如何从 Django-Widget-Tweaks 表单字段中删除 required
How to remove required from Django-Widget-Tweaks form field
我正在尝试从 django-widget-tweaks 表单中删除必需的属性。
我试过了:
{% render_field form.legal_entity|attr:'required:false' placeholder=form.legal_entity.label class+="form-control" %}
和
{% render_field form.legal_entity|remove_attr:"required" placeholder=form.legal_entity.label class+="form-control" %}
无论我做什么,结果总是:
<input type="text" name="legal_entity" maxlength="120" class="form-control" placeholder="Firmenname" required id="id_legal_entity">
这是相应的表格:
class MerchantForm(forms.ModelForm):
class Meta:
model = Merchant
fields = ['name', 'legal_entity', 'legal_address','legal_zip', 'legal_city','address', 'zip', 'city', 'contact_person', 'phone', 'email']
def clean_legal_entity(self):
data = self.cleaned_data['legal_entity']
return data
...
在您 HTML 页面的 JS 代码中:
window.onload=myfunction();
function myfunction()
{
$("input").removeAttr("required");
$("select").removeAttr("required");
$("textarea").removeAttr("required");
}
您可以通过在相应字段中设置 required=False
[Django-doc] 将字段标记为非必填:
class MerchantForm(forms.ModelForm):
legal_entity = forms.CharField(<b>required=False</b>)
class Meta:
model = Merchant
fields = ['name', 'legal_entity', 'legal_address','legal_zip', 'legal_city','address', 'zip', 'city', 'contact_person', 'phone', 'email']
