如何期待Rails 5中RSpec中的Params散列？

我正在升級到Rails 5，這已經打破了我的RSpec，即使我傳遞了我應該的數據。如何期待Rails 5中RSpec中的Params散列？

顯然，問題在這裏：

expected: ({"name"=>"MyString"}) 
got: (<ActionController::Parameters {"name"=>"MyString"} permitted: true>)

這意味着我需要能夠解決我的控制器斷言，這樣，預計後者。這是需要改變的路線。

expect_any_instance_of(Hospital).to receive(:update).with({ "name" => "MyString" })

大概是這樣的

expect_any_instance_of(Hospital).to receive(:update).with(params: { "name" => "MyString" }, permitted: true)

我只是不知道語法是什麼，並不能找到它散落文檔中的任何地方爲Rails 5，或不存在票據/ on Rails的有關RSpec的堆棧溢出問題5.

     put :update, {:id => hospital.to_param, :hospital => { "name" => "MyString" }}, valid_session

您是否嘗試過使用ActionController :: Parameters對象作爲您期望的值？

如：

expect_any_instance_of(Hospital).to receive(:update).with(ActionController::Parameters.new('name':'MyString'))

泰非常多，不知道你可以只調用了這樣的一些參數。這裏是什麼工作，請注意在最後包含許可 - 'expect_any_instance_of（Hospital）.to接收（：update）.with（ActionController :: Parameters.new（'name'：'MyString'）。permit（：name））' – user2792268
