从 Django 十进制 ModelForm 字段中删除向上和向下箭头

Question

我的十进制 ModelForm 字段在增加/减少字段值的字段中显示为“向上/向下箭头”。

关于如何删除/隐藏这些箭头的任何反馈？

形式：

class PriceAssessment1Form(forms.ModelForm):
    class Meta:
        model = Component
        fields = ['size_height','size_width','size_length','weight','base_material_price']

模型

class Component(models.Model):

    name = models.CharField(max_length=255)
    created_date= models.DateTimeField(default=datetime.now)
    user = models.ForeignKey(User)
    price_assessment_started = models.BooleanField(default=False)

    size_height = models.DecimalField(null=True,blank=True, max_digits=9, decimal_places=2)
    size_width = models.DecimalField(null=True,blank=True, max_digits=9, decimal_places=2)
    size_length = models.DecimalField(null=True,blank=True, max_digits=9, decimal_places=2)

    weight = models.DecimalField(null=True,blank=True, max_digits=9, decimal_places=2)

    base_material_price = models.DecimalField(null=True,blank=True, max_digits=9, decimal_places=2)

模板

<form action="{% url 'portal_price_assessment' component_id %}" method="post"> {% csrf_token %}
            <div>
                <div>size_height {{ form.size_height }}</div>
                <div>size_width {{ form.size_width }}</div>
                <div>size_length {{ form.size_length }}</div>
                <div>weight {{ form.weight }}</div>
                <div>base_material_price {{ form.base_material_price }}</div>
             </div>
            <div style="margin-top:18px;">
                <a href="{% url 'portal_home' %}" class="btn btn-link">Cancel</a>
                <button class="btn" type="submit" >&nbsp;Save & Close</button>
            </div>
        </form>

您可以覆盖 ModelForm 字段以使用您喜欢的任何小部件，如下所示：

class AuthorForm(ModelForm):

    class Meta:
        model = Author
        fields = ('name', 'title', 'birth_date')
        widgets = {
            'name': TextInput(attrs={'placeholder': 'That dude cray'}),
        }
