Patch for `dbt show` for a model with a `struct` column containing a `json` datatype #974

matt-winkler · 2023-10-21T21:48:36Z

resolves #972

Problem

dbt show --select currently breaks when attempted on a json field because of this bigquery python client issue

Solution

Patch as suggested by @dbeatty10

# Override broken json deserializer for dbt show --inline
def _json_from_json(value, _):
    """NOOP string -> string coercion"""
    return json.loads(value)

bigquery._helpers._CELLDATA_FROM_JSON["JSON"] = _json_from_json

I left one minor comment that doesn't affect functionality. I'm providing an approval so that you can merge following that update.
