article: http://blog.55minutes.com/2012/02/untangling-the-rails-asset-pipeline-part-2-production/ I realised that it was erroneously including the view files and it had to be a path problem.

Small error but very difficult to fix. Sort of the Rails standard.
