rails4 将默认 url xxx.com/new_page 更改为 xxx.com/new_page/username

Question

我用rails4.2.8和ruby2.5.0，在注册新用户的时候，我设置新页面跳转到http://127.0.0.1:3000/email_confirm，但是现在我想把url改成http://127.0.0.1:3000/email_confirm/username，也就是我要加@ 987654325@ 到默认网址，我该如何重写代码？非常感谢您的帮助~~

controllers/user_controller.rb 代码如下：

def create
    @user = User.new(user_params)  
    if @user.save
      log_in @user
      flash[:success] = "almost success!"
      redirect_to :email_confirm
    else
      flash.now[:danger] = 'fail to signup！'
      render :new
    end
  end

  def show
    @user = User.find(params[:id])
  end

routes.rb 代码如下：

get 'signup'  => 'users#new'
get 'login'   => 'sessions#new'
get 'profile' => 'users/show'
get 'email_confirm' => 'users#email_confirm'
post 'login'   => 'sessions#create'
delete 'logout'  => 'sessions#destroy'
resources :users

和email_confirm.html.erb 中的app/views/users/email_confirm.html.erb

在您的routes.rb 中，更改：

get 'email_confirm' => 'users#email_confirm'

到：

get 'email_confirm/:username' => 'users#email_confirm', as: 'confirmation'

那么，一旦用户注册成功，redirect_to confirmation_path(@user.username)
