我正在学习Rails以及如何使用RSpec进行测试。我需要帮助完成PUT更新操作的RSpec控制器测试。该控制器指向一个嵌套资源。在Web浏览器中,嵌套路由和相关程序代码都能正常工作。我只需要帮忙编写PUT更新操作的RSpec测试。控制器执行的其他操作已经通过测试。
我知道必须传递路径和父子ID给PUT方法,但我对以下内容感到困惑:(1)如何使用FactoryGirl对象正确设置PUT更新测试,以及(2)传递路径和ID到PUT方法中所需的正确RSpec语法。
rake routes中的相关路由:
请查看我的测试设置和PUT更新测试。特别是,我的设置是否正确测试PUT更新操作?
如何更改控制器的更新操作的设置和/或测试,以便:
(1) 我的测试与我的更新操作的路由匹配?
(2) 我以正确的RSpec语法传递必要的父级和子级ID,以便找到记录?
感谢您的帮助!
我知道必须传递路径和父子ID给PUT方法,但我对以下内容感到困惑:(1)如何使用FactoryGirl对象正确设置PUT更新测试,以及(2)传递路径和ID到PUT方法中所需的正确RSpec语法。
rake routes中的相关路由:
PATCH /members/:member_id/cardio_exercises/:id(.:format) cardio_exercises#update
PUT /members/:member_id/cardio_exercises/:id(.:format) cardio_exercises#update
routes.rb 中包含: resources :members do resources :cardio_exercises end
members.rb 中包含: has_many :cardio_exercises, :dependent => :destroy
cardio_exercises.rb 中包含: belongs_to :member
相关工厂:
FactoryGirl.define do
factory :cardio_exercise do
title "My cardio exercise"
duration 30
calories_burned 300
date "2014-11-15"
association :member
end
end
FactoryGirl.define do
factory :member do
first_name {Faker::Name.first_name}
last_name {Faker::Name.last_name}
age 21
height 75
weight 195
goal "fffff" * 5
start_date "2014-11-15"

cardio_exercises_controller.rb文件

请查看我的测试设置和PUT更新测试。特别是,我的设置是否正确测试PUT更新操作?
如何更改控制器的更新操作的设置和/或测试,以便:
(1) 我的测试与我的更新操作的路由匹配?
(2) 我以正确的RSpec语法传递必要的父级和子级ID,以便找到记录?
