How to dynamically select template directory to be used in flask?

Question

By default flask uses template files stored in \"template\" directory :

/flaskapp
    /application.py
    /templates
        /hello.html

There is also the possibility to overwrite Jinja loader and set the paths where Jinja will look for the templates. Like:

my_loader = jinja2.ChoiceLoader([
        app.jinja_loader,
        jinja2.FileSystemLoader(['/flaskapp/userdata', 
                                 '/flaskapp/templates']),
    ])
app.jinja_loader = my_loader

Directories are arranged in the order where Jinja needs to first start looking for it. Then from the view you can render user specific template like this:

render_template('%s/template1/hello.html' % username)

where username you can dinamically change in the view. Of course you can also there choose which template (1 or 2) to render. But basically what you really miss is this custom Jinja loader with the custom paths.

Hope that helped or gave the ideas :)
