Xadmin+rules实现多选行权限方式(级联效果)
行权限配置
xadmin中配置且不需要数据库支持,
安装并配置rules
pip安装:
pip install rules
配置settings.py
# settings.py INSTALLED_APPS = ( # ... 'rules', ) AUTHENTICATION_BACKENDS = ( 'rules.permissions.ObjectPermissionBackend', 'django.contrib.auth.backends.ModelBackend', )
配置models.py
# models.py class CompanyUser(models.Model): users = models.OneToOneField(User, verbose_name='用户名', on_delete=User) is_admin = models.BooleanField('是否运营人员', default=False) category_code = models.ManyToManyField(user, verbose_name='可管理', max_length=20, blank=True, default='') #ForeignKey为单选,ManyToManyField为多选. def __str__(self): return str(self.users) class Meta: verbose_name = '管理账号' verbose_name_plural = verbose_name class user(models.Model): title = models.CharField(max_length=50, verbose_name="文章标题") author = models.CharField(max_length=50, null=True, blank=True, verbose_name='文章作者') #category = models.ForeignKey(Category, verbose_name="所属类别", null=True, blank=True, on_delete=Category)(多选时启用) content = UEditorField(verbose_name="文章内容", imagePath='static/img/', filePath="static/img/", upload_settings={"imageMaxSize": 1204000}, default='') click_num = models.IntegerField(default=0, verbose_name="浏览量", ) image = models.FileField(max_length=200, verbose_name="文章图片", null=True, blank=True, upload_to='static/img', default=None) add_time = models.DateField(default=datetime.now, verbose_name="添加时间") def __str__(self): return self.title class Meta: verbose_name = '文章信息' verbose_name_plural = verbose_name
使用rule
在models的同级目录新增rules.py,配置该app相关的对象权限
# rules.py #必须将以下内容添加到rules.py文件的顶部,否则在尝试导入django-rules本身时会出现导入错误。 from __future__ import absolute_import import rules # 使用修饰符@rules.predicate自定义predicates(判断),返回True表示有权限,False表示无权限 @rules.predicate def is_colleague(user, entry): if not entry or not hasattr(user, 'companyuser'): return False return entry.category_code == user.companyuser.category_code @rules.predicate def is_admin(user): if not hasattr(user, 'companyuser'): return False return user.companyuser.is_admin is_admins = is_admin | rules.is_superuser | is_colleague # 设置Rules rules.add_rule('can_view_user', is_admins) rules.add_rule('can_delete_user', is_admins) rules.add_perm('can_change_user', is_admins) # 设置Permissions rules.add_perm('data_import.view_user', is_admins) rules.add_perm('data_import.delete_user', is_admins) rules.add_perm('data_import.add_user', is_admins) rules.add_perm('data_import.change_user', is_admins)
adminx.py设置
必须引用rules文件,权限规则才会生效,对于xadmin,添加from .rules import *即可.
# adminx.py from __future__ import absolute_import import xadmin from xadmin import views from lice.models import * from .rules import * class UserAdmin(object): list_display = 'title', search_fields = 'title', 'content', list_filter = 'category', readonly_fields = 'click_num', exclude = 'add_time', style_fields = {"content": "ueditor"} def queryset(self): qs = super(UserAdmin, self).queryset() if self.request.user.is_superuser or is_admin(self.request.user): return qs try: print('-------------------') print(qs)#打印一下qs的结果 print('-------------------') print(CompanyUser.objects.get(users=self.request.user).category_code.filter()) #打印登录账号的可管理内容 print('-------------------') return CompanyUser.objects.get(users=self.request.user).category_code.filter() except AttributeError: return None class CompanyUserAdmin(object): pass xadmin.site.register(CompanyUser, CompanyUserAdmin) xadmin.site.register(user, UserAdmin)
效果展示:
需先在管理账号里为账号添加可管理内容
大功告成~
行权限配置(多选)
若要达到级联多选效果需要在原基础上修改models.py并添加 views.py\urls.py及js即可实现
新建一个类别模型(可对比上面的模型),并在已有的CompanyUser中添加类别字段
models.py
# models.py class CompanyUser(models.Model): users = models.OneToOneField(User, verbose_name='用户名', on_delete=User) is_admin = models.BooleanField('是否运营人员', default=False) category = models.ForeignKey(Category, on_delete=Category, verbose_name='可管理分类', max_length=20, null=True, blank=True, default='') category_code = models.ManyToManyField(user, verbose_name='可管理文章', max_length=20, null=True, blank=True, default='') #ForeignKey为单选,ManyToManyField为多选. def __str__(self): return str(self.users) class Meta: verbose_name = '管理账号' verbose_name_plural = verbose_name class Category(models.Model): name = models.CharField(max_length=20, verbose_name="文章类别") add_time = models.DateField(default=datetime.now, verbose_name="添加时间") def __str__(self): return self.name class Meta: verbose_name = "类别信息" verbose_name_plural = verbose_name
F12找到一级目录和二级目录的select中ID
我的一级目录id=id_category,二级目录id=id_category_code
下面开始创建一个新的js文件
并将id替换到js文件中
#名字随便.我的是xadmin.js # xadmin.js $('#id_category').change(function () { var module = $('#id_category').find('option:selected').val(); //获取父级选中值 $('#id_category_code')[0].selectize.clearOptions();// 清空子级 if (module) $.ajax({ type: 'get', url: '/select/one_two/?module=' + module, data: '', async: true, beforeSend: function (xhr, settings) { xhr.setRequestHeader('X-CSRFToken', '{{ csrf_token }}') }, success: function (data) { data = JSON.parse(data.data)//将JSON转换 console.log(data); for (var i = 0; i < data.length; i++) { var test = {text: data[i].fields.title, value: data[i].pk, $order: i + 1}; //遍历数据,拼凑出selectize需要的格式 $('#id_category_code')[0].selectize.addOption(test); //添加数据 } }, }) else { #如果一级目录为分配则遍历所有子目录可选项 $.ajax({ type: 'get', url: '/select/one_two/?module=all', data: '', async: true, beforeSend: function (xhr, settings) { xhr.setRequestHeader('X-CSRFToken', '{{ csrf_token }}') }, success: function (data) { data = JSON.parse(data.data)//将JSON转换 console.log(data); for (var i = 0; i < data.length; i++) { var test = {text: data[i].fields.title, value: data[i].pk, $order: i + 1}; //遍历数据,拼凑出selectize需要的格式 $('#id_category_code')[0].selectize.addOption(test); //添加数据 } }, }) } })
将js中此行的 ‘title' 替换为你想要显示的数据库字段名 有两个(20行|40行)
var test = {text: data[i].fields.title, value: data[i].pk, $order: i + 1}; //遍历数据,拼凑出selectize需要的格式
将写好的js文件放入xadmin\static\xadmin\js中,如图所示
找到xadmin\widgets.py,将js添加进去(这是xadmin的搜索类)
添加视图
view.py
#导入serializers from django.core import serializers from django.contrib.auth.mixins import LoginRequiredMixin from django.views import View # 二级联动View函数 class SelectView(LoginRequiredMixin, View): def get(self, request): # 通过get得到父级选择项 id_category = request.GET.get('module', '') # 筛选出符合父级要求的所有子级,因为输出的是一个集合,需要将数据序列化 serializers.serialize() if id_category == 'all': id_category_code = serializers.serialize("json", user.objects.all())s #通过Ajax请求查询 else: id_category_code = serializers.serialize("json", user.objects.filter(category=int(id_category))) # 判断是否存在,输出 if id_category_code: return JsonResponse({'data': id_category_code})
url.py
from users.views import SelectView
url(r'^select/one_two/', SelectView.as_view(), name='one_two'),
效果展示:
操作方法同上
完成!
