Question

我有一个shipment_details表单，其中包含有关装运的一些信息以及装运顺序中的所有项目。有两个模型信息一个发货另一个是项目模型。我想使用复选框更新所有Marco Item Shipped值（请参阅表单视图图片）。这是我的表单视图 http://imgur.com/a/dcNZE 这是我的forms.py，其中我将项目链接到项目is_shipped字段，此值显示在视图中使用{{form_status.as_p}}。的 forms.py

class ShipmentStatus(forms.CheckboxInput):
    input_type = 'checkbox'

class ShipmentStatusForm((forms.ModelForm)):
    class Meta:
        model = Items
        fields = ['is_shipped']
        widgets = {
            'is_shipped': ShipmentStatus(),
        }

这是我的视图模型的 shipment_detail.html

{% extends "_dashboardlayout.html" %}

{% block content %}

<div id="page-wrapper">
    <div class="row">
        <div class="col-lg-12">
            <h2 class="page-header">Shipment Details</h2>
        </div>
        <div class="col-md-12">
            <form method="POST" action="">
                {% csrf_token %}
                {{ form.as_p }}
                <table class="table table-striped">
                    <tr>
                        <th>Item No</th>
                        <th>SKU</th>
                        <th>Quantity</th>
                        <th>Price</th>
                        <th>Marco Item</th>
                        <th>Marco Item Shipped</th>
                    </tr>
                    {% for item in items_queryset %}
                    <tr>
                        <td>{{ item.item_no }}</td>
                        <td>{{ item.sku }}</td>
                        <td>{{ item.requested_quantity }}</td>
                        <td>{{ item.price }}</td>
                        <td>{{ item.is_send }}</td>
                        <td>{{ form_status.as_p }}</td>
                    </tr>
                    {% endfor %}
                </table>
                <input type="submit" value="Save">
            </form>

        </div>
    </div>
    <!-- /.row -->
</div>

{% endblock %}

这是我的控制py文件

def shipment_detail(request, order_id=None):
    order_queryset = Order.objects.get(order_id=order_id)
    customer_queryset = Customer.objects.all()
    address_queryset = Address.objects.all()
    items_queryset = Items.objects.filter(order_id=order_id).order_by('item_no')
    shipment_queryset = Shipment.objects.filter(order_id=order_id)
    # if there is no shipment data then generate shipment details for the Order
    if not shipment_queryset:
        form = ShipmentForm(request.POST or None)
        form_status = ShipmentStatusForm(request.POST or None)
        if form.is_valid():
            instance = form.save(commit=False)
            instance.order_id = order_queryset
            order_queryset.save()
            instance.save()

        # save item status
        if form_status.is_valid():
            instance = form_status.save(commit=False)
            instance.save()

        context = {
            "form": form,
            "form_status": form_status,
            "order_queryset": order_queryset,
            "customer_queryset": customer_queryset,
            "address_queryset": address_queryset,
            "items_queryset": items_queryset,
        }
        return render(request, "shipment_detail.html", context)
    # if there is already data then updated the shipment details for the Order
    else:
        instance = get_object_or_404(Shipment, order_id=order_id)
        form = ShipmentForm(request.POST or None, instance=instance)

        if form.is_valid():
            instance = form.save(commit=False)
            instance.order_id = order_queryset
            # updated order is_shipped field according to ship_status
            if instance.status == True:
                order_queryset.is_shipped = True

            if instance.status == False:
                order_queryset.is_shipped = False

            # updated order is_completed field according to shipment is_complete field
            if instance.is_complete == True:
                order_queryset.is_completed = True

            if instance.is_complete == False:
                order_queryset.is_completed = False

            order_queryset.save()

            instance.save()

        print "form  status"

        # updated item is_shipped field
        instance_status = get_list_or_404(Items, order_id=order_id)

        for instance in instance_status:
            form_status = ShipmentStatusForm(request.POST, instance=instance)
            if form_status.is_valid():
                instance = form_status.save(commit=False)
                instance.save()

        context = {
            "form": form,
            "instance": instance,
            "form_status": form_status,
            "order_queryset": order_queryset,
            "customer_queryset": customer_queryset,
            "address_queryset": address_queryset,
            "items_queryset": items_queryset,
        }
        return render(request, "shipment_detail.html", context)

这里的问题是，当点击所有Marco项目发货时，如果正确地点击了它的保存值，如果我点击一个假，则另一个为真，那么它就不会保存价值。

执行此操作的一种方法是使用对象的pk作为复选框的值

<input type="checkbox" value='{{item.id}}' 
                         name='for_action' id='for_action' >

，您可以使用request.POST.getlist('for_action')

在视图中获取这些pk的列表

在这里你去!!

HTML：

<div class="col-lg-12">
        <h2 class="page-header">Shipment Details</h2>
    </div>
    <div class="col-md-12">
        <form method="POST" action="">
            {% csrf_token %}
            {{ form.as_p }}
            <table class="table table-striped">
                <tr>
                    <th>Item No</th>
                    <th>SKU</th>
                    <th>Quantity</th>
                    <th>Price</th>
                    <th>Marco Item</th>
                    <th>Marco Item Shipped</th>
                </tr>
                {% for item in items_queryset %}
                <tr>

                    <td>{{ item.sku }}</td>
                    <td>{{ item.requested_quantity }}</td>
                    <td>{{ item.price }}</td>
