Question

我正在按照以下教程学习如何创建Django表单。我真的坚持为什么表单没有出现在指定的html页面上。

这是我的代码：

评论/ url.py

urlpatterns = [
    url(r'^$', views.review_list, name='review_list'),
    url(r'^review/(?P<review_id>[0-9]+)/$', views.review_detail, name='review_detail'),
    url(r'^wine/$', views.wine_list, name='wine_list'),
    url(r'^wine/(?P<wine_id>[0-9]+)/$', views.wine_detail, name='wine_detail'),
    url(r'^wine/(?P<wine_id>[0-9]+)/add_review/$', views.add_review, name='add_review')]

评论/ Forms.py

from django.forms import ModelForm, Textarea
from reviews.models import Review

class ReviewForm(ModelForm):
    class Meta:
        model = Review
        fields = ('user_name', 'rating', 'content')
        widgets = {
            'content': Textarea(attrs={'cols': 40, 'rows': 15})
        }

的评价/ Views.py：

# View that provides wine information and reviews
def wine_detail(request, wine_id):
    wine = get_object_or_404(Wine, pk=wine_id)
    return render(request, 'reviews/wine_detail.html', {'wine': wine})

# View that contains add review form
def add_review(request, wine_id):
    wine = get_object_or_404(Wine, pk=wine_id)
    form = ReviewForm(request.POST)
    if form.is_valid():

        # Retrieves values entered
        rating = form.cleaned_data['rating']
        content = form.cleaned_data['content']
        user_name = form.cleaned_data['user_name']

        review = Review()
        review.wine = wine
        review.user_name = user_name
        review.rating = rating
        review.content = content
        review.pub_date = datetime.datetime.now()
        review.save()
        return HttpResponseRedirect(reverse('reviews:wine_detail', args=(wine.id,)))

    return render(request, 'reviews/wine_detail.html', {'wine': wine, 'form': form})

模板

<h2>{{ wine.name }}</h2>
<h5>{{ wine.review_set.count }} reviews ({{ wine.average_rating | floatformat }} average rating)</h5>

<h3>Recent reviews</h3>

{% if wine.review_set.all %}
<div>
    {% for review in wine.review_set.all %}
    <div>
        <em>{{ review.content }}</em>
        <h6>Rated {{ review.rating }} of 5 by {{ review.user_name }}</h6>
        <h5>
            <a href="{% url 'reviews:review_detail' review.id %}">
                Read more </a>
        </h5>
    </div>
    {% endfor %}
</div>
{% endif %}

<h3>Add your review</h3>
{% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %}

<form action="{% url 'reviews:add_review' wine.id %}" method="post">
        {% csrf_token %}
        {{ form.as_p }}
    <input type="submit" value="Add" />
</form>

以下是现在的截图：

显然，您可以看到在没有输入表单的情况下生成表单元素。我认为{{form.as_p}}可能是错的。我不知道为什么会这样。我检查了语法，我没有发现任何会导致表单丢失的错误。任何帮助将非常感激。

以下是它应该是什么样子：

表格没有出现
