    <p><strong>EDIT 1</strong></p> <p>Actually after further investigation it seems that MogoDB is only holding the most recent 7 records, is this to do with the way i am sending the objects to mongoose, is it overwriting them?</p> <p>I removed all reference to TTL/Timeout and i only ever see the most recent 7 objects (there are 7 different objects to be stored, but with multiple values over time).</p> <p>Help greatly appreciated!</p> <p>Thanks</p> <p>Gareth</p> <p>This seems simple enough in the docs, but i can't get it to work.</p> <p>I have created a template which looks like this:</p> <pre><code>var trackingSchema = new mongoose.Schema({ VehicleID: {type: String, min: 0}, Label: {type: String, min: 0}, RegNumber: {type: String, min: 0}, VehPosDateTimeUTC: {type: String, min: 0}, Latitude: {type: String, min: 0}, Longitude: {type: String, min: 0}, Heading: {type: String, min: 0}, SpeedKPH: {type: String, min: 0}, OdometerKM: {type: String, min: 0}, SpeedMPH: {type: String, min: 0}, OdometerMiles: {type: String, min: 0}, EventCode: {type: String, min: 0}, GpsStrength: {type: String, min: 0}, Owner: {type: String, min: 0}, DriverName: {type: String, min: 0}, DriverID: {type: String, min: 0}, EventCodeId: {type: String, min: 0}, EventType: {type: String, min: 0}, createdAt: { type: Date, default : Date.now, expires: '1d'}, }); </code></pre> <p>However upon creating the objects through mongoose, into the Mongolab set the records are only kept for a maximum of 1 minute.</p> <p>I have tried other variants of the createdAt line also, such as:</p> <pre><code>createdAt: { type: Date, default : Date.now, expires: 6000 } </code></pre> <p>Now i thought this could be timezone related, but i'm not really sure how to resolve that?</p> <p>Here is the code i am using to commit the object to mongoose:</p> <pre><code>// Creating one vehicle record. var vehicleData = new trackingRecord ({ VehicleID: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].VehicleID[0], Label: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].Label[0], RegNumber: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].RegNumber[0], VehPosDateTimeUTC:responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].VehPosDateTimeUTC[0], Latitude: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].Latitude[0], Longitude: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].Longitude[0], Heading: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].Heading[0], SpeedKPH: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].SpeedKPH[0], OdometerKM: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].OdometerKM[0], SpeedMPH: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].SpeedMPH[0], OdometerMiles: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].OdometerMiles[0], EventCode: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].EventCode[0], GpsStrength: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].GpsStrength[0], Owner: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].Owner[0], DriverName: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].DriverName[0], DriverID: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].DriverID[0], EventCodeId: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].EventCodeId[0], EventType: responseJSON.VehPosResponse.position_list[0].CVehiclePos[i].EventType[0] }); // Saving it to the database. vehicleData.save(function (err) {if (err) console.log ('Error on save!')}); </code></pre>

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.
