如何期待Rails 5中RSpec中的Params散列？

我正在升级到Rails 5，这已经打破了我的RSpec，即使我传递了我应该的数据。如何期待Rails 5中RSpec中的Params散列？

显然，问题在这里：

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

这意味着我需要能够解决我的控制器断言，这样，预计后者。这是需要改变的路线。

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

大概是这样的

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

我只是不知道语法是什么，并不能找到它散落文档中的任何地方为Rails 5，或不存在票据/ on Rails的有关RSpec的堆栈溢出问题5.

您是否尝试过使用ActionController :: Parameters对象作为您期望的值？

如：

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

泰非常多，不知道你可以只调用了这样的一些参数。这里是什么工作，请注意在最后包含许可 - 'expect_any_instance_of（Hospital）.to接收（：update）.with（ActionController :: Parameters.new（'name'：'MyString'）。permit（：name））' – user2792268
