Re: low-level cache & pagination
Alright, I think I answered my own question. It seems the current
RequestContext is a little messed up and not only requests cache to be
remade, but also crashes runserver upon more than 1 request.

low-level cache & pagination
I have a large query that is ran and takes about 50 seconds to
completely and is pretty resource intensive. So what I have done is
cached it into a key via cache.set('my_query_results', results, 300)
The problem is that I also use pagination which results from this
query. So when navigating to ?page=2~ it should in theory just re-use
the cache and output page 2's data. But it doesn't. What it does is re-
run and re-cache the entire query again. I'm guessing that this is due
to the 'request' (MyView(request) is changing (?page=2).
Is it possible to override this? Or am I just doing something this
whole thing wrong?
Thanks

Simple input forms which show more than one row - easy/possible in django?
I want to create a simple data entry form on a web page that shows all the columns of a database across the page (there aren't many columns, they will fit!) and a number of rows down the page. I.e. I want a data entry form that looks like MS Access 'tabular' format, as follows:- Col1Row1Col2Row1Col3Row1Col4Row1Col5Row1 Col1Row2Col2Row2Col3Row2Col4Row2Col5Row2 Col1Row3Col2Row3Col3Row3Col4Row3Col5Row3 Col1Row4Col2Row4Col3Row4Col4Row4Col5Row4 Col1Row5Col2Row5Col3Row5Col4Row5Col5Row5 Col1Row6Col2Row6Col3Row6Col4Row6Col5Row6 New DataNew DataNew DataNew DataNew Data Can django do this easily in a 'ready made' sort of way or do I have to actually create the form and all its fields? -- Chris Green -- You received this message because you are subscribed to the Google Groups "Django users" group.

Beginner a bit lost - need some pointers please
I'm an experienced programmer (started around 1971 or so!) and I've done lots of things over the years, much of my background is in Unix (Solaris). In the last few years I have done quite a lot of web related stuff. I'm trying to get my mind round django. I have it installed on my unbuntu server, it works, I've worked through tutorials 1 and 2 and a bit of 3. I can get the admin screens up and the basics of the polls example work. However two rather basic things still elude me:- Where/how do I actually start creating the top level/page of a web site? Do I just open vi and create some HTML and embed django code? That seems unlikely but I can't see anywhere that tells me what the code that creates a django site looks like and/or where it resides. An actual example of a two or three page working django based web site would be a huge help. I can't see anywhere that seems to tell me the issues involved with moving from using the built in web server to using apache2 (or whatever, I have apache2 on my system). I know that in a few days time when I have got over the initial hump all the above will seem trivial so sorry to ask, but at the moment I'm feeling a bit lost! :-) -- Chris Green -- You received this message because you are subscribed to the Google Groups "Django users" group.

A quick glance seems to raise some of the same questions, there are lots of code snippets in there but it's not *very* clear where they all live or even whether one has to write them or they're generated by django. It does seem a bit clearer at a second reading though so I suspect it will all become clear eventually. -- Chris Green -- You received this message because you are subscribed to the Google Groups "Django users" group.

I realise that configuring apache2 to do all this involves more work, what I wanted was the steps required to go from a working django project under the built-in server to one that works under apache2.
