hi all,

i have problem with Datamapper 1.8.0 when using Modular Extensions - HMVC. i tried searching solution from this forum but found nothing (or maybe not enough searching). any help would be very appreciated.

the error:

Code:
Fatal error: Call to undefined method Welcome::get() in D:\public_html\workable\application\modules\welcome\controllers\welcome.php on line 25

controller:

Code:
class Welcome extends MX_Controller {

    /**

     * Class constructor

     */

    function __construct() 

    {

        parent::__construct();

    }

    /**

     * Default action for this class

     */

    function index() 

    {

        $w = new Welcome();

        $w->get();

    }

}

model:

Code:
class Welcome extends DataMapper {

    var $has_many = array();

}

thank you in advanced.

This is PHP.

You can not have two classes with the same class name (in the same namespace). So when you do 'new Welcome()', it creates a new instance of your controller, and not of the model.

I'm trying to find the SQL field type of a given field. I've got code that will search fields using LIKE, however, that's not appropriate for numeric fields.

Does Datamapper store the field type somewhere so I can appropriately change the search? Or is there an easy/elegant way to get a list of field types? I'd like to avoid adding any queries I don't have to.

Currently, field data isn't stored in the object, only the name of the column.

If you want, you can add a feature request at http://bitbucket.org/wanwizard/datamapper/issues, so I can have a look at it when I have the time...

Hi,

i'm trying to create a function which can move up or down nodes by selecting prev or next sibilings with nested sets in Datamapper.

Code:
function move_item_menu()

    {

        $id=$this->input->post('id_item');

        $id_menu=$this->input->post('id_menu');

        $sens=$this->input->post('sens');

        $page=new page();

        $page->select_root($id_menu);

        $page->get_root();

        $page->get_by_id($id);

        $bro=new page();

        $bro->select_root($id_menu);

        $bro->get_root();

        $bro->get_by_id($id); 

        if($sens=='up')

        {

            $bro->get_previous_sibling();

            $page->make_previous_sibling_of($bro);

        }

        elseif($sens=='down')

        {

            $bro->get_previous_sibling();

            $page->make_next_sibling_of($bro);

        }

    }

but unfortunaly it doesn't work.

i use multi tree options
can somebody help me please?

Thanks in advance

The nested_sets extension is still in an expirimental stage, and shouldn't be used in applications unless you're prepared to hunt for bugs (some have already been reported).

I haven't had the time to do that myself, more pressing issues at the moment...

Hi,

from my previous post i solved my issue!

i just saw that it was the make_previous_sibling_of which doesn't work but make_next does what i need so i turned my code into

Code:
function move_item_menu()

    {

        $id=$this->input->post('id_item');

        $id_menu=$this->input->post('id_menu');

        $sens=$this->input->post('sens');

        $page=new page();

        $page->select_root($id_menu);

        $page->get_root();

        $page->get_by_id($id);

        $bro=new page();

        $bro->select_root($id_menu);

        $bro->get_root();

        $bro->get_by_id($id); 

        if($sens=='up')

        {

            $bro->get_previous_sibling();

            $bro->make_next_sibling_of($page);

        }

        elseif($sens=='down')

        {

            $bro->get_next_sibling();

            $page->make_next_sibling_of($bro);

        }

    }

for the up direction i move the previous sibling to next to the current its the same as moving current as previous ... and it workrs Smile

i want to change parent of a node but it doesnt work... and same if i try last_child_of

Code:
function move_item_parent()

    {

        $id=$this->input->post('id_item');

        $id_menu=$this->input->post('id_menu');

        $id_par=$this->input->post('id_parent');

        $page=new page();

        $page->select_root($id_menu);

        $page->get_root();

        $page->get_by_id($id);

        $parent=new page();

        $parent->select_root($id_menu);

        $parent->get_root();

        $parent->get_by_id($id_par); 

        $page->make_first_child_of($parent);        

    }

can somebody help me or direct me in a plugin which works in nested set?

datamapper is so easy to use i don't want to turn into doctrine Sad

thanks in advance
