Optional ImageField (Django)

Question

I'm having a problem with an ImageField in one of my models. It is set to blank=True, null=True (it is optional.)

When I loop through a list of objects and use object.thumbnail.url, I get "Caught an exception while rendering: The 'thumbnail' attribute has no file associated with it."

This only happens if no thumbnail has been uploaded, obviously.

Does anyone have any ideas on the best way to deal with that?

Answer 1

Turned out it was as simple as:

{% if object.thumbnail %}
    <img src="{{ object.thumbnail.url }}" />
{% endif %}
