Thanks for pointing me in the right direction, Stifan.
I added this line to the model file:
db.auth_user._after_update.append(lambda s: remove_mobile_token(s, db))
and this function in a module
def remove_mobile_token(set, db):
request = current.request
#delete mobile tokens if the change IS NOT from reset_password
if request.function == "user" and request.args>0 and request.args(0)==
"reset_password" :
user_id = set.select().first().id
db(db.mobile_tokens.username==user_id).delete()
db.commit()
I tried using the f variable from the after_update callback (containing
dictionary of fields to be updated) to check for existence of "password" in
f, but changes to the auth_user table using auth.profile() form contains
all the fields for auth_user, thus any changes using the auth.profile()
form would trigger a mobile_token deletion.
To make sure only changes to the password field would trigger mobile_token
deletion, I check that the request is coming from the user/reset_password.
