Datahub module not found

[willjharmer]

When building and running with vagrant, I consistently get a successful vagrant up (and provision) but when accessing the site I then get a django error page, telling me 'No module named datahub'. I then go into the app container and have to rerun the thrift generators for datahub.thrift. Then everything works.

Error page and environment is attached. No module named datahub.pdf

This is an ongoing problem. Unfortunately, it's very hard for us to debug, since it happens during vagrant setup, and doesn't seem to happen consistently.

@willjharmer - I know you've already fixed this, but in case anyone else encounters it, here are some commands that should fix the problem:

# log into vagrant and become the superuser
$ vagrant ssh
$ sudo su

# go into the app container
$ docker exec -ti app /bin/bash

# run the setup script that was supposed to run at start
$ source src/setup.sh

# exit the app container
$ exit

# restart containers
$ dh-stop-containers
$ dh-start-containers

If this doesn't work for you, please ping us on this thread and @justinanderson or I will give you a hand. This is a known and annoying issue, that's been particularly difficult to track down.

This should be fixed by https://github.com/datahuborg/datahub/commit/f552f2ba75e733aee856f53f10edb47b530a6076, which was just merged into master and tagged as v0.4 yesterday. You can upgrade with:

git checkout master
git pull
sudo su
# Rebuild the Docker images
dh-build-images
# Stop the containers
dh-stop-containers
# Delete the app and web containers
docker rm app web
# Recreate the app and web containers
# (ignoring complaints that the other containers already exist)
dh-create-dev-containers
# Restart DataHub
dh-start-containers
# Once migrations finish and the script returns control,
# DataHub should be up and running again.
