You can't nest tags like that.

There are various options - have you tried defining a string in your
view which is ":" + limit, and passing that to the template? Or
perhaps limiting news_list in your view?

Or, you could define a custom filter which takes a value and returns a
list sliced to that length. Something like (untested):
def slice_to_var(lst, lngth):
return lst[:lngth]

Template syntax question

2008-10-27 Thread Robocop 

So i'm looking to have an admin controlled news list, and one thing in
particular i'd like them to be able to control is how many headlines
are shown on the front page, and my current code is not doing that.

The line i care about is:

{% for New in news_list|slice:":{{limit}}"%}

where limit is some admin controlled variable that i'm certain is an
integer.  Is this possible?  Or is there just some error in my code
somewhere  that i have not seen?  Thanks!

You can use the slice filter:

{{product.title |  slice:":40" }}

or if you what the to truncate only at workbrakes, you can use the
truncatewaords filter:

{{product.title |  truncate:"5" }}
