Goto django 1.9
When trying the dj1.9 version with docker, I got :
ImportError: No module named importlib
@thomasfillon : Yes, of course... !
Zeus:Telemeta anas$ git checkout dj1.9

Already on 'dj1.9'
Your branch is up-to-date with 'origin/feature/dj1.9'.

Ok thank you Anas.
The error you get here may be related to dependencies that also need to be updated. The upgrade to Django 1.9 from 1.6 has induced some changes in requirements and database migrations.
Here is the updgrade process from Telemeta with django 1.6. This upgrade process is not fully validated yet and may cause damage in your current database. Please do not try this on your production database.
Upgrade process:
- Update git submodules (Timeside)
-
git submodule update --init --remote --recursiveEDIT : this line is wrong !--remoteoption should be remove. See coments at the bottom of this page
-
- Update Parisson base docker image and build:
-
docker pull parisson/timeside:latest-dev -
docker-compose -f docker-compose.yml -f env/dev.yml build
-
- you also need to clear the existing Timeside Database (models have changed but it's safe for Telemeta models and database)
-
docker-compose -f docker-compose.yml -f env/dev.yml run app python manage.py migrate server zero-docker-compose -f docker-compose.yml -f env/dev.yml run app python manage.py migrate server - When upgrading from Django 1.6, you also need to apply migrations for South to Django managed migrations:
-
docker-compose -f docker-compose.yml -f env/dev.yml run app python manage.py migrate --fake-initial
-
- At least, launch the Telemeta server:
-
docker-compose -f docker-compose.yml -f env/dev.yml up
-
Any feedback on this upgrading process would really be appreciate. Thanks !
Regarding the current status of the feature/django1.9 branch, there are some issues regarding the url namespace. Actually, all telemeta views need to be declare with the telemeta namespace in urls.py otherwise django can not match the view and the url patterns.
I suspect that some old fashioned views and some ad-hoc code function need to be rewritten to match modern Django framework but this still need to be checked with @yomguy

It seems that there is some problems regarding the git submodules and especially about the version of the Timeside-Diadems one.
I will try this on a fresh install to fully understand what happens.
@AnasGhrab Did you start from a brand new directory ?
OK I think I get it.
There is a mess with Timeside / Timeside-diadems version between sub-modules and docker image. I'll do the clean up right now..
the fault seems to be on the Update git submodules command in the instructions above:
git submodule update --init --remote --recursive does not seem to be the proper way to do this.
@AnasGhrab @lluc In the 'Upgrade process' above, please consider the following
- Update git submodules (Timeside)
-
`git submodule update --init --recursive`
-
the --remote option was apparently updating the different submodule to the master branch head version.
Please, before properly updating your submodules, please clean up your submodule directories with:
git submodule deinit -f .
and then:
git submodule update --init --recursive
@thomasfillon Yes.. I think I had to try again.. i've missed something ;)
ok thanks
--fake-initial should be ok since the django version is updated to 1.8 or 1.9 in the feature/dj1.8, feature/dj1.9 branches respectively.
Here's what I did locally on my OS X for testing. After deleting containers, from the master branch of Telemeta :
- Change the docker-compose.yml to add the utf8 command;
-
docker-compose up; - Merge the remotes/origin/feature/dj1.9
- Start following the commands above..
But, I get :

It seems to be ok after another docker-compose up. Sorry for all these messy comments.. I'd like to find exactly the good procedure.
Now it seems to be much, but it is labyrinthic ;) I had first to merge the dj1.8 before the dj1.9, then also the dev branch. Now I get this :

The good procedure should be the one in my comment of the 22 february (except the git submodule command line). If this procedure is not good, we should correct it.
Sorry but I don't understand why you need to do all this merge ? why the dev branch ?
Currently only the feature/dj1.8 is working, the feature/dj1.9 has some problems related to views. Would you mind testing only the feature/dj1.8 branch only for now ?
@thomasfillon I got a well working dj1.8. With the dj1.9, I get this error :
