Hello, 

I want raise a warning via a wizard in the create function and continue with the transaction when the proceed button is clicked.
What am I missing?

Here is my code which checks whether the overdraft account limit has been exceeded, raises a message/warning and allows a transaction to continue.

@api.model
def create(self, vals):
    credit = 0
    debit = 0
    if "line_ids" in vals.keys():
        for line in vals['line_ids']:
            if line[2]['credit']:
                account = self.env['account.account'].browse(line[2]['account_id'])
                account_lines = self.env['account.move.line'].search([('account_id', '=', account.id)])
                for lines in account_lines:
                    credit += lines.credit
                    debit += lines.debit
                new_account_credit_limit = (credit + line[2]['credit'] - debit)
                if account.account_credit_limit:
                    if new_account_credit_limit > account.account_credit_limit:
                        try:
                            wizrd_action_id = self.env.ref('overdraft_limit.view_warning_wizard_form')
                            msg = 'Making this transaction will exceed the Overdraft limit defined for " %s " account.' % account.name
                            raise RedirectWarning(msg, wizrd_action_id.id, _('Are sure you want to proceed?'), {'active_id': self.id, })
                        finally:
                            account.account_credit_limit = new_account_credit_limit
                            self.state = 'posted'

    result = super(AccountMove, self).create(vals)
    return result
