You may generate models with as many attrs as you would like to pass. The following attribute types are supported: :array :boolean :date :object :number :string :belongs-to: :has-many: For instance: \`ember generate schema taco filling:belongsTo:protein toppings:hasMany:toppings name:string price:number misc\` would result in the following schema (tacos.js): ```json { "filling": { "type": "proteins", "relationship": "belongsTo" }, "toppings": { "type": "toppings", "relationship": "hasMany" }, "name": "string", "price": "number", "misc": null } ``` and the following model (taco.js): ```js import JSONAPIModel from 'ember-jsonapi/JSONAPIModel'; import tacos from '../schemas/tacos'; export default JSONAPIModel(tacos); ```
