Question

我正在构建一个邀请系统，用户可以邀请朋友，将他们的user.id设置为数据库中的sender字段，或者请求邀请，该邀请应设置{{1 }到'0'（整数字段）。

用户模型

sender

邀请模式

...
has_many :invites, :class_name => 'Invitation', :foreign_key => 'sender' #sent_invitations
belongs_to :invitation
...

邀请控制器

belongs_to :sender, :class_name => 'User'
has_one :recipient, :class_name => 'User'

正在创建邀请（我可以在数据库中看到它），但未设置发件人。这是dev_log：

的输出形式

def create
    @invitation = Invitation.new(invitation_params)
    if current_user?
      @invitation.sender = current_user
      if @invitation.save
        redirect_to invitations_url, notice: 'Thank you. Your invitation has been sent.'
      else
        render action: "new"
      end
    else
      @invitation.sender = 0
      if @invitation.save
        redirect_to invitations_url, notice: 'Thank you. You request is being processed..'
      else
        render action: "new"
      end
    end
  end

我很难过，因为＃1，我没有创建任意属性“sender_id”。数据库中适用的列是“sender”，＃2，POST没有设置Started POST "/invitations" for 127.0.0.1 at 2016-05-14 17:49:54 -0600 Processing by InvitationsController#create as HTML Parameters: {"utf8"=>"✓", "authenticity_token"=>"aCasBmkfw0m1T/EwuBUlXTA/z+REEWo3Hpv2HpB9w6s=", "invitation"=>{"name"=>"john", "surname"=>"public", "recipient_email"=>"jp@sasdf.com"}, "commit"=>"Create Invitation"} User Load (0.0ms) SELECT "users".* FROM "users" WHERE "users"."auth_token" = 'i__MG0iqyoIND68k6qJmvw' LIMIT 1 DEPRECATION WARNING: You're trying to create an attribute `sender_id'.

我做错了什么？

Answer 1

我无法找到我的问题的答案，所以我把它变成了猴子。

由于我从invitation.sender发送邀请时能够保存current_user，其余的只是在数据库中设置任何内容（NULL），我更改了invitations_controller.rb中的查询参数，以查找所有公司发送的邀请的@invitation.sender = nil。

除非有人发布更好的回复，否则我会把它留下来。干杯！
