自定义用户名路由的RSpec测试失败

我有一个匹配的路由,匹配这样的用户名:

controller :users, :path => '/:username', :as => :user, :constrain => { :username => /^_?[a-z]_?(?:[a-z0-9]_?)*$/i } do
   # lots of nested routes go here
end

当我为此编写RSpec测试时(与正常使用user_id相比),所有测试都失败了,因为它“无法找到路由”,即使它在服务器上正常工作。

describe "for an invalid request" do
  it "should render a 404 if an associated photo is not found" do
    # give it a bad photo id
    xhr :post, :destroy, :id => "999999", :photo_id => "999999", :username => @photo_owner.username
    # not found
    response.status.should == not_found
  end
end

当我在切换到用户名之前在路由中使用user_id时,此测试工作正常:

resources :users do
  # nested routes
end

xhr :post, :destroy, :id => "999999", :photo_id => "999999", :user_id => @photo_owner.id

那么我做错了什么,改变了什么?

我的服务器控制台显示了这一点,这意味着我应该正确传递所有参数:

Processing by TagsController#destroy as JS
  Parameters: {"constrain"=>{"username"=>/^_?[a-z]_?(?:[a-z0-9]_?)*$/i}, "username"=>"rubynewb", "photo_id"=>"2004-the-title-of-the-photo-here", "id"=>"1797"}

在路线定义中使用:constraints => {...}

你传递的参数太多了......

"constrain"=>{"username"=>/^_?[a-z]_?(?:[a-z0-9]_?)*$/i}

Rails无法识别:constrain,因此它和它的内容作为参数传递,而不是由Rails路由器处理。
