How to get a model object from instance in Django

get_model_object_django

# Sometimes you need to determine a model name from an object, before using

# First long approach may work in every version of Django? not tested
import sys
model_obj # let model_obj be the model object ( instance) from some input

model_name_str = type(model_obj).__name__ # this is model name as string, but we need the object to do the 
model_object = getattr(sys.modules[__name__], model_name_str)

# now we can use model object normally
model_object.objects.all() # etc

# Second pythonic approach Works in Django 1.11
# model_obj is the model instance as input from some function

model_object = model_obj._meta.model.objects.all() # with 1 line we can do what we did above
