I'm using Django, using a Postgres DB, and I wonder: say I have a function like this: def yay_func(obj): log('yay') obj.is_yay = True obj.save() If I wrap this function in a transaction, will I cause any strain on my db?

Get ID in Django
I have a website made in Django, where people shall be able to post questions and answer them -just like a copy of Stack Overflow. When the user visits http://localhost/?post=Example it filters the database for posts with the name example. Later on I will do so there can only be exactly one post with the same name. Currently it just renders the post/question in the HTML document using {{post.author}} for instance. posts = Post.objects.filter(title=post) context = {'posts':posts}#, "answers":answers} return render(request, 'store/post.html', context) On Stack Overflow it is possible to answer a question. There can be multiple ones. So in my code I did this by making a foreignkey in a model called Answer that is linking the answer to a post. In the HTML document I made a for loop -just like I did for the post/question and looped through all answers and displayed them under the question. class Customer(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, null=True, blank = True) name = models.CharField(max_length=200, null=True) email = models.EmailField(max_length=200, null=True) about = models.CharField(max_length=100, null=True, help_text="Use this field for notes about the customer.") image = models.ImageField(null=True, blank=True) @property def imageURL(self): try: url = self.image.url except: url = 'placeholder.png' return url def __str__(self): return self.name class …
