Question

我的模型中定义了以下搜索功能：

class CoffeeType < ActiveRecord::Base
  has_many :coffee_items

   def self.search(search)
    if search
      where('name LIKE ?', "%#{search}")
    else
      where(nil)
    end
  end 
end

并进行以下RSpec测试：

 describe "GET index with serach params" do
       it 'renders a list of Coffee Types' do
         get :index, {search: "Ame"}, valid_session
         assigns(:coffee_types).count.should eq(2)
       end
    end

这可能非常微不足道，我在这里看不到更大的图景。

有关默认rspec use_transactional_fixtures设置的说明，请参阅此处：

除非您更改了此配置，否则在每个示例后都会重置数据库。因此，您需要在示例/示例组中实际设置初始状态。在您的情况下，可能看起来像：

describe "GET index with serach params" do
  before :each do
    # create two coffee_types that should be found by searching for "Ame" and
    # one that shouldn't
    2.times { FactoryGirl.create :coffee_type }
    FactoryGirl.create :coffee_type, name: "Espresso" 
  end  

  it 'renders a list of Coffee Types' do
    get :index, {search: "Ame"}, valid_session
    assigns(:coffee_types).count.should eq(2)
  end
end

编辑：Duh！实际上，模型方法中的代码不正确。在搜索字词之前，您只获得了%通配符。将该行更改为：

where('name LIKE ?', "%#{search}%")

正确的方法通过params指数Rspec测试
