使用名称空间测试Rails3和Rspec2控制器

Question

我正在尝试测试一个具有名称空间的控制器，以下是我的控制器(/admin/sites_controller.rb):

class Admin::SitesController < AdminController
  def create
    @site = Site.new(params[:site])
    respond_to do |format|
      if @site.save
        format.html { redirect_to(@site, :notice => 'Site was successfully created.') }
        format.xml  { render :xml => @site, :status => :created, :location => @site }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @site.errors, :status => :unprocessable_entity }
      end
    end
  end
end

和以下是我的routes.rb文件

namespace :admin do
    resources :sites
end

我正在使用rspec2来测试我的控制器，以下是我的控制器规格

describe Admin::SitesController do
  describe "POST create" do
    describe "with valid params" do
      it "creates a new Site" do
        expect {
          post :create, :site => valid_attributes
        }.to change(Site, :count).by(1)
      end
    end
  end
end

但是当我运行规范时，它给了我以下路由错误

Admin::SitesController POST create with valid params creates a new Site
     Failure/Error: post :create, :site => valid_attributes
     NoMethodError:
       undefined method `site_url' for #<Admin::SitesController:0xb5fbe6d0>
     # ./app/controllers/admin/sites_controller.rb:47:in `create'
     # ./app/controllers/admin/sites_controller.rb:45:in `create'
     # ./spec/controllers/admin/sites_controller_spec.rb:78
     # ./spec/controllers/admin/sites_controller_spec.rb:77

我猜这是因为'admin'的名称空间，我正在使用，但我怎么能解决这个问题?

当你给路由命名时，你是在创建URL和路径帮助器，看起来像这样:

HTTP Verb  Path                     action   helper
GET        /admin/sites             index    admin_sites_path
GET        /admin/sites/new         new      new_admin_site_path
POST       /admin/sites             create   admin_sites_path
GET        /admin/sites/:id         show     admin_site_path(:id)
GET        /admin/sites/:id/edit    edit     edit_admin_site_path(:id)
PUT        /admin/sites/:id         update   admin_site_path(:id)
DELETE     /admin/sites/:id         destroy  admin_site_path(:id)

所以你可以直接在你的代码中使用这些(即redirect_to admin_site_path(@site))，或者你可以这样做:

redirect_to([:admin, @site])
