从其他模型更改数据

Question

我想知道应该接受什么样的查询来允许我的数据更新。我的模型是由客户端，利息和经理

Clients his has follow 
id 
name 
email 
password 

Interest 
id 
description 

manager 
customer_id 
interest_id 
created_at 

经理的目标，他不来覆盖旧的兴趣数据，但只是不断加入了新的兴趣，并指的它的。

The relationship his has follow 
class Client < ActiveRecord::Base 
    has_many :music_interest_managers 
    has_many :music_interests, through => :music_interest_managers 
end 
class MusicInterest < ActiveRecord::Base 
    has_many :music_interest_managers 
    has_many :clients, through => :music_interest_managers 
end 
class MusicInterestManager < ActiveRecord::Base 
    belongs_to :music_interests 
    belongs_to :client 
end 

我们从客户控制器更新数据我不知道如何将我做到这一点 这就是我的想法：

@client = Client.find(params[:id]) 
@manager = @client.manager.build(params[:manager]) 
@interest = @interest.manager.build(params[:interest]) 

这是否有道理？或者我错了？

更新：

def update 
    @client = Client.find(params[:id]) 
    @interest = @client.music_interests.build(params[:interest]) 

    if @client.update_attributes(params[:client]) 
     flash[:success] = "Profile updated" 
     #sign_in @client 
     redirect_to @client 
    else 
     render 'edit' 
    end 
end 

或者我应该给予利息的模型图，然后向变化？

Answer 1

@client = Client.find(params[:id]) 
@interest = @client.music_interests.build(params[:interest]) 

应该工作 - 在控制台中试用！
