RE: [fw-mvc] How to correctly use Zend_Dojo_Data

Thank you!

I've got it working now, but have a question about the "item must contain a column matching the currently set identifier". It doesn't matter what I use as my identifier value, as long as it's one of the keys in my associate array? Or is this to be thought of more like a primary key in the data set? Sorry - I'm simultaneously learning Dojo at the same time learning the Dojo View Helpers.

Regards

When passing an array, it needs to be an array of _associative_ arrays.
That's where the "item must contain a column matching the currently set
identifier" exception comes in -- if you don't use associative arrays,
then it won't work for dojo.data.

For objects, we either call the object's toArray() method or cast it to
an array using get_object_vars() -- so these should work fine.

As an example of something that would work:

$items = array(
array('name' => 'foo', 'title' => 'Foo'),
array('name' => 'bar', 'title' => 'Bar'),
azray('name' => 'baz', 'title' => 'Baz'),
);

$data = new Zend_Dojo_Data('name', $items);
echo $data->toJson();
