[Django]-Python Pickle object in Django model

You can use BinaryField to store pickled object.

From comments of the question, you can also use JSONField to store dict from class instance. You can do it like this:

from django.contrib.postgres.fields import JSONField

class YourModel(models.Model):
    data = JSONField()

Lets say you have a class like this(which you want to store):

class YourClass(object):
    a = None
    b = None
    c = None

    def __str__(self):
        return 'Your Class: {}, {}, {}'.format(self.a, self.b, self.c)

Now you can generate dictionary like this:

some_instance = YourClass(a=1, b=2, c=3)
cls_dict = some_instance.__dict__
print(cls_dict)
# {'a': 1, 'b': 2, 'c': 3}

y = YourModel(data=cls_dict)
y.save()

Now you can try restoring Class instance from dictionary like this:

y = YourModel.objects.first()
some_instance = YourClass()
some_instance.__dict__.update(y.data)

print(some_instance)

# 'Your Class: 1, 2, 3'

I will not comment on wether or not it’s wise to use pickled data in the database. But you can use the django-picklefield library to store pickled data:
