Django Templating: how to access properties of the first item in a list

问题

Pretty simple. I have a Python list that I am passing to a Django template.

I can specifically access the first item in this list using

{{ thelist|first }}

However, I also want to access a property of that item... ideally you'd think it would look like this:

{{ thelist|first.propertyName }}

But alas, it does not.

Is there any template solution to this, or am I just going to find myself passing an extra template variable...

回答1:

You can access any item in a list via its index number. In a template this works the same as any other property lookup:

{{ thelist.0.propertyName }}

回答2:

You can combine the with template tag with the first template filter to access the property.

{% with thelist|first as first_object %}
    {{ first_object.propertyname }}
{% endwith %}

回答3:

If you're trying to access a manytomany field, remember to add all, so it will look like object.m2m_field.all.0.item_property
