Now let’s create some instances of this model using shell, run form bash,
Python manage.py shell
Enter following commands
>>> from geeks.models import GeeksModel >>> GeeksModel.objects.create( title="title1", description="description1").save() >>> GeeksModel.objects.create( title="title2", description="description2").save() >>> GeeksModel.objects.create( title="title2", description="description2").save()
