python - Django deafult_token_generator creates token tha is almost immediately expired -

for set/reset password in django app use built-in django resetpasswordrequestview , resetpasswordconfirmview. them working fine. i've created function that's sending email user when administrator creates account (there no registration "common users" on site). here's code:

first 2 views works great, function (using same token generator) creates urls token, not valid. almost, because if check them inside function (right after creating , sending mail) valid, then, when try set password via url given in mail, , got 'the reset password link no longer valid.' in settings have password_reset_timeout_days = 1 shouldn't problem. ideas?
