I'm building an admin for Flask and SQLAlchemy, and I want to pass the html for the different inputs to my view using render_template. The templating framework seems to escape the html automatically, so all <"'> are converted to html entities. How can I disable that so that the html renders correctly? ...

I didn't find a good comparison of jinja2 and Mako. What would you use for what tasks ? I personnaly was satisfied by mako (in a pylons web app context) but am curious to know if jinja2 has some nice features/improvements that mako doesn't ? -or maybe downsides ?- ...
I have two for loops, both alike in dignity. I'd like to have a counter incremented during each inner iteration. For example, consider this template: from jinja2 import Template print Template(""" {% set count = 0 -%} {% for i in 'a', 'b', 'c' -%} {% for j in 'x', 'y', 'z' -%} i={{i}}, j={{j}}, count={{count}} {% set count =...

Hi I've been trying to create an extension for jinja2 that would join multiple items with a separator, while skipping items (template fragments) that evaluate to whitespace. There are several of those fragments and you never know in advance which ones will be non-empty and which ones will. Sounds like a trivial task, but I had real har...
Converting from Django, I'm used to doing something like this: {% if not var1 %} {% endif %} and having it work if I didn't put var1 into the context. Jinja2 gives me an undefined error. Is there an easy way to say {% if var1 == None %} or similar? ...
I am a very young programmer and I am trying to do something in Python but I'm stuck.

I want to make one template (B) inherit from the other (A), i.e. I have {% block body %}{% endblock %} in A, and I want to make the body block be ...
