Django - 覆盖get_form以根据请求自定义管理表单

from django.contrib import admin
from .models import MyModel

class MyModelAdmin(admin.ModelAdmin):
    def get_form(self, request, obj=None, **kwargs):
        if request.user.is_superuser:
            return super().get_form(request, obj, **kwargs)
        else:
            class CustomForm(self.form):
                class Meta(self.form.Meta):
                    exclude = ('some_field',)
            return CustomForm

admin.site.register(MyModel, MyModelAdmin)
