无法用Mailer在Rails中发送链接

Question

我有一个应用程序，发送邀请电子邮件，其中包含一个链接注册。但是寄存器链接会出现错误。如果注册链接不存在，电子邮件将发送。

NoMethodError in Invitations#create
undefined method `accept_referral_invitation_url' for #(#(Class:0xadd8c90):0xb5d868cc)

此错误发生在这一行。

= accept_referral_invitation_url(@invitation.invite_token)

InvitationsController

class InvitationsController < ApplicationController
    def new
        @invitation = Invitation.new
    end

  def create
  @invitation = current_user.invitations.new(params[:invitation])

    if @invitation.valid?
      @invitation.save
      redirect_to root_url, :notice => "Invitation sent!"
      UserMailer.invitation(@invitation).deliver
    else
      render "new", :notice => "Somehting went wrong!"
    end
end


  def accept_referral
      @invitation = Invitation.find_by_invite_token(params[:invite_token])
      @invitation.accepted_at = Time.zone.now
      @invitation.save!
      redirect_to root_url, :notice => "Success!"
  end

end

用户邮箱

class UserMailer < ActionMailer::Base
  def invitation(invitation)
    @invitation = invitation
    mail(:to => invitation.email, :subject => "You're invited", :from => 'alain@lootfly.com')
  end
end

invitation.html.haml (被发送的消息)

You have been cordially invited to join beta.
Click this link to sign up!
= accept_referral_invitation_url(@invitation.invite_token)
= accept_referral_invitation_url(invite_token: @invitation.invite_token)
# I TRIED BOTH OF THOSE LINKS^^^^ TO NO AVAIL!!!!!!!

邀请模型

  create_table "invitations", :force => true do |t|
    t.integer  "user_id"
    t.text     "email"
    t.text     "invite_token"
  end

编辑: Rake路由

        invitations GET    /invitations(.:format)                invitations#index
                    POST   /invitations(.:format)                invitations#create
     new_invitation GET    /invitations/new(.:format)            invitations#new
    edit_invitation GET    /invitations/:id/edit(.:format)       invitations#edit
         invitation GET    /invitations/:id(.:format)            invitations#show
                    PUT    /invitations/:id(.:format)            invitations#update
                    DELETE /invitations/:id(.:format)            invitations#destroy

Answer 1

您可能在config/ this es.rb中缺少了这一点。

resources :invitations do
  get 'accept_referral', :on => :collection 
end

，这将生成一个GET目标，如接受邀请的/请柬/ accept _referral，因此您可以这样做。

accept_referral_invitations_url()

现在，要获得邀请代码，请执行以下操作：

accept_referral_invitations_url(:invite_token => @invitation.invite_token)

，这将导致一个类似于/invitations/accept_referral?invite_token=blahblahblah的URL

请注意，我在集合中添加了GET目标(而不是成员)，因此不需要传递@ itself对象本身。而且，因为它是一个集合目标，所以使用invitations_url (复数)而不是invitation_url。

希望这能帮上忙！

Answer 2

错误中的Invitations对象是可疑的，因为Rails通常不会创建这个名称的类(即没有限定符的复数)。您应该检查您的Invitation类定义是否不正确地使用该对象名称。
