MY_Model Base CRUD Model - El Forum - 12-17-2009

I want to make a suggestion for MY_Model.
Please, add $limit and $offset to the functions that get many rows (get_many_by and get_all) as most times I have to write custom models to limit the amount of data and from where it gets fetched. I also need offset for pagination purposes.

Thanks in advance.

Update 1.1.1
A limit() method. Call it before any methods to add a LIMIT clause to your query. Takes two parameters - the limit integer and an optional offset.

errrm, sorry. Thank you so much for your fast response and fast action.

This one just popped into my head one hour after I made my last post and I am just checking this thread now. An order_by method will be handy too. It should handle strings or multiple array containing fields with which the result set will be ordered and the order_by value (asc, desc, random).

e.g. $this->product->order_by('sort = asc, date = desc')->get($id); //string
and $this->product->order_by(array('sort' => 'asc', 'date' => 'desc')->get($id); //array

Following your limit() method in the latest release, I've got something working on my end. Just thought I should let you know.

It'll be my last request though for this library though. Wink

Thanks for the simple but great libraries. They are lifesavers. Smile

Quote:Tutorial
I’ve written a tutorial that takes a reasonable look at the functionality provided by the entire class, as well as my MY_Controller Controller System on my delightful blog. Check it out and feel free to leave a comment.

Your website has changed. Can you give an update on where your tutorial is for your MY_Model please.

I'm trying to learn more about it. Specifically:

Code:
/**
     * Runs the before create actions.
     *
     * @param array $data The array of actions
     * @return void
     * @author Jamie Rumbelow
     */
    private function _run_before_create($data) {
        foreach ($this->before_create as $method) {
            $data = call_user_func_array(array($this, $method), array($data));
        }
        
        return $data;
    }
    
    /**
     * Runs the after create actions.
     *
     * @param array $data The array of actions
     * @return void
     * @author Jamie Rumbelow
     */
    private function _run_after_create($data, $id) {
        foreach ($this->after_create as $method) {
            call_user_func_array(array($this, $method), array($data, $id));
        }
    }


Thanks.

Jamie,

In your future versions, will you be allowing for joins?

I answered my question by rereading your first post!

I'm getting this error using MY_Model

Quote:Call to undefined method MY_Model::MY_Model() on line 18

which is

parent::__construct();


Here's my code

Code:
class Countries_model extends MY_Model
{

    function __construct()
    {
        parent::__construct();
        $this->table = 'countries';
    }

    
    /**
     * Get Countries
     *
     * @param    int
     * @return    array
     */
    function get_all_countries($limit, $offset)
    {
        $this->db->select("*, DATE_FORMAT(created, '%b. %d,%Y') as created", FALSE);
        $this->limit($limit, $offset);
        return $this->get_all();
    }
    
    
    /**
     * Count Countries
     *
     * @param    int
     * @return    array
     */
    function count_all_countries()
    {
        return $this->count_all();
    }
    
}

Hey megabyte,

Can you show me the controller code you're using to load it?

Hmm, I think I know what's going on here. Hang on. I'll edit when a fix has been made.

EDIT Done. It's on the GitHub repo, check it out straight from master.
