Django Import-Export:管理界面"TypeError at /"

我想弄清楚如何使用Django Import-Export,

https://pypi.python.org/pypi/django-import-export

通过阅读文档

https://django-import-export.readthedocs.org/en/latest/getting_started.html#admin-integration

管理集成:

对于我的基本python知识,示例代码与其后面的结果照片之间的差距似乎很大.

我设法编写以下代码:

geographic_system/models.py:

from django.db import models
from django.utils.translation import ugettext_lazy as _

class Regional_Units(models.Model):
    regional_unit = models.CharField(
        max_length=64, verbose_name=_(u'Regional Units'))

    def __unicode__(self):
        return u'%s' % (self.regional_unit)

geographic_system/resources.py:

from import_export import resources
from geographical_system.models import Regional_Units
from import_export.admin import ImportExportModelAdmin


class Regional_Units_Resource(resources.ModelResource):

    class Meta(object):
        model = Regional_Units


class Regional_Units_Resource_Admin(ImportExportModelAdmin):
    resouce_class = Regional_Units_Resource # Why originally commented out?
    #pass #Why pass?

geographic_system/admin.py:

from django.contrib import admin
from geographical_system.models import Regional_Units
from geographical_system.resources import Regional_Units_Resource_Admin


admin.site.register(Regional_Units)
admin.site.register(Regional_Units_Resource_Admin)  # **Improvising here**, otherwise nothing would happen

导致的错误

当然,我的即兴创作admin.site.register(Regional_Units_Resource_Admin)在访问时产生了以下信息

http://127.0.0.1:8000/admin/geographical_system/regional_units/

问题

为什么会出现此错误？

我怎么能最终进入这个美丽的管理界面,其中启用了导入和导出选项？

虽然我不熟悉这个特定的应用程序,但你应该做的是替换

admin.site.register(Regional_Units)
admin.site.register(Regional_Units_Resource_Admin)

同

admin.site.register(Regional_Units, Regional_Units_Resource_Admin)

如果一切正常,它应该工作.admin register()方法期望Model作为第一个参数,并且(可选)将ModelAdmin类(或子类)作为第二个参数.

旁注:因为你刚刚开始使用python/django尝试遵守约定.这意味着不要_在类Names中的单词之间使用(即RegionalUnits是一个合适的名称)并尝试ModelAdmin在admin.py模块中放置声明(即RegionalUnitsResourceAdmin应该在admin.py中声明而不是导入).
