How to perform query filtering in Python Django templates?
To perform query filtering in Python Django templates, we can create a template tag that calls filter.
For instance, we write
@register.filter
def in_category(things, category):
return things.filter(category=category)
to create the in_category tag function that calls things.filter to filter by category.
Then we write
{% for category in categories %}
{% for thing in things|in_category:category %}
{{ thing }}
{% endfor %}
{% endfor %}
in our template to use the in_category tag with the category as the value of the category parameter.
