Question

year_id (2004 etc) is a dropdown box on the template. The users selects a year and this is retrieved as year_id in the view. I need to select publications based on year from a field called grantstartdt which is in the format 2008-01-01. The error is:

int() argument must be a string or a number, not ‘Year’

year_id = request.GET['year_id']  
yr = get_object_or_404(Year, pk=year_id) 
projectyr=Researchproject.objects.exclude(activeyesno = 2).filter(grantstartdt__year=yr)  

Thank you for any assistance!

Answer 1

Try passing year_id instead of yr in that filter() call:

projectyr=Researchproject.objects.exclude(activeyesno = 2).filter(grantstartdt__year=year_id)
