title: Django ManagementForm data is missing or has been tampered with
body: <p>I keep getting the error:</p>
  
  <pre><code>[u'ManagementForm data is missing or has been tampered with']
  </code></pre>
  
  <p>I can't figure out why either. Here is my view: </p>
  
  <pre><code>   def CreateWorkout(request):
      WorkoutInlineFormSet = inlineformset_factory(workout,exercise)
      if request.method == "POST" : 
          formset = WorkoutInlineFormSet(request.POST)
  
          if formset.is_valid(): 
              formset.save(); 
      else: 
          formset = WorkoutInlineFormSet()
      return render_to_response('submit.html',{'formset': formset},context_instance=RequestContext(request))
  </code></pre>
  
  <p>And here is my template: </p>
  
  <pre><code>&lt;body&gt;
  &lt;form method="POST" action =""&gt;
  {{ formset.management_form }}
  &lt;table&gt;
   {% for form in formset.forms %}
              {{ form }}
          {% endfor %}
  
          &lt;/table&gt;
  &lt;/form&gt; 
  &lt;/body&gt;
  </code></pre>
  
  <p>I've read that you have to include the <code>formset.management_form</code>, and I have. I thought that would be an easy fix, but I haven't been able to figure out the problem.</p>
