ModelForm 未传递所有参数

Question

经过一些 @kreigar 的大力帮助 我能够开始使用 django 的 ModelForm 而不是 form.Forms。现在唯一的问题是我没有传递两个主键来关联我的评论表单:-(。

目前我的视图如下所示：

 #views.py

 @login_required
 def wine_review_page(request, wine_id):
   wine = get_object_or_404(Wine, pk=wine_id)
   review = None
   if Review.objects.filter(user=request.user, wine=wine).exists():
      review = Review.objects.get(user=request.user, wine=wine)

   if request.method == 'POST':
     form = WineReviewForm(request.POST, instance=review)
     if form.is_valid():
        form.save()   
        return HttpResponseRedirect('/detail/%s/' % wine_id )
   else:
     form = WineReviewForm(instance=review)

   variables = RequestContext(request, {'form': form, 'wine': wine })
   return render_to_response('wine_review_page.html', variables)`

而我的模型表单如下所示：

 #models.py

class WineReviewForm(ModelForm):
    class Meta:
        model = Review
        widgets = {
            'wine': HiddenInput(),
            'user': HiddenInput(),
            'like_dislike': HiddenInput(),
            'fave': HiddenInput(),
            'sweet_dry': HiddenInput(),
            'crisp_buttery: HiddenInput(),
            'fruity_earthy': HiddenInput(),
            'smooth_spicy': HiddenInput(),
            'light_robust': HiddenInput(),
            'label_rating': HiddenInput()
            }

Wine_review_form：

 <form method="post" action="/review/{{ wine.id }}/">
 {% csrf_token %}
 {{form.as_p}}


<div id="form_div" data-role="fieldcontain">
<script>

在检查我的帖子请求时，我唯一没有传递的是：wine_id 和 user_id。这确实令人困惑。

我错过了一些简单的事情吗？

我查看了 文档 和示例，但到目前为止没有运气。

Answer 1

实际上看起来您不需要 wine_id 和 user_id （除非您想允许用户为其他用户发表评论，或者即时切换他们正在评论的葡萄酒）。

这应该对您有用：

@login_required
def wine_review_page(request, wine_id):
    wine = get_object_or_404(Wine, pk=wine_id)

    if Review.objects.filter(user=request.user, wine=wine).exists():
        review = Review.objects.get(user=request.user, wine=wine)
    else:
        review = Review(user=request.user, wine=wine) #this added

    if request.method == 'POST':
       form = WineReviewForm(request.POST, instance=review)
       if form.is_valid():
           form.save()   
           return HttpResponseRedirect('/detail/%s/' % wine_id )
    else:
       form = WineReviewForm(instance=review)

    variables = RequestContext(request, {'form': form, 'wine': wine })
    return render_to_response('wine_review_page.html', variables)

如果您确实希望允许用户修改这些字段中的任何一个，请编辑您的问题以显示您的模板或用户如何提交数据，因为您的所有字段都使用hiddenInput小部件，很难判断数据如何进入请求。POST
