The problem turned out to be an bug with an custom manager class based on
djorm_pgfulltext search mixin. I'd found an issue with it last week, and
patched in the development environment but forgotten to patch the other
machine.

On my development machine all is well. On the other machine the database

another app). I determined this with some print

I can't recommend either of those solutions specifically, but I have been

return path goes through the middleware (since it passes through once as a

I don't think anyone will be able to give you a good evaluation

handle 10k requests per second returning a simple "hello world"
response, or less than 10 if you are returning very large/difficult to
generate responses. It is

There are a few choices that I'm familiar with.

A method similar to what Anssi describes is what we use for local
caching of data that is too large to comfortably fetch from cache/
parse from file every time we need it. A Doing a lazy fetch with a
maximum age like that also helps with load times since it is only
fetched when accessed. Of
If you have a dataset that is too large to fit in memory comfortably,
the ability to pass a generator to an httpresponse means you can break
it up into multiple smaller queries (outside the template system
anyway):
def queryset_to_csv(queryset,delimiter=',',steps=500):

Just to clarify that last bit about a mapping on the model since it's
closest to what you originally described. Just pseudo-code, but you
can see the idea.

FIELD_DISPLAY={
'foo': ['a'],
'bar': ['b','c']
}
a = models.CharField()
b =
I may not be clear on what you are trying to accomplish, but maybe
something like

class Meta:
model=Model
def type_one_fields(self):
return [self.fields['a']] # Or use whatever criteria you want
for type_one fields.

There are also a few third-party apps that can assist you with the
form->query process such as this one:

Another clarification: It tells django to create an index on that
field when you run syncdb to create the tables for your apps. Adding
it to an existing model won't change anything by itself. If you
decide a field needs an index you can add it to the model definition,
and then you can use the
I would agree with Donald, and expand on that to say that an installer
would probably be best written in php for widest compatibility. A php
based installer would run outof the box on most webservers, and be
able to give a guided overview of the python/web environment setup.
It would easily be
The most elegant way I've seen specialized form rendering handled was
the use of template tags and filters. The django uni-form project is
a good example. By using the filter and template tags you gain full
access to all the form elements, and can do easy manipulation in
python, but leave the
Can you use the filesystem loader as the first template loader, then
set TEMPLATE_DIRS in settings.py to specify a template directory
outside any app? Use this location for all of your overrides, just
make sure the path is right... ie each app you override would have its
own subdirectory.

I haven't moved to 1.3 yet, but we do a few things with the template
source too so this is definitely of interest. It looks like most of
the template loaders define a load_template_source method
implementation that does return the source, except for the cached
loader. As a work around you could
You probably don't want to cache changes. Or if you do, it would be
better done elsewhere (like a caching raid controller/w battery on
your database machine). The usual cache patterns I've seen are:
1) Fetch from database
2) Store in cache with a reasonable timeout to that changes are
reflected
Depending on the resolution and maximum duration, you could just use
an integerfield containing either the number of seconds or minutes,
and then recreate it. That way you can also base queries off of the
value, which you can't do with just a pickle field. Of you could
subclass the integerfield
I'd like to see you model structure, but based on what I think it is:

I don't think it's necessarily a choice between learning php or
learning python. Most programming languages are fairly similar in
concept, and once you've mastered one it's reasonably easy to pick up
a new one. Python is a great language, but I think it's especially
great as a first language.
I'll second the use of something like LXC (new to me) or OpenVZ (what
we use), allowing you to run/test multiple distros at once. If you
want to try debian (or pretty much any linux distro), download a
container skeleton for it and install in a few seconds. I've used
virtualbox/kvm, but I found

What you are feeding HttpResponse is the
**filters is python for expand the dict 'filters' into keyword

If you just want a simple user search (which seems to be what you are
asking for), it really depends on your models - but a basic approach I
usually use is to define a django form to use for the search, and
instead of defining a save method, make a method that returns a
queryset. As an off the top
