Question

我最近将远程数据库连接到我网站的生产版本。但是，现在我的路线不起作用了。

在我的Heroku日志中，我的应用正在寻找Parameters: {"id"=>"edit"}.

但我的数据库中没有：id参数。指定的唯一索引是 order_id 。

如何编辑 routes.db ，以便在我的路径中使用 order_id ？这是甚至是必要的还是还有其他我应该看的东西？

本地数据库中的列列表：

1.9.3-p392 :001 > Order.column_names
 => ["order_id", "product_status", "img_reference", "img_source", "user_email", "user_name", "user_address", "user_city", "user_zipcode", "user_state", "product_size", "product_type", "payment_id", "image_file_name", "image_content_type", "image_file_size", "image_updated_at"]

远程数据库中的列列表：

irb(main):001:0> Order.column_names
=> ["order_id", "order_date", "product_status", "img_reference", "img_source", "user_email", "user_name", "user_address", "user_city", "user_zipcode", "user_state", "product_size", "product_type", "uservendor_id", "paypal_confirmation"]

同样，我的路线似乎在我的开发版本中运行良好。

我能想到的唯一区别是我的远程数据库中有一些额外的列，我认为这些列不会影响路径。

这是我在Heroku日志中遇到的错误：

Answer 1

因此，在ActiveRecord中，如果您有自定义主键，则需要在模型中指定它

class Order
  self.primary_key = :order_id

文档：http://guides.rubyonrails.org/active_record_basics.html#overriding-the-naming-conventions

生产中的Rails路由正在寻找param：id。如何告诉它使用：order_id？
