我正在尝试运行测试以渲染模板并遇到错误:
undefined method `key?' for 1014:Fixnum
我的模型实例的存根在我的路由测试中应该正常工作,但在这里没有那么多。我做错了什么?
describe RestaurantsController do
let(:restaurant) { FactoryGirl.build_stubbed(:restaurant) }
describe 'GET #show' do
before { get :show, restaurant.id }
it { should render_template('show') }
end
end
完整错误
1) RestaurantsController GET #show
Failure/Error: before { get :show, restaurant.id }
NoMethodError:

答案 0 :(得分:2)
get
采取行动和参数的散列(除其他外)。它不会隐含地采用模型并将其转换为{ id: model.to_param }
。
相反,您需要明确指定参数。
describe RestaurantsController do
let(:restaurant) { create(:restaurant) }
subject { response }
describe 'GET #show' do
before { get :show, id: restaurant }
it { should render_template('show') }
end
end
正如@Зелёный已经提到过,您需要将记录实际保存到数据库中才能在控制器规范中使用它。
为避免重复问题和测试排序问题,您应在每个示例之间清空数据库。 database_cleaner gem对于该任务非常宝贵。
此外,如果您需要在同一规范中创建多个记录,则可以使用工厂女孩中的序列:
FactoryGirl.define do
factory :user do
email { |n| "test-#{n}@example.com" }
end
end
gem ffaker非常适合生成电子邮件,用户名等。
您可以通过在rails_helper
:
RSpec.configure do |config|
# ...
config.include FactoryGirl::Syntax::Methods
end
这使您可以使用FactoryGirl方法而无需输入模块名称,如下所示:
let(:restaurant) { create(:restaurant) }
