Question

我想知道我应该接受什么样的查询来允许我的数据更新。我的模型包括客户，兴趣和经理

Clients his has follow
id
name
email
password

Interest
id
description

manager
customer_id
interest_id
created_at

经理的目标是他不要覆盖感兴趣的旧数据，而只是不断添加新兴趣并引用它。

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

现在要更新客户控制器的数据我不知道如何做到这一点这就是我在想的：

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

这有意义吗？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

或者我应该从感兴趣的角度渲染模型视图然后应用更改？

Answer 1

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

应该可以工作 - 在控制台中试试！

从其他模型更改数据
