如何为表单确认页面定义自定义URL？ [英] How do I define a custom URL for a form confirmation page?

问题描述

我正在用Rails创建一个基本的产品登录页面，用户可以在其中输入其电子邮件地址，以在产品启动时得到通知。 （是的，有一些服务/宝石等可以为我做这件事，但是我是编程新手，想自己构建它以学习Rails。）

I am creating a basic product landing page with Rails in which users can enter their email address to be notified when the product launches. (Yes, there are services/gems etc that could do this for me, but I am new to programming and want to build it myself to learn rails.)

成功提交表单后，我想重定向到一个自定义的 /谢谢页面，在该页面中，我感谢用户对产品的关注（并鼓励他们完成简短的调查。）

On successful submit of the form, I would like to redirect to a custom '/thanks' page in which I thank users for their interest in the product (and also encourage them to complete a short survey.)

当前，成功提交的信息显示在 / invites /：id /，例如 invites / 3，我不希望看到它，因为它公开了已提交的邀请数量。我想将所有成功的提交重定向到 /谢谢页面。

Currently, successful submits are displayed at "/invites/:id/" eg "invites/3" which I do not want since it exposes the number of invites that have been submitted. I would like to instead redirect all successful submits to a "/thanks" page.

我试图研究 rails custom URLs，但是却找不到任何东西那个有效。我能找到的最接近的是该 Stackoverflow帖子，如何使用自定义路由重定向，但并未完全了解建议的解决方案。我也尝试阅读路线指南，但是对此并不陌生，什么也没看到我理解允许创建自定义URL。

I have attempted to research "rails custom URLs" but have not been able to find anything that works. The closest I was able to find was this Stackoverflow post on how to redirect with custom routes but did not fully understand the solution being recommended. I have also tried reading the Rails Guide on Routes but am new to this and did not see anything that I understood to allow for creating a custom URL.

我已将我要表示感谢信息的消息显示在 views / invites / show.html提交的成功表单中。 .haml

I have placed my thanks message which I would like displayed on successful form submit in "views/invites/show.html.haml"

我的路线文件

resources :invites
root :to => 'invites#new'

我尝试在route.rb中插入：

I tried inserting in routes.rb:

post "/:thanks" => "invites#show", :as => :thanks

但是我不知道这是否可行或如何告诉控制器重定向到：谢谢

But I don't know if this would work or how I would tell the controller to redirect to :thanks

我的控制器（基本上是香草导轨，此处仅包括相关操作）：

My controller (basically vanilla rails, only relevant actions included here):

def show
    @invite = Invite.find(params[:id])
    show_path = "/thanks"

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @invite }
    end
  end

# GET /invites/new
# GET /invites/new.json
def new
  @invite = Invite.new

  respond_to do |format|
    format.html # new.html.erb
    format.json { render json: @invite }
  end
 end

 # POST /invites
 # POST /invites.json
 def create
   @invite = Invite.new(params[:invite])

   respond_to do |format|
     if @invite.save
       format.html { redirect_to @invite }
       #format.js { render :action => 'create_success' }
       format.json { render json: @invite, status: :created, location: @invite }
     else
       format.html { render action: "new" }
       #format.js { render :action => 'create_fail' }
       format.json { render json: @invite.errors, status: :unprocessable_entity }
     end
   end
 end

似乎创建用于显示确认的标准URL相对简单。

It would seem as if creating a standard URL for displaying a confirmation would be relatively straightforward. Any advice on how to achieve this would be appreciated.

推荐答案

我想您想在执行create操作后重定向。

I guess you want to redirect after your create action, which is executed when the form is submitted.

只需按以下方式添加redirect_to：

Just add redirect_to in the following way:

def create
  @invite = Invite.new(params[:invite])

  if @invite.save
    ...
    redirect_to '/thanks'
  else
    ...
    redirect_to new_invite_path # if you want to return to the form submission page on error
  end
end

为简洁起见，我省略了一些代码。

I omitted some of the code for brevity.

在您的路线中添加：

get '/thanks', to: "invites#thanks"

向您的邀请控制器添加感谢动作：

Add the thanks action to your invites controller:

def thanks
  # something here if needed
end

并创建thank.html应用/视图/邀请中的.erb页面。

And create a thanks.html.erb page in app/views/invites.
