Django:将一个应用程序中的表单添加到另一个应用程序模板中(详细视图)

我想为用户添加一个表单,以添加评分和评论注释,从而从另一个应用程序(评分应用程序和项目应用程序)更新模型。 我已经为此苦苦挣扎了一段时间。 现在我有:

评分MODELS.py

class Avaliacao(models.Model):
    RATING_CHOICES = (
        (1, '1'),
        (2, '2'),
        (3, '3'),
        (4, '4'),
        (5, '5'),
    )
    created_at = models.DateTimeField(auto_now=True)
    usuario = models.ForeignKey(get_user_model(),on_delete=models.CASCADE)
    safra = models.ForeignKey(Safra,blank=False,on_delete=models.SET_NULL,null=True)
    nota = models.IntegerField(choices=RATING_CHOICES)
    comment = models.TextField()

forms.py

class NotaFormulario(ModelForm):
    class Meta:
        model = Avaliacao
        fields = ['nota','comment']

urls.py

urlpatterns = [
    url(r'^safra/(?P<safra_id>[0-9]+)/add_review/$',views.add_review, name='add_review')
]

views.py

def add_review(request, safra_id):
    safra = get_object_or_404(Safra, pk=safra_id)
    form = NotaFormulario(request.POST)

    if form.is_valid():
        nota = form.cleaned_data['nota']
        comment = form.cleaned_data['comment']
        usuario = request.user
        avaliacao = Avaliacao()
        avaliacao.safra = safra
        avaliacao.usuario = usuario
        avaliacao.nota = nota
        avaliacao.comment = comment
        avaliacao.created_at = datetime.datetime.now()
        avaliacao.save()

        # Always return an HttpResponseRedirect after successfully dealing
        # with POST data. This prevents data from being posted twice if a
        # user hits the Back button.
        return HttpResponseRedirect(reverse('vinhos:safra_detalhes', args=(safra.id,)))


    return render(request, 'vinhos/safra_detail.html', {'safra': safra, 'formulario': form})

template.html(这是我从另一个应用程序获得的详细信息模板)

<form action="{% url 'notas:add_review' safra.id %}" method="post" >
  {% csrf_token %}
  {{ formulario }}
  <input type="submit" value="Enviar" class="btn btn-primary btn-large">


</form>

表单所在的模板(其他应用程序的详细视图页面)的urls.py路径为

path('safra/<int:pk>/',views.SafraDetalhes.as_view(), name='safra_detalhes'),

字段未呈现。 HTML看起来像这样:

<form action="/safra/6/add_review/" method="post" >
  <input type="hidden" name="csrfmiddlewaretoken" value="ofbt2lvghvsNhPuSVRDtAgP3gYoGI55AIoXcA8EpUE29Sp">

  <input type="submit" value="Enviar" class="btn btn-primary btn-large">


</form>

该表单仅在我点击一次send后呈现,然后呈现“此字段为必填”警告。

总的来说,我一直在Django中苦苦挣扎,因为在我要开发的应用程序上,总是有这种形式的横截面在一个应用程序的模型上创建实例,而在另一个模型的详细视图上创建实例来自另一个应用程序。
