更新＃3
最后更新： 12月17日上午10点
状态： / strong>仍然未解决，可以使用一些帮助
- 我更新了此帖子顶部的错误消息，是的，错误信息很短。
- 除了名为博客的应用程序之外，我还附带了实际项目的url.py。
- 修正了迁移不同步
- 终端不再有错误
- 问题可能在模型中，views或urls.py

更新：确定迁移问题已被移除。
更新2：ok，所以没有管理网址格式
你的在您的主要urls.py中导入博客网址？您可以通过模式r'^ admin /'和r'^ markdown /'作为博客条目匹配所有内容。
现在你的请求是/ admin，由于最后没有一个/（斜杠），而不是匹配第一个模式，它与最后一个匹配：r' ^（？P\S +）$。所以现在，它会使用一个名为admin的小插件来查找博客条目，找不到一个，因此返回404，非常清楚。 （下一次不要犹豫，在问题中包括:)
我还希望请求/ admin /将导致一个管理页面，因为它会匹配r'^ admin /'，因为尾随/
更好的做法是避免主要url和应用程序特定URL之间的冲突通过以下方式对您的博客进行子URL排序：
url（r'^ blog /'，include（' urls'，namespace =blog）），

更新前：
也许您尝试使订单字段具有唯一性，其中唯一的值。你尝试删除整个数据库并重建它吗？这将是我的第一个建议。
似乎在sqlite中有一些怪癖，我从来没有使用它。我也建议尝试使用比较成熟的东西，比如postgresql或者mysql。
I currently cannot log into my admin in Django, I get a 404 page.

No Blog entry found matching the query
UPDATE #3
Last Updated: Dec 17, 10 AM
Status: Still unresolved, could use some help
- I've updated the error message at the top of this post, and yes, the error message is short.
- I've included the url.py for the actual project, in addition to the app called blog.
- Fixed the migrations being out of sync
- There is no longer an error in the Terminal
- The problem might lie somewhere in models, views or urls.py

Update: ok the migration problem has been moved out of the way.
Update 2: ok so it isn´t lacking the admin url pattern
What is the case with your importing the blog urls in your main urls.py? You match everything that falls through the patterns r'^admin/' and r'^markdown/' as a blog entry. Now your request is "/admin", and because of the lacking of a "/" (slash) at the end, in stead of being matched against the first pattern, it is matched against the last one: r'^(?P\S+)$'. So now it looks for blog entry with a slug called "admin", and fails to find one, and hence returns 404 with a very clear discription. (next time don´t hesitate to include that in the question :)
I expect also that requesting "/admin/" will result in an admin page, because it would get matched against r'^admin/', because of the trailing /
better practice is to avoid conflicts between main urls and app specific urls by sub-url'ing your blogposts somewhat like this:
url(r'^blog/', include('blog.urls', namespace="blog")),
https://docs.djangoproject.com/en/dev/intro/tutorial03/#namespacing-url-names
before update: Maybe you tried to make the order field unique after having non-unique values in it. Have you tried removing the whole database and rebuilding it? That would be my first suggestion.
It seems like there are some quirks in sqlite, I never use it basically. I would suggest also to try using something more mature like postgresql or mysql.
