rake assets:precompile not resolving

[SergeyKishenin]

Maybe I'm doing this wrong? Starting with no dependencies and running rake assets:precompile I get an error for a missing dependency. Looking at the trace, it doesn't seem like bower:install is ever called.

** Invoke assets:precompile (first_time)
** Execute assets:precompile
/Users/nic/.rvm/rubies/ruby-2.0.0-p353/bin/ruby /Users/nic/.rvm/gems/ruby-2.0.0-p353@zeumo/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets --trace

** Invoke assets:environment (first_time)
** Execute assets:environment

** Execute tmp:cache:clear
** Execute assets:precompile:primary
...

# config/initializers/bower_rails.rb
BowerRails.configure do |bower_rails|
  bower_rails.resolve_before_precompile = true
end

What am I missing?

[SergeyKishenin]

What does the error message say?

[nicinabox]

"couldn't find file ...", where file is a dependency that would be in bower_components. rake bower:install has not been run at this stage.

[SergeyKishenin]

Could you, please, try issue-72 branch: gem 'bower-rails, github: '42dev/bower-rails', branch: 'issue-72'

[nicinabox]

Same error as above.

[SergeyKishenin]

Could you test this branch again?

[nicinabox]

Hmm, no change.

[SergeyKishenin]

I've tried and had success. Have you updated gem?

[nicinabox]

Yeah, updated from issue-72 branch. I reviewed the code, and it looked appropriate. Still not seeing any difference though.

$ bundle list | grep bower-rails
  * bower-rails (0.7.1 f72fe0d)

Using Ruby 2.0.0 and Rails 3.2.17.

[nicinabox]

@SergeyKishenin Any ideas? Seems like it should Just Work.

[SergeyKishenin]

That's very strange as I have it working with Rails 4.0.4 and Ruby 2.1.1.

Anyway I have to do a fix to make rake bower:install and others to run before not after rake assets:precompile task.

[SergeyKishenin]

I've added before hook to perform bower tasks before precompilation and now have to following trace:

$ rake assets:precompile --trace

** Invoke assets:environment (first_time)
** Execute assets:environment

[nicinabox]

Confirmed working with Rails 4.0.1 with bower-rails#f0cf21f. Hmm... so Rails 3.2 not so much.

[nicinabox]

Looks like asset_sync had a similar issue: AssetSync/asset_sync#41

[nicinabox]

Following what asset_sync did, I added this file:

# lib/tasks/bower_rails.rake
Rake::Task['assets:precompile'].enhance ['bower:install', 'bower:resolve']

And it works. Check out this commit for reference.

[SergeyKishenin]

Well, does this invoke bower-rails' tasks before precompilation? With Rails 4.0.4 it did after, actually.

[nicinabox]

Seems to.

** Invoke assets:precompile (first_time)
** Invoke bower:install (first_time)
** Execute bower:install
bower.js files generated
/Users/nic/.nvm/v0.10.22/bin/bower install
** Invoke bower:resolve (first_time)

** Invoke assets:environment (first_time)
** Execute assets:environment

** Execute tmp:cache:clear
** Execute assets:precompile:primary

[SergeyKishenin]

I've just found that with Rails 3.2.x BowerRails.tasks are empty as the rake assets:precompile is performed before the app initialization.

[nicinabox]

I also found that a little bit ago!

[SergeyKishenin]

Well, as a workaround I placed bower-rails' initializer code to application.rb and it seems to work. But I find this not the best solution. Any ideas?

UPD: or require initializer in application.rb like require "#{Rails.root}/config/initializers/bower_rails.rb"
