====Installation====
as root: 
<code>
  easy_install pip
  pip install virtualenv
</code>


As normal user:
<code bash>
$  virtualenv projectname
$  cd projectname
$  source bin/activate
(projectname):$ pip freeze
(projectname):$ pip install django==1.6.7
(projectname):$ pip install south django-registration stripe
(projectname):$ django-admin.py startproject djlogin
</code>

Just a bunch of code i will probably **not** remeber
<code bash>
  python manage.py startapp myapp
  python manage.py syncdb
  python manage.py runserver
</code>
First command creates app myapp, second creates tables in database according to models.py, and the third one starts the server at port 8000.

In case you want to access the server from outside:
<code>
  python manage.py runserver 0.0.0.0:8000
</code>

Best editor for django/python development
  * http://komodoide.com/download/edit-linux64/

====South====
  * great tool for migrating & altering DB

To start using south...

Make sure your django tables match your current database tables exactly - if you planned to add or remove columns, comment those out and run:
<code>
./manage.py schemamigration myapp --initial name_of_migration
./manage.py migrate myapp --fake
</code>
Make changes to your django model and then run:
<code>
./manage.py schemamigration myapp --auto
./manage.py migrate myapp
</code>

====Vim python autocomplete====
  * https://github.com/davidhalter/jedi-vim
  * in debian following packages needed to be installed: vim-athena vim-nox
  * also pathogen addon has to be installed: https://github.com/tpope/vim-pathogen

====Python source code encodings====
If UTF-8 source file encoding is needed ... 
<code>
# -*- coding: UTF-8 -*-
</code>
...put this on the beginning of the source file.


====Database settings====
MyISAM storage:
<code>
mysql>>> ALTER TABLE search_ftext ENGINE = MyISAM;
</code>

Create fulltext index

<code>
mysql>>>  ALTER TABLE search_ftext ADD FULLTEXT (text);
</code>

if Django keeps falling after editing in admin - convert table DjangoAdminLog to the same collation as other tables:
<code>
alter table auth_user_user_permissions convert to character set utf8 collate utf8_unicode_ci;
</code>
