specifying a model with a field computed from other fields

[Gavin]

Hi, I have a model in which there is a foreign key that I want created
using values from other fields. For example, I have a table `A`, with
fields `a`, `b` and foreign key `C`. I want to specify a final foreign
key field using the product `a`*`b` and value of `C`. I'm aiming at
being able to get between tables `A` and `C`.

What's a good way of doing this?

any thoughts much appreciated.

cheers,

Re: LDAP _without_ built-in Django user authentication

[Matt]

Is there any good documentation for implementing LDAP with Django?

The admin feature of Django is awesome and I'd love to use it, but in
addition to the need for LDAP my app will have to parse uploaded CSV
files in order to populate certain database tables simply because there
is far too much data to insert it one row at a time.  Therefore, I will
need a very customized admin interface -- at least for a few tables.
Ideally, I want to use the Django admin interface for 90% of the tables
that hold more basic info that could be entered manually, and then my
own custom interface for the CSV files.  Of course, the problem is I
would only be able to use LDAP (exclusively) for the non-Django admin
stuff.

Are there plans to allow for alternate authentication methods for the
Django admin by v1.0?

Try this in a template:

stringformat in template

[Rob Slotboom]

I tried to use stringformat within a template but without success.
This is what I want in 'normal' syntax':

return "%.2f" % total_amount

It returns a two decimal value.

But how to use it in the template???

Non DJango data types

[cajazzer]

I am looking for the easiest way to use POINT data types as supported
by Mysql (and Postgresql I believe) with DJango.  Along with this I
need to create a Spatial index on these columns.  Should I implement a
new type, or is there an easier way?

Doesn't DreamHost allow you to download your own copy of lighttpd and

Of course, if lighttpd needs root access, the standard plans at

lighttpd+FastCGI is the way to go for shared hosting, IMHO, but
Dreamhost doesn't offer lighttpd.

I've actually had pretty decent success with 

killall -USR1 the_process_you_want_to_die

This is supposed to signal the process it needs a restart so that the
next request in will be a process running your new code.

or use a little shell scripting, like

or something like that..

(i have to admit, the pkill solution looks simpler :))

You can also use django "build-in" method on your model objects like :

reqObs = something.get_list(order_by=('id',), limit=1)
if reqObs:
  firstOb = reqObs[0]

  Something like this perhaps...

  Maybe even .get_object() if it works with limit 1.

As the ID field is auto-incremented, the earliest ('first') record will
be the one with the lowest ID. In python, you can determine this by
pulling all records from the database and finding the one with the
lowest ID, or you can write a custom SQL query to do the same thing. I
don't know if Django currently has a built-in feature to let you do
this, though it is possible that the database will return the records in
creation order anyway (someone correct me here).

How to find out id of the first record?

[PythonistL]

Hi,
is there a way how to find out id of the first record in a table?
I will explain what I mean.
When I insert the first record into a table the id is 1.
when I insert next record, the id for this record will be 2.
But if I delete the first record, the id of the first record will be 2
.So, I need to find out the id of the first record.
Is it possible?

Django filter hack

[Andu]

Hi all,

One of the problems I faced when using Django's admin was the filter
part overlapped the table with data, when I showed lots of fields in
the admin listing.

I did a quick hack today and made it toggable. If you want to aply a
filter, show it. If not, leave it there and browse the listings.

I documented it here, and you can also see some images on how it looks:
