Maximum function nesting level error

[legendarydrew]

Hello sir,
With the following code (regardless of what is inside the get()), I get a "Maximum function nesting level of '100' reached, aborting!" error:

$groups = ItemGroup::defaultOrder()->get(['name'])->toTree();
return $groups;

but this code works:

$groups = ItemGroup::defaultOrder()->get()->toTree();
return $groups;

The error appears to be a result of converting the tree to an array.

I've recenty updated Laravel to 4.2, and this issue also occurs with version 1.1. Perhaps I should stick with 4.1 for now?

This because of you receiving only a single column, to build a tree you're going to need _lft and parent_id columns.

$groups = ItemGroup::defaultOrder()->get([ 'name', '_lft', 'parent_id' ])->toTree();

hmm I have same problem

$cats = Category::defaultOrder()->get(['title', '_lft', 'parent_id'])->toTree();

I get error "Maximum function nesting level of '500' reached, aborting!"
I tired both examples from above non of them works

it only works if I add withoutRoot()

$cats = Category::withoutRoot()->defaultOrder()->get(['title', '_lft', 'parent_id'])->toTree();

but then I just see root level categories and no children categories nested inside children:[ ]

{"title":"books","_lft":"2","parent_id":"1","children":[ ]}

I need to get whole tree nest so i can reorder, search and edit categories with angularjs

Put parent to hidden property.

[atheleron]

you mean inside app/models/Category.php ??
I placed it

public $hidden = array('parent_id');

it just hide's parent_id from json output

{"title":"books","_lft":"2","children":[]}

[lazychaser]

No, not parent_id, but parent -- this is the relation, serialization of which is going down to infinite loop.

[atheleron]

It wooorks :) :) :)

i hide parent instead parent_id and I get full nested json tree withDepth()

$cats = Category::withoutRoot()->withDepth()->get()->toTree();

Thank youu

That what I had as a problem recently too.
To prevent duplicate issues, better to add a notice to the docs @lazychaser?

[Silentscripter]

The fix you provided makes impossibile to call parent relationship in toArray() or toJson() methods.... is there any official workaround for this?
Or at least it should be clearly stated in the docs...Spent a hour debugging this, it's a major problem imho
