在django admin上注册4个参数-TypeError：register（）最多接受3个参数（给定4个）

Question

这是我的代码。.我知道我没有被允许在django admin.py中给register（）提供4个参数，但是我想将ProductAdmin和ProductExportImportAdmin一起用于Product模型。是否可以这样做？ 有办法吗？

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.contrib import admin

from .models import Supplier, Customer, Product, PoOrder
from import_export.admin import ImportExportModelAdmin
from import_export import resources


class ProductResource(resources.ModelResource):

    class Meta:
        model = Product
        exclude = ('id', 'created_at', 'edited_at',)


class ProductExportImportAdmin(ImportExportModelAdmin):
    resource_class = ProductResource


class ProductAdmin(admin.ModelAdmin):
    search_fields = ['code','name']


admin.site.register(Supplier)
admin.site.register(Customer)
admin.site.register(Product, ProductAdmin, ProductExportImportAdmin)
admin.site.register(PoOrder)
