두보기 -> ValueError를 : 기본 10

Question

는 int()에 대한 유효하지 않은 문자 이것은 내가 양식보기 및 단일 웹 페이지로 데이터베이스 액세스보기를 넣었습니다 Two views in one page

의 연속입니다. 현재 양식보기가 작동하지 않고 위의 오류를 제공합니다.

오류를주는 라인이 updated_event = event.signed_up.remove(request.POST.get('for_removal'))

이이이 for_removal 필드

signed_up  = models.ManyToManyField(User, related_name='signed_up', verbose_name='Already signed-up', blank=True, null=True) 

그리고 이것이를 참조하고 내 models.py 내 views.py

def ShowSpecificEvent(request, eventslug): 
event = Event.objects.get(slug=eventslug) 
form = RemovalForm(request.POST or None) 
context = {'event': event, 'form': form,} 
if request.method == 'POST': 
    if form.is_valid(): 
     updated_event = event.signed_up.remove(request.POST.get('for_removal')) 
     updated_event.save() 
     return HttpResponseRedirect('base_user_removed.html') 
    else: 
     return render_to_response('base_specific_event.html', context, context_instance=RequestContext(request)) 
return render_to_response('base_specific_event.html', context, context_instance=RequestContext(request)) 

입니다 입력을 제공하는 내 forms.py

class RemovalForm(forms.Form): 
for_removal = forms.CharField(label='Username of attendee to be removed') 

def clean_removalform(self): 
    for_removal = self.cleaned_data['for_removal']   

미리 감사드립니다. (PS 나는 그것이 this 또는 that

역 추적에 관련이 있다는 느낌했습니다 :

내가 좀 수동으로 데이터베이스에 사용자가 액세스하고 제거에 넣어 방식을 해킹 한을() 메소드 :

def ShowSpecificEvent(request, eventslug): 
event = Event.objects.get(slug=eventslug) 
form = RemovalForm(request.POST or None) 
context = {'event': event, 'form': form,} 
if request.method == 'POST': 
    if form.is_valid(): 
     x = event.signed_up.get(username = form.cleaned_data['for_removal'],) 
     event.signed_up.remove(x) 
     event.save() 
     return render_to_response('base_specific_event.html', context, context_instance=RequestContext(request)) 
    else: 
     return render_to_response('base_specific_event.html', context, context_instance=RequestContext(request)) 
return render_to_response('base_specific_event.html', context, context_instance=RequestContext(request))
