This simple view:
{{{
class Ngopi(TemplateView):
template_name = 'base.html'
def get_context_data(self, **kwargs):
context = super(Ngopi, self).get_context_data(**kwargs)
context.update({
'menu': get_template('menu.html')
})
return context
}}}
with `base.html`:
{{{
<html>
<body>
<h1>Ngeteh</h1>
{% include menu %}
</body>
</html>
}}}
and `menu.html`:
{{{
<ul>
<li>Ngeteh</li>
<li>Ngopi</li>
</ul>
}}}
This situation will raise this exception:
{{{

This is fine with django 1.10, but not master (mine is currently
1.11.dev20170109230310)
a quick workaround is to edit
[https://github.com/django/django/blob/ecb59cc6579402b68ddfd4499bf30edacf5963be/django/template/backends/django.py#L63
django/template/backends/django.py Line 63] to be like this:
{{{
def render(self, context=None, request=None):
if isinstance(context, dict): # <-- my temporary workaround
context = make_context(context, request,
autoescape=self.backend.engine.autoescape)
try:
return self.template.render(context)
except TemplateDoesNotExist as exc:
reraise(exc, self.backend)
}}}
