<p>我们不是来为您编写站点代码的,但是我相信10gen的本教程可能会帮助您:<a href="http://docs.mongodb.org/manual/tutorial/write-a-tumblelog-application-with-flask-mongoengine/" rel="nofollow noreferrer">http://docs.mongodb.org/manual/tutorial/write-a-tumblelog-application-with-flask-mongoengine/</a>。</p>
<p>既然你不懂Python(像我一样),我就给你几个建议:</p>
<ul>
<li>看教程</li>
<li>搜索谷歌</li>
<li>了解你的问题的本质,并把它分解成你能解决的小部分。然后在你理解了这些小部分之后,把它构建成完整的上下文。</li>
<li>当人们传授知识时,这是一种感恩的表示。</li>

<p>正如另一个SOer在上面所说的,这是非常主观的,所以我将给您发送一些链接,这些链接可能支持,也可能不支持MongoDB的使用,但它们将帮助您不落入旅行车的陷阱:</p>

<p>如果你真的要征求我的意见,而且只征求我的意见:</p>
<ul>
<li>更容易整合</li>
<li>它回到了基础,上面没有重量</li>
<li>它还很年轻,很有前途</li>
<li>10gen似乎对项目应该朝哪个方向发展有很好的想法,他们在这方面做得最好。</li>
