Feature: adding rake tasks to engine

[onemanstartup]

When I'm add bower-rails to engine there is no rake tasks.

Checkout #39

@cj, @onemanstartup You can do the following in your Rakefile:

spec = Gem::Specification.find_by_name 'bower-rails'
load "#{spec.gem_dir}/lib/tasks/bower.rake"

Then try rake -T

[onemanstartup]

@SergeyKishenin thanks, now i have rake tasks, but they only work on dummy app. even when I call tasks like rake bower:install
rake app:bower:install - works the same way.

[SergeyKishenin]

Does rake -T at your engine root say that you have bower's tasks?

[onemanstartup]

Yes.

I've inserted like this

spec = Gem::Specification.find_by_name 'bower-rails'
load "#{spec.gem_dir}/lib/tasks/bower.rake"
Bundler::GemHelper.install_tasks
APP_RAKEFILE = File.expand_path('../test/dummy/Rakefile', __FILE__)
load 'rails/tasks/engine.rake'

then i have
rake bower:install
and then Bowerfile from engine/test/dummy/Bowerfile used

[SergeyKishenin]

Well, I'm not sure what's wrong with your engine. I've just tried the same and all was fine.

My engine's Rakefile looks like:

#!/usr/bin/env rake
require 'bundler/gem_tasks'
require 'rspec/core/rake_task'
require 'bower-rails'

spec = Gem::Specification.find_by_name 'bower-rails'
load "#{spec.gem_dir}/lib/tasks/bower.rake"

RSpec::Core::RakeTask.new(:spec)

task :default => :spec

rake -T at the engine's root produces:

$ rake -T
rake bower:install        # Install components from bower
rake bower:install:force  # Install components with -F option
rake bower:list           # List bower components
rake bower:update         # Update bower components
rake bower:update:prune   # Update existing components and uninstalls extraneous components
rake build                # Build xxx-0.2.3.gem into the pkg directory
rake install              # Build and install xxx-0.2.3.gem into system gems
rake release              # Create tag v0.2.3 and build and push xxx-0.2.3.gem to Rubygems
rake spec                 # Run RSpec code examples

My engine's Bowerfile contains just asset 'moment'. rake bower:install at the engine's root installs moment to vendor/assets/bower_components as expected. Just make sure you have /vendor/assets dir.

Just to test I've created Bowerfile at dummy's root that contains asset 'backbone' and it was ignored when I run rake bower:install at engine's root and evaluated for the same command at dummy's root. As expected.

So make sure you have everything all right! Good luck :)

[onemanstartup]

You don't have

APP_RAKEFILE = File.expand_path('../test/dummy/Rakefile', __FILE__)
load 'rails/tasks/engine.rake'

https://github.com/rails/docrails/blob/master/railties/lib/rails/tasks/engine.rake - this file load dummy rails and your rake task set root to that dummy app

[SergeyKishenin]

Are you sure that dummy's Rakefile should be loaded to engine? Maybe engine's one to dummy?

[onemanstartup]

It is default behaviour, when you generate mountable engine
rails plugin new engines/engine --mountable
and this rails/tasks/engine.rake file add app namespaces rake tasks(which belongs to dummy) to engine folder.
P.S. можно и по русски :)

[SergeyKishenin]

Yes, I see now. Let me check out.

PS: по-русски тут неформат немного :)

[SergeyKishenin]

Check out the edge version

[onemanstartup]

Now I have this issue

# Bowerfile
assets_path "assets/javascript"

# Puts files under ./lib/assets/javascript/components
group :lib, :assets_path => "assets/js" do
  asset "jquery"
end

Fixed with 8465b06

[onemanstartup]

It's working, thanks.
