Question

我有一个应用程序发送包含注册链接的邀请电子邮件。但是寄存器链接给出了错误。如果没有注册链接，电子邮件将发送。

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

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

用户邮件程序

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 （已发送的消息）

= 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

        invitations GET    /invitations(.:format)                invitations#index
                    POST   /invitations(.:format)                invitations#create
     new_invitation GET    /invitations/new(.:format)            invitations#new

         invitation GET    /invitations/:id(.:format)            invitations#show
                    PUT    /invitations/:id(.:format)            invitations#update
                    DELETE /invitations/:id(.:format)            invitations#destroy

Answer 1

你可能在config / routes.rb中错过了这个

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

这会产生一个GET目标，比如/ invitations / accept_referral会接受邀请，所以你可以做

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)

哪个会产生像/ invitations / accept_referral这样的网址？invite_token = blahblahblah

请注意，我在集合（而不是成员）上添加了GET目标，因此我不需要传递@invitation对象本身。而且，因为它是一个集合目标，所以你使用invitations_url（复数）而不是invitation_url。

希望有所帮助！

Answer 2

错误中的Invitations对象是可疑的，因为Rails通常不会创建该名称的类（即没有限定符的复数）。您应检查Invitation类定义是否正确使用该对象名称。
