Python 带有引导形式外键的Django下拉列表

我正在开发我的第一个Django网站，我想使用一个外键下拉式引导形式。我可以通过手动输入外键号（例如“1”）来添加外键，表单将正常工作。但我无法为链接下拉列表插入正确的语法。在下面找到my current models.py/views.py和html

我有以下客户模型

class Customer(models.Model):
    customer_type = models.ForeignKey(CustomerType)
    customer_name = models.CharField(max_length=120, null=True, blank=True)

    def __unicode__(self):
        return smart_unicode(self.customer_name)

使用CustomerType

class CustomerType(models.Model):
    customer_type = models.CharField(max_length=120, null=True, blank=True)

    def __unicode__(self):
        return smart_unicode(self.customer_type)

请参见下面的my views.py

def customeradd(request):      
    form = CustomerAddForm(request.POST or None)

    if form.is_valid():
        save_it = form.save(commit=False)
        save_it.save()
        messages.success(request, 'Customer added succesfully')
        return HttpResponseRedirect('/customeroverview/')

    return render_to_response("customer-add.html",
                              locals(),
                              context_instance=RequestContext(request))

最后是我的html

<div class="col-lg-12">
          <form class="form-horizontal" method="POST" action=''> {% csrf_token %}

            <div class="form-group">
              <label for="customer_name" class="col-sm-2 control-label">Customer Name</label>
              <div class="col-sm-10">
                <input id="customer_name"  name="customer_name" type="text" class="form-control" >
              </div>
            </div>

        <div class="form-group">
              <label for="customer_type" class="col-sm-2 control-label">Customer Type</label>
              <div class="col-sm-10">
        <select class="form-control" id="customer_type" name="customer_type"></select>
          </div>
            </div>

            <div class="form-group">
            <div class="col-sm-10"></div>
              <div class="col-sm-2">
                <button type='submit' class="btn btn-success btn-block">Add Customer</button>
              </div>
            </div>

          </form>
</div>

{%csrf_令牌%}
客户名称
客户类型
添加客户

非常感谢您提供的任何帮助。

首先，我建议您使用，您不会后悔，它与bootstrap非常匹配。切换之后，我不明白我是如何长期使用内置的django表单的

也就是说，这里演示了如何将引导下拉列表用作输入项

下拉按钮w/.form控件

<div class="panel panel-default">
    <div class="panel-body">
       <div class="btn-group">
         <button type="button" class="btn btn-default dropdown-toggle form-control" data-toggle="dropdown">
           <span data-bind="label">Select One</span>&nbsp;<span class="caret"></span>
         </button>
         <ul class="dropdown-menu" role="menu">
             {% for t in types %}
                 <li><a href="#">{{ type }}</a></li>
             {% enfor %}
         </ul>
      </div>
   </div>
</div>

选择一个

{%t在类型%}

{%enfor%}

---

然后在视图中确保传入

types=CustomerType.objects.all（）

要在下拉列表中添加客户类型，首先必须从表中收集所有客户类型：

def customeradd(request):      
    form = CustomerAddForm(request.POST or None)
    customer_types = CustomerType.objects.all()

    if form.is_valid():
        save_it = form.save(commit=False)
        save_it.save()
        messages.success(request, 'Customer added succesfully')
        return HttpResponseRedirect('/customeroverview/')

    return render_to_response("customer-add.html",
                              {'customer_types': customer_types},
                              context_instance=RequestContext(request))

（别忘了包括模型中的CustomerType）

然后你必须将它们包含到你的元素中

<div class="col-lg-12">
          <form class="form-horizontal" method="POST" action=''> {% csrf_token %}

            <div class="form-group">
              <label for="customer_name" class="col-sm-2 control-label">Customer Name</label>
              <div class="col-sm-10">
                <input id="customer_name"  name="customer_name" type="text" class="form-control" >
              </div>
            </div>

        <div class="form-group">
              <label for="customer_type" class="col-sm-2 control-label">Customer Type</label>
              <div class="col-sm-10">
        <select class="form-control" id="customer_type" name="customer_type"> {%for type in customer_types%}<option value="{{type}}">{{type}}</option>{%endfor%}</select>
          </div>
            </div>

            <div class="form-group">
            <div class="col-sm-10"></div>
              <div class="col-sm-2">
                <button type='submit' class="btn btn-success btn-block">Add Customer</button>
              </div>
            </div>

          </form>
</div>

{%csrf_令牌%}
客户名称
客户类型
{%for客户类型中的类型{u类型%}{{type}{%endfor%}
添加客户

我改变了

<option value="{{type}}">{{type}}</option>

您的元素为空。你从那里剪下代码了吗？是的，那里现在没有代码了。这就是我想要调用customertype表的内容到select中的原因。但我不知道语法。请阅读有关ModelForms的内容。django站点教程非常值得花几个小时来探索。现在CustomerType中的值可以从select中获得，谢谢！但是，表单无法保存，因为我认为它试图保存customer_类型的值，而不是该值的外键。我是否需要在表单中调整/添加一些内容。py？谢谢你提供的crispy表单建议，我会研究的！

<option value="{{type.id}}">{{type}}</option>

<div class="form-group">
    <label for="customer_type" class="col-sm-2 control-label">Customer Type</label>
     <div class="col-sm-10">
       <select class="form-control" id="customer_type" name="customer_type">
          {%for type in customer_types%}<option value="{{type.id}}">{{type}}</option>{%endfor%}
        </select>
     </div>
</div>

def customeradd(request):      
    form = CustomerAddForm(request.POST or None)
    customer_types = CustomerType.objects.all()

    if form.is_valid():
        save_it = form.save(commit=False)
        save_it.save()
        messages.success(request, 'Customer added succesfully')
        return HttpResponseRedirect('/customeroverview/')

    return render_to_response("customer-add.html",
                              {'customer_types': customer_types},
                              context_instance=RequestContext(request))
