Hello 

I developed a custom module for currency rates. I have added extra fields like "special_currency_rate" to the res.currency model during the development phase of this module. However, when I upload the changes I make to Odoo.sh , I am getting error in odoo.log file like this: psycopg2.ProgrammingError: column res_currency.special_currency_rate does not exist.

I've tried some ways to solve the problem:

- I changed name of variable

- I removed everything about "special_currency_rate" from methods and views and only I defined the variable.

But none of it worked. How can I solve this problem urgently?

My class definition is as follows:

class ResCurrency(models.Model):

    _inherit  = 'res.currency'
    rate = fields.Float(compute='_compute_current_rate', string='Efektif Satış', digits=(12, 6),

                        help='The rate of the currency to the currency of rate 1.')

    banknot_buying_rate = fields.Float(digits=(12, 6), string="Efektif Alış", compute='compute_banknot_buying_rate')

    forex_selling_rate = fields.Float(digits=(12, 6), string="Döviz Satış", compute='compute_forex_selling_rate')

    forex_buying_rate = fields.Float(digits=(12, 6), string="Döviz Alış", compute='compute_forex_buying_rate')

    special_currency_rate = fields.Float(digits=(12, 6), string="Özel Kur")
