我想防止用户在发布日期起24小时后更新该帖子
class Post(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
title= models.CharField(max_length=50)
post = models.TextField(max_length=400)
date = models.DateTimeField(auto_now_add=True)
edit = models.DateTimeField(auto_now=True)
class PostForm(forms.ModelForm):
class Meta:
model = Post
fields = '__all__'
class PostUpdateView(LoginRequiredMixin,SuccessMessageMixin,UpdateView):
model = Post
form_class = PostForm
success_message = "updated successfully"
template_name = 'store/create.html'
success_url = reverse_lazy('lists')
def form_valid(self,form):
return super().form_valid(form)
我想让用户只能在发布日期的24小时之前更新帖子，谢谢
您可以过滤查询集，以便仅查询集仅包含Post最近24小时内撰写的：
from datetime import timedelta
from django.utils.timezone import now
class PostUpdateView(LoginRequiredMixin,SuccessMessageMixin,UpdateView):
model = Post
form_class = PostForm
success_message = "updated successfully"
template_name = 'store/create.html'
success_url = reverse_lazy('lists')
def get_queryset(self, *args, **kwargs):
return super().get_queryset(*args, **kwargs).filter(
date__gte=now() - timedelta(days=1)
)
def form_valid(self,form):
return super().form_valid(form)如果更新时间已“过期”，这将返回HTTP 404响应。
