Question

I’m using a DOJO JsonRestStore. I modify fields in the object.

What would be the proper procedure for persisting the modified object back to the datastore and REST service?

Update: Removed info about grid as it was not part of the problem.

Answer 1

Apparently I had assumed that the returned item would be synchronized with the datastore. It doesn’t appear so and must be updated manually using:

store.setValue(item, field, value);

I was also hoping for a command equivalent to JPA merge. If you overwrite the prior object with:

store.newItem( updatedVersionOfItem );

and the item has the same unique id, it will overwrite the old item similar to merge.

Does anyone know if there some sort of a factory that will create getters and setters for an item that will call store.setValue() for each field?

I imagine it would be something like the following:

var wrappedItem = itemWrapperFactory.createWrapper( item, store );
...
//Some where in createWrapper(...), this is just the concept
for (var itemField in itemFieldList)
this.__defineGetter__( itemField[index] , function(val){
    store.setValue(item, itemField[index], val);      
});

I am consider writing my own as its a neat piece of architecture.
