设计命名空间 - ActionController :: RoutingError（无路由匹配{：action =>“new”，：controller =>“devise / sessions”}）

Question

I'm using Devise and everything has been working great, but I am now trying to move things into an 'admin' namespace.

I have a route that looks like:

namespace :admin do
  devise_for :users, :controllers => { :registrations => "admin/users/registrations" }
end

In one of my controllers I have

before_filter :authenticate_user!

but when that gets called it throws:

ActionController::RoutingError (No route matches {:action=>"new", :controller=>"devise/sessions"}): 

Any ideas?

Answer 1

As per the Devise documentation (which likely has changed since this posting), you could use the following instructions:

#    ...
#    
#    Notice that whenever you use namespace in the router DSL, it automatically sets the module.
#    So the following setup:
#
#      namespace :publisher do
#        devise_for :account
#      end
#
#    Will use publisher/sessions controller instead of devise/sessions controller. You can revert
#    this by providing the :module option to devise_for.
#    
#    ...

Hope this helps someone.

I'm doing this:

scope '/admin' do
  devise_for :admins
end

Answer 3

A workaround for this is to use the path option and move devise_for outside of the namespace block:

devise_for :users, :path => '/admin',
                   :controllers => { :registrations => "admin/users/registrations" }
namespace :admin do
  # other resource controllers
end

Perhaps it's not as elegant (or intuitive), but it works for me!
