Proof of concept, building a has_many, through model relationship and form with Cocoon.

Primary LanguageRuby

Building a has_many, through model relationship and form with Cocoon ↑

This example is about setting up a Recipe book. Recipes have multiple meta properties like their title, a brief description, instructions and the like. Each recipe of course needs ingredients and each ingredient needs quantities of that ingredient for the recipe. What we will be setting up is a relationship of Recipes to Ingredients through Quantities.

A recipe :has_many tags :through quantities. You can add ingredients dinamically in the recipe form. When unlinking an ingredient, it is not deleted, only the link.
