I am running the following command to filter out empty values in my template:

{{ product.error_value1|default_if_none:"--" }}

This works well for Null Values but doesn't work if the value entered is "0". I wish the command 'default_if_null' existed. This way it would only check for null.

Any suggestions on an alternative?

If what you mean is you want things like "", [], 0, {}, etc to return True, you can use:

if not bool(x):

Or just simply:

if not x:
