如何使用 CASL/能力处理猫鼬上的条件

编程问答 2022-05-22

问题描述

描述错误 我有一个带有引用另一个集合模型的字段的猫鼬模型，但是当我定义使用条件字段的条件时，它会忽略条件并且不会在定义的能力中执行条件。 复制

// ROLES MODEL
const mongoose = require("mongoose");

const { Schema } = mongoose;

const RoleSchema = Schema({
  organization: { type: Schema.Types.ObjectId,ref: "organization",required: true },role: {
    type: String,required: true,lowercase: true
  },// [learners,moderators,facilitators,learnerkia staffs etc]
  dateCreated: { type: Date,default: Date.Now }
});

// exports the schema
module.exports = mongoose.model("role",RoleSchema);

// ORGANIZATION MODEL
const mongoose = require("mongoose");
const { accessibleRecordsPlugin } = require("@casl/mongoose");

const { Schema } = mongoose;

const OrganizationSchema = new Schema({
  orgName: {
    type: String,required: false,unique: true,email: { type: String,trim: true,unique: true },phone: { type: String,password: { type: String,firstName: { type: String,lowercase: true },lastName: { type: String,slug: { type: String,required: false },customerId: { type: String,profilelogo: { type: String,industry: { type: Schema.Types.ObjectId,ref: "industry",isAdmin: { type: String,default: true },dateCreated: { type: Date,default: Date.Now },active: { type: Boolean,default: false },updateHistory: [{
    userId: String,date: String
  }]
});

OrganizationSchema.plugin(accessibleRecordsPlugin);

module.exports = mongoose.model("organization",OrganizationSchema);

// PERMISSION ON ROLE
exports.defineAbilitiesOnRolesFor = (user) => {
  const { can,rules } = new AbilityBuilder(Ability);
  if (user.isAdmin) {
    can(
      "mange","Role",{ organization: user._id } // manage your own account roles
    );
  }




// PERMISSION CHECKER

async function permissionChecker(model,defineAbilitiesOnSubjectFor,userId,action,subject) {
  try {
    // get user and all attributes
    const user = await model.findOne({ _id: userId });

    // get ability
    const ability = defineAbilitiesOnSubjectFor(user);

    // get permission
    const permission = ability.can(action,subject);

    // console.log(permission);
    return permission;
  } catch (error) {
    // console.log(error);
    return false;
  }
}

module.exports = {
  permissionChecker
};

// SERVICE FILE
const Role = require("../models/role");
const { permissionChecker } = require("../helpers/permissionHelpers");
const action = "read";
const subject = ROLE
const loggedInUser = res.locals.user.userId
const Organizations = require("../models/organization");


    const permission = await permissionChecker(
      Organizations,defineAbilitiesOnRolesFor,loggedInUser,subject
    );
    if (permission) {
      await Role.find({ organization: orgId },{ __v: 0 })
        .populate("organization","orgName")
        .then((response) => res.status(200).json({
          status: true,message: "successfully retrieved all roles created for this organization",data: response,errors: []
        }))
        .catch((err) => {
          res.status(500).json({
            status: false,message: "internal server error",data: null,errors: [err]
          });
        });
      return;
    }

预期行为 在为 ROLE 能力设置条件后，组织管理员应该只能管理属于他的组织而不是其他组织的角色，因为他不拥有这些角色。但现在条件失败或没有被 casl 读取，任何管理员都可以管理属于任何组织的任何角色，这是意料之外的。请帮忙？我的代码有问题吗？ CASL V4
