[OPEN-126] Model.destroy method doesn't exist

[abierbaum]

I have been trying to follow along the Model documentation to test a RestProxy that supports GET, PUT, POST, DELETE. I got all the way up to delete, but I can't figure out how to delete a model item.

I tried the example code from the Model class, but it says to call 'user.destroy()' (where user is a Model item).

Problem is, it doesn't look to me like that method exists.

Can anyone confirm how to delete a model item once it is created?

you right abierbaum that method is missing right now. on the bright side it's a known issue and should make it into a point release soon. for now you'll have to grab the proxy and execute a delete operation on there instead.

This still seems to be missing, or am I missing something ?

I ran into the same problem too. Seems crazy that no one caught this.

Also, call destroy on the proxy is not a very helpful comment as well as you actually have to fake your own operation dictionary. The following code worked for me, YMMV:

this.myModel.getProxy().destroy(new Ext.data.Operation({action: 'destroy', id: this.myModel.getId()}));

I ran into the same issue: destroy on Model not implemented.

You may use the following override (based on the save method), until it is fixed:

Ext.override(Ext.data.Model, {
        destroy: function (options) {
            var me = this,
            action = 'destroy';

            options = options || {};

            Ext.apply(options, {
                records: [me],
                action: action
            });

            var operation = new Ext.data.Operation(options),
            successFn = options.success,
            failureFn = options.failure,
            callbackFn = options.callback,
            scope = options.scope;

            var callback = function (operation) {

                if (operation.wasSuccessful()) {


                    if (typeof successFn == 'function') {
                        successFn.call(scope, record, operation);
                    }
                } else {
                    if (typeof failureFn == 'function') {
                        failureFn.call(scope, record, operation);
                    }
                }

                if (typeof callbackFn == 'function') {
                    callbackFn.call(scope, record, operation);
                }
            };

            me.getProxy()[action](operation, callback, me);

            return me;
        }
    
    })

Thanks for the report. I have added this into our tracker.

Luc... I'm using the override that you post for the detroy method, but I can get the return of the method (if it was successful or not).

Does anyone know how to do this?

Example:

rec.destroy({
      success : function() {
             // something here (nothing happens here)
      },
      failure : function() {
            // something here (nothing happens here)
      }
});

Is this seriously still an open issue (the "D" in "CRUD" missing?????) or is this entire thread missing something obvious? Anyway - I can confirm that the 1.1.1 docs don't match up with the actual code (standard) and that there's no way to delete a model in sencha 1.1.1. Which is still the active release. A full year after this bug was posted.
