How can I access a model from a controller using laravel4?

So far I have my controller:

<?php
class GatewayController extends BaseController {

public function getContentAll()
{
    $content = Content::getContentAll();
    return $content;

}

And my model:

<?php

class Content extends Eloquent {

    protected $table = '_content';

    public function getContentAll(){

        return 'test';
    }

But I get:

Whoops, looks like something went wrong.

Answer 1

Firstly, Eloquent handles the returning of a model collection. You do not need to handle this yourself. So your model should simply look like this:

class Content extends Eloquent {

    protected $table = '_content';

}

You can then simply get all your content using this:

$content = Content::all();

EDIT:

If you want to do stuff with the data in your model, try this:

class Content extends Eloquent {

    protected $table = '_content';

    public function modifiedCollection()
    {
        $allContent = self::all();
        $modifiedContent = array();

        foreach ($allContent as $content) {
            // do something to $content                  

            $modifiedContent[] = $content;
        }

        return $modifiedContent;
    }  
}

This should then work:

$content = Content::modifiedCollection();

Answer 2

Instead of this:

$content = Content::getContentAll();

Try this:

$content = Content->getContentAll();
                  ^^

Or declare your function as static , like so:

public static function getContentAll(){

    return 'test';
}

UPDATE : if you don't want to have a static function , you should instantiate your class in order to call non-static functions:

$c = new Content();
$content = $c->getContentAll();
