class Agents << ActiveRecord::Base
    belongs_to customer
    belongs_to house
end

class Customer << ActiveRecord::Base
    has_many :agents
    has_many :houses :through=>:agents
end

class House << ActiveRecord::Base
    has_many :agents
    has_many :customers :through=>:agents
end

问题 如何添加到代理模式客户？

Question How do I add to the Agents model for Customer?

这是最好的方式？

Customer.find(1).agents.create(:customer_id=>1, :house_id=>1)

以上工作正常，从控制台但是，我不知道如何在实际应用中实现这一目标。

The above works fine from the console however, I don't know how to achieve this in the actual application.

想象一下，一个表单填的客户也需要 house_id 作为输入。然后，我做到以下几点在我的控制器？

Imagine a form is filled for the customer that also takes house_id as input. Then do I do the following in my controller?

def create 
    @cust = Customer.new(params[:customer])
    @cust.agents.create(:customer_id=>@cust.id, :house_id=>params[:house_id])
    @cust.save
end

总的来说，我很困惑，如何在的has_many添加记录：通过表格

推荐答案

我觉得你可以简单地做到这一点：

I think you can simply do this:

 @cust = Customer.new(params[:customer])
 @cust.houses << House.find(params[:house_id])

或者为客户创建一个新的房子的时候：

Or when creating a new house for a customer:

 @cust = Customer.new(params[:customer])
 @cust.houses.create(params[:house])
