如何让用户在Django中给自己打分？

# models.py
from django.db import models
from django.contrib.auth.models import User

class Rating(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    score = models.IntegerField()

# forms.py
from django import forms

class RatingForm(forms.Form):
    score = forms.ChoiceField(choices=[(1, '1'), (2, '2'), (3, '3'), (4, '4'), (5, '5')])

# views.py
from django.shortcuts import render, redirect
from .models import Rating
from .forms import RatingForm

def rate(request):
    if not request.user.is_authenticated:
        return redirect('login')  # 未登录则跳转到登录页面

    if request.method == 'POST':
        form = RatingForm(request.POST)
        if form.is_valid():
            score = form.cleaned_data['score']
            Rating.objects.create(user=request.user, score=score)
            return redirect('rating_result')  # 评分成功后跳转到评分结果页面
    else:
        form = RatingForm()

    return render(request, 'rate.html', {'form': form})

def rating_result(request):
    average_score = Rating.objects.filter().aggregate(models.Avg('score'))['score__avg']
    return render(request, 'rating_result.html', {'average_score': average_score})
