Ruby on Rails generates model field:type - what are the options for field:type?

Question

I\'m trying to generate a new model and forget the syntax for referencing another model\'s ID. I\'d look it up myself, but I haven\'t figured out, among all my Ruby on Rails

Answer 1

It's very simple in ROR to create a model that references other.

rails g model Item name:string description:text product:references

This code will add 'product_id' column in the Item table
