title: Django template pass array to input field
body: <p>I have a hidden input field in my django template where I'm passing as value an array.</p>
  
  <pre><code>  &lt;form method="post" action="{% url 'flights:flight-selection' %}"&gt;{% csrf_token %}
      &lt;input type="hidden" id="fa_f_ids" name="fa_f_ids" value="{{ value.fa_f_ids }}"&gt;
      &lt;button type="submit" class="btn btn-light"&gt;Select&lt;/button&gt;
    &lt;/form&gt;
  </code></pre>
  
  <p>When I submit this form via post request I want to get the value of <code>fa_f_ids</code> as an array but I am getting a string instead when I'd like to get an array.</p>
  
  <pre><code>request.POST.get("fa_flight_id")
  #=&gt; &lt;QueryDict: {'csrfmiddlewaretoken': ['UoYqbTUlNxTEJW5AUEfgsgsLuG63dUsvX88DkwGLUJfbnwJdvcfsFhi75yie5uMX'], 'fa_f_ids': ["['AMX401-1560750900-schedule-0000', 'AMX19-1560782100-schedule-0001']"]}&gt;
  </code></pre>
