Question

Up until a couple days ago I have been using the following query succesfully. The following query has always returned the data it was supposed to return:

try:
  totals = MyObject.objects.get(date=report_date)
except MyObject.DoesNotExist:
  return HttpResponse('Could not find totals from %s' % (report_date))

A couple days ago this query began returning an empty QuerySet, even though data Does exist for the day I am requesting.

I am getting the date from report_date = date.today().strftime('%Y-%m-%d')
or from a form

if request.method == 'POST':
  form = DateForm(request.POST)
  if form.is_valid:
    report_date = request.POST['date']

The Model is simple datefield()

class MyObject(models.Model):
  """Total numbers for a specific day"""
  date = models.DateField()
  ... remaining fields ...

I have verified through the shell that there is in fact data for todays date in TotalTransactions. I have been using this code for months with no problem. I made a work around yesterday by querying
totals = MyObject.objects.get(date__gte=report_date, date__lte=report_date)
but this morning it no longer worked!! This morning I then tried the original query of date=report_date and that worked!

So my question is: Has anyone had this problem before?? Can anyone see something in my code that i am missing? Any suggestions on more workarounds? I appreciate your time.

Answer 1

why converting to the string? you do not have a control on how date is converted, eg. locale issues.

switch to date objects and set in views only:

report_date = date.today()

and get data from the form’s cleaned_data dict:

report_date = form.cleaned_data['date']
