title: Django - Invalid block tag: 'csrf_tokan', expected 'endblock'
body: <p>I cannot understand why my django app does not understand template tags.
  I get this error:</p>
  
  <p>Invalid block tag: 'csrf_tokan', expected 'endblock'</p>
  
  <p>urls.py:</p>
  
  <pre><code>urlpatterns = patterns('',
      url(r'^index/', 'myproj.views.index'),
      url(r'^admin/', include(admin.site.urls)),
  )
  </code></pre>
  
  <p>views.py:</p>
  
  <pre><code>@staff_member_required
  def index(request):
      return render(request, 'index.html', locals())
  </code></pre>
  
  <p>index.html:</p>
  
  <pre><code>{% extends "admin/base.html" %}
  {% block content %}
       {% csrf_tokan %}
  {% endblock %}
  </code></pre>
  
  <p>Any ideas?</p>
