    <p>I am trying to pull/remove values from an array (subdocument).</p> <p>Example doc:</p> <pre><code>{ _id: 5150a1199fac0e6910000002, name: 'some name, items: [{ id: 23, name: 'item name 23' },{ id: 24, name: 'item name 24' }] } </code></pre> <p>I have the doc in memory as I pulled it from mongo already. I am trying:</p> <pre><code>var left = object.items.pull({id: 24}); console.log(left) </code></pre> <p>Outputs:</p> <pre><code>[{ id: 23, name: 'item name 23', _id: 5150a1199fac0e6910000045 },{ id: 24, name: 'item name 24', _id: 5150a1199fac0e6910000002 }] </code></pre> <p>So looks like I already have a problem. The array returned from the pull call should be whats left in the array after the pull . Not sure why it did not pull from the item array. Does this only support pulling by ObjectId ant not user defined fields?</p> <p>I call save:</p> <pre><code>object.save(); </code></pre> <p>Mongoose logs this as the query:</p> <pre><code>Mongoose: mycollection.update({ _id: ObjectId("5150901ac345824a07000002"), __v: 3 }) { '$inc': { __v: 1 }, '$pull': { attachments: { _id: { '$in': [ ObjectId("5150c64d63773efb1f000002") ] } } } } {} </code></pre> <p>This shows why my document is not being removed. The _id of the array item that should be removed is:</p> <pre><code>_id: 5150a1199fac0e6910000002 </code></pre> <p>The item that mongoose is sending to the database to remove is:</p> <pre><code>ObjectId("5150c64d63773efb1f000002") </code></pre> <p>Any ideas what I am doing wrong? I am trying to delete by something other than _id, not sure if that is possible but from the docs looks to be.</p>

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.
