我正在嘗試添加 IF 語句，以便當點贊數(shù)達到 2 時發(fā)送電子郵件。我已經(jīng)編寫了代碼，但它不起作用，我正在嘗試以下代碼，但它不起作用。我的問題是如何添加 if 語句，以便當任何具有 like more the 2 的項目時，都會向電子郵件發(fā)送特定的電子郵件。這是 models.pyclass Post(models.Model): title = models.CharField(max_length=100, unique=True) likes = models.ManyToManyField( User, related_name='liked', blank=True) def __str__(self): return self.title def total_likes(self): return self.likes.count()這是views.pyclass PostDetailView(DetailView): model = Post template_name = "post_detail.html" def get_context_data(self, *args, **kwargs): context = super(PostDetailView, self).get_context_data() post = get_object_or_404(Post, slug=self.kwargs['slug']) comments = Comment.objects.filter( post=post, reply=None).order_by('-id') total_likes = post.total_likes() liked = False if post.likes.filter(id=self.request.user.id).exists(): liked = True if self.request.method == 'POST': comment_form = CommentForm(self.request.POST or None) if comment_form.is_valid(): content = self.request.POST.get('content') reply_id = self.request.POST.get('comment_id') comment_qs = None if reply_id: comment_qs = Comment.objects.get(id=reply_id) comment = Comment.objects.create( post=post, user=self.request.user, content=content, reply=comment_qs) comment.save() return HttpResponseRedirect("post_detail.html") else: comment_form = CommentForm() context["total_likes"] = total_likes context["liked"] = liked context["comments"] = comments context["comment_form"] = comment_form return context def get(self, request, *args, **kwargs): res = super().get(request, *args, **kwargs) self.object.incrementViewCount() return res

如果您希望這種情況在任何地方發(fā)生，我建議向模型save()的方法添加一個覆蓋Post，并在它增加到兩個喜歡時向那里發(fā)送電子郵件。您還可以使用 Django 的send_mail函數(shù)，它是發(fā)送電子郵件的一個很好的包裝器。胖模型、瘦視圖、愚蠢模板是 Django 最佳實踐的口頭禪。也許是這樣的：
from django.core.mail import send_mail
class Post(models.Model):
title = models.CharField(max_length=100, unique=True)
likes = models.ManyToManyField(
User, related_name='liked', blank=True)
def __str__(self):
return self.title
def save(self, *args, **kwargs):
if self.total_likes() == 2:
send_mail(
"my subject",
"my text message",
"myemail@myhost.com",
["myuser@theirhost.com"],
html_message="<h1>My HTML Message</h1>",
)
super().save(*args, **kwargs)
def total_likes(self):
return self.likes.count()
祝你好運！
