MIgrating from Django 1.6 to Django 1.8

Transcript

1. Migrating from Django 1.6 to 1.8 Earthmiles
2. Why Django 1.8 over 1.6? • Prefetch object for advanced control on prefetch_related [earlier it had to be only .all()] • Conditional Expressions - Case() and When()
3. Django 1.8 - First Steps • Have good tests, with good coverage • $ pip install -U Django
4. Run tests and upgrade packages django-filter==0.11.0 python-social-auth==0.2.12 requests==2.7.0 requests-oauthlib==0.5.0 six==1.9.0 psycopg2==2.6.1 django-debug-toolbar==1.3.2 django-categories==1.3b8 nose==1.3.7 django-nose==1.4.1 factory-boy==2.5.2 django-taggit==0.17.0
5. New admin has quirks (for good) class TrackedActivityForm(forms.ModelForm): class Meta: model = TrackedActivity + fields = “__all__” #now required for all fields case
6. Schemamigrations from 1.6 (with South) to 1.8 • Perhaps a better way of achieving this is to migrate to 1.7 first and then to 1.8 • At Earthmiles, we migrated directly to 1.8
7. Schemamigration Steps • All steps up to this point • Remove 'south' from INSTALLED_APPS. • Remove South from requirements.txt • Delete all your (numbered) migration files, but not the directory or __init__.py - make sure you remove the .pyc files too. • find . -name '*.pyc' -print -exec rm -rf {} \; • find . -name '00*.py' -print -exec rm -rf {} \;
