用戶可以創建組織,然後他可以讓其他用戶成爲其組織的主持人。下面的方法顯示了組織是如何創建的。Rails has_many通過

def create             
    @organization = current_user.organizations.build(organization_params) 

    # Confirm organization is valid and save or return error 
    if @organization.save! 
    # New organization is saved        
    respond_with(@organization) do |format|     
     format.json { render :json => @organization.as_json } 
    end 
    else 
    render 'new', notice: "Unable to create new organization." 
    end 
end 

我應該如何爲組織創建主持人。我嘗試過使用has_many,但失敗了。有人能幫助我嗎?

更新

組織模型

class Organization < ActiveRecord::Base 
    has_many :moderators 
    has_many :users, :through => :moderators 
end 

的usermodel

class User < ActiveRecord::Base 
    enum role: [:user, :moderator, :organization, :admin] 
    after_initialize :set_default_role, :if => :new_record? 

    def set_default_role 
    self.role ||= :user 
    end 

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

    has_many :moderators 
    has_many :organizations, :through => :moderators 
end 

主持人型號

class Moderator < ActiveRecord::Base 
    belongs_to :user 
    belongs_to :organization 
end 

當我創建新組織時,我的組織user_id是否爲零?
