No more phone lines… almost there
Sunday, December 17th, 2006As a software/data guy I always dream of abolishing physical boundaries so everything can be in software, virtualized. Besides a computer and a place to sit, what do you need to work?

Using Django admin’s search in your own views
Friday, December 8th, 2006In liu of a real fulltext search engine for Django, you may just want to use the same simple
search engine that Django’s admin uses. Unfortunately it’s not readily reusable, so you’ll have
to pull it out of the ChangeList.getqueryset
in django.contrib.admin.views.main.
def django_admin_keyword_search(model, keywords):
"""Search according to fields defined in Admin’s search_fields"""
if not keywords: return []
fields = model._meta.admin.search_fields
qs = QuerySet(model)
for keyword in keywords:
or_queries = [ Q(**{‘%s__icontains’ % field: keyword}) for field in fields ]
other_qs = QuerySet(model)
if qs._select_related:
other_qs = other_qs.select_related()
other_qs = other_qs.filter(reduce(operator.or_, or_queries))
qs = qs & other_qs
return qs
Alternate syntax for Django urlpatterns
Sunday, December 3rd, 2006Django’s urlpatterns variable has traditionally expected callbacks to be specified as strings, and extra arguments (commonly used with generic views) to be passed as a separate dict, for example:
info_dict = {
‘queryset’: Entry.objects.all(),
‘date_field’: ‘pub_date’,
}
urlpatterns = patterns(‘django.views.generic.date_based’,
(r‘^(?P<year>\d{4})/$’, ‘archive_year’, info_dict),
)
