django - form.cleaned_data返回空集

我有一个表格：

class OrderForm(forms.Form):
    delivery_time = models.CharField(max_length=100)
    address_city = models.CharField(max_length=40)
    address_street = models.CharField(max_length=40)
    address_building = models.CharField(max_length=40)

这是我的看法：

def submit(request):
    args = {}
    args['form'] = OrderForm()
    if request.POST:
        order_form = OrderForm(request.POST)
        if order_form.is_valid():
            user = request.user
            address_city = order_form.cleaned_data.get('address_city')
            address_street = order_form.cleaned_data.get('address_street')
            address_building = order_form.cleaned_data.get('address_building')
            delivery_time = order_form.cleaned_data.get('delivery_time')
            new_order = Order(address_city=address_city,
                              address_street=address_street,
                              address_building=address_building,
                              delivery_date=delivery_time, client=user)
            new_order.save()
            Basket.objects.filter(client=user).delete()
            return redirect('/order/')
        else:
            args['form'] = order_form
    else:
        return render(request, 'order_page.html', args)

我猜问题出在我的模板上：

<form class="form-horizontal" action="{% url 'order_submit' %}" method="post">
        {% csrf_token %}
        <div class="control-group">
            <label class="control-label" for="address">City<sup>*</sup></label>
            <div class="controls">
                <input type="text" id="address" placeholder="City name" name="address_city">
            </div>
        </div>

        ...

我想问题是我不仅仅使用{{form}}。但是我确实需要这些样式来构成我的表单。我对我的注册模板也做同样的事情，并且可以正常工作。注册表单继承了UserCreationForm并受User模型限制，但是我的OrderForm继承了form.Form。会是什么

Order model:
class Order(models.Model):
    state_choices = ('ACTIVE', 'COMPLETED', 'FROZEN')
    order_date = models.DateTimeField(auto_now_add=True)
    delivery_time = models.CharField(max_length=100)
    address_city = models.CharField(max_length=40)
    address_street = models.CharField(max_length=40)
    address_building = models.CharField(max_length=40)
    state = models.CharField(max_length=200, default='ACTIVE')
    client = models.ForeignKey(CustomUser)

最佳答案

这里的基本问题在表单的定义之内。表单不适用于模型字段，但需要表单字段。只有这样才能正确构建字段。

from django import forms

class OrderForm(forms.Form):
    delivery_time = forms.CharField(max_length=100)
    address_city = forms.CharField(max_length=40)
    address_street = forms.CharField(max_length=40)
    address_building = forms.CharField(max_length=40)

之后，尝试在模板中输出{{ form }}。

    <form action="foo" method="post">
        {% csrf_token %}
        {{ form }}
        <input type="submit" value="submit"/>
    </div>
