用户可以创建组织,然后他可以让其他用户成为其组织的主持人。下面的方法显示了组织是如何创建的。Rails has_many通过

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 

我应该如何为组织创建主持人。我尝试过使用has_many,但失败了。有人能帮助我吗?

更新

组织模型

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 

主持人型号

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

当我创建新组织时,我的组织user_id是否为零?
