控制器规格未知关键字：id

Question

我有简单的动作表演

def show
  @field = Field.find_by(params[:id])
end

我想为它编写规范

require 'spec_helper'

RSpec.describe FieldsController, type: :controller do

    let(:field) { create(:field) }

  it 'should show field' do
    get :show, id: field
    expect(response.status).to eq(200)
  end
end

但是我有一个错误

Failure/Error: get :show, id: field

 ArgumentError:
   unknown keyword: id

如何解决？

Answer 1

HTTP request methods will accept only the following keyword arguments params, headers, env, xhr, format

根据新的 API，您应该使用关键字参数，params 在这种情况下：

  it 'should show field' do
    get :show, params: { id: field.id }
    expect(response.status).to eq(200)
  end

控制器规格未知关键字：id

Controller spec unknown keyword: id
