Docker error related model longclawproduct.Product cannot be resolved

[tabias]

When cloning the git repo I followed the procedure:

Clone this repository

$ git clone https://github.com/JamesRamm/longclaw_demo.git
$ cd longlcaw_demo
Build the docker image

$ docker build -t longclaw-demo .

but got stuck building the docker. (log below)

As products is being migrated first I don't see where this error is coming from.

Somehow the issue is initiated using the longclaw build version from git.

doing the manual process as follows gives a working demo result:

1. clone this git
2. install the requirements.txt
3. overwrite longclaw with the pip version (0.2.0) instead of the git version
4. migrate

I'm still looking into the source of longclaw to find the specific problem.

Ok
Problem here is that my focus is on longclaw development and I'm not able to keep longclaw_demo in sync with latest changes.

Solution is simple - I should start tagging longclaw_demo with the longclaw version and tie the requirements to that.

This would mean that:

• A 0.2.0 tag on longclaw_demo should install longclaw 0.2.0 and work :)
• longclaw_demo master branch can continue development at its own pace (lagging behind longclaw a bit basically).
• A new longclaw release should ideally be followed straight away by a new longclaw_demo tag with a working longclaw_demo version for that release.
