Django Import-Export: Admin interface "TypeError at /"

I am trying to figure out how to use Django Import-Export,

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

by reading the docs

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

Admin Integration:

The gap between the example code and its resulting photo that follows, seems to be vast for my elementary python knowledge.

I have managed to code the following:

geographical_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)

geographical_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?

geographical_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

Resulting Error

Of course, my improvisation admin.site.register(Regional_Units_Resource_Admin) resulted in the following message when visiting

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

TypeError at /admin/geographical_system/regional_units/

Although I'm not familiar with this particular app, what you should do is replace

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

with

admin.site.register(Regional_Units, Regional_Units_Resource_Admin)

and if everything else is ok it should work. The admin register() method expects the Model as first argument and (optionally) a ModelAdmin class (or subclass) as second argument.

Sidenote: since you're just starting with python/django try to comply with the conventions. This means do not use _ between words in class Names (i.e. RegionalUnits is a suitable name) and try to place ModelAdmin declarations right inside the admin.py module (i.e. RegionalUnitsResourceAdmin should be declared in admin.py rather than being imported).
