Use in in django while preserving order

  1. To Use in in Django while preserving order, you can use the in filter provided by the Django template language.

  2. The in filter allows you to test if a value is contained within a list, tuple, or queryset.

  3. To use the in filter, you can simply use the following syntax in your Django template: value|in:list.

  4. Here's an example: {% if user.role|in:allowed_roles %} ... {% endif %}

  5. In this example, the in filter is used to check if the user.role is included in the allowed_roles list.

  6. This filter preserves the order of the elements in the list, ensuring that the containment check considers the sequence of elements.

  7. By using the in filter, you can efficiently test for inclusion in a list while maintaining the order of elements.
