将 django import_export 添加到抽象用户模型

Question

下面是我的 admin.py 文件。

我想在抽象用户模型的 Employee 模型上实现 import_export 功能。

from django.contrib import admin
from inventory.models import Employee
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import Group
from import_export.admin import ImportExportModelAdmin
admin.site.unregister(Group)

# admin.site.register(Employee)


class EmployeeAdmin(UserAdmin):
    list_display = ('emp_num', 'emp_name', 'email',
                    'emp_designation', 'is_admin', 'is_staff')
    search_fields = ('emp_num', 'emp_name')

    readonly_fields = ('last_login',)
    ordering = ('emp_num',)
    filter_horizontal = ()
    list_filter = ('is_admin',)
    fieldsets = ()


admin.site.register(Employee, EmployeeAdmin)

Answer 1

该ImportExportModelAdmin [readthedocs.io]仅仅是一个ModelAdmin与ImportExportMixin [readthedocs.io] ，所以可能是最干净的解决方案是使用ImportExportMixin ：

from django.contrib import admin
from inventory.models import Employee
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import Group
from import_export.admin import ImportExportMixin
admin.site.unregister(Group)

# admin.site.register(Employee)


class EmployeeAdmin(ImportExportMixin, UserAdmin):
    list_display = ('emp_num', 'emp_name', 'email',
                    'emp_designation', 'is_admin', 'is_staff')
    search_fields = ('emp_num', 'emp_name')

    readonly_fields = ('last_login',)
    ordering = ('emp_num',)
    filter_horizontal = ()
    list_filter = ('is_admin',)
    fieldsets = ()


admin.site.register(Employee, EmployeeAdmin)
