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其对象列表。
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')

OR

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，但也没有任何效果。
在将错误代码插入post_save时，我得到一条错误消息-确实会触发该错误消息，但重定向不会发生。

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激-由于我在这个简单问题上呆了几天。

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

谢谢

推荐答案

您可以覆盖 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中返回响应。您不想覆盖 change_view ，因为那样既可以保存表单，又可以返回响应。

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.
