使用关联测试 Rspec 控制器

发布于 2024-08-22 06:55:26 字数 1322 浏览 3 评论 0原文

我有两个模型：

class Solution < ActiveRecord::Base
  belongs_to :user

  validates_attachment_presence :software
  validates_presence_of :price, :language, :title
  validates_uniqueness_of :software_file_name, :scope => :user_id

  has_attached_file :software
end


class User < ActiveRecord::Base
  acts_as_authentic
  validates_presence_of :first_name, :last_name, :primary_phone_number
  validates_uniqueness_of :primary_phone_number

  has_many :solutions
end

我的路线如下所示：

map.resources :user, :has_many => :solutions

现在我正在尝试使用以下 RSpec 测试来测试我的解决方案控制器：

describe SolutionsController do

  before(:each) do
    @user = Factory.build(:user)
    @solution = Factory.build(:solution, :user => @user)
  end

 describe "GET index" do
   it "should find all of the solutions owned by a user" do
     Solution.should_receive(:find_by_user_id).with(@user.id).and_return(@solutions)
     get :index, :id => @user.id
   end
 end
end

但是，这给我带来了以下错误：

ActionController::RoutingError in 'SolutionsController GET index should find all of the solutions owned by a user'
No route matches {:id=>nil, :controller=>"solutions", :action=>"index"}

任何人都可以告诉我如何测试这个，因为索引应该总是在特定用户的范围内调用？

I've got two models:

class Solution < ActiveRecord::Base
  belongs_to :user

  validates_attachment_presence :software
  validates_presence_of :price, :language, :title
  validates_uniqueness_of :software_file_name, :scope => :user_id

  has_attached_file :software
end


class User < ActiveRecord::Base
  acts_as_authentic
  validates_presence_of :first_name, :last_name, :primary_phone_number
  validates_uniqueness_of :primary_phone_number

  has_many :solutions
end

with my routes looking like this:

map.resources :user, :has_many => :solutions

Now I'm trying to test my solutions controllers with the following RSpec test:

describe SolutionsController do

  before(:each) do
    @user = Factory.build(:user)
    @solution = Factory.build(:solution, :user => @user)
  end

 describe "GET index" do
   it "should find all of the solutions owned by a user" do
     Solution.should_receive(:find_by_user_id).with(@user.id).and_return(@solutions)
     get :index, :id => @user.id
   end
 end
end

However, this gets me the following error:

ActionController::RoutingError in 'SolutionsController GET index should find all of the solutions owned by a user'
No route matches {:id=>nil, :controller=>"solutions", :action=>"index"}

Can anybody point me to how I can test this, since the index should always be called within the scope of a particular user?

Factory#build 构建该类的实例，但不保存它，因此它还没有 id。

因此，@user.id 为零，因为 @user 尚未保存。

由于 @user.id 为零，因此您的路线未激活。

尝试使用 Factory#create 代替。

  before(:each) do
    @user = Factory.create(:user)
    @solution = Factory.create(:solution, :user => @user)
  end

Factory#build builds an instance of the class, but doesn't save it, so it doesn't have an id yet.

So, @user.id is nil because @user has not been saved.

Because @user.id is nil, your route isn't activated.

try using Factory#create instead.

  before(:each) do
    @user = Factory.create(:user)
    @solution = Factory.create(:solution, :user => @user)
  end

看起来您的另一个问题就在这一行：

 get :index, :id => @user.id

您正在尝试向索引方法发出请求，但您提供了错误的变量名称。当测试 SolutionsController id 暗示解决方案 ID 时，您需要提供用户 ID。这应该有效，或者至少可以推动你前进：

 get :index, :user_id => @user.id

Looks like your other problem is on this line:

 get :index, :id => @user.id

You're trying to make a request to the index method, but you've provided the wrong variable name. When testing SolutionsController id implies a solution id, you need to supply the user id. This should work, or at least move you forward:
