ActionController::Routing 错误（嵌套资源 - Rails 4 Ruby 2）
ActionController::Routing Error (Nested Resources - Rails 4 Ruby 2)
我正在尝试嵌套资源，以避免嵌套资源 3 深。
我最初的计划是做这样的事情：（这样你就可以看到我的思考过程）
resources :properties do
resources :stalls do
resources :bookings
end
end
end
我最后做的是这样的：
## Nested Relationship for Proerty / Stall ##
resources :properties do
resources :stalls, except: [:index], controller: 'properties/stalls'
end
## END Nested Relationship for Property / Stall ##
## Nested Relationship for Stall / Bookiing ##
resources :stalls do
resources :bookings, except: [:index], controller: 'stalls/bookings'
end
## END Nested Relationship for Stall / Bookiing ##
在我提交预订表格之前，一切都在进行中。即使在那个时候它确实提交了预订并创建了记录，但没有重定向回 stalls/1。
服务器错误为：
