许多表/模型属于Ruby on Rails中的一个主要模型

Question

I am building an app where there is a simple model with only title and description and and that model has different forms that a user can fill and will be displayed under that same title and description in tabular form

Example: main model being car (title: LaFerrari, Description: made by Ferrari) below it a table for engine specs with attributes (type: __, Description: __) and a few more tables.

Every table should belong to a specific car

I am not sure how to go about this problem if there is a gem or i need to create models for every table and which should belong_to main model

A little direction would be helpful

THANK YOU.

Answer 1

Table for Car

t.string :title
t.string :description 

Model for Car

has_one :engine_specs

Table for Engine Specs

t.string :type
t.string :description

Model for Engine Specs

belongs_to :car

This ought to help get you started. Clearly though you are going to need a lot more help than this since you do not understand simple associations. I suggest you read it up by at guides.rubyonrails.org
