joomla module calls components model method

Question

What is the way to call components model method in a joomla module. I know there is a helper file inside of custom module and that should do the job, but how they do that?

Answer 1

It doesn't matter if you do it in the helper file or in the main file. The helper file is just a nice place to stuff away this kind of code :)

To call the model you need to include it first since it's not autoloaded. That means usually using something like require_once('components/com_content/models/article'). After that you can instantiate the class with $class = new ContentModelArticle and call the method $item = $class->getItem(). That should at least work in theory :)
