ruby-on-rails - RSpec：带有 searchkick 的无效模型

问题描述

我不太确定我做得对，但我有两个模型：House那个has_one Address.

该Address模型具有：

class Address < ApplicationRecord
  searchkick
  belongs_to :house
end

我正在尝试house_controller像这样使用 RSpec测试我的

RSpec.describe HousesController do
 context 'GET #index' do
 before { get :index }
 it     { is_expected.to render_template('index') }

 it 'assigns @houses' do
  h = create(:house)
  expect(assigns(:houses).results).to eq([h])
end
...

尽管如此，我总是得到一个不是我期望的结果。我的控制器的代码如下：

def index
 if params[:term].present?
  @houses = House.search(params[:term])
 else
  @houses = House.search('*')
 end
end

我不确定我是否理解它，但可能是因为我使用FactoryBot它，它正在创建很多房子，然后当进入这个index方法时，那里有一堆房子，而且不仅而且准确h吗？

这是我的失败：

我现在从 RSpec 开始，尝试掌握它真的需要花费我的精力和时间，在此先感谢！

解决方案

尝试house在 before 块中创建您的：

context 'GET #index' do
  before do
    let!(:house) { create(:house) }
    get :index
  end

  it { is_expected.to render_template('index') }

  it 'assigns @houses' do
    expect(assigns(:houses).results).to eq([house])
  end
end

有几点需要注意：

  1. 与 , 相反let，let!立即调用（因此在点击索引操作之前创建您的记录）
  2. 添加断点 (IDE) 或使用调试器（byebug、pry 等）并将其放在get :index调用之前以查看哪些（如果有）房屋已经存在。
