Odoo开启重置密码功能后提示'NoneType' object has no attribute 'get' ，调试代码发现

程序代码：
def action_reset_password(self, cr, uid, ids, context=None):
        """ create signup token for each user, and send their signup url by email """
        # prepare reset password signup
        create_mode = bool(context.get('create_user'))
        res_partner = self.pool.get('res.partner')
        partner_ids = [user.partner_id.id for user in self.browse(cr, uid, ids, context)]

        # no time limit for initial invitation, only for reset password
        expiration = False if create_mode else now(days=+1)

        res_partner.signup_prepare(cr, uid, partner_ids, signup_type="reset", expiration=expiration, context=context)

        if not context:
            context = {}
context为空造成的，把这个代码放前面就可以了。
 
程序代码: 
if not context:
            context = {}
