Rails的3.2.6。加入2表,并选择记录(表2),以形成(表1)与下拉选 [英] Rails 3.2.6. Join 2 tables and select record(table2) to form(table1) with drop-down-select
问题描述
我想加入2表,我有一个表人和一张桌子工厂。 我的问题是,我如何才能增加一个人,不是选择(有下拉)工厂的人是属于?
i would like to join 2 tables i have a table 'persons' and a table 'factories'. My question is, how can i add a person and than choose (with a dropdown) the factory the person belongs to?
我的人模型:
class Person < ActiveRecord::Base
has_many :factories
has_attached_file :cv
attr_accessible :cv, :email, :function, :mobile, :telephone
end
我的工厂模式:
My factories model:
class Factory < ActiveRecord::Base
belongs_to :persons
attr_accessible :last_name, :email, :telephone, :first_name, :website, :country
end
我想这样做,例如:
I want to do it for example:
|添加个人|
功能:(输入字段)
电话:(输入字段)
手机:(输入字段)
电子邮件:(输入字段)
Email: (input field)
厂(下拉)LT; =这是实际的领域我想有,它是默认情况下不放置在人员表
Factory (Drop-down) <= this is the actual field i would like to have and it is not placed in the persons table by default.
CV:(上传域)
提交:(提交按钮)
我希望你明白我想有,我希望有人可以帮助。
I hope you understand what i would like to have and i hope someone could help.
感谢。
修改1 我改变了我的计划。我想有一个选择的factory.id在人员表中的列。 我在Person表做了一个列名为factory.id现在我想以从该列中的其他表存储数据。 这可能吗?
EDIT 1 i changed my plans. I would like to have a chosen factory.id in a column in the persons table. I made a column in my Person table with the name factory.id now i would to to store the data from the other table in that column. Is this possible?
推荐答案
您也许可以做到这一点:
You can probably do this:
控制器:
@people=Person.new
@factories = Factory.all
查看:
form_for @people do |a|
.
.
.
= a.select :factory, options_for_select(@factories.map{ |f| [f.name, f.id] })
