如何在我的 django 表单中保存或存储用户上传的文档？

Question

我有一个 django 表单，它接受用户的投诉并将它们保存在管理面板中。一切似乎都很完美。该表单接受数据并将它们全部存储在管理面板中，上传文件数据除外。该表单确实接受了来自用户的文件并且似乎提交了它但是当其他数据被完美存储时，该文件没有被存储。我如何上传和保存文件？

models.py:

class Complaint(models.Model):
   user = models.ForeignKey(User, on_delete= models.CASCADE, null = True, blank=True)
   reportnumber = models.CharField(max_length=500 ,null = True, blank= False)
   eventdate = models.DateField(null=True, blank=False)
   event_type = models.CharField(max_length=300, null=True, blank=True)
   device_problem = models.CharField(max_length=300, null=True, blank=True)
   manufacturer = models.CharField(max_length=300, null=True, blank=True)
   product_code = models.CharField(max_length=300, null=True, blank=True)
   brand_name = models.CharField(max_length = 300, null=True, blank=True)
   exemption = models.CharField(max_length=300, null=True, blank=True)
   patient_problem = models.CharField(max_length=500, null=True, blank=True)
   event_text = models.TextField(null=True, blank= True)
   document = models.FileField(upload_to='static/documents', blank=True, null=True)

   def __str__(self):
       return self.reportnumber

views.py:

def NewComplaint(request):
   user = request.user
   if request.method == 'POST':
       form = ComplaintForm(request.POST)
       print(form)
       if form.is_valid():
           print("hello")
           cmp_obj = form.save(commit=False)
           cmp_obj.user = user
           cmp_obj.save()
       submitbutton= request.POST.get('submit')

       if submitbutton:
           messages.success(request, 'Submitted!')
       context = {'form': form}
       return render(request, 'new.html', context)
   else:
       form = ComplaintForm()
       context = {'form': form}
       return render(request,'new.html',context)

forms.py:

class DateInput(forms.DateInput):
   input_type = 'date'

class ComplaintForm(ModelForm):
   class Meta:
       model = Complaint
       fields = '__all__'
       widgets = {

           'patient_problem': forms.TextInput(attrs={'placeholder': 'Enter Patient Problem'}),
       }
    
   def clean(self):
       cleaned_data = super(ComplaintForm, self).clean()
       reportnumber = cleaned_data.get('reportnumber')
       event_text = cleaned_data.get('event_text')
       if not reportnumber and not event_text:
           raise forms.ValidationError('You have to write something!')
       return cleaned_data

如何保存文档文件字段中的表单？我已经给出了应该上传文件的路径，但文件也没有上传到那里

Answer 1

如果你还需要子目录，你应该提到路径。设置媒体URL。确保它工作正常
然后将 request.FILES 作为参数传递：

form = ComplaintForm(request.POST, request.FILES)
