python - 发布 JSON 数据后，Django 重定向不起作用

Question

接收到 json 数据后，返回重定向在 else 语句中不起作用。相同的重定向适用于另一个 if 语句。在终端中，我可以看到我想要重定向到的 url 的 GET 请求，这就是为什么我觉得这很奇怪。打印语句在 else 中完美运行，只有重定向失败。到目前为止我的代码：

views.py （如果需要其他观点来回答问题，请告诉我）

def data_type_error_handling(request):
    '''handles all the possible choices after data_type_errors '''
    if '_skip' in request.POST:
        return redirect('data_validation')
    elif 'first_load' in request.session or '_refresh' in request.POST or request.method == 'GET':
        print("data_load vagy refresh")
        error_list = request.session['error_list']
        errors = json.dumps(error_list, indent=4, sort_keys=True, default=str)
        if 'first_load' in request.session:
            del request.session['first_load']
        return render(request, "upload/data-type-correction.html",
                                                 {"error_list": errors})
    else:
        raw_data = request.body.decode('utf-8')
        data = json.loads(raw_data)
        print(data)
        return redirect('data_validation')

def data_validation(request):
    return render(request, "upload/data-validation.html")

return redirect('data_validation') 在第一个 if 语句中有效，但在 else 中无效，它停留在我单击按钮的同一页面上。

from . import views

urlpatterns=[
    path('data-upload', views.data_upload, name='data-upload'),
    path('upload-failed', views.data_upload, name='upload-failed'),
    path('upload-successful', views.data_upload, name='upload-successful'),
    path('data-type-correction', views.data_type_error_handling, name ='data-type-correction'),
    path('data-validation', views.data_validation, name ='data_validation'),
]
