JsonDataSource class Leave feedback

Provides access to data of a JSON file or stream to be used while assembling a document.

To access data of the corresponding file or stream while assembling a document, pass an instance of this class as a data source to one of DocumentAssembler overloads.

In template documents, if a top-level JSON element is an array, a JsonDataSource instance should be treated in the same way as if it was a System.Data.DataTable instance. If a top-level JSON element is an object, a JsonDataSource instance should be treated in the same way as if it was a System.Data.DataRow instance. For more information, see the template syntax reference (https://docs.groupdocs.com/assembly/python-net/template-syntax-part-1-of-2/).

In template documents, you can work with typed values of JSON elements. For convenience, the engine replaces the set of JSON simple types with the following one:

• long?
• double?
• bool?
• DateTime?
• string

The engine automatically recognizes values of the extra types upon their JSON representations.

To override default behavior of JSON data loading, initialize and pass a JsonDataLoadOptions instance to a constructor of this class.

The JsonDataSource type exposes the following members:

from groupdocs.assembly import DataSourceInfo, DocumentAssembler
from groupdocs.assembly.data import JsonDataSource

json_data_source = JsonDataSource("staff-member.json")

assembler = DocumentAssembler()
assembler.assemble_document(
    "staff-member-card.docx",
    "staff-member-card-report.docx",
    DataSourceInfo(json_data_source, "data")
)
