When you get a workbook with the TSC library, the response from Tableau Server does not include information about the views or connections that make up the workbook. Similarly, when you get a data source, the response does not include information about the connections that make up the data source. This is a result of the design of the Tableau Server REST API, which optimizes the size of responses by only returning what you ask for explicitly.
As a result, if you want to get views and connections, you need to call the populate_views and populate_connections
functions.
workbook = server.workbooks.get_by_id('a1b2c3d4')
print(workbook.id)
server.workbooks.populate_views(workbook)
print([view.name for view in workbook.views])
workbook = server.workbooks.get_by_id('a1b2c3d4')
print(workbook.id)
server.workbooks.populate_connections(workbook)
print([connection.datasource_name for connection in workbook.connections])
datasource = server.datasources.get_by_id('a1b2c3d4')
print(datasource.name)
server.datasources.populate_connections(datasource)
print([connection.datasource_name for connection in datasource.connections])
