django - Unrelenting TemplateSyntaxErrors -
update #7:
i removed first line , put in place second line below copied jinja2 link jinja2 install docs. still error below.
# google.appengine.ext.webapp import template jinja2 import template file "/users/brian/googleapps/youpoll/views.py", line 271, in self.response.out.write(template.render(path, template_values)) nameerror: global name 'template' not defined info 2012-07-08 22:43:53,053 dev_appserver.py:2952] "get /?id=testbschott http/1.1" 500 this appengine worked little while ago non-django code in template files.
furthermore, if execute following code in gae interactive console, works, though contains {%- if ... -%} code think unique jinja2, not django.
from jinja2 import template template = template('{%- if true -%}hello {{ name }}!{% endif %}') print template.render(name='john doe') update #6:
ok, found variable template being defined. it's below.
jinja_environment.filters['datetimeformat'] = datetimeformat class basehandler(webapp2.requesthandler): @webapp2.cached_property def jinja2(self): return jinja2.get_jinja2(app=self.app) def render_template( self, filename, template_values, **template_args ): template = jinja_environment.get_template(filename) self.response.out.write(template.render(template_values)) update #5:
here imports in views.py:
import jinja2 import os import webapp2 import logging import datetime google.appengine.ext import db google.appengine.api import users google.appengine.ext.webapp import template google.appengine.ext.webapp.util import run_wsgi_app google.appengine.api import images # jinja2 import environment, packageloader models import qa, pq template_dir = os.path.join(os.path.dirname(__file__), 'templates') jinja_environment = \ jinja2.environment(loader=jinja2.filesystemloader(template_dir)) my use of template_values below in code posted. 2 of imports mention webapp, not webapp2. if change first 1 webapp2 error.

file "/users/brian/googleapps/youpoll/views.py", line 272, in self.response.out.write(template.render(path, template_values)) nameerror: global name 'template' not defined info 2012-07-08 18:30:52,733 dev_appserver.py:2952] "get /?id=testbschott http/1.1" 500 do see can do? did give info need?
update #3: if remove these 5 jinja2 sequences/phrases html form works fine. there no syntax error these 5 sequences/phrases. used work fine. , have added below in first update traceback includes django, although not using django -- jinja. other error making?
i have included @ bottom html page prior removing sequences/phrases above.
1
{% choice in p.choices -%} {% if not loop.first %} ,{% endif %} {% if loop.last %} or {% endif %} {{ choice }} {%- endfor %}. 2 {% choice in p.choices %} {% if not loop.first %} ,{% endif %} {% if loop.last %} or {% endif %} {{ choice }} {% endfor %}.
3
{{ q.answers|sum() }} 4
q.date|datetimeformat('%d-%m-%y') 5
q.modified|datetimeformat('%d-%m-%y')
end of update #3
this phrase occurs before errors, works fine.
{% if p.purpose %} </p> <p> purpose of questionnaire {{ p.purpose }}. </p> {% endif %} but next phrase throws error (apparently).
{% choice in p.choices -%} {% if not loop.first %} ,{% endif %} {% if loop.last %} or {% endif %} {{ choice }} {%- endfor %}. next error.
update #2: if revise "errant" 'for' statement, removing space control '-'s, system still moves on next error below, , yet '-'s not errors.

btw, traceback mentions django often, when using jinja2, suppose irrelevant.

wooble answered question commenting rid of google.appengine.ext.webapp import template , replace from jinja2 import template, had error may have caused original problem. used self.response.out.write(template.render(path, template_values)) instead of self.render_template('table.html', template_values ) @ 1 point.
the key problem gae using django when thought using jinja2 , wooble keyed on fact mentioned casually in original question.
(so hope wooble gets credit answer.)
