Question

Error:

Reverse for ‘charges_report’ with arguments ‘(u’rtcl’, datetime.date(2012, 1, 3), datetime.date(2012, 1, 4), u”)’ and keyword arguments ‘{}’ not found.

in my urls.py

   url(r'^charges_report/(?P<company_name>[\s\w\d-]+)/(?P<start_date>[\s\w\d-]+)         /(?P<close_date>[\s\w\d-]+)/(?P<batch_no>[\s\w\d-]+)/$', 
                                'admin.reports.views.charges_report',
                                name='charges_report'),

and in my form views on POST

When user submits form the error is occurring. I mean on request.POST, Here is the code for form submit

      if request.POST:
        company_form = CompanyForm(request.POST, request=request)

         if company_form.is_valid():
           company_name =  company_form.cleaned_data['company_name']
           start_date = company_form.cleaned_data['start_date']
           close_date = company_form.cleaned_data['close_date']
           batch_no = company_form.cleaned_data['batch_no']


        #if 'immigration_charges' in request.POST:

        return        HttpResponseRedirect(reverse('charges_report',args=[company_name, start_date, close_date, batch_no])) 

in views

  def charges_report(request, company_name, start_date, close_date, batch_no=None,):

Answer 1

Your URL is taking keyword arguments, but you are passing positional arguments in reverse.

Try:

  kwargs = dict()
  kwargs['company_name'] = company_name
  kwargs['start_date'] = start_date
  kwargs['close_date'] = close_date
  kwargs['batch_no'] = batch_no
  return HttpResponse(reverse('charges_report',kwargs=kwargs))

You also need to format your dates to match the regular expression in your URL pattern. Right now you are passing the literal string datetime.date(2012, 1, 3) as the start_date.

Change start_date (and close_date) to something that matches your regular expression, something like this:

kwargs['start_date'] = "{}".format(start_date)
kwargs['close_date'] = "{}".format(close_date)
