Restrictions
Sub-Document
The restrictions can be used in lists and also in sub-documents, they are used to define the behavior of the lists in the following ways:
- Max Length: maximum number of items in the list
- Min Length: minimum number of items in the list
- Required: must have at least 1 item
- Unique: defines the fields that can not duplicate in the list (does not work for sub-documents, because in the sub-document you can configure constraint)
