ruby-on-rails - Rails 4 - 从/user/:id to/:username 更改 URL

Question

我有一个 Controller pages#dashboard，我已将其设置为 routes.rb 中的 user_root

devise_for :users, controllers: { registrations: 'registrations' }
devise_scope :user do
  get "/signup" => "devise/registrations#new"
  get "/login" => "devise/sessions#new"
  get "/logout" => "devise/sessions#destroy"
  get "/:id" => "users#dashboard", :as => "user_root", :id => :username
end

我希望 URL 为 http://my_app.com/current_user_username

我已将 user.rb 模型中的 to_param 设置为:

def to_param
  username
end

当我有一个链接时，这工作正常:

<%= link_to "MY ACCOUNT", user_root_path(current_user) %>

但在初始登录时，URL 是:http://my_app.com/username (明确地说“用户名”)而不是 http://my_app.com/current_user_username

我尝试将 to_param 设置为:

def to_param
  "#{username}"
end    

并且还尝试将我的 route.rb 设置为:

get "/:id" => "users#dashboard", :as => "user_root", :id => :username, :via => :get

这些都没有解决问题。

环境:Rails 4.2.5、Ruby 2.3.0、Devise gem 3.5.3

如有任何帮助，我们将不胜感激。

Answer 1

您可以简单地在 routes.rb 中的所有内容之上添加另一条路线:

get "/:username" => "users#dashboard", :as => "user_root"
devise_for :users, controllers: { registrations: 'registrations' }
devise_scope :user do
  get "/signup" => "devise/registrations#new"
  get "/login" => "devise/sessions#new"
  get "/logout" => "devise/sessions#destroy"
  get "/:id" => "users#dashboard", :as => "user_root", :id => :username
end

然后你需要通过这样的方式找到用户:

    @user = User.find_by(username: params[:username])
