Example

// Initalise a model
db.model('user', {
  fields: {
    name: { type: 'string' },
    address: { city: { type: 'string', minLength: 10 } }
  }
})

await db.user.validate({
  name: 'Martin Luther',
  unknownField: 'Some data'
})
// { name: "Martin Luther" }

await db.user.validate({
  name: 'Martin Luther'
  address: { city: 'Eisleben' }
})
// Error [{
//   detail: "Value needs to be at least 10 characters long.",
//   status: "400",
//   title: "address.city",
//   meta: {
//     field: "city",
//     model: "user",
//     rule: "minLength"
//   }
// }]

Blacklisting

Depending on the update option, you can augment the model’s insertBL or updateBL by passing a custom blacklist:

// Prevents `name` and `pets.$.name` (array) from being returned.
user.validate({}, { blacklist: ['name', 'pets.name'] })
// You can also whitelist any blacklisted fields found in insertBL/updateBL
user.validate({}, { blacklist: ['-name', '-pet'] })
