我使用了Devise 3.0，一切都还可以，但是因为我使用Devise 3.2.4我的路线问题很多......
使用Devise 3.0，此代码有效：
devise_for :users,
:controllers => { :registrations => "users/registrations",
:passwords => "users/passwords",
:sessions => 'users/sessions'},
:skip => [:sessions] do
get 'identification' => 'users/sessions#new', :as => :new_user_session
post 'identification' => 'users/sessions#create', :as => :user_session
get 'deconnexion' => 'users/sessions#destroy', :as => :destroy_user_session
get 'inscription' => 'users/registrations#new', :as => :new_user_registration
get 'mot-de-passe' => "users/passwords#new", :as => :new_password_user
get 'mon-compte' => "users/registrations#edit", :as => :edit_user_registration
end
devise_scope :user do
get "users/pdf", :controller => "users/registrations", :action => "pdf"
get "users/download_pdf", :controller => "users/registrations", :action => "download_pdf"
get "informations-personnelles", :controller => "users/registrations", :action => "edit_profile0", :as => "users_edit_profile0"
get "vous-et-votre-projet", :controller => "users/registrations", :action => "edit_profile1", :as => "users_edit_profile1"
get "caracteristiques-du-bien", :controller => "users/registrations", :action => "edit_profile2", :as => "users_edit_profile2"
get "details-du-bien", :controller => "users/registrations", :action => "edit_profile3", :as => "users_edit_profile3"
get "quartier", :controller => "users/registrations", :action => "edit_profile4", :as => "users_edit_profile4"
get "lieu", :controller => "users/registrations", :action => "edit_profile5", :as => "users_edit_profile5"
get "budget", :controller => "users/registrations", :action => "edit_profile6", :as => "users_edit_profile6"
get "coup-de-coeur", :controller => "users/registrations", :action => "edit_profile7", :as => "users_edit_profile7"
put "users/update_avatar", :controller => "users/registrations", :action => "update_avatar"
put "users/update_profile0", :controller => "users/registrations", :action => "update_profile0"
put "users/update_profile1", :controller => "users/registrations", :action => "update_profile1"
put "users/update_profile2", :controller => "users/registrations", :action => "update_profile2"
put "users/update_profile3", :controller => "users/registrations", :action => "update_profile3"
put "users/update_profile4", :controller => "users/registrations", :action => "update_profile4"
put "users/update_profile5", :controller => "users/registrations", :action => "update_profile5"
put "users/update_profile6", :controller => "users/registrations", :action => "update_profile6"
put "users/update_profile7", :controller => "users/registrations", :action => "update_profile7"
get "users/heating", :controller => "users/registrations", :action => "heating", :as => :heating
get "users/water_heater", :controller => "users/registrations", :action => "water_heater", :as => :water_heater
end
end
由于我使用Devise 3.2.4，我遇到了一些问题：
undefined local variable or method `destroy_user_session_path'
或者
undefined local variable or method `new_user_session_path'
我在这个问题上工作了几个小时，但我找不到好的解决方案......

有人可以帮助我吗？
答案 0 :(得分：2)
在较新版本的devise_for中不推荐将该块传递给Devise。这就是您在块中传递给devise_for的路由被完全忽略的原因。您可以在rake routes结果中注意到这一点，这些路线无处可见。
由于路线本身不存在，因此您在访问destroy_user_session_path或new_user_session_path时会收到错误。
要解决此问题，您需要在devise_scope中添加这些路线：
## You need to skip `:registrations` and `:passwords` routes too because you are resetting them as well
devise_for :users,
:controllers => { :registrations => "users/registrations",
:passwords => "users/passwords",
:sessions => 'users/sessions'},
:skip => [:sessions, :registrations, :passwords]
devise_scope :user do
get 'identification' => 'users/sessions#new', :as => :new_user_session
post 'identification' => 'users/sessions#create', :as => :user_session
get 'deconnexion' => 'users/sessions#destroy', :as => :destroy_user_session
get 'inscription' => 'users/registrations#new', :as => :new_user_registration
get 'mot-de-passe' => "users/passwords#new", :as => :new_password_user
get 'mon-compte' => "users/registrations#edit", :as => :edit_user_registration
## Rest of the routes
end
