How can i use a one form/table for multiple MVC's?

I cant really wrap my head around how to do this since I'm new at RoR.I have a Price model which is the only table i want to use for forms. I want to have 2 other MVCs that are UserData and Search.

The scenario is Users can input Prices and these Prices have 3 places to go. It can be their Data area, Search area or both areas. But the twist is Data area will have my parts on the for开发者_Go百科m like the category of price and same goes with the Search area, that form you can put tags on it.

So how do i set it up so i am using my Prices form for the other 2 MVCs?

EDIT:

User has_many Prices

UserData has_many Prices and Category belongs_to UserData

Search has_many Prices and Tag belongs_to Search

Price Form = price name, date, and cost only.

UserData + Price Form + Category model = price name,date,cost and category.

Search + Price form + Tag Model = price name,date,cost and tags of price ( vegetables, candy?)

Hi If you're using rails 3 check http://railscasts.com/episodes/269-template-inheritance if older version you should create folder shared under your views directory and place there partial _price_form and render it on page http://guides.rubyonrails.org/layouts_and_rendering.html - guide on rendering
