保存模型时超出了最大递归深度

Question

我有几个ModelAdmin类，我想在保存模型时执行相同的操作，所以我为此创建了mixin对象：

class SaveModelMixin(object):
    def save_model(self, request, obj, form, change):
        if obj.is_executed and 'is_executed' in obj.changed_data:
            obj.date_execution = datetime.date.today()
        super(self.__class__, self).save_model(request, obj, form, change)

当我尝试在admin中保存对象时，此方法只是一次又一次地运行，我无法弄清楚原因。

看起来您的super()来电不正确，请尝试以下操作：

super(SaveModelMixin, self).save_model(request, obj, form, change)

请参阅此处的说明：How to avoid infinite recursion with super()?
