[教师登录他们的帐户后，他/她可以更新学生的行为，而在教师更新其学生的学生行为后，将显示弹出消息（加甜消息）

场景：

这是我想要的结果

这是我的参考：https://github.com/Atrox/sweetify-django

def Updatestudentbehavior(request):
    ...
    sweetify.success(request, 'You did it', text='Good job! You successfully showed a SweetAlert message',
                     persistent='Hell yeah')

    **#update data without refreshing page and popup message will appear**


def teacher(request):
    if request.method != 'POST':
        raise Http404('Only POSTs are allowed')
    try:
         ......
         return render(request, 'Homepage/index.html')
    except EmployeeUser.DoesNotExist:
        messages.warning(request, 'Your Username and password are Incorrect.')
        ….
    return render(request, 'Homepage/TeacherLogin.html')

def corevalues(request):
    ...
    if StudentsBehaviorGrades.objects.filter(Teacher = teacher).exists():

        ….

        return render(request, 'Homepage/updatebehavior.html',
                      {'studentsbehaviorgrade':studentsbehaviorgrade,'student':student,'teacher': teacher, 'behavior': behavior, 'behaviorperlevel': behaviorperlevel,
                       "behaviorperlevels": behaviorperlevels, "period": period})
    else:
        ….
        return render(request, 'Homepage/behavior.html',
                      {'teacher': teacher, 'behavior': behavior, 'behaviorperlevel': behaviorperlevel,
                       "behaviorperlevels": behaviorperlevels, "Students": Students, "period": period})

urls.py

path('teacher/', Homepage.views.teacher, name='teacher'),
path('Updatestudentbehavior/', Homepage.views.Updatestudentbehavior, name='Updatestudentbehavior'),

我的settings.py

INSTALLED_APPS = [
    ….
    'sweetify',
]

SWEETIFY_SWEETALERT_LIBRARY = 'sweetalert2'

我的html

{% load sweetify %}
{% sweetify %}
….
<form class="myform" action="{% url 'Updatestudentbehavior' %}" method="POST"  style="width: 100%" >{% csrf_token %}
    ….
    <input type="submit" value="Update" class="myform">
</form>
<script type="text/javascript">
   $(document).on('submit', '.myform', function(e) {
      e.preventDefault();
      console.log(this);
        $.ajax({
            type:'POST',
            url:'{% url 'Updatestudentbehavior' %}'
            data:{
                teacher:$('#teacher').val(),
                student:$('#student').val(),
                marking:$('#marking').val(),
                csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val()
            },
            success:function(){
                alert('Update Success');
            }
        });
   });
</script>
<script src="https://code.jquery.com/jquery-3.1.0.min.js"></script>
</body>
</html>

UPDATE

当我尝试这个时

def Updatestudentbehavior(request):
     ….
     sweetify.success(request, 'You did it', text='Good job! You successfully showed a SweetAlert message',
                 persistent='Hell yeah')
     return redirect(request.path_info)

这是我得到的错误

这是从终端来的

Answer 1

错误本身非常清楚。该页面已被重定向太多次。这是因为您在return redirect(request.path_info)视图中使用了Updatestudentbehavior。

如果您查看documentation，您会注意到request.path_info是当前视图本身的URL。这意味着该视图反复将请求重定向到自身，从而导致浏览器中的错误。

而不是使用request.path_info，请使用从其生成请求的页面的URL。
