Hello,

I try to understand how the fuel-nestedsets package is working and what I need to do in fuel to use it.

What I have understood so far is the following. I will use this with Multiple Trees. So I made one Model "Metatree" which contains the IDs and Names of the different trees:
http://snipr.it/~CC

Then I have the Model "Tree" which contains the single nodes. For using Multiple trees I set 'tree_field' => 'tree_id', as this field will contain the IDs from the Model "Metatree":
http://snipr.it/~CD

Up to now, I have no field for the name of the node. Will extend this later. But this will also be in the tree table.

What I understood so far is the following:
To create a new tree I need to
1) Create a new Object of type "Tree"
2) Select the ID from the Model "Metatree"
3) Pass this ID to function "tree_select"
4) Create the new tree object with function "tree_new_root"
Here is my complete Code:
http://snipr.it/~CE

I assumed that the selected ID from Model "Metatree" is stored as "tree_id" in the Model "Tree", which actually doesn't work, as "tree_id" is always set to the next free number like an AutoIncrement field.

If I check the two functions in the package I see that while selecting "tree_value" is used and while building new rootm, then "tree_field" is checked for duplicates. Is that the reason this is not working???

Don't know if I understnd the way I need to do something correctly.
Perhaps somehone can help me in that matter.

Thanks Kay

tree_new_root() generates a new tree root with a unique tree id, so it you use a second table to create your tree id's, you should not use that method, but create the root node manually:

$tree = Model_Tree::forge(array(
    'left_id' => 1,
    'right_id' => 2,
    'tree_id' => $your_meta_tree_id;
));
$tree->save();

ok, understood

Let's say for a moment I don't want to use two models, only one Model "Tree".

If I then want to add a new tree, I only need to set the name for it and call $tree->tree_new_root(); ???
Tried this, but "name" (Value of the tree) is always empty. Here is my code:

    public function action_createtree()
    {

        if (\Input::method() == 'POST')
        {
        \Debug::dump(\Input::post()); #die;
        $tree = \Metadata\Model_Tree::forge();   
        $tree->tree_new_root(); 
        \Debug::dump($tree); die;
        } 

        return \Theme::instance()
        ->get_template()
        ->set(  'content', 
                \Theme::instance()->view('admin/meta/createtree')
            );
    }

Thanks Kay

tree_new_root() only sets left, right and tree id's. It doesn't touch anything else in the object.

kay899

ok and how can I then add new values, like "name"?

Harro

$tree->name = 'Value';

like for any other (ORM) object ?
