/**

module.exports = {

  attributes: {
    
    // e.g. "Polly"
    name: {
      type: 'string'
    },
    
    // e.g. 3.26
    wingspan: {
      type: 'number',
      required: true,
      columnType: 'FLOAT'
    },
    
    // e.g. "cm"
    wingspanUnits: {
      type: 'string',
      isIn: ['cm', 'in', 'm', 'mm'],
      defaultsTo: 'cm'
    },
    
    // e.g. [{...}, {...}, ...]
    knownDialects: {
      collection: 'Dialect'
    } 
  }
};

How can I create a date type attribute?
date: {
type: 'string',
columnType: 'Date'
}

^
It may be so??

Three is a section for "Embeds" in the models generated by sails . What is it all about, and how do we use them?
