Invalid template name in 'extends' tag: ''. Got this from the 'baseX.html'
variable.
The first line in index.html is:
{% extends baseX.html %}
I got this error when trying out a new template package I bought. I thought
it was telling me something was wrong with the name of the base template
being extended, but changing the name numerous times always brings the same
error.
I tried using a functional view instead, but I still got the same error.
Debug Toolbar says:
Templates
>
> index.html
> /home/malikarumi/Projects/cannon/jamf/static/index.html
> ▶ Toggle context
> None
> <unknown source>
>
That's when I figured out that the error was with baseX itself. The
traceback points to line 141 in loader_tags.py, which is the get_parent
function:
def get_parent(self, context):
parent = self.parent_name.resolve(context)
if not parent:
error_msg = "Invalid template name in 'extends' tag: %r." %
parent
if self.parent_name.filters or\
isinstance(self.parent_name.var, Variable):
error_msg += " Got this from the '%s' variable." %\
self.parent_name.token
raise TemplateSyntaxError(error_msg)
if isinstance(parent, Template):
# parent is a django.template.Template
return parent
if isinstance(getattr(parent, 'template', None), Template):
# parent is a django.template.backends.django.Template
return parent.template
return self.find_template(parent, context)
Both baseX and index are in the same folder. Somehow Django has decided my
baseX is not a django.template.django.Template. I don't know what makes a
template qualify as a django.Template, and wasn't able to find anything on
that. baseX is a pre-made template I liked and bought online. The designer
doesn't know anything about Django. As far as I can tell, it is just html,
css, and javascript, like any other template. It is bootstrap, just like
the template I was using before. I have searched around, there's lots of
stuff about templates in general, but I haven't found anything on this
particular issue.
I did come across django-bootstrap3, but I see no reason why that's
required to use bootstrap. I didn't have it with the previous bootstrap
theme I was using and that worked.
Your insights appreciated.
