Odoo 12中没有名为Slugify的模块

import re

def slugify(text):
    # 将字符串转换为小写，并将非字母数字字符替换为连字符
    slug = re.sub(r'[^a-zA-Z0-9]+', '-', text.lower())
    # 去除开头和结尾的连字符
    slug = slug.strip('-')
    return slug

from odoo import models, fields

class Product(models.Model):
    _name = 'product.product'

    name = fields.Char('Name')
    slug = fields.Char('Slug', compute='_compute_slug')

    def _compute_slug(self):
        for product in self:
            product.slug = custom_slugify.utils.slugify(product.name)
