Hi django experts, just want to know your opinion on how to validate the user input (example: the user input field should be integer, but the user accidentally inputs any character), here is my code:
FYI; the numberofapples field is IntegerField here is my sample code: def apples_edit(request): if request.POST['id']: id = request.POST['id'] numberofapples = request.POST['numberofapples'] conn = psycopg2.connect("dbname=my_db user=user password=pass host=localhost") cur = conn.cursor() try: if isDigit(playerid): pass else: template_name = 'err_template.html' t = loader.get_template(template_name) c = RequestContext(request, {"err_msg":"number of apples should be integer, Please correct your input"}) return HttpResponse(t.render(c)) except ValueError: template_name = 'err_template.html' t = loader.get_template(template_name) c = RequestContext(request, {"err_msg":"number of apples should be integer, Please correct your input"}) return HttpResponse(t.render(c)) sql = """ UPDATE my_db SET "numberofapples"='%s' where "id"='%s' """ % (numberofapples,id) cur.execute(sql) conn.commit() conn.close() ---------------------- My problem is that, the error template does not appear after I type in any character for numberofapples field. What would be the correct code for this? Thanks. -- You received this message because you are subscribed to the Google Groups "Django users" group.
