Please share option "classPath" on "classPath" and "classUrl", does not always correspond to the physical location of the folder path RL. For example I have it so: "classUrl": "/ direct",
"classPath": "/ app / direct"

Using Architect example. Watching in mongo with

use extdirectnode
db.tasks.find()

Every time bringing up Add Task button adds an extraneous task (as you can see in Mongo). Further all those tasks have a Mongo generated _id ObjectId as well as an id of 0. Which one could be willing to overlook if it weren't the issue that on load of the gridpanel one sees only a single (the most recent?) of those tasks, as if all of them having id 0 prevents the additional tasks from showing,

Hello Juris,

Sorry if this is not the right place to put this, but i could not find another spot.

Thank you for the examples. I got it up and running yesterday, but I have a question / suggestion.

Wouldn't it be better to use uuid's instead of auto increment for the id?

For the MySql example i changed the code in DXToDoItem.js so it creates a uuid using the node-uuid lib and use this uuid (params['id']) for the second query.
Next to that, change MySql column structure to match uuid (e.g. char(36)). Clientside id becomes string instead of int. Works perfect for me.

var table = 'todoitem';
var db = global.App.database;
var uuid = require('node-uuid');

var DXTodoItem  = {
    create: function(params, callback){
        var conn = db.connect();
        //delete params['id'];
        params['id'] = uuid.v4();

        conn.query('INSERT INTO ' + table + ' SET ?', params, function(err, result) {

            if (err) throw err;

            conn.query('SELECT * FROM '  + table + ' WHERE id = ?', params['id'], function(err, rows, fields) {
                db.disconnect(conn); //release connection
                callback({
                    success: true,
                    data: rows[0]
                });
            });


        });
    },

Thanks again!

I think there isn't a WHERE in the MySQL implementation, which means it cannot support filtering. Did I think correctly?

I'd like to implement complete CRUD support for MongoDB, and I am looking at your MySQL as an example.

Is that the last item missing for complete CRUD according to Ext.Direct?

As side thought: Would that same code that does filtering also take care of read finding by id, if that is in use anywhere in Ext JS? I don't know whether that is a feature of read use by Ext JS and Ext.Direct, I am just thinking it would be the same kind of WHERE.

Same as last time, if you lead for MySQL, I will follow for MongoDB. This time I should be faster because this is a smaller step and we are actually using it.

Because if I (anyone) clone(s) it or fork(s) it and the resulting directory or repo lives at top level with other repos it is too generic "code-examples".

Hi! I'm brand new to sencha/extjs and have difficulties following the instructions...

I've done the following (on win 8.1):

• Installed Sencha Cmd v5.1, it's in my path
• Downloaded extjs 4.2
• Ran sencha generate app DemoExtJs ..\DemoExtJs within the ext-4.2.1.883 folder
• Cloned this repo
• Replaced the ext folder in extdirect.examples\client\DemoExtJs with the generated one

Running sencha app refresh in extdirect.examples\client\DemoExtJs results in:

Sencha Cmd v5.1.1.39
[INF] Processing Build Descriptor : default
[ERR]
[ERR] BUILD FAILED
[ERR] com.sencha.exceptions.ExNotFound: Required property file [path]\extdirect.examples\client\DemoExtJs\.sencha\app\development.defaults.properties does not exist

com.sencha.exceptions.ExNotFound: Required property file [path]\extdirect.examples\client\DemoExtJs\.sencha\app\development.defaults.properties does not exist

Should I use another combo of framework and sencha cmd?
Or have I simply misread the instructions? (they are a bit vague for someone not familiar with extjs)
Thanks

To set something in a session, or to read from it I need to get to req.session, means need to get to req.

How to do that inside e.g. DXFormTest.js or DXTodoItem.js?

You probably know this kind of situation, so I'll keep it short: Apparently at time of autoLoad the DirectAPI isn't available yet, so it fails (nasty stuff in console log saying can't do that API), and the spinning Loading indicator prevents anything from being done in UI. After I switched off (got rid of) autoLoad for Tasks store there was no more nasties in console log, no more spinning Loading indicator, and I was able to click Add Task and add a task, which I then saw in MongoDB. Obviously though didn't load existing data on startup, but you probably know where you want to trigger that (what event).

I am recognizing that in directory direct multiple classes like DXTodoItem.js could inherit a lot of common code from a generic class. I see the need clearly for an example with MongoDB I am working on.

Do you, does anyone, have a suggestion, from experience, with Node.js, in this context, which kind of inheritance to use?

We seem not to find an easy way to open this as a project in Sencha Architect 3 so far.

Any advice or additional file needed?

Got this working with Sencha Cmd. But now a colleague asks questions so I thought "let's open this with Sencha Architect 3" so we can "see" how the Store is configured, so she can do the same (using Ext.Direct for store) in her from scratch project in Sencha Architect 3.
