Hi people,
Right now I'm using TG 2.2.0 and I've tried TG 2.2.2 but I have problems during template parsing.
I use Jinja2 (2.6) and use_dotted_templatenames = False and don't use .jinja extension for templates, but .html, .js, etc.
The problem is that everything is escaped so if I have something like this:
import simplejson as sj
class AController(BaseController):
@expose('foo/bar/my_template.html')
def my_template(self):
something = sj.dumps(dict(foo='foo', bar='bar'))
return dict(something=something)
Then inside the HTML template (foo/bar/my_template.html)
<html>
<body>
<script>
var something = {{something}};
console.log(something.foo); // 'foo'
console.log(something.bar); // 'bar'
</script>
</body>
</html>
This ain't work because {{something}} is escaped to be HTML-suited instead of its "raw" format.
Same thing happens with the default error page. Instead of
We're sorry but we weren't able to process this request.
I get
<p>We're sorry but we weren't able to process this request.</p>
Does anybody know what's going on?
I have say that this happen with an existing app, upgrading TG2 version from 2.2.0 to 2.2.2. I simply use another virtual environment.
Thanks
Regards,
León

Starting from 2.2.1 Jinja has autoescaping enabled by default like all the other template engines did. This makes so that TurboGears has a consistent behavior of escaping independently from the engine used.
You can update your code using markupsafe.Markup to mark parts that should not be escaped or explicitly disable the escaping using a before_config hook to change base_config['pylons.app_globals'].jinja2_env.autoescape to False.
