    <p>I have a dgrid that has editable date fields. Above it, I have a "Save" button that calls <code>grid.save</code>. When I hit the button, it makes an XHR request back to the store's target, but does not provide any data back to the server for me to save (i.e. POST is empty). Right now it is hardwired to query item id 1900, as you can see in the code below.</p> <p>Here is how the store is initiated:</p> <pre class="lang-javascript prettyprint-override"><code> var store = new JsonRest({ target: "/safari/resources/1900/calendarObjects/", sortParam: "sort", idProperty: "id", properties: { startDate:{ format: "date-time" }, endDate:{ format: "date-time" } } }); </code></pre> <p>And here is the grid:</p> <pre class="lang-javascript prettyprint-override"><code> var grid = new declare([OnDemandGrid, dgridEditor, Keyboard, Selection, DijitRegistry])({ store: store, query: {responseType: "json" }, bufferRows: 40, loadingMessage: "Loading...", columns: [ {field: "oid", label: "Object ID"}, dgridEditor({field: "startDate", name: "Start Date", editorArgs: { selector: 'date', datePattern: 'yyyy-MM-dd', locale: 'en-us' }}, DateTextBox), dgridEditor({field: "startTime", name: "Start Time"}, TimeTextBox, "click"), dgridEditor({field: "endDate", name: "End Date"}, DateTextBox, "click"), dgridEditor({field: "endTime", name: "End Time"}, TimeTextBox, "click"), {field: "endDateOid", label: "End OID"} ], }, "grid"); </code></pre> <p>The save button looks like this:</p> <pre class="lang-javascript prettyprint-override"><code>registry.byId("saveButton").on("click", function (){ grid.save(); }); </code></pre> <p>Like I said, after I click "save," a new XHR request fires, but if it is sending any data back to the server, I'm not sure where it is going. I had my backend print up all of the HTTP headers it received and didn't see anything.</p> <p><strong>UPDATE (January 2, 2013):</strong> Upgraded server backend to use a traditional RESTful URL, which seems to make Dojo slightly happier, but it still is using <code>GET</code> instead of <code>PUT</code> and fails to actually send anything to save.</p> <p><strong>UPDATE (January 5, 2013):</strong> Is there any reason why JsonRest would call GET before calling PUT? I'm wondering if my program needs to return certain data before the program is willing to go do the PUT (and thus the problem isn't the GET but whatever comes next)... But, this is entirely speculation. I've reached a dead end. </p>

    1. COI updated the target to be a proper RESTful URL. It requests the appropriate object ID when contacting the server to save changes, but it doesn't actually send the changes and it uses GET rather than PUT.

    2. COThe other thing I have noticed is that it always tries to GET id number 1 and not the actual id of the item. I have two id's in my JSON file -- a consecutive one for sorting the table and the unique ones I use to manage items in the database. I would like for Dojo to manipulate the system using the latter, though I have found dgrid was unhappy when I told the system to use those ids since they are not consecutive.

    3. COSomeone just edited this post, which reminded me I never found a solution. Any suggestions?

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.

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