DirectProxy example needed

[sidamos77]

I have searched the internet up and down to find an ExtJs DirectProxy example. Even one for 3.x would be great.

I need explanation for instance, how to code the directFn function and what directFn.directCfg.method is.

I got a directFn working, but what are the parameters that I get? One seems to be callback function. What parameters does this need?

There is severe lack of documentation about this, I guess.

Thanks!

There are several direct examples in the b1 download. Under /direct

Thanks for the pointer. I had searched in examples, but did not find it, because I only searched for "DirectProxy" instead of "type: 'direct'".

In those examples, what is that "TestAction"? I cannot find it declared anywhere.

did you looked in examples/direct? Everything is in, TestAction is the direct method in php.

[sidamos77]

Thanks. Got it. I had only looked in the .js files.

I am no php expert. TestAction seems like a server side class that can be remotely called by js, I guess.

But what about directFn.directCfg.method? Or even directCfg? I can't find that in the examples.

It's an internal thing, you shouldn't touch it.

OK, but I get an exception from ExtJs Beta 1 at line 38490 of ext-all-debug.js:

method = fn.directCfg.method;

fn.directCfg is undefined.

    var getData = function() {
      console.info('DirectProxy callback!');
      console.info(arguments);
    }
    var bufferStore = new Ext.data.BufferStore({
        id: 'bufferStore',
        pageSize: 200,
        model: 'Artikel',
        remoteSort: true,
        proxy: {
            type: 'direct',
            directFn: getData,
            model: 'Artikel'
        }
    });

[...]

    bufferStore.guaranteeRange(0, 199);

Because you haven't set it up properly. The directFn isn't a regular function, have a look through the examples.

Hmm, I don't see this special setup. Any more pointers would be greatly appreciated.

OK, I finally found this page, which explains some things:
http://www.sencha.com/blog/ext-js-30...-for-everyone/

However, this page (Direct specs) does not exist (anymore):
http://www.sencha.com/products/extjs/direct.php

I am beginning to understand what ExtJs Direct is and I think now, that this does not fit our needs, because we already have a remoting solution: DWR

So, the question is: How can I get a callback from a Ext.data.BufferStore, when it needs data, so that I can call an existing DWR method to fetch the data?
