af = pd.merge(df, gdf, left_on='DA Code', right_on='DAUID', how='left')
af.to_file("output.geojson", driver="GeoJSON")

I am trying to export my geopandas dataframe adfter a merge. the orginal gdf is experting fine but the new one is giving me this error

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-47-85d4fd06b055> in <module>
----> 1 af.to_file("output.geojson", driver="GeoJSON")

/usr/local/lib/python3.7/dist-packages/pandas/core/generic.py in getattr(self, name)
   5485         ):
   5486             return self[name]
-> 5487         return object.getattribute(self, name)
   5488 
   5489     def setattr(self, name: str, value) -> None:


AttributeError: 'DataFrame' object has no attribute 'to_file'

The merged gdf looks fine. Do I have to declare the geometry column manually? enter image description here

    That's because af is not a gpd.GeoDataFrame it's a pd.DataFrame. Use geopandas merging, not pandas https://geopandas.org/en/stable/docs/user_guide/mergingdata.html – user2856 Nov 10 '22 at 03:27
  • You should convert your df to gdf. See https://gis.stackexchange.com/questions/174159/converting-pandas-dataframe-to-geodataframe – Fardin Esmaeili Nov 10 '22 at 07:05
