我在我的应用程序中有一个计划模型。有时我遇到以下错误。重新启动服务器后,它会消失一段时间。PayPal-Ruby-SDK模型名称冲突
宝石版本(1.6.0)
如何修复?
NoMethodError in Subscriptions#index

您能否给我们实施您的计划对象? – romainsalles
@romainsalles它只有2行'has_many:subscriptions'和 'has_many:users,through::subscriptions'。这不是关于包含枚举,因为它在重新启动服务器后工作正常。 – kirqe
我不知道PayPal宝石。但看看文档,我认为你应该尝试调用'Plan.all.members'或'Plan.all.to_hash'并看看你在那里得到了什么。因为'Plan.all'不返回一个数组而是一个'PlanList'对象(@see:https://github.com/paypal/PayPal-Ruby-SDK/blob/master/lib/paypal-sdk/rest /data_types.rb#L2055) – romainsalles
