Error in admin panel Tle page when TLE doesn't have a related satellite
When a Satellite
is deleted related Tle
model entries are updated to satellite=NULL
.
In this case Admin panel Tle page throws an error and doesn't load. The issue is that in https://gitlab.com/librespacefoundation/satnogs/satnogs-db/-/blob/master/db/base/admin.py#L505 function we don't take care the NULL
satellite
field. We should fix this by return empty name in these cases.
