title: Why am i getting the TypeError:context must be a dict rather than Context. Django
body: <p>Trying to setup a webpage to list the tags for startups (following along in Django unleashed). The book uses Django 1.8, and Im using 3.0. There are spots where ive seen deprecated functions in the book and was able to find what the updated replacement was, but i cant figure out why django is giving me this error when loading the homepage. Still kinda new at Python and Django. I do have tags created, when executing <code>Tag.objects.all()</code> and one startup has been saved to the database which has its related tag.</p>

  from django.template import Template, Context, loader

      tag_list = Tag.objects.all()
      template = loader.get_template('organizer/tag_list.html')
      context = Context({'tag_list':tag_list})
      output   = template.render(context)
      return HttpResponse(output)
