【问题描述】：
这是我在 Django 中的第一个项目。我正在尝试将评分保存在 Django 数据库中，但是当我单击单选按钮时，该值不会存储在数据库中。我已经尝试过以前上传的 Stack Overflow 的解决方案，但没有一个能帮助我解决我的问题。我最初在 forms.py 中使用 RadioSelect 但仍然遇到同样的问题。
代码如下：
Model.py
class Product(models.Model):
title = models.CharField(max_length=120)
brand = models.CharField(max_length=120,default="None")
model = models.CharField(max_length=120,default="None")
slug = models.SlugField(blank=True, unique=True)
category = models.CharField(max_length=120 , default="Phone")
price = models.DecimalField(decimal_places=2, max_digits=20, default=39.99)
class Rating(models.Model):
product=models.ForeignKey(Product,default=None, on_delete=models.PROTECT)
user=models.ForeignKey(User,default=None, on_delete=models.PROTECT)
rating = models.CharField(max_length=120)
Views.py
def add_rating(request,id):
product = get_object_or_404(Product, pk=id)
pro = Product.objects.get(id=id)
if request.method == "POST":
form = RatingForm(request.POST)
if form.is_valid():
product = form.cleaned_data['product']
user = form.cleaned_data['user']
rating = form.cleaned_data['rating']
product = request.POST.get('product', ''),
user = request.POST.get('user', ''),
rating = request.POST.get('rating', ''),
obj = Rating(product=product, user=user, rating=rating)
obj.save()
context = {'obj': obj}
return render(request, 'product/detail.html',context)
else:
form=RatingForm()
return HttpResponse('Please rate the product')
Forms.py
from django import forms
from .models import Rating
class RatingForm(forms.ModelForm):
class Meta:
model = Rating
fields = ('product', 'user','rating')
template.py
<form method="POST" action="{% url 'add_rating' product.id %}">{% csrf_token %}
<ul class="rate-area" style="display:inline;position:absolute">
<input type="radio" id="5-star" name="rating" value="5" /><label for="5- star" title="Amazing">5 stars</label>
<input type="radio" id="4-star" name="rating" value="4" /><label for="4-star" title="Good">4 stars</label>
<input type="radio" id="3-star" name="rating" value="3" /><label for="3-star" title="Average">3 stars</label>
<input type="radio" id="2-star" name="rating" value="2" /><label for="2-star" title="Not Good">2 stars</label>
<input type="radio" id="1-star" name="rating" value="1" /><label for="1-star" title="Bad">1 star</label>
<button type="submit" value="Rate">Rate</button>
</ul>
</form>
