This is really weird. I am beginning to think that after I clone my virtual machine, where the py4web app sits, I lose the ability to access the dashboard. As if my password gets screwed. It does not accept it.

Anyone has experienced the same? I try to reset the password but still does not work.

Any other way to create users?


Thanks

How exactly did you intend to reset the password?
Do you have the password.txt file?

If the password.txt file does not exist or py4web does not find it, you should see a message when starting py4web “You have not set a dashboard password.”

You have not set a dashboard password. Run "/home/carlos/p1/py4web/py4web.py set_password" to do so.

Yes I set up a password. I used py4web set_password. I can see the password.txt. It used to work but not anymore

When I have had problems with the password it has always been because py4web could not find password.txt

py4web displayed the message "You have not set a dashboard password."

py4web looks for the password.txt file in the current working directory.

do you have any message from py4web about the password?
Won't you have more than one password.txt file in different directories?

What command are you using to start py4web?

What directory do you run it from?

For example, my directory structure looks like this:

/home/jim/dev/py4web/

apps directory is

/home/jim/dev/py4web/apps

I cd to /home/jim/dev/py4web and run

python3 py4web.py set_password

password.txt is then created in /home/jim/dev/py4web

I can then run (from the same directory)

python3 py4web.py run apps

I can then login to the dashboard

Is that the same structure that you're using?

A little background. I am on Ubuntu server py4web under nginx. Directory structure is:
  • I have it under /home/www-data/py4web/apps
  • And I have py4web running as a Service using systemd
  • I can open the dashboard but not log into.
At some point I could log into the dashboard. The only different significant change is that I started cloning the virtual guest where py4web resides.

What does your py4web service file look like?

[Unit]
Description=py4webstarter

[Service]
Type=simple
ExecStart=/bin/bash /home/www-data/py4web/py4start.sh



[Install]
WantedBy=multi-user.target



then py4start.sh:

#!/bin/bash
py4web run /home/www-data/py4web/apps

I wonder if the problem is that it can't find the password file.

There are a few ways I'd go about debugging this.

1. add a WorkingDirectory directive to the py4web .service file.

2. in py4start.sh add a cd /home/www-data/py4web

3. add the -p switch to the py4web run /home/www-data/py4web/apps command to explicitly tell py4web where to find the password file.
if the password file is in /home/www-data/py4web, then use this:

py4web run -p /home/www-data/py4web /home/www-data/py4web/apps

Can you try some of those and see what happens?

That was it. 

worked by adding the whole path to password.txt followed by the apps directory

py4web run -p /home/www-data/py4web/password.txt /home/www-data/py4web/apps



thanks Jim!!

Great news, glad you figured it out.
