更新 2:在 models.py
class Offer(TimeStampMixin, SEOFieldsMixin):

discription = models.TextField(u'Красивое описание оффера', null=False, blank=False)

tags = TagAutocompleteField(blank=False, verbose_name='Теги')

publish = models.BooleanField(u'Показывать на сайте?', default=True)
def preview_image(self):
# try:

verbose_name_plural = u'Предложения'
ordering = ('-modified_value',)
get_latest_by = 'created_value'
def __unicode__(self):
return u'%s' % self.title
我没有找到管理类只有这个:
from django.contrib import admin
from app.motivity.models import TaskOffer, Offer, UserOffers
class TaskOfferAdmin(admin.TabularInline):
model = TaskOffer
exclude = ['meta_title', 'meta_description', 'meta_keywords']
class OfferAdmin(admin.ModelAdmin):
list_display = ['preview_image','title','tags', 'publish']
list_display_links = ['title']
list_filter = ['tags']
inlines = [TaskOfferAdmin, ]
fields = ['title', 'discription', 'cover', 'tags']
class UserOfferAdmin(admin.ModelAdmin):
pass
admin.site.register(UserOffers, UserOfferAdmin)
admin.site.register(Offer, OfferAdmin)

正在运行python manage.py migrate并且出现错误，应该有一个*.sqlite3在 DATABASE 上指定的路径上创建的文件您的 settings.py 中的 key 文件。
示例:

'NAME': os.path.join(BASE_DIR, 'base_site.sqlite3'),
}
}
我的 Sqlite 数据库文件名是 base_site.sqlite3并创建于 BASE_DIR项目的。
要遵循的步骤:
