I use something like this in a function that creates forms for most
of my models with some special processing based on related fields:
for n in object_instance._meta.fields:
if n.verbose_name == 'RELATED_FOREIGNKEY_MODEL_VERBOSE_NAME':
#Model has FK relation
for n in object_instance._meta.many_to_many:
if n.verbose_name == 'RELATED_M2M_MODEL_VERBOSE_NAME:
#Model has m2m relation
the ._meta.fields and ._meta.many_to_many are attributes of the model
itself so:
Model._meta.fields and Model._meta.many_to_many work as well
You can also simply introspect the instance itself to find out the
model worked with:
object_instance._meta.verbose_name
