如何在 Rails 5 中期待 RSpec 中的 Params 散列？

Question

我正在升级到 Rails 5，尽管我正在传递我应该传递的数据，但它已经破坏了我的 RSpec。

显然问题出在这里：

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

这意味着我需要能够修复我的控制器断言，以便它期望后者。这是需要更改的行。

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，在 Rails 5 的零散文档中也找不到它，或者不存在 notes/Stack 有关 [=35= 的溢出问题] 在 Rails 5.

控制器规范方法

describe "PUT update" do
  describe "with valid params" do
    it "updates the requested hospital" do
      hospital = Hospital.create! valid_attributes
      # Assuming there are no other hospitals in the database, this
      # specifies that the Hospital created on the previous line
      # receives the :update_attributes message with whatever params are
      # submitted in the request.
      expect_any_instance_of(Hospital).to receive(:update).with({ "name" => "MyString" })
      put :update, {:id => hospital.to_param, :hospital => { "name" => "MyString" }}, valid_session
    end

    it "assigns the requested hospital as @hospital" do
      hospital = Hospital.create! valid_attributes
      put :update, {:id => hospital.to_param, :hospital => valid_attributes}, valid_session
      expect(assigns(:hospital)).to eq(hospital)
    end

    it "redirects to the hospital" do
      hospital = Hospital.create! valid_attributes
      put :update, {:id => hospital.to_param, :hospital => valid_attributes}, valid_session
      expect(response).to redirect_to(hospital)
    end
  end
...etc

您是否尝试过只使用 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'))
