Calling a model from another model?

[eluser]mattalexx[/eluser]
Thanks for the good discussion. I see now that there is absolutely no best practice when it comes to underscores; that it's just personal preference. Anyway, back to the original purpose of this post (accessing a model from another model) ...

I'm using the following code and loading the model using this (it seems to work):

Code:

$this->load->model('item_image_model');
print class_exists("Item_image_model")? "loaded" : "not loaded"; // loaded

So I access methods this way:

Code:

$select = Item_image_model::get_select();

Using this syntax isn't mentioned in the docs to the best of my knowledge, so I wanted to run it by you and see if there is a better way to do it.
