title: Django - How to append to a Django queryset (values)
body: <p>how do I append a dictionary into a Django queryset? I did .values on the queryset already, but it still classifies as a queryset and when I try to use .append on it, this error came up </p>
  
  <pre><code>AttributeError: 'QuerySet' object has no attribute 'append'
  </code></pre>
  
  <p>Here is my code: (start and end are variables passed in to denote the start month and end month of the selected range)</p>
  
  <pre><code>qs = CustomerInformation.objects.filter(salesDepartment__in=[d]).filter(created_date__range=(start,end))
  qs = qs.annotate(date=TruncMonth('created_date')).values('date').annotate(lead_count=Count('status',filter=Q(status="lead"))).annotate(client_count=Count('status',filter=Q(status="client")))
  qs = qs.values('date', 'client_count', 'lead_count')
  </code></pre>
  
  <p>All I want to do is to add the missing dates to the queryset, like for example if my queryset has date: April 2020 and June 2020, but is missing May 2020 due to CustomerInformation not having any instances with created_date in range of May 2020, hence I want to be able to insert a dictionary with date: May 2020 and lead_count and client_count 0 so that my data visualisation would work properly</p>
  
  <p>Thanks all, all help is appreciated!</p>
