Description

Datatype for the EntitySchemaService transforming values to "string".

This type is automatically used if you annotate a class's property that has the TypeScript type "string" ensuring that even if values in the database from other sources are not of type string, the property will be a string.

For example:

@DatabaseField() myString: string;

@DatabaseField({dataType: 'string'}) myValue: any;

importIncompleteAdditionalConfigBadge
importIncompleteAdditionalConfigBadge(col: ColumnMapping)
Inherited from DefaultDatatype
Defined in DefaultDatatype:140

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

importMapFunction(val: any, schemaField: EntitySchemaField, additional?: any, importProcessingContext?: any)
Inherited from DefaultDatatype
Defined in DefaultDatatype:113

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 | []>

Optional importConfigComponent
Type : string
Inherited from DefaultDatatype
Defined in DefaultDatatype:132

A component to be display as a dialog to configure the transformation function (e.g. defining a format or mapping)
viewComponent
