Question

所以我一直在关注Dakota Lee Martinez Appointment项目，试图让它适应我的项目（我的项目是预订系统，为客户预约。我一直试图让我的约会显示在日历上就像在他的日历上一样，但是我对我应该怎么样感到有些困惑。我已经多次尝试但是一直在犯错误。

（使用gem＆＃34; simple_calendar＆＃34;，＆＃34;〜＆gt; 2.0＆＃34;显示日历）

错误：

NoMethodError in AppointmentsController#index

undefined method `upcoming_appointments' for nil:NilClass
Rails.root: C:/Sites/booking_saloniser - Calendar

有没有人有机会帮助我如何做达科塔在他的项目上所做的事情？我尝试过搜索不同的宝石等来帮助我这样做，但我喜欢Dakota所做的事情。
