Some Windows Pinax help

This is just an overview: See the Wiki here for the nitty gritty…

For widows users: 1st thing which is not obvious is that all the installation steps must be done from the command shell in windows (preferably in admin mode if on Vista), from the correct directory. You do not use the python idle environment, nor do you explicitly invoke python, (except at the very end!!)

You must have SVN and GIT installed and on your path (which the “normal” installations take care of) note that Tortoise SVN is not sufficient (It does not have the command line interface) Slik svn does http://www.sliksvn.com/en/download, both can co-exist, Tortoise Git  http://code.google.com/p/tortoisegit/ is a good install for windows users and includes a complete tool set. The boot and install scripts depend and use these programs to install source code from many locations/libraries, really very cool…therefore you must have a good internet connection!!

You should probably execute the command shell with the “run as administrator” if using Vista, if xp you should be an administrator.

You do not need to do a checkout or download of any files other than the “pinax-boot.py” file, which should be placed in a directory that you want to use as your base installation directory.

a general outline of what happens…..
You run pinax-boot.py
It downloads the base Pinax repos and installation scripts.
You “activate” pinax-env
(it is really running in the command shell)
That changes your prompt. You will then do your directory changes within this new pinax-env prompt……
(this took a while for me to wrap my head around but I now agree that it’s a really neat good idea!!, I would not try without it)
pip install <<<this step processes a very long and involved script which gets numerous dependent/pre-requisite packages and places them properly in the “virtual-environment”
you remain in pinax-env all during this process….and following….
pinax-admin clone_project retrieves the proper stuff from the set of files that you have downloaded and sets up another directory containing just your project as a django project…
It is a good idea to go with the default sqllite db (ie. don’t touch settings!!)
Now follow the directions, again from within pinax-env,, and cd into your project directory and runserver.. You should get a nice pinax complaint about no db.. follow the instructions to syncdb and so on…

Shooting myself in the head with Python, Django,Pinax

Well I decided to take some time off from working with the App-engine-patch and try Native Django,, go more mainstream so I could take advantage of more robust database and tutorials…

I’m using Python 2.62 Win 64 Eclipse 3.4 Ganymede, and trunk SVN Django 1.1

1st, one must install a Mysql driver The one in the “official library won’t work, version differences.. go here for a windows installer for Python 2.6 https://sourceforge.net/forum/forum.php?thread_id=2316047&forum_id=70460  Fwiw I’m using 32 bit versions although there is a 64 bit version available (for both Python and the Mysql driver (lower down on that thread).

You also need to add the following change manually to the Mysqldb code

About warnings:

1) file “__init__”, replace:

from sets import ImmutableSet
class DBAPISet(ImmutableSet):

with

class DBAPISet(frozenset)

2) file “converters.py”, remove:

from sets import BaseSet, Set

3) file “converters.py”, change “Set” by “set” (IMPORTANT: only two places):

line 48: return set([ i for i in s.split(‘,’) if i ])
line 128: set: Set2Str,

I hope this be useful.

I realized That I had not been documenting myself when I blew up and was about ready to re install and realized I’d have to look every thing up again… Hence back to posting!

One of the most interesting revelations for me recently is how Python “installs” and referrers to packages and extensions. At this point I now think that all the trashing about is a bit too much on many installs. Looking in site-pkges in Libs in the Python directory I noticed several .pth files named for some of the extensions I was installing and using, the file was the module name.pth.. and contained the full path to the module… cool! So that is a mechanism that can be used to create a nice place to keep that stuff without messing up your basic Python install… good to know..

Another major revelation has been the use of revision control systems,,, It seems that it is well worthwhile to have a copy of all of the major systems on your machine. Git, SVN and Mercurial. If you checkout a copy of a system like Django,,, then when you want a update to the current version just do another checkout and your done!

Btw it turns out that even if you use TortoiseSVN as I do it is a good ides to install Silk SVN also because Tortoise does not provide command line access, which is used by some packages for automated installation/updating, in particular Pinax! So even if you don’t want command line you need to have it on your system…

If you use tagging with the 1.0 or latter Django you must use the svn version of tagging ….
