This PR resolves an issue where
gbq._Dataset.datasets()
would not return all datasets under a Google BigQuery project.If
'nextPageToken'
is populated, then anotherdatasets().list()
request should be sent with'pageToken'
set to collect more results.In the past few days, additional datasets were added under the Google BigQuery project id used by pandas as part of the following github project : https://github.com/pydata/pandas-gbq . The addition of datasets caused many gbq unit tests to fail because in function
clean_gbq_environment()
, we check to see if the dataset exists using the incomplete results fromgbq._Dataset.datasets()
before we attempt to delete it.https://github.com/pandas-dev/pandas/blob/master/pandas/tests/io/test_gbq.py#L218
