No, you can't do that with the basic template language - it's
deliberately restricted to a few common operations. However you can
very easily define a custom template filter to do this. In your
application directory, create a subdirectory called templatetags and
put in a blank __init__.py and a file called (eg) mytags.py containing
something like:
from django import template
register = template.Library()
@register.filter
def startswith(val1, val2)
return val1.startswith(val2)
Then in your template:
{% load mytags %}
{% if item1|startswith:item2 %}
...
{% endif %}

Re: little problem with the django template language
I guess it was a little confusing how I formulated my problem. I just
try again. Sorry for that.
In Python what I want to do would look like the following:
item1 = '/test/something/'
item2 = '/test/somethingelse/'
if item2.startswith(item1):
do_the_trick()
Now since Django has this nice template language I need to do
something like that:
{% ifstartswith item2 item1 %}
...do the trick
{% endifstartswith %}
is that possible?

Re: little problem with the django template language
yes they are strings,
yes in python if you do
if item1:
pass
it will evaluate the string as a true/false depending on existance.
however, comparing two strings for equality... checks if they are
equal.
{% if item1 %}
{% if item2 %}
blah
{% endif %}
{% endif %}

Re: little problem with the django template language
Hi,
If you are trying to compare url string then use
request.path
which will give you URL and split by "/"
is that work for you?
Cheers!
