User virtualenv and pip to avoid dependency problems.

$ yum install python2.6 python-setuptools python-imaging
virtualenv --no-site-packages mysite-env

“No site packages” create isolated env from host env.

Install Django. From version 1.7.0 django has built-in migration, south is not needed.

  source mysite-env/bin/activate
  (env)$ pip install django django-cms <del>south</del>
  (env)$ django-admin.py startproject mycmsproject
  

Install JPEG support on host (outside virtualenv!):

  sudo yum install python-devel libjpeg-devel freetype-devel libpng-devel
  sudo yum install mysql-devel mysql-common mysql-libs    

Reinstall Pillow

  pip install -I Pillow    

Mysql-python

  pip install mysql-python

Following django packages are listed in requirements.txt:

# Bare minimum
django-cms>=3.0

# These dependencies are brought in by django CMS, but if you want to
# lock-in their version, specify them
Django>=1.7

South==1.0.2 # Only needed for Django < 1.7
django-mptt==0.6.1
django-sekizai==0.7
django-classy-tags==0.5
djangocms-admin-style==0.2.2
six==1.3.0

# Optional, recommended packages
Pillow>=2
django-filer==0.9.8
cmsplugin-filer==0.10.1
django-reversion==1.8

# Server packages
mysql
django-debug-toolbar

Install those packages:

pip install -r requirements.txt

Install third-party app in current project:

(vfoss_env)[td@localhost vfoss_org]$ pip install --install-option="--install-purelib=$(pwd)" easy_thumbnails

Dump libs:

  $ pip freeze>requirements.txt
  $ pip install -r requirements.txt 
  

django-admin.py startproject myproject

Open the settings.py file in your project.

To make your life easier, add the following at the top of the file:

# -*- coding: utf-8 -*-
import os
gettext = lambda s: s
BASE_DIR = os.path.dirname(os.path.dirname(__file__))

Add the following apps to your INSTALLED_APPS. This includes django CMS itself as well as its dependencies and other highly recommended applications/libraries:

'cms',  # django CMS itself
'treebeard',  # utilities for implementing a tree
'menus',  # helper for model independent hierarchical website navigation
'south',  # Only needed for Django < 1.7
'sekizai',  # for javascript and css management
'djangocms_admin_style',  # for the admin skin. You **must** add 'djangocms_admin_style' in the list **before** 'django.contrib.admin'.
'django.contrib.messages',  # to enable messages framework (see :ref:`Enable messages <enable-messages>`)

   pip install git+https://github.com/nadobit/django-filer.git@support/0.9.8

Bug: https://github.com/django-debug-toolbar/django-debug-toolbar/issues/457

Setup Debug-toolbar explicitly as followed:

During transition from South to Django 1.7, we have to specify which app use which migration solution using

146 
147     ## not checked. vim 0001* in app/migrations to see if it use django migration or South.
148     # Add also the following modules if you're using these plugins:
149     #'djangocms_file': 'djangocms_file.migrations_django',

158     #'aldryn_news': 'aldryn_news.migrations_django',
159     }

From django 1.7 no syncdb but using South:

  ./manage.py makemigrations
  ./manage.py migrate
  python manage.py migrate app_name
  ./manage.py cms check    
  #admin
  python manage.py createsuperuser

  python manage.py validate
  
  python manage.py runserver

Django migration tracks app migration using database:

+-----------------------+
| Tables_in_vfossdb     |
+-----------------------+
| django_migrations     |
| django_select2_keymap |
+-----------------------+

“makemigrations” will create migration files and “migrate” actually execute those files. In case database table of an app already exists, using “–fake” will skip creating the table.

restart django-cms after adding apphook to a page

django.db.migrations.state.InvalidBasesError: Cannot resolve bases for [<ModelState: 'cmspluginvfossproject.ProjectPlugin'>] This can happen if you are inheriting models from an app with migrations (e.g. contrib.auth) in an app with no migrations; see https://docs.djangoproject.com/en/1.7/topics/migrations/#dependencies for more

  ./manage.py migrate --fake cms zero
  

or try remove old migrations files and recreate them:

  rm cmsplugin_vfoss_project/migrations/0001*
  ./manage.py makemigrations
  ./manage.py migrate

./manage.py makemigrations
./manage.py migrate

Only the sqlmigrate and sqlflush commands can be used when an app has migrations.

  ./manage.py sqlflush --help
  Returns a list of the SQL statements required to return all tables in the database to the state they were in just after they were installed.

In MySQL Database delete row 'djangosessions' from the table 'djangomigrations'.

  delete from django_migrations where id=17;

Delete all migration files in migrations folder.

Try again python manage.py makemigrations and python manage.py migrate command.

  There is no South database module 'south.db.mysql' for your database. Please either choose a supported database, check for SOUTH_DATABASE_ADAPTER[S] settings, or remove South from INSTALLED_APPS.
  
  pip uninstall South
  

Django-cms 3.1. migrations by Django is now in migrations and south migration is in southmigrations. so remove the paths in settings.MIGRATIONMODULES.

In Django framework there is a chain of services / component processing request and return response. E.g., Request –

> View --> Form --> DB, Response or Request --> ModelAdmin --> Form --> DB, Response. Each component has functions that can be overridden to modify the data object passed through the chain.
