via Chris Moyer: OSX, Vim, and Python.

I do it this way:

pip -E PATH_TO_VIRTUALENV install http://dist.repoze.org/PIL-1.1.6.tar.gz

This installs a slightly repackaged version of PIL. The latest PIL version is 1.1.7, but as far as I know it’s not available in this form.

The photo gallery example assumes an apache2 + mod_python setup. I didn’t really find it straightforward to get this running from the description in the appendix, so here is how I got it to work (after installation of apache2 and mod_python, of course):

In /etc/apache2/sites-available/default, change lines:

        <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                allow from all
        </Directory>

To:

        <Directory /var/www/>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride AuthConfig
                Order allow,deny
                allow from all

                AddHandler mod_python .py
                PythonHandler mod_python.publisher
                PythonDebug On
        </Directory>

Then I did the changes in /etc/apache2/httpd.conf, but slightly different from the book by adding a PythonOption django.root (didn’t work for me with the setup in the book):

<Location "/gallery/">
      SetHandler python-program
      PythonHandler django.core.handlers.modpython
      SetEnv DJANGO_SETTINGS_MODULE gallery.settings
      PythonOption django.root /gallery
      PythonDebug On
      PythonPath "['/path/to/django/root', '/home/user/django-stuff'] + sys.path"
</Location>

With an additional entry for media files:

<Location "/gallery/media">
      SetHandler none
</Location>

Now, I created a directory /var/www/gallery and a /var/www/gallery/media like explained in “Preparing for File Uploads” and edited settings.py:

MEDIA_ROOT = '/var/www/gallery/media/'
MEDIA_URL = 'http://localhost/gallery/media/'
ADMIN_MEDIA_PREFIX = 'http://localhost/gallery/media/admin/'

Where admin is a symbolic link (/var/www/gallery/media/admin) to the admin media directory in the Django installation. The two last entries where not mentioned in the book, but they made it work…

With the settings described above and the PythonOption django.root in httpd.conf, I didn’t need the section about DRY URLs. And it worked – as opposed to the stuff in the book.

With all the configuration stuff in place I typed the code outlined in the chapter and to begin with I couldn’t see any photos, except for the thumb_url in items_list.html (typo: items_listing.html in the last paragraph page 175). I managed to get it working by changing some lines in items_detail.html and photos_detail.html though:

22                 <img src="{{ photo.image.thumb_url }}" />

instead of

22                 <img src="{{ photo.get_image_thumb_url }}" />

and

8 <img src="{{ object.image.url }}" />

instead of:

8 <img src="{{ object.get_image_url }}" />

The alternatives that worked seems more intuitive to me.

I also imported list_detail from django.views.generic in urls.py, but am not sure if this was needed. The photo gallery seems to work fine except for the thumbnails in index.html. I’ve noticed that the code in urls.py for that template is different from the others, using simple.direct_to_template, but I haven’t managed getting that part to work.

Thanks to this thread for getting mod_python up and running: Python and Apache2

Please configure a Python or Jython interpreter in Window -> Preferences -> PyDev
before creating a new Pydev project

• Press Apple key and , (Preferences) and browse to the Python Interpreters submenu
• Choose New in the upper right and browse to /usr/bin/python
• Eclipse will then take care of the rest for you – ie. updating the $PYTHONPATH

NOTE: I use Eclipse 3.3.2 on Mac OS 10.5.2.
