删除Django admin中的默认删除操作

Question

如何删除Django管理员中的默认删除操作？以下工作会怎样？

actions = [ ] 

Answer 1

这有效:

def get_actions(self, request):
    actions = super().get_actions(request)
    if 'delete_selected' in actions:
        del actions['delete_selected']
    return actions

这也是基于以下Django文档执行此操作的推荐方法:

有条件地启用或禁用操作

Answer 2

在您的管理类中,定义has_delete_permission返回False:

class YourModelAdmin(admin.ModelAdmin):
    ...

    def has_delete_permission(self, request, obj=None):
        return False

然后,它不会显示删除按钮,也不允许您删除管理界面中的对象.

Answer 3

您可以在网站范围内停用"删除所选"操作:

from django.contrib.admin import site
site.disable_action('delete_selected')

当您需要包含此操作时,请添加'delete_selected'到操作列表:

actions = ['delete_selected']

Answer 4

如果要删除所有操作:

class UserAdmin(admin.ModelAdmin):
    model = User
    actions = None

如果您想要一些特定的动作:

class UserAdmin(admin.ModelAdmin):
    model = User
    actions = ['name_of_action_you_want_to_keep']
