rails-routing

问题 I'm new to Ruby and Ruby on Rails, am using Ruby 1.9.2 and Rails 3.2.5 on Max OSX Lion, and am working my way through the book "Agile Web Development with Rails (4th Edition)". I've created their sample depot app using the following commands outlined in Chapter 6: rails new depot rails generate scaffold Product title:string description:text image_url:string price:decimal rake db:migrate rails server When I point Safari to "http://localhost:3000/products" I get the following Action Controller:

问题 I have a rails application that contains many user pages. When a user wants to point a domain at this page, how would I do that? Right now I've tested out this, and it works - root :to => "controller#show", :id => 4, :constraints => {:host => "www.exampleurl.com"} but need to convert this to be dynamic, so that after I migrate a column into the model called domain it checks domain and serves it the proper ID. something like - root :to => 'controller#show', :id => ':id', :constraints => {:host

问题 There are only two actions accessible in the ProductsController : # /config/routes.rb RailsApp::Application.routes.draw do resources :products, only: [:index, :show] end Tests are set up accordingly: # /spec/controllers/products_controller_spec.rb require 'spec_helper' describe ProductsController do before do @product = Product.gen end describe "GET index" do it "renders the index template" do get :index expect(response.status).to eq(200) expect(response).to render_template(:index) end end

问题 I'm trying to generate a link for a user to click to confirm their account. I'm wanting this: /users/:id/confirm/:code I've got this in my routes file: resources :users do member do get 'confirm/:confirmation_code', :action => 'confirm' end end I've tried: user_confirm_path(@user, @confirmation_code) confirm_user_path(@confirmation_code, @user) and many others but can't seem to get the right one. I guess I could always generate the link url myself but that doesn't seem the rails way. This is

问题 I followed this rails cast to create authentication for a rails project. My routes currently look like this: Rails.application.routes.draw do resources :messages get "log_out" => "sessions#destroy", :as => "log_out" get "log_in" => "sessions#new", :as => "log_in" get "sign_up" => "users#new", :as => "sign_up" get "new_photo" => "users#edit", :as => "new_photo" root :to => "users#new" resources :users resources :sessions end How to I edit this file so that the root will be pointing to

问题 I have an engine (developed by me / the company I work for) that we use on several different projects. I just converted it to work with rails 3.1 w/ assets pipeline and everything seems to be working... for the most part. My problem is that I need to extend the functionality of the UsersController with a little bit of app-specific spice, but I'm not sure about the best way to do it. The engine doesn't define a Users#show action, but this app does need it, so I added to the routes file:

问题 I'm trying to create a JSON feed for certain data to pull into a graph I have in a partial. I keep running into "Couldn't find Dam without an Id", and none of the answers on SO seem to have the fix. My params seem to be passing through fine, and I'm a bit perplexed. routes.rb require "resque/server" Rails.application.routes.draw do mount Resque::Server, :at => "/resque" root 'home#index' get 'about', to: 'home#about' resources :dams, only: [:index, :show] do get 'count_data', to: 'dams#count

问题 I am developing a app in ruby on rails for a local business. The pages are 'static', but changeable through a backend CMS I am building for them. Is there a best practice to creating a controller for static pages? Right now I have a sites controller with all static routes, like this. routes.rb get "site/home" get "site/about_us" get "site/faq" get "site/discounts" get "site/services" get "site/contact_us" get "site/admin" get "site/posts" or would I be better off creating member routes for

问题 In urls and rails routing, what is the difference between using a slash character vs a pound sign (hash sign) character? These work get "/static_pages/about" get 'about', to: 'static_pages#about', as: :about These don't get "/static_pages#about" get 'about', to: 'static_pages/about', as: :about get 'about', to: '/static_pages#about', as: :about What code controls this behavior, and what is the deeper reason behind it? ANSWER: (The two people answered it very well, and I had trouble choosing

问题 I'm curious what people consider adequate/thorough testing of routes. A guy I work with seems to want to assert every route in our routes file, no matter how standard. I feel like this is a waste of time, but maybe I'm wrong and there is some value to this I'm unaware of. There are a few cases where I can see some value in routing. We still have a couple actions that respond to both GET and POST requests, although I've been meaning to get rid of those. We don't have any kind of crazy
