Python 德扬戈：我能'；t在表单集中添加多行时不会出现错误

我在处理Django项目时发现了一个错误。为了总结这个问题，每次我尝试向一个表单集中添加多行时，都会得到一个

multivaluedictkeyrorm

错误

每次我尝试提交表单时，即使我没有更改表单集，错误仍然存在

这是我的代码：View.py

def profile(request):
    # Get the user's profile
    try:
        profile = Profile.objects.get(user = request.user.id)
    except:
        profile = Profile()
        profile.user = request.user

    # inline formset for profile's pony
    PonyFormset = inlineformset_factory(Profile, Pony, fields=('pony','message',), extra = 2)

    # inline formset for profile's url
    UrlFormset = inlineformset_factory(Profile, Url, fields=('url',), extra = 2)

    if request.method == 'POST':

        form = ProfileForm(request.POST, request.FILES, instance = profile)
        ponies = PonyFormset(request.POST, instance = profile, prefix = "pony")
        urls = UrlFormset(request.POST, instance = profile, prefix = "url")

        if form.is_valid():
            form.save()
            form = ProfileForm(instance = profile)

        if ponies.is_valid():
            ponies.save()
            ponies = PonyFormset(instance = profile, prefix = "pony")

        if urls.is_valid():
            urls.save()
            urls = UrlFormset(instance = profile, prefix = "url")

    else:
        form = ProfileForm(instance = profile)
        ponies = PonyFormset(instance = profile, prefix = "pony")
        urls = UrlFormset(instance = profile, prefix = "url")

    return render(request, 'profile.html', {
        'profile': profile,
        'form':    form,
        'ponies':  ponies,
        'urls':    urls,
    })

Model.py

class Pony(models.Model):
    ''' List of ponies with little quotes to display in the user's description '''

    profile = models.ForeignKey(Profile)
    pony    = models.CharField(max_length = 32)
    message = models.CharField(max_length = 64)

    def __str__(self):
        try:
            return self.message % self.pony
        except TypeError:
            return self.message

    class Meta:
        verbose_name_plural = "ponies"

class Url(models.Model):
    ''' List of urls in the user's description '''

    profile = models.ForeignKey(Profile)
    url     = models.URLField()
    icon    = models.CharField(max_length = 16)

    def __str__(self):
        return self.url

模板

<h3>{% trans 'Url :' %}</h3>
                <!-- url -->
                {{ urls.management_form }}
                {% for urlform in urls %}
                    {% if ponies.can_delete %}
                        {% bootstrap_field urlform.url show_label=false field_class='col-xs-11' form_group_class='' %}
                        {% bootstrap_field urlform.DELETE %}
                    {% else %}
                        {% bootstrap_field urlform.message show_label=false field_class='col-xs-12' %}
                    {% endif %}
                {% endfor %}

{%trans'Url:'%1}
{{url.management_form}
{%用于URL%中的urlform}
{%if ponies.can_delete%}
{%bootstrap_field urlform.url show_label=false field_class='col-xs-11'form_group_class=''%}
{%bootstrap_字段urlform.DELETE%}
{%else%}
{%bootstrap_field urlform.message show_label=false field_class='col-xs-12'%}
{%endif%}
{%endfor%}

（我只放置Url表单集，因为小马表单集是相同的）

和错误（对于多个url）

我想我把这个问题的所有东西都放在这里了，如果你需要更多，我可以加上。提前谢谢你帮助我

您需要在表单集中包含每个表单的

id

字段（它是一个隐藏字段，因此不会向用户显示）

通常，您可以在模板中执行此操作：

{% for form in formset %}
    {{ form.id }}
    ...

就你而言：

{% for urlform in urls %}
    {{ urlform.id }}

---

您可能需要为其他表单集执行类似的操作。

好的，可以了。谢谢您的帮助，我不知道这个隐藏字段。根据我的猜测，它的目标是分离表单集的每个表单。是吗？我不知道你说的“分开每个表格”是什么意思。据说包含主键字段是一项要求。我错过了文档的这一部分。我会更加小心的，再次谢谢你
