Jinja2 template variable if None Object set a default value

Question

How to make a variable in jijna2 default to \"\" if object is None instead of doing something like this?

      {% if p %}   
        {{ p.User[\'first_name\'         


        

Answer 1

As another solution (kind of similar to some previous ones):

{{ ( p is defined and p.User is defined and p.User['first_name'] ) |default("NONE", True) }}

Note the last variable (p.User['first_name']) does not have the if defined test after it.
