    <p>I'm using mongoose for this.</p> <p>My Schema is like this:</p> <pre><code>var UsuarioSchema = new Schema({ email : { type : Email, index : { unique : true}, required : true }, //some other fields, but not required, hopefully, for this sample code test_expira : { type : Date, default : Date.now, index : { expires : 120 }} }); </code></pre> <p>When running on the mongodb shell, this is the information that I believe matters:</p> <pre><code>&gt; db.usuarios.getIndexes() [ { "v" : 1, "key" : { "_id" : 1 }, "ns" : "dbnamehere.usuarios", "name" : "_id_" }, { "v" : 1, "key" : { "email" : 1 }, "unique" : true, "ns" : "dbnamehere.usuarios", "name" : "email_1", "background" : true, "safe" : true }, { "v" : 1, "key" : { "test_expira" : 1 }, "ns" : "dbnamehere.usuarios", "name" : "test_expira_1", "expiresAfterSeconds" : 120, "background" : true, "safe" : true } ] &gt; new Date(); ISODate("2013-06-12T17:41:43.263Z") &gt; db.usuarios.findOne({email : 'someemail@gmail.com'}); { /* some fields go in here! */ "email" : "someemail@gmail.com", /* some more fields go in here */ "_id" : ObjectId("51b8b087de01a2ec28000002"), "test_expira" : ISODate("2013-06-12T17:31:51.156Z"), /* some yet more fields go in here */ "__v" : 0 } </code></pre> <p>I haven't tested for how long it goes without getting deleted, but even the docs state only a minute overhead should be what one could expect, but not over 15 minutes for a document that should last only 120 seconds.</p> <p>I'm unsure of how to deal with this. Help will be greatly appreciated :)</p> <p>EDIT: Version of mongodb being used is v2.4.4 Version of mongoose is 3.0.3</p>

    1. COlook in mongod log - do you see TTLMonitor thread running every minute?

    2. CObtw, while you are in the logs, make note of what time it is on the server - new Date() gives you shell host time, not server time. It might be earlier on your server.

    3. COI found no evidence of TTLMonitor running. I am unsure of where in the mongodb.conf I should specify this configuration, in case I have to explicitly indicate it is required, I know my current conf file does not indicate it... I thought that just by adding the index the TTLMonitor thread would automatically start running. Also, thank you for your response!

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
