我是rails新手，并试图帮助解决问题。Ruby中的自定义路由
我需要为访客用户设置一个自定义路由，以查看来自特定子域的公共内容。即当访客用户转到subdomain.myapp.com时，他们将看到访客内容，如果他们登录，他们将看到特定于其角色的内容并添加内容。所以，我已经建立了以下路线：
match '/', to: "lessons#custom", constraints: { subdomain: 'hbec2' }, via: [:get]
match '/', to: 'home#index', constraints: { subdomain: 'www' }, via: [:get]
root :to => "home#index"
get "welcome" => "lessons#welcome", :as => "welcome"
constraints subdomain: 'hbec2' do
resources :home do
collection do
get '/lessons/:lesson_category_id', to: 'lessons#custom', as: 'lessons'
get "custom"
get "load_categories"
get "load_subcategories"
get "load_child_subcategories"
end
end
end
constraints subdomain: 'www' do
resources :home do
collection do
get "sub_categories"
get "categories" => "lessons#welcome"
get "welcome"
end
end
end
目前，当用户去hbec2.myapp.com他们得到期望的结果，因为它的路线是在我的教训控制器我的自定义功能，使我的自定义.html.erb。但是，当他们点击自定义视图中的链接时，它们将被重定向到index.html.erb而不是保留在该视图上，该视图具有部分html来呈现结果。
我所希望的是他们会留在custom.html.erb中，所以我添加了额外的资源获得'/ lessons /：lesson_category_id'，以：'lessons＃custom'，如：'lessons'希望是它会寻找的。但没有运气。这里是我的自定义功能从控制器和自定义视图
自定义功能（这个想法是为来宾用户提供信息。来宾用户属于HBEC组织，因此他们登录到hbec.myapp.com并获得正确的结果（hbec的类别列表和hbec最近的课程列表），当单击课程类别时，应该向他们显示该类别中的课程（查询返回正确的结果，因为课程是最近的，当您单击类别它说什么也没有），而是显示他们什么都没有。因为它去，而不是停留在custom.html.erb
