Why is my Django template not displaying?

[Dave N]

Assuming my model contains data, I have myapp/views.py:

from django.template import RequestContext
from django.shortcuts import render
from .models import History
import datetime

def live_view(request):
    context = RequestContext(request)
    plays_list = History.objects.filter(date=datetime.date(2016,04,22))
    context_list = {'plays':plays_list}
    return render(request,'live.html',context_list)

myapp/templates/live.html:

{% extends 'base.html' %}
{% block content %}
{% for key, value in context_list.items %}
    {{ value }}
{% endfor %}
{% endblock %}
myapp/urls.py:
from myapp.views import live_view
urlpatterns = [url(r'^live/$', live_view, name="live"),]

The output is a page that renders only the base.html template, with no content in the body. What's wrong with my view function or template rendering? Should I be inheriting from TemplateView?

You probably want {% for key, value in plays.items %} since there probably isn't a context variable called {{ context_list }}.

Install the Django-debug-toolbar. It'll tell you everything that's available in the template context and provide what templates were actually rendered on every page load, along with other cool stuff you didn't even know you needed to know.

That absolutely did it James - I thought I was accessing the instance, but what I needed was to access the template context contents of the instance. Also, great tip with the django debug toolbar - I've had it installed, but didn't know how much it actually shows!

Use  plays as a list in form.

You are passing context_list as context object so all variable inside context_list are available in template but not context_list.

Other option is
return render(request,'live.html',
{"context_list": context_list})
