How to use subfolder inside views with Ruby on Rails
问题
我遇到了这个错误：
uninitialized constant DogsBreeds
每次我尝试访问：animals.com/doberman
这是我的home_controller.rb：
class HomeController < ApplicationController
def page1
end
def page2
end
end
这是我的routes.rb：
scope module: "dogs_breeds" do
get "/doberman", to: 'home#page1'
get "/chihuahua", to: 'home#page2'
end
而我的视图文件夹组织如下：
views > home > dogs_breeds > page1.html.erb
我尝试创建了dogs_breeds_controller.rb，如下所示：
class DogsBreedsController < ApplicationController
def page1
end
def page2
end
end
但是仍然没有改变。
英文:
Im having this error:
`uninitialized constant DogsBreeds`
Everytime I try to access to: animals.com/doberman
This is my home_controller.rb:
class HomeController < ApplicationController
def page1
end
def page2
end
end
This is my routes.rb
scope module: "dogs_breeds" do
get "/doberman", to: 'home#page1'
get "/chihuahua", to: 'home#page2'
end
And my views folder is organized like this:
views > home > dogs_breeds > page1.html.erb
I have tryed to create the dogs_breeds_controller.rb
class DogBreedsController < ApplicationController
def page1
end
def page2
end
end
But nothing has changed.

在定义你的路由时，像这样：
scope module: "dogs_breeds" do
get "/doberman", to: 'home#page1'
get "/chihuahua", to: 'home#page2'
end
然后，Ruby on Rails 的命名约定要求你有一个名为 HomeController 的控制器，命名空间为 DogBreeds，并且放置在一个名为 dog_breeds 的子文件夹中，就像这样：
# 在 app/controllers/dogs_breeds/home_controller.rb 中
module DogBreeds
class HomeController < ApplicationController
def page1
#...
end
def home2
#...
end
end
end
请参考官方 Rails 指南中的 Rails Routing from the Outside In。
英文:
When defining your routes, like this
scope module: "dogs_breeds" do
get "/doberman", to: 'home#page1'
get "/chihuahua", to: 'home#page2'
end
then Ruby on Rails' naming conventions expect you to have a HomeController controller namespaced with DogBreeds and placed in a dog_breeds subfolder like this:
# in app/controllers/dogs_breeds/home_controller.rb
module DogBreeds
class HomeController < ApplicationController
def page1
#...
end
def home2
#...
end
end
end
