Django文件上传无报错但失败问题排查及解决

我查阅了大量相关问题、遵循Django官方文档并搜索解决方案，但仍无法在Django应用中实现文件上传。无报错提示，form.cleaned_data能正常显示文件及关联的外键字段，但文件并未上传至media目录，数据库中也未生成对应记录。我无法找出遗漏的配置或代码，恳请大家帮忙。

models.py #

class ReportFile(models.Model):
    report = models.ForeignKey(Report, on_delete=models.CASCADE)
    file = models.FileField(upload_to='files/reports')
    uploaded = models.DateTimeField(auto_now_add=True)
    uploaded_by = models.ForeignKey(User, on_delete=models.CASCADE)
    
    def save(self, *args, **kwargs):        
    
        user = get_current_user()
        if user and not user.pk:
            user = None
        if not self.pk:
            self.creado_por = user
###更新：正如Iain Shelvington指出的，我遗漏了super()调用
        super(ReportFile, self).save(*args, **kwargs)

forms.py #

class FileForm(forms.ModelForm): 
    class Meta:                
        model = ReportFile
        fields = ['file','report']

views.py #

def CreateFile(request):
  if request.method == 'POST':
    form = FileForm(request.POST,request.FILES)
    if form.is_valid():
        form.save()
        
        print(form.cleaned_data)
#输出：HTTP POST /file 200 [0.09, 127.0.0.1:59053] 
#        {'file': <InMemoryUploadedFile: test-image.png (image/png)>, 'report': <Report: 49>}
        return render(request, 'segcom/file_upload.html', {'form': form,})
  else:
    form = FileForm()
    context = {
        'form':form,
    }
return render(request, 'segcom/file_upload.html', context)

settings.py #

# Media Root
MEDIA_ROOT = os.path.join(BASE_DIR, "media")
MEDIA_URL = '/media/'

问题解决 #

最终发现问题根源是在ReportFile的save方法中未调用super()，添加后问题解决。
