我正在使用Flask和PyMongo创建一个爱好应用程序,以在浏览器中呈现mongodb记录。
这是维基百科编辑的数据库,记录如下:
{
"_id" : ObjectId("4ff1c0d0dec94126a2000000"),
"image" : "http://upload.wikimedia.org/wikipedia/commons/thumb/b/b6/Us_declaration_independence_signatures.jpg/350px-Us_declaration_independence_signatures.jpg",
"unvandalism" : "<div>:<span class=\"diffchange diffchange-inline\">53</span>. [[Arthur Middleton]]</div>], [<div>:<span class=\"diffchange diffchange-inline\">54</span>. [[Button Gwinnett]]</div>], [<div>:<span class=\"diffchange diffchange-inline\">55</span>. [[Lyman Hall]]</div>], [<div>:<span class=\"diffchange diffchange-inline\">56</span>. [[George Walton]]</div>",
"delta" : 0,
"date" : ISODate("2012-07-02T00:44:57.781Z"),
"offender" : "24.119.187.78",
"reverter" : "Chillin411",
"anon" : true,
"vandalism" : "<div>:<span class=\"diffchange diffchange-inline\">54</span>. [[Arthur Middleton]]</div>], [<div>:<span class=\"diffchange diffchange-inline\">55</span>. [[Button Gwinnett]]</div>], [<div>:<span class=\"diffchange diffchange-inline\">56</span>. [[Lyman Hall]]</div>], [<div>:<span class=\"diffchange diffchange-inline\">57</span>. [[George Walton]]</div>",
"time" : 1341189897781,
"diff_url" : "http://en.wikipedia.org/w/index.php?diff=500257674&oldid=498121414",
"date_str" : "Mon, 02 Jul 2012 00:44:57 GMT",
"page" : "Signing of the United States Declaration of Independence"
}
我希望能够创建一个与记录相关联的文本字段,以允许用户向该记录添加标记。所以我知道它应该是使用模板中的某个表单的更新/ upsert POST操作。但是我在实现这一目标的基本方法上已经陷入困境,因为获取每条记录的上下文并说“在此处记录此记录并更新用户已提交标记并单击提交的标记”。我在想它。
在现有设置的基础上实现这一目标的最实用方法是什么?

不确定您是否正在寻找pymongo help,MongoDB help或Flask help。
也许这段代码会帮助你...
from flask import request
tags = request.form.get('tags', []) # Where tags is a list of new tags
mongo_collection.update(
{'_id': ObjectId('4ff1c0d0dec94126a2000000')},
{'$pushAll': {'tags': tags}},
)
