How do you limit list objects template side, rather than view side
DjangoDjango TemplatesDjango Problem Overview
One of the ways to limit objects is to add a limitation to a function like this
def ten_objects():
obj = Model.objects.all()[0:10] # limit to 10
return {'objects': obj}
However how do you achieve this inside a template rather than inside a view?
I know you can filter through objects within a template and limit characters but how do you actually limit the amount of objects displayed in a loop. Via the template. for example the following code will loop through all objects....
<ul>
{% for new in news %}
<li>
<p>{{ news.title }}</p>
<p>{{ news.body }}</p>
</li>
{% endfor %}
</ul>
How do I break the loop, say after the firs 3 objects/items. And how do I do it inside the template. Thanks in advance.

Solution 1 - Django
There is a slice
filter that you can use in templates. This works exactly the same as slicing within the view.
{% for new in news|slice:":10" %}
Solution 2 - Django
You want to use the slice template filter
Here's your example altered to use it:
<ul>
{% for new in news|slice:":3" %}
<li>
<p>{{ new.title }}</p>
<p>{{ new.body }}</p>
</li>
{% endfor %}
</ul>
