title: how to activate DJANGO.CORE.CONTEXT_PROCESSORS.REQUEST
body: <p>I read this</p>
  
  <blockquote>
    <p><code>DJANGO.CORE.CONTEXT_PROCESSORS.REQUEST</code></p>
    
    <p>If <code>TEMPLATE_CONTEXT_PROCESSORS</code> contains this processor, every
    RequestContext will contain a variable request, which is the current
    HttpRequest. Note that this processor is not enabled by default;
    you'll have to activate it.</p>
  </blockquote>
  
  <p>from <a href="http://docs.djangoproject.com/en/dev/ref/templates/api/" rel="nofollow noreferrer">this page</a></p>
  
  <p>But it seems there is no information how to activate this processor.</p>
  
  <p>Here is my original question </p>
  
  <p><a href="https://stackoverflow.com/questions/2160261/access-request-in-django-custom-template-tags">Access request in django custom template tags</a></p>
  
  <p>After i followed the answer</p>
  
  <p>i still got errors</p>
  
  <pre><code>TemplateSyntaxError at / Caught an exception while rendering: 'request' Original Traceback (most recent call last):

  <p>the code causing problem is </p>
  
  <p><strong>request = context['request']</strong>   in </p>
  
  <pre><code>from django import template
  
  register = template.Library()
  
  
  @register.inclusion_tag('userinfo.html',takes_context = True)
