Good evening all,
following my application development, I have reached to the stage where I
am about to add some data using data migrations.
I did download some data from OSM (saved as json), added a load data
function but when i run the migrate command I get a keyerror in my
migration files:
File
"/home/qgislinuxadmin/nearbyshops/shops/migrations/0002_auto_20210618_2102.py",
line 18, in load_data
for obj in objects['elements']:
KeyError: 'elements'
which would mean that the key in not in a dictionary.
Any help or advice would be appreciated
Kind Regards
Stathis
