I'm trying to create a field “complete_name” that displays a hierarchy name similar to whats done on the product categories grid but I can't seem to get it to work. It just puts Odoo in an endless loading screen when I access the relevant view using the new field "complete_name".

I have tried to copy the code used in \addons/product/product.py and migrate to work with Odoo 9 API by using compute instead of .function type but it did not work.

Can someone help me understand whats wrong? Below is my model class which works fine without the complete_name field in my view.

class cb_public_catalog_category( models.Model ):
    _name = "cb.public.catalog.category"         
    _parent_store = True             
    parent_left = newFields.Integer( index = True )      
    parent_right = newFields.Integer( index = True )        
    name = newFields.Char( string = 'Category Name' )         
    child_id = newFields.One2many( 'catalog.category', 'parent_id', string = 'Child Categories' )         complete_name = newFields.Char( compute = '_name_get_fnc', string = 'Name' )
    
def _name_get_fnc( self ):
    res = self.name_get( self )         
    return dict( res )
