创建具有未知领域的格式，并存储这些字段成一个序列化的提出在我的模型 [英] Creating a form with unknown fields and storing those fields into a serialized filed in my model

问题描述

我有，将有两个一组动态和已知的字段集的形式。我需要在数据库中存储动态字段的方式，我已经决定将其存储在一个序列化的领域，因为我不需要搜索的数据，而我只需要存储并在需要时调出。

I have a form that will have both a dynamic set and a known set of fields. I need a way of storing the dynamic fields in the database and I have decided on storing them in a serialized field, as I will not need to search on the data, and I just need it stored and recalled when needed.

class MyApplication < ActiveRecord::Base
    has_one :applicant
    belongs_to :member

    serialize :additional_fields, Hash

    accepts_nested_attributes_for :applicant, :additional_fields

我在想有形式返回的字段作为additional_fields_attributes并以某种方式有模特大赛storying散入additional_fields节之后。林不知道如果我尽量去当使用类似的方法缺少照顾这一点，或者我是否应该取消的accepts_nested_attributes_for和处理它在我自己的。

I was thinking of having the form return the fields as an additional_fields_attributes and somehow have the model look after storying the hash into the additional_fields section. Im not sure if I have to go as far as using something like method missing to look after this, or if I should scrap the accepts_nested_attributes_for and handle it on my own.

有没有人有什么想法？

谢谢！瑞安
