model is 'product.category ', want to inhereit and add a field 'level' to add the levels to find which level record i want.

we knew that by default (as recommended) that first entry 'All' here should present to start the parent child relations.

when user create a new category and select All as its parent, we knew that its level is 1 and we can add 2, programatically it should be parent level + 1 ... so we can add levels of any depth.

i don't know how to code it, so please help me for the below onchange function (or any other better approach, please specify), modify it to achieve what i wants to have.

@api.onchange(parent_id):

def _onchange_parent_id(self):

  find the level of parent here...

  self.level = parent_level + 1

regards

Hello SmithJohn45,

Suppose we have a product category hierarchy as below


A > B > C > D


and we need to find the level for the category "C" with the code (the answer is 3)

So to find the level for the category, here is the method that you need to write:


def find_level_of_category(self, catg_id):

    level = 1

    if catg_id.parent_id:

        parent_id = catg_id.parent_id

        while (parent_id):

            level += 1

            parent_id = parent_id.parent_id

        return level

    return level



You can simply call this method to your onchange, you need to pass "self.parent_id" as a parameter into the above method, so it will give you the level of the "self.parent_id".


Thanks!

@Neha Sharma, please check, if it is ok or i made mistake(s)

from odoo import api, fields, models

class ProductCateg(models.Model):

_inherit = 'product.category'

level = fields.Integer(string='Level')

@api.onchange('parent_id')

def find_level_of_category(self):

levels = 1

if self.parent_id:

parent_id = self.parent_id

while (parent_id):

levels += 1

parent_id = parent_id.parent_id

self.level = levels

@Neha Sharma, implemented the code for model, updated manually level column for All to 1 and All / Electronics to 2, from UI created a record, choose All / Electronics as its parent, but level not updated with required value. ( i have copy/pasted your last code as it is, indent with pycharm option and restart server, upgraded module and then checked ) anything else i missed ?

Neha Sharma

Can you share a screenshot of your pycharm code?
