Django Admin删除默认保存消息

Question

我已在模型管理员中添加了此额外消息，基本上我想删除默认消息。有没有人可以帮助我做到这一点？

我的实际信息：

def save_model(self, request, obj, form, change):
        # add an additional message
        user = request.user
        messages.info(request, "Dear " + str(user)+ " "+ " please note that your parking plot has been reserved")
        super(ParcareModelAdmin, self).save_model(request, obj, form, change)

默认有点烂！

谢谢！

我解决了以下问题，尽管它不是很优雅，但是可以工作：

from django.contrib import messages
from django.contrib import admin

# Register your models here.
from . import models


class RemoveAdminDefaultMessageMixin:

    def remove_default_message(self, request):
        storage = messages.get_messages(request)
        try:
            del storage._queued_messages[-1]
        except KeyError:
            pass
        return True

    def response_add(self, request, obj, post_url_continue=None):
        """override"""
        response = super().response_add(request, obj, post_url_continue)
        self.remove_default_message(request)
        return response

    def response_change(self, request, obj):
        """override"""
        response = super().response_change(request, obj)
        self.remove_default_message(request)
        return response

    def response_delete(self, request, obj_display, obj_id):
        """override"""
        response = super().response_delete(request, obj_display, obj_id)
        self.remove_default_message(request)
        return response


class MessageAdmin(RemoveAdminDefaultMessageMixin, admin.ModelAdmin):

    def save_model(self, request, obj, form, change):
        self.message_user(request, 'save success!')
        return super().save_model(request, obj, form, change)


admin.site.register(models.Message, MessageAdmin)

这不是最优雅的解决方案，但是您始终可以覆盖response_add类的response_change和ModelAdmin方法，删除self.message_user调用，如果不这样做，不想让您的admin.py文件上的所有内容混乱，您只需在帮助程序文件中创建SilentModelAdmin，即可覆盖这些方法并删除您不想显示的消息。
