Use in in django while preserving order
To Use
in
in Django while preserving order, you can use thein
filter provided by the Django template language.The
in
filter allows you to test if a value is contained within a list, tuple, or queryset.To use the
in
filter, you can simply use the following syntax in your Django template:value|in:list
.Here's an example:
{% if user.role|in:allowed_roles %} ... {% endif %}
In this example, the
in
filter is used to check if theuser.role
is included in theallowed_roles
list.This filter preserves the order of the elements in the list, ensuring that the containment check considers the sequence of elements.
By using the
in
filter, you can efficiently test for inclusion in a list while maintaining the order of elements.
