ruby-on-rails - 从其他模型更改数据

Question

我想知道我应该接受什么样的查询才能更新我的数据。我的模型由客户、兴趣和经理组成

Clients his has follow
id
name
email
password

Interest
id
description

manager
customer_id
interest_id
created_at

经理的目标不是覆盖感兴趣的旧数据，而只是不断添加新的兴趣并引用它。

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

现在要更新来自客户控制器的数据，我不确定我会怎么做这就是我正在考虑的：

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

这有意义吗？还是我错了？

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

或者我应该根据兴趣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 - 在控制台中尝试一下！
