我目前在我的rails应用中使用Devise。我想用我的api添加Devise Token Auth进行身份验证。当我尝试使用
设置devise_token_auth时rails g devise_token_auth:install User auth
rake db:migrate
我收到以下错误：
~/workspace (devise_token_auth) $ rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
ArgumentError: Invalid route name, already in use: 'new_user_session'
You may have defined two routes with the same name using the `:as` option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with `resources` as explained here:

我理解这是因为路线上的冲突。 我如何让它工作？ 有没有解决办法？
答案 0 :(得分：6)
为了使用devise_token_auth和devise，我们需要在devise_token_auth初始化程序中设置一个标志，如下所示：
DeviseTokenAuth.setup do |config|
# enable_standard_devise_support = false
end
和路径文件也需要更改
Rails.application.routes.draw do
# standard devise routes available at /users
# NOTE: make sure this comes first!!!
devise_for :users
# token auth routes available at /api/v1/auth
namespace :api do
scope :v1 do
mount_devise_token_auth_for 'User', at: 'auth'
end
end
end
