object

Validates to the property to a valid object. Further you can define the shape of the object properties using the object.members() method.

In the following example, we expect the profile to be an object with the username and the avatar_url properties.

import { schema } from '@ioc:Adonis/Core/Validator'

{
  profile: schema.object().members({
    username: schema.string(),
    avatar_url: schema.string()
  })
}

// Valid data: { profile: { username: 'virk', avatar_url: 'somefile.jpg' } }

Mark as optional

You can mark the property to be optional by chaining the optional method. The undefined and the null values are considered optional and removed from the validated object.

{
  profile: schema.object
    .optional() // 👈
    .members({
      username: schema.string(),
      avatar_url: schema.string()
    })
}

Mark as nullable

You can mark the property to be nullable by chaining the nullable method. The nullable fields must exist in the payload but can contain null values.

{
  profile: schema.object
    .nullable() // 👈
    .members({
      username: schema.string(),
      avatar_url: schema.string()
    })
}

Mark as nullable and optional

Mark the property both as nullable and optional. If the field value is undefined, it will be removed from the validated object. Otherwise, the validated value (including null) is returned.

{
  profile: schema.object
    .nullableAndOptional() // 👈
    .members({
      username: schema.string(),
      avatar_url: schema.string()
    })
}

Accept any elements

You can also define an object that accepts any properties. The object properties are not further validated to have a specific type.

{
  colors: schema.object().anyMembers()
}
