Rails渲染路线路径 [英] Rails render route path

问题描述

我对Rails还是陌生的，并且很难理解路径系统在Rails中的工作方式。

Im still new to Rails and have a hard time understanding how the path system works in Rails.

在我的route.rb中，我为注册创建了别名：

In my routes.rb i create an alias for signup:

match 'signup' => 'user#new'
resource :user, :controller => 'user'

操作在那里，转到/ signup会显示正确的操作。到目前为止，一切都很好。

The action is there and going to /signup shows the correct action. So far so good.

现在，当我提交我的注册表单时，它会像往常一样使用POST运行create操作。这就是即时通讯卡住的地方。

Now, when i submit my signup form it runs the create action with POST as usual. And here is where im stuck.

如果注册失败，我想再次向用户提供注册表单。一种选择是进行新渲染，但这会将用户带到/ user而不是/ signup。

If the signup fails, i would like to present the user with the signup form again. One option would be to do a render "new", but that takes the user to /user instead of /signup.

UserController

class UserController < ApplicationController

  def new
    @user = User.new
  end


  def create

    @user = User.new(params[:user])

    if @user.save
      redirect_to root_url
    else
      render "new"
    end

  end

end

任何帮助表示赞赏！

更新-解决方案

为/ signup添加了2个匹配路由，使用：via option

Added 2 match routings for /signup, using the :via option

match 'signup' => 'user#new', :as => :signup, :via => 'get'
match 'signup' => 'user#create', :as => :signup, :via => 'post'

通过这种方式，应用程序知道在发布到/ signup时应运行create动作，

This way the application knows that when posting to /signup it should run the create action, and when http method is get, it uses the new action.

控制器标记与上面发布的相同。

Controller markup is the same as posted above.

推荐答案

尝试在路由中添加 ：as ：

match 'signup' => 'user#new', :as => :signup

然后执行

redirect_to signup_url

在您的控制器中。

对我有用。我仍然不知道为什么。也许其他人有解释。

That worked for me. I still don't know why. Maybe someone else has an explanation.
