我想限制上傳文件上的用戶數量。例如: 每天,用戶被限制爲1個圖像文件。Django上傳限制
查看
class Upload(views.LoginRequiredMixin, generic.CreateView):
model = Posts
form_class = UploadForm
template_name = 'icerik_yukle.html'
def form_valid(self, form):
self.object = form.save(commit=False)
self.object.author= self.request.user
self.object.save()
return super(Upload, self).form_valid(form)
模式
class Gonderi(models.Model):
author= models.ForeignKey(User, related_name="gonderi")
slug = models.SlugField(unique=True, max_length=10, default=id_olustur)
image = models.FileField(upload_to=yukleme_adresi, blank=True)
subject= models.CharField(max_length=50, blank=True)
descrip = models.TextField(max_length=250, blank=True)
category= models.ForeignKey(Kategori, verbose_name="Kategori")
tags = TaggableManager()
created= models.DateTimeField(auto_now_add=True)
updated= models.DateTimeField(auto_now=True)
is_public = models.BooleanField(verbose_name='Göster', default=True)
嗨,謝謝你的回答。我嘗試了代碼,但沒有工作。上傳可以沒有限制地完成。 –
@SaadettinYasirAKEL你是否例外? – levi
我嘗試過這種方式。我爲新手感到抱歉。 'def form_valid(self,form): sorgu = Gonderi.objects.filter(olusturma_zamani = datetime.now()。date(), sanatci = self.request.user) instance = sorgu [0] if sorgu.count ()> 0 else None if instance and instance.resim: raise Exception(「Günlüklimitiniz doldu。」) self.object = form.save(commit = False) self.object.sanatci = self.request.user self.object.save()' –
