Rails3邀请函和邮件程序 - 如何向路径/网址添加变量？ [英] Rails3 invitations and mailer - how to add variables to routes/urls?

问题描述

这应该是简单的修复，但是我一直找不到答案。任何人都可以指向正确的方向？

This should be simple fix, but I've been unable to find an answer. Can anyone point me in the right direction?

我正在实施一个Rails3测试版邀请系统，一个Ryan Bates - http://railscasts.com/episodes/124-beta-invitations

I'm implementing a Rails3 beta invite system a la Ryan Bates - http://railscasts.com/episodes/124-beta-invitations

I我设置了邮件发送邀请URL。一切都很好，除了一个小问题。

I've set up the mailer to send out the invite urls. Everything works fine, apart from one small issue.

邮件程序生成的网址是/user/sign_up.token。

The url generated by the mailer is /user/sign_up.token.

我需要生成/ user / sign_up / token（斜线而不是句点）。

I need to generate /user/sign_up/token (slash instead of period).

我想我需要更改Mailer.invitation（）。deliver中的语法，但是我找不到任何文档可以帮助。任何人都可以指向正确的方向？

I guess I need to change the syntax in "Mailer.invitation().deliver", but I can't find any documentation to help. Can anyone point me in the right direction?

我的路线文件的相关位：

The relevant bits of my routes file:

devise_for :users,  :path_prefix => 'registration', :controllers => {:registrations => 'users/registrations'} do
    get   "registration/users/sign_up/:invitation_token" => "users/registrations#new"
end

邀请控制器：

class InvitationsController < ApplicationController
  def new
    @invitation = Invitation.new
    @title = "Invite a friend"
  end

  def create
    @invitation = Invitation.new(params[:invitation])
    @invitation.sender = current_user
    if @invitation.save
        if user_signed_in?
            Mailer.invitation(@invitation, new_user_registration_path(@invitation.token)).deliver
            redirect_to root_url, :notice => "Thank you, your friend will receive their invitation soon."
        else
            redirect_to root_url, :notice => "Thank you, we'll let you know when the next batch of invites are availale."
        end
    else
        if current_user.invitation_limit > 0
            render :action => 'new', :alert => "Sorry, there was a problem! Please try a again."
        else
            redirect_to root_url, :alert => "Sorry, you don't have any invitations left. Please wait until we issue more."
        end

    end
  end
end

Mailer：

class Mailer < ActionMailer::Base

  def invitation(invitation, sign_up)

    subject     'Invitation'
    recipients  invitation.recipient_email
    @greeting = "Hi"
    @invitation = invitation
    @signup_url = sign_up
    @sender = invitation.sender_id
    invitation.update_attribute(:send_at, Time.now)       
  end
end

感谢您的任何想法！

推荐答案

不完全确定这是否可以工作，但也可以尝试

Not completely sure if this would work, but maybe try

new_user_registration_url(@invitation.token)

而不是new_user_registration_path。

instead of new_user_registration_path.

另一个（但不是很好）的方法将是

Another (but not a very good) method would be

new_user_registration_url+"/#{@invitation.token}" #substitute path for url maybe
