Question

我有这些关系的应用程序：

用户可以创建许多项目
所有者可以邀请其他用户作为成员
如果用户接受所有者邀请他成为会员，如果他拒绝，则什么也没发生。

现在，这是模特：

project.rb

class Project
  include Mongoid::Document

  field :title, type: String
  field :description, type: String
  field :client, type: String
  field :deadline, type: String

  belongs_to :owner, :class_name => 'User', inverse_of: :projects
  has_many :members, :class_name => 'User', inverse_of: :projects
end

user.rb

class User
  include Mongoid::Document
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  ## Database authenticatable
  field :email,              type: String, default: ""
  field :encrypted_password, type: String, default: ""
  field :username, type: String, default: ""

  # Invitations
  field :project_invitations, type: Array, default: []

  has_many :projects, inverse_of: :user

end

以下是 invites_controller.rb ，用于管理所有邀请系统（接受/拒绝邀请，创建邀请等）：

class InvitesController < ApplicationController

    def new 
        @invite = Invite.new(email: params[:search], sender_id: current_user.id)
    end

    def create
        @project = Project.find(params[:project_id])
        recipient = User.find_by(email: params[:search])
        @invite = Invite.new(email: params[:search], sender: current_user.id, recipient: recipient, project_id: @project, accepted: false)
        if @invite.save
            flash[:success] = 'the invitation is sent'
            recipient.push(project_invitations: @invite._id )
            recipient.save
            redirect_to project_path(@project)
        else
            flash[:error] = 'something went wrong'
            puts @invite.errors.full_messages
            render :back
        end
    end

    def accept
        @invite = Invite.find_by(id: params[:project_id])
        @user = current_user
        @invite.accepted = true
        @user.project_invitations.delete(@invite._id)
        @invite.save
        @user.save
        @project.member = @user
    end

    def decline
        @invite = Invite.find_by(id: params[:project_id])
        @user = current_user
        @project = Project.find(params[:project_id])
        @invite.accepted = false
        @user.project_invitations.delete(@invite._id)
        @invite.save
        @user.save
    end

end

以下是问题：

在我的项目模型中，我有：所有者和：成员，接受邀请的用户怎么可能成为：项目成员？我写has_many :members，但我不知道如何设置普通用户成为：member ..

修改

你认为创建一个数组字段应该是一个很好的ID我会把所有users_id（谁是成员）？

谢谢！

Answer 1

会员资格与特定项目有关。您的项目有许多成员，需要以某种方式反映其数据结构。我设想一个包含一堆用户外键和项目外键的成员表。然后，您可以尝试通过userID和projectID查找成员，以确定他们是否在任何时候都是成员？虽然不太确定，但我还没有经验，所以我很想听听其他人说的话。
