django-admin:保存对象后如何重定向到另一个 URL? [英] django-admin: How to redirect to another URL after Object save?

问题描述

在 Django Admin 中，保存对象总是返回到它的对象列表.现在我想在保存付款对象后转到发票对象列表.

In Django Admin, saving an Object always goes back to it's List of Objects. Now i want to go to the List of Invoice-Objects upon saving a Payment-Object.

我尝试了几件事:

在 admin.py 中:

In admin.py:

@receiver(post_save, sender=Payment)
def custom_redirect(sender, instance, **kwargs):
    return HttpResponseRedirect('/admin/sales/invoice')

或

class PaymentAdmin(VersionAdmin, admin.ModelAdmin):
    def change_view(self, request, object_id, extra_context=None):
        return HttpResponseRedirect('/admin/sales/invoice')

我尝试使用 redirect() 而不是 HttpResponseRedirect ，但也没有效果.在将错误代码插入 post_save 时，我收到一条错误消息 - 所以它会被触发，但不会发生重定向.

Instead of HttpResponseRedirect i tried using redirect() , but also with no effect. On inserting wrong code into post_save i get an error message - so it does get triggered, but the redirect does not happen.

任何提示都会非常感谢 - 因为我在这个简单"问题上被困了好几天.

Any hints would be very apreciated - as i'm stuck for days on this "simple" problem.

谢谢

推荐答案

你可以覆盖 response_add 和 response_change 方法.

You can override the response_add and response_change methods.

from django.shortcuts import redirect

class PaymentAdmin(VersionAdmin, admin.ModelAdmin):
    def response_add(self, request, obj, post_url_continue=None):
        return redirect('/admin/sales/invoice')

    def response_change(self, request, obj):
        return redirect('/admin/sales/invoice')

不可能从信号处理程序内部返回响应.您不想覆盖 change_view，因为它会处理保存表单以及返回响应.

It isn't possible to return a response from inside a signal handler. You don't want to override change_view because that handles saving the form as well as returning the response.
