Django表单外键下拉框下方额外显示对象问题求助

我创建了一个用于生成模型新对象的表单，其中某外键字段设置为下拉框，但该字段下方额外显示了关联对象信息，预期仅显示下拉框。相关代码如下：

模型代码 #

class VehicleType(models.Model):
    model = models.CharField(max_length=50)
    farekm = models.FloatField()
    capacity = models.IntegerField()

    def __str__(self):
        return self.model


class Vehicle(models.Model):
    type = models.ForeignKey(VehicleType, on_delete=models.CASCADE)
    number = models.CharField(max_length=10)

    def __str__(self):
        return self.number

视图代码 #

def request_cabbie_upgrade(request):
    if request.method == 'POST':
        vehicle_form = VehicleForm(request.POST)
        if vehicle_form.is_valid():
            vehicle = vehicle_form.save(commit=False)
            vehicle.save()
            cabbie_request = CabbieRequest(user=request.user, vehicle=vehicle)
            cabbie_request.save()
            return redirect('PassengerDashboard')
    else:
        vehicle_form = VehicleForm()
    return render(request, 'users/cabbie_request.html', {'vehicle_form': vehicle_form, 'user': request.user})

表单代码 #

class VehicleForm(forms.ModelForm):

    type = forms.ModelChoiceField(queryset=VehicleType.objects.all(), empty_label="Vehicle Type")

    class Meta:
        model = Vehicle
        fields = ['type', 'number']

模板代码 #

{% extends "base.html" %}
{% block title %}
<title>Cabbie Dashboard</title>
{% endblock title %}
{% block body %}
<div class="container mt-5 pt-5 cabbie-dashboard-container">
  <div class="row">
    <div class="col-md-12">
      <h2>Cabbie Information</h2>
      <div class="card">
        <div class="card-body">
          <p><strong>Username:</strong> {{ cabbie.username }}</p>
          <p><strong>First Name:</strong> {{ cabbie.first_name }}</p>
          <p><strong>Last Name:</strong> {{ cabbie.last_name }}</p>
          <p><strong>Email:</strong> {{ cabbie.email }}</p>
          <p><strong>Phone:</strong> {{ cabbie.phone }}</p>
        </div>
      </div>
    </div>
    <div class="col-md-12 mt-4">
      <h2>Request Cabbie Upgrade</h2>
      <form method="post">
        {% csrf_token %}
        <div class="form-group">
          <label for="id_type">Vehicle Type:</label>
          {{ vehicle_form.type }}
        </div>
        <div class="form-group">
          <label for="id_number">Vehicle Number:</label>
          {{ vehicle_form.number }}
        </div>
        <button type="submit" class="btn btn-primary">Submit Request</button>
      </form>
    </div>
  </div>
</div>
{% endblock body %}

问题出在模板中直接渲染表单字段时，Django默认会输出字段的完整HTML（包括可能的帮助文本、关联对象预览等额外内容）。要只显示下拉框，可通过以下两种方式解决：

方式一：修改模板渲染逻辑 #

将模板里的：

{{ vehicle_form.type }}

替换为：

{{ vehicle_form.type.widget }}

这样只会渲染下拉框的<select>标签，不会显示任何额外关联内容。

方式二：在表单类中明确指定Widget #

在表单类中为外键字段指定forms.Select类型的Widget，确保渲染行为符合预期：

class VehicleForm(forms.ModelForm):
    type = forms.ModelChoiceField(
        queryset=VehicleType.objects.all(),
        empty_label="Vehicle Type",
        widget=forms.Select  # 明确指定Widget类型
    )

    class Meta:
        model = Vehicle
        fields = ['type', 'number']
