Magic Link and Remember Logins - Does this work?

Anvil Q&A
1

I have magic link authentication turned on and my users are complaining they have to login every couple of hours, even though I have the remember login state set to 1-year.

When I look at the user tables, the remember_logins column is None for all rows.

Should this work?

:thinking:

What happens if you put a server call right after the login splash screen that calls the server module and does a anvil.users.get_user() to get the user row, then passes the user row to anvil.users.force_login(user_row)

Will it create the entry in the remembered_logins column of the users table?

Sorry for the delayed response.

Just did this ā€¦

@anvil.server.callable
def force_user():
  my_logger.debug("ENTERING: force_user")
  cur_user = anvil.users.get_user()
  my_logger.debug(f"CUR USER: {cur_user}")
  anvil.users.force_login(cur_user)
  my_logger.debug("forced a login")

And in the Users table, the last_login is now populated but the remembered_logins is still blank.

Now trying this variant:

@anvil.server.callable
def force_user():
  my_logger.debug("ENTERING: force_user")
  cur_user = anvil.users.get_user()
  my_logger.debug(f"CUR USER: {cur_user}")
  anvil.users.force_login(cur_user, remember=True)
  my_logger.debug("forced a login")

Will have to wait some time to see of the remembering is working, but at least the column in the users table has data.

Are you able to create a minimal example to replicate the issue and share a clone link?

Does this mean it works for you?

Iā€™m juggling a few different projects and am in the midst of being nomadic ā€¦ so my capacity is extremely constrained to do much beyond critical/urgent tasks.

No I do not use this feature.

Looking at the anvil-runtime source codeā€¦it appears that remembering who is logged in is not a feature of the magic link method.

Your latest workaround will probably work.

Iā€™m sorry for resurrecting this old thread, but I just encountered the same issue. @meredydd Has this been classed as a bug? For the user, the behaviour is clearly not what the interface suggests.

The workaround does indeed successfully remember the login, but because it does not capture the value of the ā€œRemember meā€ checkbox, itā€™s not fully functional. It always remembers the login, regardless of whether the user checked the box, so now the behaviour is wrong in the other direction.

Hi all!

Iā€™ve been able to recreate this. Iā€™ll raise the issue internally to figure out the intended behavior and get a fix shipped if necessary. Iā€™ll update this thread when I have more info!
