在Bootstrap表單中使用外鍵的Django下拉列表

Question

我正在開發我的第一個Django網站，我想在Bootstrap表單中使用外鍵下拉。 我可以通過手動輸入外鍵號（例如“1”）來添加外鍵，表單將起作用。 但我無法為鏈接下拉列表插入正確的語法。 在下面找到我當前的models.py / views.py和html

我有以下客戶模型;

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)

請參閱下面的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>

任何幫助深表感謝。

Answer 1

首先，我想建議使用django-crispy-forms ，你不會后悔，它與bootstrap配對非常好。 我換了之后，我不明白我如何使用內置的django表格這么久。

話雖這么說，這里有一個jsfiddle演示如何使用bootstrap下拉列表作為輸入項。

下拉按鈕w / .form-control

 <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> 

然后在您的視圖中確保傳入types = CustomerType.objects.all()

Answer 2

要在您的下拉列表中添加客戶類型，您必須從表中收集所有客戶類型：

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))

（不要忘記在模型中包含CustomerType）

然后你必須將它們包含在你的元素中

<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>

Answer 3

我變了

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

至

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

現在它保存了Key但顯示了ValueText

html部分的最終結果

<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>

views.py的最終結果

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))
