    <p>I use mongoengine for mongodb in django.</p> <p>but.. mongoengine fields (like StringField) makes me build up schema toward the way that I don't want. I mean, it strictly insists that I pre-write key name before I do know what it will be. for example...</p> <p>in case that I do not know what key name will be put into database...</p> <pre><code>&gt; for(var i=0; i&lt;10; i++){ ... o = {}; ... o[i.toString()] = i + 100; ... db.test.save(o) ... } &gt; db.test.find() { "_id" : ObjectId("4ed623aa45c8729573313811"), "0" : 100 } { "_id" : ObjectId("4ed623aa45c8729573313812"), "1" : 101 } { "_id" : ObjectId("4ed623aa45c8729573313813"), "2" : 102 } { "_id" : ObjectId("4ed623aa45c8729573313814"), "3" : 103 } { "_id" : ObjectId("4ed623aa45c8729573313815"), "4" : 104 } { "_id" : ObjectId("4ed623aa45c8729573313816"), "5" : 105 } { "_id" : ObjectId("4ed623aa45c8729573313817"), "6" : 106 } { "_id" : ObjectId("4ed623aa45c8729573313818"), "7" : 107 } { "_id" : ObjectId("4ed623aa45c8729573313819"), "8" : 108 } { "_id" : ObjectId("4ed623aa45c872957331381a"), "9" : 109 } </code></pre> <p>[addition]</p> <p>as you can see above, key is very different from each other.. just assume that "I do not know what key name will be put into document as key ahead of time</p> <p>as dcrosta replied.. I am looking for a way to use mongoengine without specifying the fields ahead of time.</p> <p>[/addition]</p> <p>How can I do the same thing through mongoengine? please give me schema design like</p> <pre><code>class Test(Document): tag = StringField(db_field='xxxx') </code></pre> <p>[addition]</p> <p>I don't know what 'xxxx' will be as key name.</p> <p>sorry.. I'm Korean so my english is awkward. please give me your some knowledge. Thanks for reading this.</p> <p>[/addition]</p>

    2. COI'm not sure exactly what you're asking to do here. You can use `db_field` to use a different name in the database from the name of the attribute on your Python class, but you will still only have one field in this case. Are you looking for a way to use Mongoengine without specifying the fields ahead of time?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
