codeigniter modular extensions

I'm trying to i开发者_Python百科mplement modular extensions into a codeigniter 2 setup but am having a few problems. I followed the installation instructions on the wiki and everything was working fine. Then I started to play around a bit and try and use it. All I did was create a new module called users with the required folders and added a model class called users_m. I then tried to load this from my welcome module controller. According to the wiki this should be very straightforward. I simply added this line

$this->load->model('users/users_m');

to the constructor of my welcome controller.

Unfortunately at this point I get the white screen of death.

So I tried something else. This time I removed the load model line and added

$this->output->enable_profiler(TRUE);

This time I got the welcome page displayed and I got the profiler, but at the top of the page I got this error:

A PHP Error was encountered

Severity: Notice

Message: Undefined property: CI::$profiler

Filename: MX/Loader.php

Line Number: 145

I don't know if these two tries are related or not, but there's obviously something not right with my setup. Could someone point me in the right direction?

If you accessing the model from the controller in the same module, you can load it using just:

$this->load->model(‘user_m’);

You only have to do $this->load->model(‘module/model_name’); when your cross loading between modules.

Just to make sure, your model is located here right?

application/modules/users/models/users_m.php

As for the profiler error:
1) Have you done installation step 5 and put the Modular Extensions core files into application/core?
2) Do you have the latest version of HMVC? There have been updates to mx/loader.php in the last couple days.

Ps. great tutorial on HMVC: http://net.tutsplus.com/tutorials/php/hvmc-an-introduction-and-application/

if you have folder structure like:

application/
           modules/
                  users/
                       models/
                             users_m.php

then use this to call modelsin you controller

$this->load->model('users/users_m','',TRUE);
