当表单无效时，我的 HTML 模板中不会显示任何表单错误。表单放置在相关的轮播中。
我正在调用单个表单元素，而不是呈现为 {{form.as_p}}，在这种情况下显示错误。
轮播中的最后一项是密码，如果我将其留空，它将显示一个弹出窗口，上面写着“请填写此字段”，但仅此而已，并且仅适用于该字段。

if request.method == 'POST':

user = create_user_form.save()
safezone = safezone_form.save(commit=False)
safezone.userid = user
safezone.useremail = user.email
safezone.save()

答案 0 :(得分：1)
您的错误不会显示，因为如果您的表单无效，您将重定向到另一个页面。
if create_user_form.is_valid() and safezone_form.is_valid():
...
return redirect('safezoneaddedpage')
return redirect('safezoneaddedpage') # detelete this, here you must not redirect to another page, but render the same template.
并添加：
return render(request, 'V2maparonno_create_safe_zoneV2.html',
{'create_user_form': create_user_form, 'safezone_form': safezone_form})
