在 rspec 文件中，我得到 => Error: ActionController::RoutingError: No route matches xxxxxxx despite valid routing

Question

我对测试和 Rails 都非常陌生（不到 1 年的经验）。 在回答之前请记住这一点。

我有一个属于source的模型recipe ，而source属于client 。

路线是：

client_source_recipes GET /clients/:client_id/sources/:source_id/recipes(.:format) recipes#index

我正在尝试测试这个：

RSpec.describe RecipesController, :type => :controller do

# Prerequisites go here (mentioned at the end of the question)

  describe "GET #index" do
    it "assigns all recipes as @recipes" do
      recipe = Recipe.create! valid_attributes
      get :index, params: { client_id: client.id, source_id: source.id, locale: 'cs' }, session: valid_session
      expect(assigns(:recipes)).to eq([recipe])

      # Commented below are different ways I tried but failed:

      # visit client_source_recipes_path(client.id, source.id, locale: 'cs')
      # visit "/client/#{client.id}/source/#{source.id}/recipes?locale=cs"
      # get client_source_recipes_path, params: { client_id: client.id, source_id: source.id, locale: 'cs' }, session: valid_session
      # get client_source_recipes_path(client.id, source.id, locale: 'cs')
    end
  end
end

测试先决条件：

  login_user         # defined - works well

  let(:client) { create :client }                                         # defined in factories 
  let(:source) { create :source, warehouse_id: 1, client_id: client.id }  # defined in factories

  let(:valid_attributes) {
    { name: "name", source_id: source.id }
  }

  let(:valid_session) { {"warden.user.user.key" => session["warden.user.user.key"]} }   # works well in other tests

为什么在其他地方使用相同的路线时会出现路线错误？

错误：

 Error: ActionController::RoutingError: No route matches {:controller=>"recipes", :params=>{:client_id=>"1", :source_id=>"1", :locale=>"cs"}, :session=>{"warden.user.user.key"=>[["1"], "$2a$04$bobnhLAlKEsxZtlJheY64."]}}

 Error: ActionController::RoutingError: No route matches {:controller=>"recipes", :action=>"/clients/1/sources/1/recipes?locale=cs"}

 Error: ActionController::RoutingError: No route matches {:controller=>"recipes", :action=>"/clients/1/sources/1/recipes"}

# etc. etc. i.e. errors are more or less the same

提前致谢。

好的！

我已经“花了”大约 5 个小时来思考这个问题，但无论如何都做不到，现在我发现唯一的问题是语法：

错误的（旧的）语法（期望 params 和 session 明确地作为参数）：

get :index, { client_id: client.id, source_id: source.id, locale: 'cs' }, session: valid_session

#or

get :index, params: { client_id: client.id, source_id: source.id, locale: 'cs' }, session: valid_session

正确的（较新的）语法（隐式接受参数和会话作为参数）：

get :index, { client_id: client.id, source_id: source.id, locale: 'cs' }, valid_session

我希望它能节省其他人的宝贵时间，不像我：
