用django做博客，原本是可以用的，博客是項(xiàng)目下的一個(gè)app。后來(lái)我把博客升級(jí)為項(xiàng)目，不再做為為項(xiàng)目下一個(gè)app，做了一些修改。出現(xiàn)了如下錯(cuò)誤。所有頁(yè)面都是類似錯(cuò)誤。Environment:RequestMethod:GETRequestURL:http://127.0.0.1:8000/admin/DjangoVersion:1.6.2PythonVersion:3.4.0InstalledApplications:('django.contrib.admin','django.contrib.auth','django.contrib.contenttypes','django.contrib.sessions','django.contrib.messages','django.contrib.staticfiles')InstalledMiddleware:('django.contrib.sessions.middleware.SessionMiddleware','django.middleware.common.CommonMiddleware','django.middleware.csrf.CsrfViewMiddleware','django.contrib.auth.middleware.AuthenticationMiddleware','django.contrib.messages.middleware.MessageMiddleware','django.middleware.clickjacking.XFrameOptionsMiddleware')Traceback:File"/usr/local/lib/python3.4/dist-packages/django/core/handlers/base.py"inget_response114.response=wrapped_callback(request,*callback_args,**callback_kwargs)File"/usr/local/lib/python3.4/dist-packages/django/contrib/admin/sites.py"inwrapper215.returnself.admin_view(view,cacheable)(*args,**kwargs)File"/usr/local/lib/python3.4/dist-packages/django/utils/decorators.py"in_wrapped_view99.response=view_func(request,*args,**kwargs)File"/usr/local/lib/python3.4/dist-packages/django/views/decorators/cache.py"in_wrapped_view_func52.response=view_func(request,*args,**kwargs)File"/usr/local/lib/python3.4/dist-packages/django/contrib/admin/sites.py"ininner198.returnview(request,*args,**kwargs)File"/usr/local/lib/python3.4/dist-packages/django/views/decorators/cache.py"in_wrapped_view_func52.response=view_func(request,*args,**kwargs)File"/usr/local/lib/python3.4/dist-packages/django/contrib/admin/sites.py"inindex358.model_dict['admin_url']=reverse('admin:%s_%s_changelist'%info,current_app=self.name)File"/usr/local/lib/python3.4/dist-packages/django/core/urlresolvers.py"inreverse480.app_list=resolver.app_dict[ns]File"/usr/local/lib/python3.4/dist-packages/django/core/urlresolvers.py"inapp_dict310.self._populate()File"/usr/local/lib/python3.4/dist-packages/django/core/urlresolvers.py"in_populate285.lookups.appendlist(pattern.callback,(bits,p_pattern,pattern.default_args))File"/usr/local/lib/python3.4/dist-packages/django/core/urlresolvers.py"incallback229.self._callback=get_callable(self._callback_str)File"/usr/local/lib/python3.4/dist-packages/django/utils/functional.py"inwrapper32.result=func(*args)File"/usr/local/lib/python3.4/dist-packages/django/core/urlresolvers.py"inget_callable96.mod=import_module(mod_name)File"/usr/lib/python3.4/importlib/__init__.py"inimport_module109.return_bootstrap._gcd_import(name[level:],package,level)File"/home/caosz/ilemon/views.py"in2.frommodelsimportBlogFile"/home/caosz/ilemon/models.py"in4.classTag(models.Model):File"/usr/local/lib/python3.4/dist-packages/django/db/models/base.py"in__new__92.kwargs={"app_label":model_module.__name__.split('.')[-2]}ExceptionType:IndexErrorat/admin/ExceptionValue:listindexoutofrangemodel.py如下：fromdjango.dbimportmodels#Createyourmodelshere.classTag(models.Model):tag_name=models.CharField(max_length=20)create_time=models.DateTimeField(auto_now_add=True)def__str__(self):returnself.tag_nameclassAuthor(models.Model):name=models.CharField(max_length=30)email=models.EmailField()def__str__(self):returnself.nameclassBlog(models.Model):caption=models.CharField(max_length=50)author=models.ForeignKey(Author)tags=models.ManyToManyField(Tag,blank=True)content=models.TextField()publish_time=models.DateTimeField(auto_now_add=True)update_time=models.DateTimeField(auto_now=True)def__str__(self):returnself.caption+str(self.author)+str(self.publish_time)classMeta:ordering=['-publish_time']update:答案在這里。http://stackoverflow.com/questions/4382032/defining-a-model-class-in-django-shell-fails經(jīng)過(guò)查閱資料：要使用model必須要有app，新建app里面可以沒(méi)有url.py，這樣不影響url簡(jiǎn)短
