I'm running into a problem when I'm trying to use Django's template system in a standalone application. Previously, in Django 1.4, I didn't have this problem.
As described at configuring the template system in standalone mode <https://docs.djangoproject.com/en/1.7/ref/templates/api/#configuring-the-template-system-in-standalone-mode>, I first configure the settings of Django and then call one of the template loaders. However, I get an AppRegistryNotReady error: In [1]: from django.conf import settings In [2]: settings.configure(**{'TEMPLATE_DIRS': ('/home/oliver/projects/autodelayv3/templates',), 'TEMPLATE_LOADERS': ('django.template.loaders.filesystem.Loader',)}) In [3]: from django.template.loader import render_to_string In [4]: render_to_string('webform.html', {'first_name': 'Oliver'}) --------------------------------------------------------------------------- AppRegistryNotReady Traceback (most recent call last) <ipython-input-4-d2451b904f1a> in <module>() ----> 1 render_to_string('webform.html', {'first_name': 'Oliver'}) /home/oliver/.virtualenvs/base/local/lib/python2.7/site-packages/django/template/loader.pyc in render_to_string(template_name, dictionary, context_instance, dirs) 168 t = select_template(template_name, dirs) 169 else: --> 170 t = get_template(template_name, dirs) 171 if not context_instance: 172 return t.render(Context(dictionary)) /home/oliver/.virtualenvs/base/local/lib/python2.7/site-packages/django/template/loader.pyc in get_template(template_name, dirs) 142 handling template inheritance recursively. 143 """ --> 144 template, origin = find_template(template_name, dirs) 145 if not hasattr(template, 'render'): 146 #

I'm trying to figure out if anyone else can reproduce this problem (I already tested it on LinuxMintDebianEdition and Raspbian) or tell me what I'm doing wrong. The "webform.html" is a regular file under " /home/oliver/projects/autodelayv3/templates", obviously. -- You received this message because you are subscribed to the Google Groups "Django users" group.
