Mixins (horizontal inheritance) for sails models.

---

Getting started

• Add a folder api/mixins/ to your project
• Add you first mixin, for example api/mixins/hasCoordinates.js
• Define your attributes which are used by multiple models

Defining shared attributes

Lets take our example: api/mixins/hasCoordinates.js

module.exports = {

  attributes: {
    lat: {
      type: 'float'
    },

    lng: {
      type: 'float'
    }

};

Use the mixin in the model

For example the an address model api/models/Address.js needs the lat and lng attributes:

module.exports = {

  mixins: [
    'hasCoordinates'
  ],

  attributes: {
    street: {
      type: 'string',
      required: true
    },

    zipcode: {
      type: 'string'
    },

    city: {
      type: 'string'
    }
  }
};

and a Point Of Interest model needs the lat and lng attributes:: api/models/PointOfInterest.js

module.exports = {

  mixins: [
    'hasCoordinates'
  ],

  attributes: {
    title: {
      type: 'string',
      required: true
    },

    description: {
      type: 'string'
    }
  }
};
