You need to add the loop controls extension for Jinja 2 to your app:
app.jinja_env.add_extension('jinja2.ext.loopcontrols')
Question
I am trying a simple continue
inside a for-loop
in Flask with jinja2
{% for num in range(0,10) %}
{% if num%2 == 0 %}
{% print num %}
{% else %}
{% continue %}
{% endif %}
and i get this error
TemplateSyntaxError: Encountered unknown tag 'continue'. Jinja was looking for the following tags: 'endif'. The innermost block that needs to be closed is 'if'.
Here is the jinja2 documentation that i followed... http://jinja.pocoo.org/docs/templates/#loop-controls
