How can I count the messages coming from a view inside a template?

Question

I'm using Django's messages framework to pass messages from my view functions to my templates. I want a template to contain some HTML only if the number of messages is greater than 1. Is there a way to do this?

I've tried the following:

{% if messages.count > 1 %}

    <html for multiple messages>

{% else %}

    <html for just one message>

{% endif %}

But messages.count doesn't seem to exist.

messages has a __len__ function, so it can be used with the length template filter:

{% if messages|length > 1 %}

    <html for multiple messages>

{% else %}

    <html for just one message>

{% endif %}

See https://docs.djangoproject.com/en/2.2/ref/templates/builtins/#length
