这个默认的 RSpec 语句是什么意思？
User.should_receive(:update_attributes).with({'these' => 'params'})
这句话是什么意思？ 这些没有在任何地方实例化为任何意义。
整个声明是这样的：
describe "with valid params" do
it "updates the requested user" do
User.should_receive(:find).with("37") { mock_user }
User.should_receive(:update_attributes).with({'these' => 'params'})
put :update, :id => "37", :user => {'these' => 'params'}
end
我这样说是因为我收到一个错误：
unknown attribute: these
这是来自上述场景的..
User.should_receive(:update_attributes).with({'these' => 'params'})
What does that statement mean? these isn't instantiated anywhere as meaning anything.
The whole statement is this :
describe "with valid params" do
it "updates the requested user" do
User.should_receive(:find).with("37") { mock_user }
User.should_receive(:update_attributes).with({'these' => 'params'})
put :update, :id => "37", :user => {'these' => 'params'}
end
I say this because I'm getting an error :
unknown attribute: these
Which is coming from aforementioned scenario..

也就是说，应该在
User模型上调用update_attributes方法，参数为{'these' =>; 'params'}在任何测试运行期间。基本上，在执行过程中预计会发生以下情况：

It is saying that the method
update_attributesshould be invoked on theUsermodel with an argument of{'these' => 'params'}during whatever test is being run.Basically the following is expected to happen during the execution:

您不必替换散列（{'这些' => 'params'}）。将其视为合同。我说过，当我 PUT 时，我的对象 update_attributes 模型应该接收以下哈希。在下一行中，您调用更新方法并检查合约。
You don't have to replace the hash ({'these' => 'params'}). Think of it as a contract. I have said that when I PUT, the following hash should be received by my objects update_attributes model. In the next line, you call the update method and the contract is checked.
