Ruby on rails - *** 运行时错误异常:ActionView::Helpers::ControllerH

Question

当我尝试为端点运行我的 api 规范时，我遇到了一个问题。当我运行规范并检查响应时，它说：

*** RuntimeError Exception: ActionView::Helpers::ControllerHelper#response delegated to controller.response, but controller is nil: #<RSpec::Core::ExampleGroup::Nested_1::Nested_1::Nested_1:0x007faeb4852b08

我在控制器/api/v1/catalog_controller.rb 下有一个控制器

class Api::V1::CatalogController < ApplicationController
  def search
    ...some stuff here...
    render json: {some_response}
  end
end

它的匹配规范在规范/控制器/api/v1/catalog_controller_spec.rb 下

describe Api::V1::CatalogController do
  describe "searching" do
    before(:all) do
      @title = FactoryGirl.create(:title, {name: "Test Title"})
      @author = FactoryGirl.create(:author, last_name: "Smith")
      @edition = FactoryGirl.create(:edition, title: @title, writer_id: @author.id)
    end
    context "#search" do
      it "should return the given titles for a single word search" do
        get :search, {search_terms: {term: 'smith'}}
        expect(response).status.to eql(200)
        return_value.body.should == {titles: [@title]}
      end
    end
  end
end

知道我可能做错了什么吗？

我已经通过删除该行解决了这个问题

 config.include ActionView::Helpers

从我的 spec_helper.rb 配置块。我想这是矛盾的。我不太确定为什么，所以任何进一步的见解都会很棒。
