How to change database and tables of exported Dashboard file (pickle file)?

[JoeNguyen93]

Assume I have a Dashboard with a slice that points to tableA of dbA.sqlite. After exporting that Dashboard and import it as an Python object in my script in order to modify the database and tables, which attribute I should modify to point the slice to tableB of dbB.sqlite (The tables have the same schema, just different in name) ?

Example file:

import pickle

with open("test_dashboard.pickle", "rb") as f:
    dashboard = pickle.load(f)
    # first_table_obj = dashboard['datasources'][0]
    # print(dashboard['datasources'])
    # print(type(first_table_obj))  # <class 'superset.connectors.sqla.models.SqlaTable'>
    # print('Database id of table:', first_table_obj.database_id)
    dashboard_obj = dashboard['dashboards'][0]
    dashboard_obj.dashboard_title = 'TestDashboard_2'  # Change Dashboard Title
    print('----------')
    # for table in dashboard['datasources']:
    #     table.table_name = '{}_2'.format(table.table_name)
    #     table.database_id = 2
    for slice in dashboard_obj.slices:
        print('Data source of slice:', slice.datasource)  # commit_info and file_info (tables)
        print('Type of datasource:', type(slice.datasource))   # <class 'superset.connectors.sqla.models.SqlaTable'>
        print('Database of slice:', slice.datasource.database)  # Test_Data (db)
        print(type(slice.datasource.database))  # <class 'superset.models.core.Database'>
        print('Table id of the slice:', slice.datasource_id)  # Table id
