如何在南迁移期间调用django模型类上的静态方法

from django.db import models

class MyModel(models.Model):
    name = models.CharField(max_length=100)

    @staticmethod
    def my_static_method(arg1, arg2):
        # 在这里编写静态方法的代码
        pass

from django.http import HttpResponse
from .models import MyModel

def my_view(request):
    result = MyModel.my_static_method(arg1, arg2)
    return HttpResponse(result)

from django.db import migrations
from .models import MyModel

class Migration(migrations.Migration):
    dependencies = [
        ('myapp', '0001_initial'),
    ]

    operations = [
        migrations.RunPython(MyModel.my_static_method(arg1, arg2)),
    ]
