Question

我正在使用Django制作商店类型的网站，目前正在制定审核和评级系统。我的评论＆＃39;应用程序包含一个名为＆＃39; Review＆＃39;以及从产品说明模板添加评论的视图。模特：

class Review(models.Model):
    product = models.ForeignKey(Product, on_delete=models.CASCADE)
    author = models.ForeignKey('auth.User', on_delete=models.CASCADE)
    title = models.CharField(max_length=100)
    content = models.TextField()
    rating = models.IntegerField(blank=True, null=True)
    created_date = models.DateTimeField(auto_now_add=True)

我遇到的问题是视图没有通过product_id字段，导致NOT NULL约束失败错误。该观点如下：

@login_required
def add_review(request):

    if request.user:
        if request.method == "POST":
            review_form = ReviewForm(request.POST)
            if review_form.is_valid():
                review = review_form.save(commit=False)
                review.author = request.user
                review_form.save()

                messages.success(request, "Review posted successfully!")
                return redirect(reverse(get_reviews))
        else:
            review_form = ReviewForm()
    else:
        messages.error(request, "You must be a member to post reviews.")
        return redirect(reverse(get_reviews))

    args = {'review_form': review_form}
    return render(request, "add_review.html", args)

然而，当我尝试通过使用相同的方法来传递作者（我知道我在其他地方使用过该代码的工作）来纠正它时，我得到一个WSGIRequest错误，声明＆＃34;对象有没有属性＆＃39;产品＆＃39; ＆＃34 ;.添加的行如下所示：

            ...
            if review_form.is_valid():
                review = review_form.save(commit=False)
                review.product = request.product
                review.author = request.user
                review_form.save()
                ...

可能很明显，但我的Django知识有点受限，因为我还在学习它。任何人都可以指出我正确的方向吗？

提前致谢。

编辑：我被要求分享urls.py，所以这里是：

from django.conf.urls import url
from .views import review_content, add_review, edit_review, delete_review

urlpatterns = [
    url(r'^(?P<pk>\d+)/$', review_content, name='review-content'),
    url(r'^add-review/$', add_review, name='add-review'),
    url(r'^(?P<pk>\d+)/edit/$', edit_review, name='edit-review'),
    url(r'^(?P<pk>\d+)/delete-review/$', delete_review, name='delete- 
                                                              review'),
]

Django - NOT NULL约束失败，WSGIRequest错误
