Look at this example:

we have our model

 class Person(models.Model): name = models.CharField(max_length=50) last_name = models.CharField(max_length=200)

Now we create our person object:

 person = Person.objects.create(name='Pepito', last_name='Perez')

this will create the "person" object and to save it is as follows

 person.save()
