    <p>I have two schemas that look like this: </p> <pre><code>var ToolBoxSchema = new Schema({ description: String, tools: [{type: ObjectId, ref: 'Tool'}] }); var Tool = new Schema({ name: String, model: String, }); </code></pre> <p>Let's say I have a new <code>ToolBox</code> that has a set of <code>Tools</code>. I have an array of <code>Tools</code> and would like to use the create method from mongoose to save these tools and then add a reference to the ToolBox.tools array for each tool. </p> <pre><code>var toolBoxModel = mongoose.model('ToolBox', ToolBoxSchema); var toolModel = mongoose.model('Tool', ToolSchema); var toolbox = new toolBoxModel(); var tool = new toolModel(); var toolsArray = getTools(); </code></pre> <p>Assume getTools() returns an array of tools with X number of elements. Ex: [{name: "screwdriver", model: "craftman 3000"}, {name: "drill", model: "black and decker"}]</p> <p>When I call the model's create method, how can I get a list of all of the documents that were saved?</p> <p>The example in the mongoose api docs shows each saved document being passed in as a parameter to the callback function, but if the number of elements in the array is different every time then I don't know how to get the id's of all the saved elements in the array. </p> <pre><code>var array = [{ type: 'jelly bean' }, { type: 'snickers' }]; Candy.create(array, function (err, jellybean, snickers) { if (err) // ... }); </code></pre> <p>Is there a way to get back an array of all the saved documents ...maybe something like this:</p> <pre><code>var toolsArray = [{name: "screwdriver", model: "craftman 3000"}, {name: "drill", model: "black and decker"}]; tool.create(toolsArray, function (err, arrayOfToolDocs) { if (err) { throw err; } for (var i = 0; i &lt; arrayOfToolDocs.length; i++) { toolbox.tools.push(arrayOfToolDocs[i].id); } toolbox.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.
