'if' statement in jinja2 template

Question

I'm trying to write an if statement in jinja template:

{% for key in data %}     {% if key is 'priority' %}         <p>('Priority: ' + str(data[key])</p>     {% endif %} {% endfor %} 

the statement I'm trying to translate in Python is:

if key == priority:     print(print('Priority: ' + str(data[key])) 

This is the error i'm getting:

TemplateSyntaxError: expected token 'name', got 'string'

Answer 1

Why the loop?

You could simply do this:

{% if 'priority' in data %}     <p>Priority: {{ data['priority'] }}</p> {% endif %} 

When you were originally doing your string comparison, you should have used == instead.

Answer 2

We need to remember that the {% endif %} comes after the {% else %}.

So this is an example:

{% if someTest %}      <p> Something is True </p> {% else %}      <p> Something is False </p> {% endif %}
