django many to many save admin

Question

I have a model like :

class MyModel(models.Model):
    name = models.CharField(max_length=100)
    type = models.ManyToManyField(Type, blank=True)

Here from admin I am adding MyModel.

What I want is if the type is not provided while saving then I want the type to be as default like Teacher

type Teacher has not been created. If the type is not provided I want to create the type and assign it if the type is not provided

According to documentation 's example, you can override save_model like this:

@admin.register(MyModel)
class MyModelAdmin(admin.ModelAdmin):
    def save_related(self, request, form, formsets, change):
        if not form.cleaned_data['type']:
            type, created = Type.objects.get_or_create(name="Teacher")
            form.cleaned_data['type'] = [type]
        form.save_m2m()
        for formset in formsets:
             self.save_formset(request, form, formset, change=change)
