If you have a solution that is fine.
But if you did the business logic in the view, there is no need for
{%- if interests|length > 0 %} and you would simply return your
dictionary values while rendening as a variable that contains actual
values
and no need for the if statement which provides the extra carriage
return
{% for event, interests in report.items %}
{{event}}
