python - Getting a list of errors in a Django form

I'm trying to create a form in Django. That works and all, but I want all the errors to be at the top of the form, not next to each field that has the error. I tried looping over form.errors, but it only showed the name of the field that had an error, not an error message such as "Name is required."

This is pretty much what I'd like to be able to use at the top of the form:

{% if form.??? %}
    <ul class="errorlist">
    {% for error in form.??? %}
        <li>{{ error }}</li>
    {% endfor %}
    </ul>
{% endif %}

What would I use for ??? there? It's not errors; that just outputs the names of the fields.

form.errors is a dictionary. When you do {% for error in form.errors %} error corresponds to the key.

Instead try

{% for field, errors in form.errors.items %}
    {% for error in errors %}
...

Etc.
