Hello,
I am using your wonderful jinja2 (v2.2.1) template system into django
(v1.1).
It is really fast and I like it a lot.
Nevertheless, I have some problem to debug templates :
If I make some errors into a template (bad tag, bad filtername, bad
end of block), I do not have at all information about this error :
In a django view, I write this :
from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('main', 'templates'))
def jinja(req):
template = env.get_template('jinja.html')
output=template.render(myvar='hello')
return HttpResponse(output)
jinja.html :
{{myvar|notexistingfilter()}} Jinja !
Notice, I put on purpose an non existing filter to generate an error :
I was expecting something like "notexistingfilter() not defined", but
I got only :
Traceback (most recent call last):
File "/usr/local/lib/python2.6/dist-packages/django/core/servers/
basehttp.py", line 279, in run
self.result = application(self.environ, self.start_response)

File "/usr/local/lib/python2.6/dist-packages/django/core/handlers/
base.py", line 154, in handle_uncaught_exception
return debug.technical_500_response(request, *exc_info)
File "/usr/local/lib/python2.6/dist-packages/django/views/debug.py",
line 40, in technical_500_response
html = reporter.get_traceback_html()
File "/usr/local/lib/python2.6/dist-packages/django/views/debug.py",
line 84, in get_traceback_html
self.get_template_exception_info()
File "/usr/local/lib/python2.6/dist-packages/django/views/debug.py",
line 117, in get_template_exception_info
origin, (start, end) = self.exc_value.source
TypeError: 'Template' object is not iterable
I do not get the template filename where the error occured, no
information about the error itself, so it is very difficult to debug
jinja2.
What should I do to have more debug information ?
Thank you in advance,
Eric
