Re: In my django web app i wannt show time in user timezone

[Vovk Donets]

>From docs: "...there’s no equivalent of the Accept-Language HTTP header
that Django could use to determine the user’s time zone automatically.
Instead, Django provides time zone selection functions
<https://docs.djangoproject.com/en/dev/ref/utils/#time-zone-selection-functions>.
Use them to build the time zone selection logic that makes sense for you."

There is two paths.
First. You can store time on the server in UTC, detect user timezone and
then do conversion to this timezone on your backend. You can also look at
https://docs.djangoproject.com/en/dev/topics/i18n/timezones/#localtime
Second path is that you can do time conversion on the frontend using
whatever you like JS library to do this work. But in both cases you should
determine users timezone yourself or ask user in which TZ he is.

Re: Comments form customization

[Vovk Donets]

It's not really great solution, but maybe it will give you a hint: you can
add/remove fileds to the form on the fly. And for not logged in users show
all fields, but for authenticated only subset of the all form fields.

Re: how to use asyncore socket in django views.py

[Vovk Donets]

To accepts socket connetction you need always listen some port. Othewise
you will be trying hit a bulls eye when sending data to this port (if you
would listen port only when view was called) View is a function it's not a
webserver that runs and listen to port.
You need to decouple working with sockets from view and place it somewere
outside django

Your way is right, nothing wrong wth storing templates in app directory.
For this purpose django even has special app loader, wich loads templates
stored in the app directory.

And this way your app would be closer to "just plug in and use"

As for me, i'm deciding where to store templates basing on app or project
requirements.

you can do it by inserting "modelAvalue__description" in the admin.py in the

class modelBAdmin(admin.ModelAdmin):
list_display = ( 'id','modelAvalue__description', 'description')
admin.site.register(modelB, modelBAdmin)

Re: Problem with overriding the default Django admin page.

Django dev server restarts itself, but sometimes you have to manually
restart it.
Well, if you specify paths right and create there is a directory nothing
would go wrong:

TEMPLATE_DIRS = (
"/templates/",
}
and your project for example is here "/var/www/project/" than you go to this
dir and in the dir "templates" create dir "admin" and place here thoose
admin templates that would replace default admin templates. As i have done
it many times if it is done right things works from the start.

for debugging you can delete default admin templates and when Django spills
error that template does not exist's look at path's in traceback where
django searched templates
it can help to understand problem better

If i understand you correctly then If you want some aditional information

look in docs.

To get all categories of the Video item u can do:
video.category.all()

About your wish to use method of get_surname to sort queryst - i think it's
not possible to do in this ORM.(well, i'll be happy if im wrong)
But you can sort queryset after you get it or you could subclass
models.query.QuerySet to add you own functionality like
 Item.objects.filter(...).order_by_surname(item.get_surname()) or smth like
this

You must specify in the TEMPLATE_DIRS path to the dir where templates were

So
TEMPLATE_DIRS = (

)
should work, coz'  "In order to override one or more of them, first create

if i understand you correctly:
in settings.py theres is a lines
# Absolute path to the directory that holds media.
# Example: "/home/media/media.lawrence.com/"
MEDIA_ROOT = /absolute/path
# URL that handles the media served from MEDIA_ROOT.
# Example: "http://media.lawrence.com;
MEDIA_URL = "/media/"
**so in a template you need specify path to media like this:
{{MEDIA_URL}}path/to/my/cript.js
But keep in mind that this variable must be passed into template via context
processor ("django.core.context_processors.media", ) or directly from view.
As for regular design flow read django manual. There is to much to say in
one letter.
