Rails 5.1 测试更改的属性 弃用警告

Question

我刚刚将我的 5.0.1 应用升级到 5.1，每当我运行我的 rspec 测试时，我都会收到大量的警告。

DEPRECATION WARNING: ActiveSupport.halt_callback_chains_on_return_false= is deprecated and will be removed in Rails 5.2. (called from <top (required)> at /home/doomy/Documents/rsm/config/initializers/new_framework_defaults.rb:23)
...DEPRECATION WARNING: The behavior of `changed_attributes` inside of after callbacks will be changing in the next version of Rails. The new return value will reflect the behavior of calling the method after `save` returned (e.g. the opposite of what it returns now). To maintain the current behavior, use `saved_changes.transform_values(&:first)` instead. (called from block (3 levels) in <top (required)> at /home/doomy/Documents/rsm/spec/controllers/products_spec.rb:48)

这对于我进行的每一项测试都会进行，并且最终花费了相当长的时间，因为它要编写很多东西来控制台。

我对我应该改变什么感到很困惑，因为有问题的代码看起来并没有什么不寻常的地方。

这是第 48 行附近的 products_spec.rb

describe "GET show" do

before(:each) do
  @product = create(:product, user: create(:product_admin))
end

context "anonymously" do
  it "renders" do
    get :show, params: { id: @product.id }
    expect(response).to render_template("show")
  end
end

context "as regular user" do
  it "renders" do
    get :show, params: { id: @product.id }
    login(create(:user))
    expect(response).to render_template("show")
  end
end
...

我认为它必须与 before 过滤器有关，但我不太清楚是什么。搜索警告不会返回任何有用的信息。

谢谢。
