有人知道怎么回事吗？我有一个 wsgi 错误。我想添加一些信息来评分，特别是日期。但是，我收到此 wsgi 错误:

这是一个 View :

template_name = "policy/pay_date_modal_form.html"
rate = get_object_or_404(PaymentRate, id=paymentrate_id)

form.save()
return JsonResponse({'success': True})
return render_to_response(template_name, {

'rate': rate
}, context_instance=RequestContext(request))
模板:
{% extends "base_form.html" %}
{% block "additional" %}
<script type="text/javascript">
$(document).ready(function(){
$("#{{form.name.auto_id}}").blur(function(){
if(!$('#{{form.short_name.auto_id}}').val()) {
$('#{{form.short_name.auto_id}}').val($("#{{form.name.auto_id}}").val());
}
});
});
$("#add_pay_date_form").submit(function (e) {
e.preventDefault();
var formData = new FormData($(this)[0]);
$.ajax({

success: function (response, status, xhr) {
if (xhr.getResponseHeader('Content-Type') == 'application/json')
{ console.log(xhr.getResponseHeader('Content-Type'));
$.magnificPopup.close();
} else {
$('#{{ form.helper.form_id }}_panel').replaceWith(response);
}
}
});
console.log('test');
});
</script>
{% endblock "additional" %}
和网址:
url(r'add_paydate_form/(?P<paymentrate_id>\d+)/$', add_pay_date_form, name='add_pay_date_form'),
我有这个错误，我不知道为什么。也许扩展基本形式有问题？
请您参考如下方法:
这是错误的:
form = PayDateForm(request, PaymentRate)
您没有将request 对象传递给表单，您传递的是提交的表单数据，即
form = PayDateForm(request.POST, PaymentRate)
(解释一下:你得到的错误是因为 Django 期待一个类似 dict 的对象，所以它试图调用它的 get 方法来获取特定的数据键，因此 'WSGIRequest' 对象没有属性 'get')
所以你的 View 应该是这样的:
@login_required
def add_pay_date_form(request, paymentrate_id):
template_name = "policy/pay_date_modal_form.html"
rate = get_object_or_404(PaymentRate, id=paymentrate_id)
form = PayDateForm(request.POST or None, PaymentRate)
if form.is_valid():
form.save()
return JsonResponse({'success': True})
return render_to_response(template_name, {
'form': form,
'rate': rate
}, context_instance=RequestContext(request))
