Noobie needs help debugging simple python/django code. Why won't this view work?

I am trying to complete the simple exercise near the top of the page here: http://www.djangobook.com/en/2.0/chapter07/. When the user goes to mysite.com/meta/ I want to display a simple html table on the page showing the HTTPRequest meta data.

In my urls.py file I have:

from django.conf.urls.defaults import patterns, include, url
from mysite.views import display_request_meta_data

urlpatterns = patterns('',
    url(r'^meta/$', display_request_meta_data),
)

In my views.py file I have:

from django.template.loader import get_template
from django.template import Context
from django.http import HttpResponse
import logging

logger = logging.getLogger(__name__)

def display_request_meta_data(request):
    meta_data = request.META.items()
    meta_data.sort()
    for x in meta_data
        # print x  # wasn't working, so I tried using a logger instead.
        logger.error(x)
    t = get_template('http_meta_data_table.html')
    html = t.render(Context(*meta_data_dict))
    return HttpResponse(html)

In my templates directory I have a file called http_meta_data_table.html which contains the following:

<html>
<head>
    <title>HTTP Meta Data</title>
</head>
<body>
    <table>
        {% for key, value in meta_data_dict %}
            <tr><td>{{key}}</td><td>{{value}}</td></tr>
        {% endfor %}
    </table>
</body>
</html>

What about:

def display_request_meta_data(request):
    meta_data = request.META.items()
    meta_data.sort()
    for x in meta_data: # you were missing a semi column
        # print x  # wasn't working, so I tried using a logger instead.
        logger.error(x)
    t = get_template('http_meta_data_table.html')
    html = t.render(Context({'meta_data': meta_data})) # the dict doesn't exitst
    return HttpResponse(html)

In html, the dict doesn't exist either:

<html>
<head>
    <title>HTTP Meta Data</title>
</head>
<body>
    <table>
        {% for key, value in meta_data %}
            <tr><td>{{key}}</td><td>{{value}}</td></tr>
        {% endfor %}
    </table>
</body>

</html>

This has really nothing to do with django, these are very basic error. Learning programming while using a framework is a bad idea IMO. You should learn the basics before, or your learnin curve is going to look like a straigth wall.

Django is an easy framework to learn, but it assumes you know Python.

meta_data_dict is undefined. You probably was to pass meta_data to t.render
