Childrens it's just a related_items parameter for a field.
This code from models.py
> class Categories(models.Model):
> name = models.CharField(max_length=50)
> path = models.SlugField(max_length=50)
> parent = models.ForeignKey('self', null=True, blank=True, *
> related_name='childrens'*)
> order = models.IntegerField(default=1)
> isShow = models.BooleanField(default=True)
>
By using category.childrens.all() i just check are child items exists...
(any object have this category like 'parent')
Only for performance "if len(category.childrens.all()):" -> "if
> category.childrens.exist():"

Type is a "class Category". So it's realy object... Now i understand so i
wrong with identify my problem.
I want to build HTML through the custom tag, and i cant get access for
fields parametrs in custom tag script. In begin i suppose the problem
appear when i put objects in list. But type(list[0]) show thet in list i
have still object. I check in my template by {{item.field}} - it is show me
right data, so in template i sill can get access for fields of an object.
But when in my template i call my template tag, in template_tag code i
can't get access for fields... code is below.
In my template i do
> {% load menu_builder %}
> {{ list|BuildMenu }}
>
In menu_builder.py i have this code:
> def BuildMenu(list):
> html = ''
> for item in list:
> print item.path
> return html
>
it's isnt realy function - just check... but i get a exception
'list' object has no attribute 'path'
Exception Location: ..\templatetags\menu_builder.py in BuildMenu, line 7
Can you help with it? Where i make a wrong?
