xadmin 自定义actions

1.编写actions

from xadmin.plugins.actions import BaseActionView
from django.contrib import messages

class ClaimAction(BaseActionView):
    '''
    批量认领功能
    '''
    # 这里需要填写三个属性
    action_name = "claim"  #: 相当于这个 Action 的唯一标示, 尽量用比较针对性的名字
    description = _(u'收养选中的商品')  #: 描述, 出现在 Action 菜单中, 可以使用 ``%(verbose_name_plural)s`` 代替 Model 的名字.
    icon = 'fa fa-tasks'  # 图标
    model_perm = 'change'  #: 该 Action 所需权限

    # 而后实现 do_action 方法
    def do_action(self, queryset):
        # queryset 是包含了已经选择的数据的 queryset
        queryset.update(belonger=self.request.user)

        messages.success(self.request, '认领成功')
        # 返回 HttpResponse
        return redirect(self.request.get_full_path())

2.引用

from erp.xadminconf.myaction import ClaimAction

class ClaimGoodsAdmin(GoodsInfoModelAdmin):
    # reversion_enable = True
    actions = (ClaimAction,)

3.xadmin会默认引用父类的actions，如果不需要可以通过修改源码解决

# 路径 xadminpluginsactions.py

# 大概在236行
    def get_actions(self):
        if self.actions is None:
            return OrderedDict()

        actions = [self.get_action(action) for action in self.global_actions]
        
        # for klass in self.admin_view.__class__.mro()[::-1]: # 注释掉这一句
        for klass in (self.admin_view,): # 改成这一句
            class_actions = getattr(klass, 'actions', [])

            if not class_actions:
                continue
            actions.extend(
                [self.get_action(action) for action in class_actions])

        # get_action might have returned None, so filter any of those out.
        actions = filter(None, actions)
        if six.PY3:
            actions = list(actions)

        # Convert the actions into a OrderedDict keyed by name.
        actions = OrderedDict([
            (name, (ac, name, desc, icon))
            for ac, name, desc, icon in actions
        ])

        return actions
