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

To avoid throw a exception while "p" or "p.User" is None, you can use:

{{ (p and p.User and p.User['first_name']) or "default_value" }}
