Question: I am new to SailsJS and stuck in Data Model as follows:  

I have a `User` model as follows: 

```
module.exports = {
attributes: {
firstName: {
    type: 'string'
},
email: {
    type: 'email',
    required: true
},

password: {
    type: 'String'
},
passwordSalt: {
 type: 'String'
},
projects:{
 collection: 'ProjectMember',
 via: 'userId'
}  
}  
};  

```

Task Model : 

```
module.exports = {  
 taskName: {  
  type: 'String'  
 },  
 userId: {  
    model: 'User'  
 }
};  

```

In Task model, it is getting all fields from User table which is not required while task data is rendered. I was planning to create one more model called `TinyUser` which stores only required fields to be shown when task data is rendered. 

But `TinyUser` should just refer `User` table and get required data from it rather than we creating all data for TinyUser manually when user data is created. 

Is there any way this can be achieved in Sails?  

Thanks in Advance..

Answer: 
I'm not sure about your question, but this will return a list of required attributes for any model

```
_.find(sails.models.<YOUR MODEL>._attributes, function(attr){return attr.required})

```

If your intent it to simply remove undesirable fields you can override the toJSON / toObject methods

see
<https://github.com/balderdashy/waterline-docs/blob/master/models.md#toobjecttojson-instance-methods>
User.find({select:['firstName', 'email']}).exec()
