LAVA Dashboard (deprecated)

"500 Internal Server Error" for lava dashboard in development mode

Asked by Terry Guo

Hi,

I want to customize the lava dashboard, so I set up the development environment by following file SETUP-WEBDEV-ENV in package lava-deployment-tool. It works. But when click the menu Dashboard --> Bundle Streams, I always get "500 Internal Server Error", same issue happens to menu Dashboard --> Tests and etc.

The log file /srv/lava/instances/dev/var/log/lava-uwsgi.log says:

WARNING:root:dataview-specific database connection not available, dataview query is NOT sandboxed
ERROR:django.request:Internal Server Error: /dashboard/streams/

It seems after I checkout lava dashboard code into folder /srv/lava/instances/dev/src, there isn't an explicit step in file SETUP-WEBDEV-ENV to initialize database for lava dashboard. So beside running "./setup.py develop", what else should I do?

Figured out by myself.

According to file SETUP-WEBDEV-ENV, you need to perform following steps:

1) Checkout the lava dashboard source code into folder /srv/lava/instances/dev/src.
2) Run command "./lava-deployment-tool install_config_app dev"
3) Activate virtualenv: ". /srv/lava/instances/dev/bin/activate"
4) Go to folder /srv/lava/instances/dev/src/lava-dashboard and run command "./setup.py develop".

For lava dashboard, you need to run another command to set up the DB.
5) ./lava-deployment-tool manage dev migrate

Then no "500 internal error".

I have not read those instructions in a while. You need to run lava-server manage syncdb and lava-server manage migrate. You should have started with lava-deployment-tool setup, followed by install with the latest 2012.03 pybundle from lava-project download page on launchpad
