Rails-通过资产管道加载资产

Question

I am trying to set up asset pipeline on a older rails app that i have so that i can start using CoffeeScript. i am using ruby 1.9.3-p327 and Rails 3.2.13. I used to stash all my JS, CSS and my images in the public/ folder. This is what i have done so far ->

1. I moved them all to app/assets, i added the manifest files for both JS and CSS call //= require_tree . .

2. Added the following gems

    group :assets do gem 'coffee-rails' gem 'uglifier' gem 'sass-rails' gem 'therubyracer' end 

3. Removed all my javascript_include_tags except for = javascript_include_tag 'https://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js'

4. Added the following to my config/application.rb file

    # Enforce whitelist mode for mass assignment. # This will create an empty whitelist of attributes available for mass-assignment for all models # in your app. As such, your models will need to explicitly whitelist or blacklist accessible # parameters by using an attr_accessible or attr_protected declaration. config.active_record.whitelist_attributes = true # Enable the asset pipeline config.assets.enabled = true # Version of your assets, change this if you want to expire all your assets config.assets.version = '1.0' 

5. Within the config/environments/development.rb file set

    # Do not compress assets config.assets.compress = false # Expands the lines which load the assets config.assets.debug = true 

6. I added to the config/environments/production.rb

    # Compress JavaScripts and CSS config.assets.compress = true # Choose the compressors to use # config.assets.js_compressor = :uglifier # config.assets.css_compressor = :yui # Don't fallback to assets pipeline if a precompiled asset is missed config.assets.compile = false # Generate digests for assets URLs. config.assets.digest = true # Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added) # config.assets.precompile += %w( search.js ) 

I re-read the section on the Asset Pipeline just to see if i messed up anything. But so far none of the assets are pulling through from app/assets the only one that is working is the jquery.min.js that i have coming in through include_tag i have tried removing it and trying again no dice.

I have tried bundle exec rake assets:clean , and bundle exec rake assets:precompile , both of which run without issues. and have bundled since adding the gems for the assets, and restarted pow each time.

I am not sure if i am going through this all wrong or i have missed a step? any one gone through this before and tips or clues would be much appreciated.

Answer 1

You said you removed all the javascript_include_tag statements. Assuming you named the manifests app/assets/javascripts/application.js and app/assets/stylesheets/application.css , you'll need to include those in your layout:

<%= stylesheet_link_tag    "application", :media => "all" %>
<%= javascript_include_tag "application" %>

Otherwise, Rails won't know to load your manifest files

Also, you shouldn't be using rake assets:precompile in development. If you do, then anytime you change a JS/CSS file, you'll have to recompile the assets before your changes show up.
