Hello Yannick,
it's hard to answer your question because we miss to know what you're
trying to do. If you return a view with a json renderer the output will be
json, not html. If you return a view with a jinja2 renderer the output will
be html, not json. Jinja2 can iterate over a python list but not over a
json list, so it's hard to understand what you're trying to achieve here?
Json is for javascript so if you directly pass json to your html view it's
probably to init a javascript variable? Or you'd be better to call an API
to get that list from your javascript code.
To display json in your jinja2 templates, I'm a mako guy so I can be wrong,
I think it should be something like: {{myvariable|safe}}
OTOH if you want to return json but the result from the db is not what you
want to expose, you'll have to prepare the structure before sending it to
the view.
