    <p>I've been trying to implement a simple subgrid within jqgrid to show line items for an invoice. I finally got the subgrids to populate but each subgrid is showing the same list of line items, which is actually all of the entries in the data set.</p> <p>I'm not quite sure how to debug this but here are some of my potential ideas-</p> <ul> <li><p>Is it a problem with the way the json store is (not) responding to the GET queries?</p></li> <li><p>Is it because nowhere I define what field within the subgrid data is the "foriegn key" so to speak.</p></li> <li><p>Do I need the subGridUrl to point to json data with only the appropriate data (not every line item)</p></li> </ul> <p>Example JSON for line items: order_id points to the id of the order</p> <pre><code>{ "total": 1, "records": 6, "rows": [ { "description": "PART X", "order_id": 2, "qty": 5, ... more fields ... "id": 1 }, ... more ... ], page: 1 } </code></pre> <p>JSON for main grid items:</p> <pre><code>{ "total": 1, "records": 2, "rows": [ { "order_no": 2, ... more fields ... "id": 2 }, ... more ... ], page:1 } </code></pre> <p>Applicable parts of my jqqrid script:</p> <pre><code>jQuery("#mygrid").jqGrid({ ... cosmetic stuff for main grid ... url: "/my_json_url/", datatype: "json", colNames:['Order',...], colModel:[ {name:'order_no', index:'order_no'}, ... ], jsonReader: { repeatitems:false, root: "rows", page: "page", total: "total", records: "records", cell: "", id: "id", subgrid: {root: "rows", cell:"", repeatitems: false} }, prmNames: {subgridid: "order_id"}, subGrid: true, subGridUrl: "/json_url/to_line_items/", subGridModel: [{ name : ['qty','description'], width: [100,100] }] })navGrid(some options); </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.
