Django ModelForm이 필드 오류를 표시하지 않습니다.

Question

템플릿에 필드 오류를 제대로 표시하지 않는 Django ModelForm이 있습니다. 필요한 필드가 여러 개 있으며 사용자에게 오류를 캡처하고 표시하는 올바른 논리라고 생각합니다.

양식을 제출하면, 나는 다음과 같은 오류 얻을 : 여기

class ApplicationCreateView(CreateView): 
    model = Application 
    form_class = ApplicationForm 
    success_url = 'submitted/' 

    def dispatch(self, *args, **kwargs): 
     self.job = get_object_or_404(Job, slug=kwargs['slug']) 
     return super(ApplicationCreateView, self).dispatch(*args, **kwargs) 

    def form_valid(self, form): 
     #Get associated job and save 
     self.object = form.save(commit=False) 
     self.object.job = self.job 
     self.object.save() 

     # Gather cleaned data for email send 
     first_name = form.cleaned_data.get('first_name') 
     last_name = form.cleaned_data.get('last_name') 
     email_address = form.cleaned_data.get('email_address') 
     phone_number = form.cleaned_data.get('phone_number') 
     salary_requirement = form.cleaned_data.get('salary_requirement') 
     description = form.cleaned_data.get('description') 
     portfolio_url = form.cleaned_data.get('portfolio_url') 
     can_relocate = form.cleaned_data.get('can_relocate') 
     start_date = form.cleaned_data.get('start_date') 
     resume = self.object.resume 
     job = self.object.job 

     #Compose message 
     email = EmailMessage() 
     email.body = 'Name: ' + first_name + last_name + '\n' + 'Email: ' + email_address + '\n' + 'Phone number: ' + str(phone_number) + '\n' + 'Salary requirement: ' + str(salary_requirement) + '\n' + 'Description: ' + description + '\n' + 'Portfolio URL: ' + portfolio_url + '\n' + 'Can relocate: ' + str(can_relocate) + '\n' + 'Start date: ' + str(start_date) 
     email.subject = 'A new application has been submitted for %s' % (job) 
     email.from_email = 'noreply@abc.com' 
     email.to = ['jobs@abc.com',] 
     email.bcc = ['abc@abc.com',] 
     email.attach(resume.name, resume.read()) 
     email.send() 
     return HttpResponseRedirect(self.get_success_url()) 

    def get_context_data(self, *args, **kwargs): 
     context_data = super(ApplicationCreateView, self).get_context_data(*args, **kwargs) 
     context_data.update({'job': self.job}) 
     return context_data 

그리고 다음은

     resume = cleaned_data.get('resume') 
     resume_ext = resume.name.lower().split('.')[1]

      raise forms.ValidationError(msg) 
      #self._errors["resume"] = self.error_class([msg])  
     return cleaned_data

Answer 1

내 솔루션 (forms.py에서) 다음과 같이했다 : 그는 아무도없는 사촌 여기

는 예외입니다 질문 (Django ModelForm not showing field errors).

Answer 2

는 말한다 : 청소 데이터

resume = cleaned_data.get('resume') 

어쩌면

resume 없다 "resume 더 속성 name이없는 개체"? 인쇄를 시도하거나 pudb을 입력하십시오.

def clean(self): 
    cleaned_data = super(ApplicationForm, self).clean() 
    if cleaned_data.get('resume'): 
     resume = cleaned_data.get('resume') 
     resume_ext = resume.name.lower().split('.')[1] 
     if not resume_ext in ('pdf', 'doc', 'docx'): 
      del cleaned_data["resume"] 
      msg = u"Your file must be a PDF or DOC file type." 
      self._errors["resume"] = self.error_class([msg])   
     return cleaned_data 
    else: 
     return cleaned_data 

이 원래의 의견에 의해 영감을했다 : 공식적으로

resume_ext = resume.name.lower().split('.')[1]
