Re: Optimistic Locking
How about rewriting save method complately and make additional condition in WHERE clausule like this: UPDATE ... WHERE id=666 AND mtime=object_mtime Checking number of updated rows would give you information about success and would guarantee that there is no data manipulation between mtime check and save. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: website side component processing
I just got new idea that maybe I should use custom template tags to call processing of all common subpage components. That would be even more efficient and flexible, because I could have many different premade templates to choose from in admin panel and each of them having different set of components. Whad do you think? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

website side component processing
I'm quite new to django/python (migrating from php). I've been developing cms-like web applications for years now. Now I'm trying to create quite advanced CMS using django. Lately I moved from doing simple tests in django to tearing other peoples django apps into pieces to get the idea of best practices when using django. The thing I dont know is where do I put code for processing side (left/ top/right/foot) componets of webpage. Simple examples show just how to display content of one component into what I'd "center content area". But where should I process small side components (like box of latest news leads and such) which should be shown on every subpage. I'm sure there is more proper way of doing this other way than: def my_view_1(request): process_side_subpage_components() # below process all stuff formy_view_1() def my_view_2(request): process_side_subpage_components() # below process all stuff formy_view_2() etc... In php I've writtent small OOP framework for myself and it basicly worked like this: * AbstractPage - class defining page methods, basic behaviour and convention of use. (common for each project) * ProjectPage extends AbstractPage - processing all subpage side components. (customized for each project) * ComponentViewPage extends ProjectPage - processing all data for currently displayed component. (common or customized depending on project) And when "ComponentViewPage" was being processed, all the common side components were automaticly processed too because this page inherited its behaviour from ProjectPage. What would be most elegant and most efficient way to do that in Django? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Best practice for implementing multilingual content in template
I think that better idea would be doing something like that (I'm using
even more complicated models myself):
class Page(models.Model):
#parent page in tree of pages
parent = models.ForeignKey('self', related_name="children",
blank=True, null=True)
slug = models.SlugField(unique=True)
#name for admin page listing
name = models.CharField(max_length=255)
#short description for admin page listing
descr = models.TextField()
#relative order of silblings
order = models.IntegerField()
author = models.ForeignKey(User)
class Content(models.Model):
#melongs to which page
page = models.ForeignKey(Page)
author = models.ForeignKey(User)
#version in what language
lang = models.CharField(max_length=3)
title = models.CharField(max_length=255)
content = models.TextField()
COMPONENTS = (
('article', 'Article'),
('news', 'News'),
('partners', 'Partners'),
)
component = models.CharField(max_length=50, choices=COMPONENTS)
#is page published for this language version
published = models.BooleanField()
#template = models.ForeignKey(Template)
We got relational database so lets use relations to be more efficient
and have less data redunddancy.
To explain a bit more class Page has one row per each page and has
related as many rows in Content class as the number of languages. Just
keep current language in session and use it to filter content rows to
get the one you need. All the data that is shared among instances of
page for each language is kept in Page class (less data redundancy).
All the data that differs between languages is kept in Content (we
read from database to memory only the data for one language - thats
efficiency).
Hope that helps :)

Tutorial03: question about efficiency
theres line of code in tutorial:
Poll.objects.all().order_by('-pub_date')[:5]
this gives 5 Poll objects. I wonder if this is efficient way of
getting them? Does django get all rows first and then sort it and then
slice it to get only 5? Or is it optimized somehow. The question is if
its simplified for the tutorial and inefficient or this is the right
way to do it?

I also use PyDev, but I run it on windows and use Remote Site Explorer to modify files directly on linux virtual machine. This way I cant do remote debugging.

Re: Django Tutorial02 / TEMPLATE_DIRS
> So, though the settings.py you posted has TEMPLATE_DIRS with your '/ > var/www...'directory listed, the one you are running with has no > TEMPLATE_DIRS. Yes I've noticed that, but I use settings.py listed above. Django uses db configuration from that file and other things too. Somehow TEMPLATE_DIRS gets cleared or filtered. for example if I run python manage.py shell from project dir and inspect settings module it is empty. I'm kinda new to Python and Django, so I may actually do some stupid mistake on the way. I'm getting frustrated enough to convinve myself to use pdb to run that code step by step. I dont know how to use pdb and it scares me yet Still considering installing Django on windows and trying to debug it through Eric or SPE (but since winxp is different platform I can get different issues and that holds me off it). BTW if it does matter I've setup Ubuntu (just shell, no X-Windows) on VMWare and using it as development server from windows xp. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django Tutorial02 / TEMPLATE_DIRS
Trying to solve the problem I added following code to settings.py:
ALLOWED_INCLUDE_ROOTS = (
'/var/www',
)
but it didnt help.
I skipped this error for a bit and continued with tutorial and heres
