Disable Template Cache Jinja2

flask, jinja2, python

Solution

You might want to set `app.config['TEMPLATES_AUTO_RELOAD'] = True` instead. Instead of disabling the cache, it will reload templates if the cached version no longer matches the template file.

Problem

I'm trying to disable Jinja2's template cache. I've done some looking around, and I've found that there's a `cache_size` parameter for jinja's environment. I'm using the following: ``` app.jinja_env = jinja2.Environment( cache_size = 0, loader = jinja2.FunctionLoader(utils.load_template) ) ``` I'm using a custom loader to dynamically load templates based on the domain (the app serves multiple domains). Unfortunately, using this, it looks like it overrides Jinja's default filters and builtin functions - using ``` @app.route(...) def page(): render_template('template') # from flask import render_template ``` I'm getting a `UndefinedError: 'url_for' is undefined` error. What's the proper way of doing this?
