What is the equivalent of "none" in django templates?

I want to see if a field/variable is none within a Django template. What is the correct syntax for that? This is what I currently have: {% if profile.user.first_name is null %} <p> -- </p> {% elif %} {{ profile.user.first_name }} {{ profile.user.last_name }} {% endif%} In the example above, what would I use to replace "null"?
None, False and True all are available within template tags and filters. None, False, the empty string ('', "", """""") and empty lists/tuples all evaluate to False when evaluated by if, so you can easily do {% if profile.user.first_name == None %} {% if not profile.user.first_name %} A hint: @fabiocerqueira is right, leave logic to models, limit templates to be the only presentation layer and calculate stuff like that in you model. An example: # someapp/models.py class UserProfile(models.Model): user = models.OneToOneField('auth.User') # other fields def get_full_name(self): if not self.user.first_name: return return ' '.join([self.user.first_name, self.user.last_name]) # template {{ user.get_profile.get_full_name }}
