nosql model creation, trying to build a product schema with variable product options

Question

I downloaded and installed "Totaljs Eshop" and noticed that the product creation does not allow me to define product options (ie, color of product).

I went into the NoSQL embedded database, and looked at the models/product.js file.

I see:

NEWSCHEMA('Product').make(function(schema) {

schema.define('id', 'String(20)');
schema.define('pictures', '[String]');
schema.define('reference', 'String(20)');
schema.define('category', 'String(300)', true);
schema.define('manufacturer', 'String(50)');
schema.define('name', 'String(50)', true);
schema.define('price', Number, true);
schema.define('priceold', Number);
schema.define('description', String, true);
schema.define('availability', 'String(40)');
schema.define('template', 'String(30)');
schema.define('body', String);
schema.define('pictures2', '[String]');
schema.define('istop', Boolean);
schema.define('isnew', Boolean);
schema.define('linker', 'String(50)');

I tried adding the following code:

schema.define('nicstrength', 'Array(0mg, 1.5mg, 3mg, 6mg, 9mg, 12mg)')

I am getting errors saying:

======= 2017-01-02 02:50:21: Error: Schema: "nicstrength.Array(0mg, 1.5mg, 3mg, 6mg, 9mg, 12mg)" not found in "default". Error: Schema: "nicstrength.Array(0mg, 1.5mg, 3mg, 6mg, 9mg, 12mg)" not found in "default".

I am pretty new to backend, so I apologize if this is a trivial question.

Here is a link to my repository where I forked the initial open source project

you have to define a correct schema type and Array(0mg, 1.5mg, 3mg, 6mg, 9mg, 12mg) is not valid Total.js schema type. Here are all supported types: https://docs.totaljs.com/latest/en.html#api~SchemaBuilder

Quick fix:

schema.define('nicstrength', ['0mg', '1.5mg', '3mg', '6mg', '9mg', '12mg']);

So the field needs to contain only the one value from defined values.
