- 背景**
我正在学习一门过时的Ruby初学者课程，但是遇到了一些问题。在这门课程中，我正在构建一个类似于Yelp的Ruby on rails应用程序，它是用来列出和评论餐馆的。目前，我正在将评论链接到餐馆。我的Ruby版本是：ruby 3.0.0p0（2020年12月25日修订版本95aff21468）[x86_64-darwin22]我的rails版本是：Rails网站7.0.4.2
- 步骤**
我通过执行以下步骤将点评与餐厅联系起来：
- 运行
rails generate migration AddRestaurantIDToReviews restaurant_id:integer - 运行
rake db:migrate - 将
belongs_to :restaurant添加到reviews.rb - 将
has_many :reviews添加到restaurants.rb - 检查
rails routes - 调整后的
routes.rb文件 - 调整后
reviews_form.html.erb - 调整后的
review_controller.rb文件 - 操作前
set_restaurant和set_restaurant - 为
restaurant_id添加@review语句（第...行） - 已删除指向旧URL的链接
- 重新启动服务器
- 错误信息**
这导致了以下错误：未定义#ActionView：：Base：0x0000000025800的方法"review_path"，这是由以下代码行触发的：〈%=带（型号：[@餐厅，@评论]，当地：真）做|形式|%〉（来自relevents_form. html. erb文件）.在this thread中解释了一个类似的问题，但我仍然无法理解它.
有人能帮我吗？如果你需要更多的信息，请让我知道!
