ruby-on-rails - 无法使用Mailer在Rails中发送链接

我有一个应用程序，它发送一封邀请电子邮件，其中包含要注册的链接但是寄存器链接给出了一个错误如果注册链接不存在，则会发送电子邮件。

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

这条线上发生了错误

= accept_referral_invitation_url(@invitation.invite_token)

邀请控制器

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

用户邮件发送程序

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

invitation.html.haml（已发送的邮件）

You have been cordially invited to join beta.

= 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管线

        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

最佳答案

您可能在config/routes.rb中缺少这个

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

它将生成一个GET target-like/invitations/accept_引用，该引用将接受邀请，因此您可以

accept_referral_invitations_url()

现在，要获取邀请代码，请执行以下操作：

accept_referral_invitations_url(:invite_token => @invitation.invite_token)

这将导致类似于/invitations/accept_referration的URL？invite_token=blahblahblah邀请
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@invitation对象本身。而且，因为它是一个集合目标，所以您使用invitation s-url（复数）而不是invitation-url。
希望能有帮助！
