Methods

Async anonymize
anonymize(value: string, schemaField: EntitySchemaField, parent: any)
Inherited from DefaultDatatype
Defined in DefaultDatatype:33
Parameters :
Name Type Optional
value string No
schemaField EntitySchemaField No
parent any No
Returns : Promise<any>
transformToDatabaseFormat
transformToDatabaseFormat(value: unknown)
Inherited from DefaultDatatype
Defined in DefaultDatatype:38
Parameters :
Name Type Optional
value unknown No
Returns : any
transformToObjectFormat
transformToObjectFormat(value: unknown)
Inherited from DefaultDatatype
Defined in DefaultDatatype:45
Parameters :
Name Type Optional
value unknown No
Returns : any
Static detectFieldInEntity
detectFieldInEntity(entityOrType: Entity | EntityConstructor, dataTypes: string | string[])
Inherited from DefaultDatatype
Defined in DefaultDatatype:57

Detect the first field of the given datatype(s) in an entity's schema.

Scans the schema for a field whose dataType matches one of the provided strings and returns its property name.

Subclasses typically override this without the extra dataTypes parameter, forwarding their own relevant datatype identifiers.

Parameters :
Name Type Optional Description
entityOrType Entity | EntityConstructor No

An entity instance or entity constructor to inspect.
dataTypes string | string[] No

One or more datatype identifiers to match against.
Returns : string | undefined

The field name of the first matching field, or undefined if none is found.
importIncompleteAdditionalConfigBadge
importIncompleteAdditionalConfigBadge(col: ColumnMapping)
Inherited from DefaultDatatype
Defined in DefaultDatatype:166

Output a label indicating whether the given column mapping needs user configuration for the "additional" config or has a valid, complete "additional" config. returns "undefined" if no user action is required.

Parameters :
Name Type Optional
col ColumnMapping No
Returns : string
Async importMapFunction
importMapFunction(val: any, schemaField: EntitySchemaField, additional?: any, importProcessingContext?: any)
Inherited from DefaultDatatype
Defined in DefaultDatatype:145

The function used to map values from the import data to values in the entities to be created. to share information across processing of multiple columns and rows.

Parameters :
Name Type Optional Description
val any No

The value from an imported cell to be mapped
schemaField EntitySchemaField No

The schema field definition for the target property into which the value is mapped
additional any Yes

config as returned by the configComponent
importProcessingContext any Yes

an object that the datatype can use to store any relevant context across multiple calls to share information across processing of multiple columns and rows.
Returns : Promise<EntityType>
normalizeSchemaField
normalizeSchemaField(schemaField: EntitySchemaField)
Inherited from DefaultDatatype
Defined in DefaultDatatype:182

Return the (potentially adjusted) schema field for this datatype.

Called when schema fields are set up (e.g. from config), allowing the datatype to normalize or fill in required settings.

Override this in a subclass to enforce constraints (e.g. always setting isArray: true).

Parameters :
Name Type Optional Description
schemaField EntitySchemaField No

The current schema field definition
Returns : EntitySchemaField

The schema field to use (default: unchanged)

/** Datatype for saving a photo on an entity property.*/
@Injectable()
export class PhotoDatatype extends FileDatatype {
  static override dataType = "photo";

  override editComponent = "EditPhoto";
}
