ModelForm没有通过所有参数

Question

在@kreigar的great help之后，我能够开始使用django的ModelForm而不是form.Forms。现在唯一的问题是，我没有通过两个主键到我的评审表:-(关联

目前我的观点看起来像这样：

#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)` 

和我的模型形式是这样的：

​​

Wine_review_form：

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


<div id="form_div" data-role="fieldcontain"> 
<script> 
$('#form_div > input').hide(); 
</script> 

{% if wine.wine_kind == 'whites' %} 
<div class="slider_labels"> 
    <span id="sweet_text"class="left_slider_text">Sweet</span> 
    <span id="dry_text"class="right_slider_text">Dry</span>

<input type="range" name="sweet_dry" id="sweet_dry_slider" value="50" min="0" max="100" onchange="sweetDryValue(this.value)" /> 

<div class="slider_labels">

<input type="range" name="smooth_spicy" id="smooth_spicy_slider" value="50" min="0" max="100" onchange="smoothSpicyValue(this.value)" /> 

{% endif %} 

<div class="slider_labels"> 
    <span id="light_text"class="left_slider_text">Light</span> 
    <span id="robust_text" class="right_slider_text">Robust</span>

</div> 
<input type="range" name="label_rating" id="label_rating_slider" value="50" min="0" max="100" onchange="labelRatingValue(this.value)" /> 

<br> 
<br> 
<div class="ui-grid-b"> 
    <div class="ui-block-a"> 
     <input type="radio" name="like_dislike" id="like" value="like" /> 
    <label for="like">like</label> 
    </div> 
    <div class="ui-block-b"> 
     <input type="radio" name="like_dislike" id="dislike" value="dislike" /> 
    <label for="dislike">dislike</label> 
    </div> 
    <div class="ui-block-c"> 
     <input type="checkbox" name="fave" id="checkbox-1" class="custom" /> 
     <label for="checkbox-1">fave</label> 
    </div> 

    </div>   
</fieldset> 
</div> 

<input type="submit" value="Judged!" rel="external"/> 

当检查我的帖子请求时，我没有传递的唯一信息是：wine_id和user_id。这真是令人困惑。

我错过了那么简单吗？

我看了一下documentation和例子，但到目前为止没有运气。

它实际上看起来像你不需要你的wine_id和user_id（除非你想允许用户发布其他用户的评论，或者切换他们正在审查的酒）。

这应该为你工作：

@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) 

如果做要允许用户修改两个字段，请编辑你的问题，以显示你的模板或如何在用户提交数据，因为所有的字段都使用hiddenInput小部件，很难说出任何数据会如何进入请求。POST
