Thanks for your help but I think that understand how template works.
My menu is drop down menu with menu items which comes from variable
{{ for menuitem in myvariable }}
{{ menuitem.title }}
{{ endfor }}

and myvariable is in my view:
myvariable = Item.objects.all()

So if I extend base.html menu is there, but menu items are not,
because "myvariable" come from the "view". So seems that I need
"myvariable = Item.objects.all()" in every view on the site. Which
also means that I need to repeat myself about 20 times. I was
wondering is there any solution to include myvariable in settings file
or something? Also is there any solution to extend flatpage view with
myvariable?

Thanks



http://docs.djangoproject.com/en/1.2/ref/templates/api/#subclassing-context-requestcontext

You can write ur own context processor, witch variables will be accessible  
across all templates.


Example code:
content.py file:

from nml.newsletter.forms import NewsletterForm

def newsletter_form(request):
"""
Creates unbound newsletter form
"""
nl_form = NewsletterForm()
return {'nl_form' : nl_form}

in settings.py:


TEMPLATE_CONTEXT_PROCESSORS = (
"django.contrib.auth.context_processors.auth",
"django.core.context_processors.debug",
"django.core.context_processors.i18n",
"django.core.context_processors.media",
"django.contrib.messages.context_processors.messages",
'static_content.newsletter_form',
)

I used that once in root template, but it is rendered with any view that  
extends my root template

Re: home page menu view variables cross every view?

[Vasil Vangelovski]

You can use your own template for flatpages, see
http://docs.djangoproject.com/en/dev/ref/contrib/flatpages/?from=olddocs#flatpage-templates
Just make that menu a separate template and include it wherever you want. Of
course your flatpages template and your other templates can inherit from the
same base where the menu is included.

I  don't know what you mean by  "place
these variables ( db queries)"? Anyway if your menu is generated from a
database and it won't change often it's a good idea to wrap such template
code in a cache tag, especially if you make manny queries to generate that
menu.

Hi,

whats about extending? for example base.html?

Could this be a way to solve your problem?

http://stackoverflow.com/questions/671369/django-specifying-a-base-template-by-directory

A live example and pretty cool explanation can be seen in this screencast(s):
http://showmedo.com/videotutorials/series?name=PPN7NA155
(The mentioned project is not available anymore but the principles are pretty
clear explained. I think extending is shown in episode 3.)

good luck

home page menu view variables cross every view?

[Goran]

I'm Django novice and I want to have some menu (top menu) which have
some dynamically populated items. So inside home page view I have some
variables to get these menu items. But because it's top menu I need it
on every page on the site and i have about 20 views.  So I'm place
these variables ( db queries) in every view on the site. It works
except on the Flatpages because I can't find a way to extend Flatpage
view with these variables. Now I have two questions:

1. How can I extend FlatPage view to get these menu variables on the
flatpages.
2. Am I miss something? What's happen with D.R.Y. if I need to place
the same variables on the every view and repeat myself 20 times?

Any advice?
Thanks
