Even though the question was asked quite a while back, I was searching for the same kinda feature.
I believe I found the answer to the initial question and the follow up question to JcKelly's post -> 'filter as an actual view' (in which I assume filter means render).
I found this snippet (of a custom templatetag, see post JcKelley for info on custom templatetag) on the web:
https://djangosnippets.org/snippets/1568/ It was outdated for me. Thus I followed it's approach and came up with:
from django.template import Library, Node, Variable, TemplateSyntaxError
from django.conf import settings
from django.urls import reverse, resolve, NoReverseMatch
register = Library()
class ViewNode(Node):
def __init__(self, url_or_view, args, kwargs):
self.url_or_view = url_or_view
self.args = args
self.kwargs = kwargs
def render(self, context):
if 'request' not in context:
raise TemplateSyntaxError("No request has been made.")
url_or_view = Variable(self.url_or_view).resolve(context)
try:
view, args, kwargs = resolve(reverse(url_or_view))
except NoReverseMatch:
view, args, kwargs = resolve(url_or_view)
try:
if callable(view):
self.args += args
self.kwargs.update(**kwargs)
return (view(context['request'], *self.args, **self.kwargs)
.rendered_content)
raise "%r is not callable" % view
except:
if settings.DEBUG:
raise
return None
@register.tag(name='view')
def do_view(parser, token):
args, kwargs, tokens = [], {}, token.split_contents()
if len(tokens) < 2:
raise TemplateSyntaxError(
f"{token.contents.split()[0]} tag requires one or more arguments")
for t in tokens[2:]:
kw = t.find("=")
args.append(t) if kw == -1 else kwargs.update({str(t[:kw]): t[kw+1:]})
return ViewNode(tokens[1], args, kwargs)
Your Template-file.html -> example of usage
Using a view's path name, (see https://docs.djangoproject.com/en/2.2/topics/http/urls/#naming-url-patterns for info on path names):
{% view "mymodule:inner" %}
{% view "mymodule:inner" "value" %}
{% view "mymodule:inner" keyword="value" %}
{% view "mymodule:inner" arg_expr %}
{% view "mymodule:inner" keyword=arg_expr %}
Using a URL (or something that evaluates to a URL):
{% view "/inner" %}
{% view url_expr %}
Hope it may help someone!
