Question

我正在尝试将用户评论存储到单独的数据库表中。例如有两个图像（例如image1和image2），如果用户对image1进行评论，我想将用户评论存储到image1表。如果有人对image2进行注释，则数据存储到image2表中。该怎么做，请帮帮我。

view.py

def review(request):
    address = request.session['address']
    image1 = Offers.objects.filter(address=address)
    image2 = Ads.objects.filter(address=address)
    if 'username' in request.session:
        if request.method == 'POST':
            form = Comments(request.POST)
            if form.is_valid():
                review = request.POST.get('review')
                id = request.POST.get('id_off')
                dt = datetime.now().strftime('%Y-%m-%d %H:%M:%S')
                result1 = Image1(review=review, id= id, date_time= dt)
                result2 = Image2(review=review, id= id, date_time= dt)
                result1.save()
                result2.save()
                return render(request, 'index.html', {'image1': image1, 'image2': image2})
            return redirect('/review/')
        return redirect('/review/')
    return redirect('/review/')

index.html

{% for item in image1 %}
              <div class="col-md-4">
                  <div class="divi" style="height: 910px">

        </form>
                </div>
              </div>
        {% endfor %}

urlpatterns = [
    path('review/', views.review, name="review"),

Answer 1

假设您有一个Image模型

class Image(models.Model):
    file=models.ImageField()

和一个Comment模型

class Comment(models.Model):
    comment=models.CharField(max_length=150)

您可以使用Foreignkey定义Image对象和Comment之间的关系

class Comment(models.Model):
    image = models.ForeignKey(Image, on_delete=models.CASCASE)
    comment=models.CharField(max_length=150)

因此，每个图像对象可以有多个注释
