Specifically you are not using them to validate the input, and your ad-hoc checking of len(request.POST) to see if you have input is likely not doing what you think. Even if the "user_id" field of your form is left blank, it will be present in request.POST with a value of an empty string. Your routine would be much cleaner if you take advantage of the built-in validation support of Django forms.
The DataError "invalid input syntax for integer" is likely coming from the database. Note when you call gen_pdf (which returns an HttpResponse) you do nothing with the return value and just fall through to the subsequent code. You set deal_avail to true because it's a post and len(request.POST) >= 0 (request_id is there, it's an empty string). When you call: deals = Deals.my_manager.get_open_deals(requested_id) with requested_id set to the empty string the database complains that an empty string is not a valid integer.
