在我的Rails应用程序中,我有一个Invite模型:
class Invite < ActiveRecord::Base
belongs_to :calendar
belongs_to :sender, :class_name => 'User'
belongs_to :recipient, :class_name => 'User'
before_create :generate_token
def generate_token
self.token = Digest::SHA1.hexdigest([self.calendar_id, self.recipient_role, Time.now, rand].join)
end
end
通过以下迁移:
class CreateInvites < ActiveRecord::Migration
def change
create_table :invites do |t|
t.string :email
t.integer :calendar_id
t.integer :sender_id
t.integer :recipient_id
t.string :recipient_role
t.string :token
t.timestamps null: false
end
end
end
我使用邀请模型通过以下InvitesController
:
class InvitesController < ApplicationController
def create
@invite = Invite.new(invite_params) # Make a new Invite
@invite.sender_id = current_user.id # set the sender to the current user
@calendar = Calendar.find_by_id(@invite.calendar_id)
authorize @calendar
if @invite.save
InviteMailer.invite(@invite).deliver #send the invite data to our mailer to deliver the email
else
format.html { render :edit, notice: 'Invitation could not be sent.' }
end
redirect_to calendar_path(@calendar)
end
private
def invite_params
params.require(:invite).permit(:email, :calendar_id)
end
end
以下是InviteMailer
:
class InviteMailer < ApplicationMailer
def invite(invite)
@link = new_user_registration_path invite_token: invite.token
mail to: invite.email, subject: "Calendy Invitation"
end
end
这是相应的邮件程序视图:
You've been invited to join a calendar.
Click here to view this calendar: <%= @link %>
当我创建邀请并检查服务器上的日志时,我可以看到邮件已生成以下电子邮件:
InviteMailer#invite: processed outbound mail in 13.7ms

Redirected to http://localhost:3000/calendars/3
我有两个问题:
我不明白为什么我在电子邮件中有/account/sign_up?invite_token=cf7fb2ab8ad0774a99c1cdf7baf0bd44796c2f0f
而不是http://localhost:3000/calendars/3/account/sign_up?invite_token=cf7fb2ab8ad0774a99c1cdf7baf0bd44796c2f0f
我不确定由<%= @link %>
生成的上述链接是否可点击。当我尝试使用<%= link_to @link %>
,as recommended here进行点击时,我收到以下错误:
Invites #create中的ActionController :: UrlGenerationError 没有路线匹配{:action =&gt;&#34; index&#34;}
您已被邀请加入日历。 点击此处查看此日历:&lt;%= link_to @link%&gt;
错误来自第Click here to view this calendar: <%= link_to @link %>
行
我非常感谢有关上述项目的任何见解。
有什么想法吗?
答案 0 :(得分:3)
使用new_user_registration_url
代替new_user_registration_path
_path
帮助程序提供站点根目录相对路径。你应该在大部分时间都使用它。
_url
帮助程序提供绝对路径,包括协议和服务器名称。我发现在创建服务器上的应用程序链接时,我主要在电子邮件中使用这些。它们应主要在提供外部链接时使用。 (想想电子邮件链接,RSS,以及YouTube视频“分享”部分下的复制和粘贴网址字段。)
在邮件程序类中使用link_to
是一件坏事
class InviteMailer < ApplicationMailer
def invite(invite)
@invite = invite
mail to: invite.email, subject: "Calendy Invitation"
end
end
梅勒观点:
Click here to view this calendar: <%= link_to "link", new_user_registration_url(invite_token: @invite.token) %>
