TemplateSyntaxError at /parts/8051/
'for' statements should use the format 'for x in y': for t in
part.forum.thread_set.all |slice: ":5"

this is the offending line:
{% for t in part.forum.thread_set.all |slice: ":5" %}
any ideas ?

Is there a way to limit the number of element in the template
Hi,
I need to limit the number of elements I have to display on an index page.
Right now I do something like this in the template.
{% for p in part.object.all %}
...
{% endfor %}
Witch obliviously output all objects in the set.
In the view, I can do it this way:
Part.objects.all()[:5]
I would like to do this without doing the actual query in the view, am I
missing something ?
thanks

shemas evolution
I wonder what people are using *right now* to evolve their data ? I'm using this: # create a fixture with all data in the current db python manage.py dumpdata --indent=4 > initial_data.json # delete de database rm db.sqlite # edit the model # recreate db and reload data manage syncdb --noinput I know this is really rough... that's why I'm wondering if there any better solution. alex --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
