Hi,

Try this code:

from odoo import models, fields, api

class ResUsers(models.Model):

    _inherit = 'res.users'

    token = fields.Char("Device Token", default="[]", groups="base.group_user")

    checkin = fields.Boolean(string='Check-in', default=False, groups="base.group_user")

    @api.model

    def create(self, vals):

        user = super(ResUsers, self).sudo().create(vals)

        _logger.info("user %s", user)

        # user.action_create_employee()

        return user

It seems like you were trying to modify the SELF_WRITEABLE_FIELDS and SELF_READABLE_FIELDS attributes of the model, but this is usually not done in the __init__ method. If you need to modify these attributes, it's better to do it directly in the class definition.

Hope it helps

The error message “RecursionError: maximum recursion depth exceeded while calling a Python object” is a safety mechanism in Python. It prevents your program from entering an infinite loop and using up all the stack space. This error usually occurs when the base case of a recursive function is not defined correctly.

In your case, the error might be due to the way you’re calling the super function in your __init__ method. When you call super(ResUsers, self).__init__(pool, cr), it calls the __init__ method of the parent class, which is res.users. If res.users is also inheriting from ResUsers, it will call the __init__ method of ResUsers again, leading to an infinite loop.

Here’s how you can fix this: 

class ResUsers(models.Model):

    _inherit = 'res.users'

    def __init__(self, pool, cr):

        super(models.Model, self).__init__(pool, cr)  # Call the __init__ method of models.Model instead of res.users

        type(self).SELF_WRITEABLE_FIELDS = list(self.SELF_WRITEABLE_FIELDS)

        type(self).SELF_WRITEABLE_FIELDS.extend(['token', 'checkin'])

        type(self).SELF_READABLE_FIELDS = list(self.SELF_READABLE_FIELDS)

        type(self).SELF_READABLE_FIELDS.extend(['token', 'checkin'])

    token = fields.Char("Device Token", default="[]", groups="base.group_user")

    checkin = fields.Boolean(string='Check-in', default=False, groups="base.group_user")

    @api.model

    def create(self, vals):

        user = super(ResUsers, self).sudo().create(vals)

        _logger.info("user %s", user)

        return user

This code calls the __init__ method of models.Model instead of res.users, which should prevent the infinite loop.
