Select a valid choice. 2 is not one of the available choices – Html

Learning Django and have some problem. I created a function to change user review, but when I click on the save button, I have error: "Select a valid choice. 2 is not one of the available choices.".

models.py

class ProductReview(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    product = models.ForeignKey(Product, on_delete=models.CASCADE)
    review_text = models.TextField()
    review_rating = models.CharField(choices=RATING, max_length=150)

    def get_review_rating(self):
        return self.review_rating

class UserAddressBook(models.Model):
    user = models.ForeignKey(User,on_delete=models.CASCADE)
    mobile = models.CharField(max_length=12, null=True)
    address = models.TextField()
    status = models.BooleanField(default=False)

views.py

    def my_reviews(request):
        reviews = ProductReview.objects.filter(user=request.user).order_by('-id')
        return render(request, 'user/reviews.html', {'reviews':reviews})
    
    def save_review(request, pid):
        product = Product.objects.get(pk=pid)
        user = request.user
        review = ProductReview.objects.create(
            user=user,
            product=product,
            review_text=request.POST['review_text'],
            review_rating=request.POST['review_rating'],
        )
        data = {

            'review_rating': request.POST['review_rating'],

        avg_reviews = ProductReview.objects.filter(product=product).aggregate(avg_rating=Avg('review_rating'))

I followed the creation algorithm from the tutorial to update the address book. Changing the address book works. Maybe I’m missing something, but I’ve been reviewing the code for several hours now and can’t find an error.
