    text
    copied!<p>I am using django 1.4 and trying to convert the code described at the end of <a href="http://dashdrum.com/blog/2010/03/full-url-in-django/" rel="nofollow">this article</a> into a customtag. This means I need access to the is_secure and site_name values from the request. Here is my CONTEXT_PROCESSORS in settings.py:</p> <pre><code>CONTEXT_PROCESSORS = ( 'django.core.context_processors.request', 'django.contrib.auth.context_processors.auth', ) </code></pre> <p>Here is my template tag code:</p> <pre><code>from django import template register = template.Library() @register.simple_tag(takes_context=True) def full_static_url(context, url): request = context['request'] scheme = 'http' if request.is_secure: scheme += 's' return scheme + '://' + request.site_name + context['STATIC_URL'] + url </code></pre> <p>In my view code I am using the new render shortcut like so:</p> <pre><code>return render(request, 'myapp/mytemplate.html', {'foo':bar}) </code></pre> <p>And I am calling it like this in the template:</p> <pre><code>{% full_static_url "images/logo.gif" %} </code></pre> <p>The problem is, when it gets to the line <strong>request = context['request']</strong> it throws a KeyError because 'request' is not in context.</p> <p>What am I doing wrong here?</p> <p>Full traceback is:</p> <pre><code>File "C:\Python27\lib\site-packages\django\core\handlers\base.py" in get_response 111. response = callback(request, *callback_args, **callback_kwargs) File "C:\Projects\blah\blah\myapp\views\myview.py" in manifestcosts 44. return render(request, 'myapp/mytemplate.html', {'foo':bar}) File "C:\Python27\lib\site-packages\django\shortcuts\__init__.py" in render 44. return HttpResponse(loader.render_to_string(*args, **kwargs), File "C:\Python27\lib\site-packages\django\template\loader.py" in render_to_string 176. return t.render(context_instance) File "C:\Python27\lib\site-packages\django\template\base.py" in render 140. return self._render(context) File "C:\Python27\lib\site-packages\django\template\base.py" in _render 134. return self.nodelist.render(context) File "C:\Python27\lib\site-packages\django\template\base.py" in render 823. bit = self.render_node(node, context) File "C:\Python27\lib\site-packages\django\template\debug.py" in render_node 74. return node.render(context) File "C:\Python27\lib\site-packages\django\template\defaulttags.py" in render 185. nodelist.append(node.render(context)) File "C:\Python27\lib\site-packages\django\template\base.py" in render 1107. return func(*resolved_args, **resolved_kwargs) File "C:\Projects\blah\blah\myapp\templatetags\mytags.py" in full_static_url 25. request = context['request'] #TODO this fails with an KeyError, don't know why File "C:\Python27\lib\site-packages\django\template\context.py" in __getitem__ 54. raise KeyError(key) Exception Type: KeyError at /myapp/myurl/110505081136179000/ Exception Value: 'request' </code></pre>
