need for caching POST requests

Hi, I need to cache POST requests, too, on certain requests. The requests are not changing data, but imagine an XMLRPC service (that is based on POST requests only per spec anyway) uses functions, that always return the same like 2 + 2 SHOULD always return 4 :-) The site I have could use the

I've only 21 million rows in one of my tables and querying it is not a problem. First check that suggested function based index, it might help and you don't need to do anything. istartswith uses "not so good" format. We have got around it using additional field that is autopopulated, in your case

When migrating an existing db how do you create a proper join table for a ManyToMany field. I think I've got it mostly worked out except for the bit that looks like this in Django generated SQL: CREATE TABLE `blog_posts_authors` ( `id` int(11) NOT NULL AUTO_INCREMENT, `post_id` int(11) NOT

SQL modulus using QuerySet API

I have a model that has an IntegerField. I'd like to filter only the even integers. sqlite has a modulus operator so I can do: select * from mytable where my_int = my_int % 2 However, I'd like to use the QuerySet API to do this instead of resorting to SQL. Any ideas or hints? Thanks, Ryan

What might be useful is to figure out exactly what SQL Django winds up running then doing an "EXPLAIN " on that query in your DBMS from the command line. That will let you know what the backend is doing and what the performance considerations you should take are. On Tue, Jan 12, 2010 at 3:20 PM,

Re: Table with 4 Milions of rows

It really depends on how you're selecting the data from the database. If you're doing something that necessitates a full table scan(like in-DB ORDER BY) it will slow you down considerably. If you're selecting one row from the database by an indexed column, then the performance will be very fast

There are a few changes to the filter syntax if you want to get records that a certain user has access to. So lets say Cars are "namespaced". To get all the cars that are colored blue, you can still do this. Cars.objects.filter(color='blue') But to get all the cars that are color blue that only
