如图红框增加操作

将以下代码添加到HeroAdmin类中

actions = ["mark_immortal"]
def mark_immortal(self, request, queryset):
    queryset.update(is_immortal=True)

修改后完整代码如下：

@admin.register(Hero)
class HeroAdmin(admin.ModelAdmin):
    list_display = ("name", "is_immortal", "category", "origin", "is_very_benevolent")
    list_filter = ("is_immortal", "category", "origin", IsVeryBenevolentFilter)
    def is_very_benevolent(self, obj):
        return obj.benevolence_factor > 75
    is_very_benevolent.boolean = True
    
    actions = ["mark_immortal"]
    
    def mark_immortal(self, request, queryset):
        queryset.update(is_immortal=True)

显示效果如下：
