No route matches [GET] “/users/sign_out”

阅读更多关于 No route matches [GET] “/users/sign_out”

Here is my actual error: No route matches [GET] "/members/sign_out" Since most people will use "users" I thought it would be more helpful to have that in the title. At any rate, I am essential unable to logout. I can successfully edit my member profile. I am using devise 1.4.2 and Rails 3.1.0.rc4. Also, I have generated two separate devise models - one called "members" and the other called "admins". I was able to register and log into both of them (simultaneously) by manually navigating to the correct URL path (i.e., localhost:3000/admins/sign_in/). I created some links within my application

Rails asset pipeline: Standard way for including all /vendor/assets/javascripts/?

阅读更多关于 Rails asset pipeline: Standard way for including all /vendor/assets/javascripts/?

I've been transitioning an app to Rails 3.1 (and now on to 3.2) and watched the Railscast on the asset pipeline . I moved all of my third-party jquery plugin files to the /vendor/assets/javascripts/ directory. In my /app/assets/javascripts/application.js I have the following: //= require jquery //= require jquery_ujs //= require_tree . //= require_self I realized the require_tree . call only loads the tree for the /app/assets/javascripts/ directory. (Is that correct?) What's the best way to include all the "vendor" javascripts? (I'm not worried about ordering at this point.) Of course I could

Best way to highlight current page in Rails 3? — apply a css class to links conditionally

阅读更多关于 Best way to highlight current page in Rails 3? — apply a css class to links conditionally

For the following code: <%= link_to "Some Page", some_path %> How do I apply a css class current using the current_page?‎ helper method? Or if some other better way is available? In app/helpers/application_helper.rb def cp(path) "current" if current_page?(path) end In your views: <%= link_to "All Posts", posts_path, class: cp(posts_path) %> Basically write a simple wrapper around it. Additionally you could extend the method to allow additional classes to be applied by adding arguments. Keeps the views concise/dry. Or, without extending the method, you could just do simple String interpolation

Application controller class ApplicationController < ActionController::Base protect_from_forgery def after_sign_up_path_for(resource) show_cities_path(resource) end end registration

Speed up assets:precompile with Rails 3.1/3.2 Capistrano deployment

阅读更多关于 Speed up assets:precompile with Rails 3.1/3.2 Capistrano deployment

My deployments are slow, they take at least 3 minutes. The slow Capistrano task during deploy is assets:precompile. This takes probably 99% of the total deploy time. How can I speed this up? Should I precompile my assets on my local machine and add them to my git repo? Edit: Adding config.assets.initialize_on_precompile = false to my application.rb file dropped the precompile time with half a minute, but it is still slow. tommasop The idea is that if you don't change your assets you don't need to recompile them each time: This is the solution that Ben Curtis propose for a deployment with git:
