This snippet uses signals to replace the `contrib.auth.models.User.set_password()` function with one that uses *crypt* instead of *sha1* to hash the password.
*Crypt* is of course cryptographically inferior to *sha1*, but this may be useful for interoperability with legacy systems e.g. when sharing a user authentication database with unix, a MTA etc.
For some reason the `User` class doesn't emit a `class_prepared` signal, which would otherwise be a better choice here. That's why I had to resort to patching each `User` instance separately.
A clean way to deploy this snippet is to place it in the `models.py` of an otherwise empty app, and add the app in `settings.INSTALLED_APPS`. The order of `INSTALLED_APPS` doesn't matter since we're patching instances, not classes.
A CompressedTextField to transparently save data gzipped in the database and uncompress at retrieval. Full description at my blog: [arnebrodowski.de/...Field-for-Django.html](http://www.arnebrodowski.de/blog/435-Implementing-a-CompressedTextField-for-Django.html)
Usage:
{% ifmodulo forloop.counter 4 0 %}
<!-- do something -->
{% else %}
<!-- do something else -->
{% endifmodulo %}
or
{% ifnotmodulo 5 3 %}
<!-- do something -->
{% else %}
<!-- do something else -->
{% endifmodulo %}
When the third parameter does not exist, it is assumed you're checking for values different than 0.
Ttemplates and filters for quoting e-mails in templates.
The `quoted_email` tag takes a template, renders it and quotes the result.
The `quote_text` filter puts one or more levels of quotes around the passed text.
This was a much better way of incrementing variables that only changed a small amount in name. deltab in #python also said I could have used tuples, but I'm not familiar with them yet, so I added this to a list of things to look into.
**Usage** (*in template*):
<img src="{{ MEDIA_URL }}2007/images/{% filter split:","|random %}theimage1.jpg,something2.jpg,thirdisthecharm.jpg{% endfilter %}" />
I decided to make it simple, because one template creator wanted to add random images to different places of templates. Creating something huge, like external image filename parsing was not necessary in this case.
month_ids is a list of months like this...
[('Apr07', 'April 2007'), ('Mar07', 'March 2007'), ('Feb07', 'February 2007')]
which can be used in a select box like this..
month = forms.ChoiceField(choices=(months))
If you work with Django like I do, you have a separate installation or Subversion check-out of Django for each of your projects. Currently each one of them eats 22 MB of disk space.
This utility hard-links all identical files between copies of Django. They can even be different versions or svn revisions, and you'll still be able to free a good amount of disk space.
Run this every now and then if you update installed copies of Django or add new ones.
This utility is available also [here](http://trac.ambitone.com/ambidjangolib/browser/trunk/hardlink_django_instances/hardlink_django_instances.py).
Does a digg url effect to a string, can be useful for using an item's title in the url,
from this:
.hi's., is (a) $ [test], will it "work"/ \
to this:
his_is_a_test_will_it_work
I understand this isn't a very well made script, I am not very good at string manipulation. But I would be happy if someone would recode it in a faster, more managable way. I recomend saving the rendering.
