Re: DB: working with databases

[Uros Trebec]

You can upgrade the "inspectdb" result with Django Autoadmin (
https://github.com/bancek/django-autoadmin ) which generates necessary
basic AdminModel classes on the fly, without the need for manual
definition and/or Django-specific DB tables (auth, for example).

This way you can be up and running even faster.

Re: logging django errors also on the server

Take a look at Sentry: http://readthedocs.org/docs/sentry/

It works pretty well, uses polling to update the log view, can track
multiple sites with separate Sentry Server, etc.

Good luck,

Re: Media files not served automatically anymore in 1.3?

Somehow (I don't remember setting this up) I use

Re: any recipes for 'live' updating a site with model changes

[Uros Trebec]

Hi,

for your DB migration problem you should take a look at South[0].
As for your 'under maintenance' step you will have to do that manually
or use some kind of a tool to automate it, as well as other steps for
the upgrade. There are many such tools, Fabric[1] and Chef[2] being
two of the most popular.

You should probably take a look at:
* manage.py inspectdb command
https://docs.djangoproject.com/en/1.3/ref/django-admin/#inspectdb

* Multiple DB:
https://docs.djangoproject.com/en/1.3/topics/db/multi-db/


If that fails, ask away.

Re: Model translation

[Uros Trebec]

Did anyone try "django-nani"?

https://github.com/ojii/django-nani

I'm giving it a go with my multilingual project and it kind of works.
The translating part works nicely, the biggest issue I have is the
limited AdminModel functionality (
http://django-nani.readthedocs.org/en/latest/public/admin.html#modeladmin-apis-not-available-on-translatableadmin
).

But other than that, looks promissing.

Re: Decimal fields have landed on trunk: rename your FloatFields

[Uros Trebec]

Hi guys!

I can't believe how fast are you developing Django! I had a 2 days old
checkout and was looking at current model documentation... and the
validation kept saying "'module' object has no attribute
'DecimalField'".
I was ready to give up and take a nap to clear my mind when I thought
I should check the Groups... and here it is, a change one day old!

Congrats on to all developers for progress this fast and to all users
that can keep up with all the changes :)

That might be a good idea. It seams that PgSQL scales 200% percent
better than MySQL (when using multiple processors/cores/machines.

Take a look at this test ( http://tweakers.net/reviews/646/1 ). It's
basically a CPU comparison but using DB performance on real live
example as tests. Here's the scaling properties (
http://tweakers.net/reviews/646/15 ), but I recommend reading the whole
article.

Re: Re: Django + FastCGI Problems

[Uros Trebec]

I am sorry to report that this method does NOT work on my
machine/account. I've tried different users (on the same machine) and
it does not work. Symptoms are the same.

I guess it's just my machine the one that is F00! And they refuse to
move my account to another one. :(

Anyone knows about any concrete alternative hosting that is production
stable for Django and offers reasonable prices (sub $10/month), disk
space (5-10GB) and bandwidth (250GB+) with multiple domain/site
hosting?
(I tried site5.com, but they would not accept my Visa Electron or
PayPal payment :( )

Lets hope so! :)

OK, I've built lighttpd and got it running with the basic

Now, how do I get Apache to redirect all requests to my lighttpd server?

Any suggestions?

Hi, I'm sorry for not noticing your post as I'm rather busy with exams
etc.

Anyway, I think I know where's the problem. I noticed that I forgot to
mention that you need to add 'django.contrib.history' to INSTALLED_APPS
in your application's "settings.py" file.

After this I believe everything should work as described on the Wiki
page. Please note, there is no automatic compare/merge/revert mechanism
at the moment, so you need to do that on your own.

If you have any specific question about the usage, bug report or
feature request please feel free to post in this group or to me

So, what I'm trying to do is to modify contrib.history.models.ChangeLog
(full-history branch) so its "parent" can link to different models, not
just one (current version). This way I can use only one table to store
any object (I need to know to which model and row does it belong).

I'll keep you posted if I can't make it work, ok?

Hi everyone!

I'm trying to figure out how to use django.contrib.contenttypes. There

only find this [0] blog post from which I can't get anything useful
from.

Does anyone know how to use this thing?
