validator property
Allows users to specify validation rules or expressions for the collection. For more information, see Schema Validation.
New in version 3.2.
The validator option takes a document that specifies the validation rules or expressions. You can specify the expressions using the same operators as the query operators with the exception of $geoNear, $near, $nearSphere, $text, and $where.
Note
- Validation occurs during updates and inserts. Existing documents do not undergo validation checks until modification.
- You cannot specify a validator for collections in the admin, local, and config databases.
- You cannot specify a validator for system.* collections.
Implementation
final Map? validator;
