Exploring the functionality of Array attributes within a Sails.js model

Hello, I am new to sails and I'm trying to create a model API that will produce the following output:

[ 
  { 
    "icon" : [ 
      {"name":"ico1", "ico_typ":"fb", "ico_content_URL":"someLocation"},
      {"name":"ico2", "ico_typ":"tw", "ico_content_URL":"someLocation"},
      {...}
      ]
      "createdAt":
      "updatedAt":
     
  } 
]

I initially thought I could achieve this by passing the icon attribute as an Array, but the issue is that it passes the entire array as a string when I load it in REST CLIENT. Additionally, I am unable to validate the values inside the array, such as ensuring each object has ico_type and URL before loading into the database. Any suggestions on how to properly use arrays in this context would be greatly appreciated! Thank you so much! Sails_v0.11.0 MongoDB_3.0.1

Answer №1

To implement in your model, create a method called

convertToJSON: function () {
   var data = this.toObject();
   // Assuming the object contains icons information like `[{"name":"icon1","type":"facebook","contentURL":"someLocation"},{"name":"icon2","type":"twitter","contentURL":"someLocation"}]`
   data.icons = JSON.parse(data.icons)
   return data;
},

Answer №2

It appears that the model provided by WaterLine is already in JSON format, so all you have to do is send the appropriate response.

res.json(model);
