根据数据库属性动态地从req.body中选取值

ejs express node.js javascript

我正在构建一个应用程序usine node/ejs/mongo,在这里用户正在构建一个功能调查,需要为每个问题设置所需的级别。他们用来选择级别的表单有一系列的选择,如下所示:

<select class="form-control col-sm-4" id="<%=capability.capabilityId%>" name="<%=capability.capabilityId%>">
   <option value=1>Developing</option>
   <option value=2>Intermediate</option>
   <option value=3>Advanced</option>
   <option value=4>Role Model</option>
</select>

当用户提交此表单时,我希望更新评估以加载到这些预期级别。

我的MongoDB中的评估模式如下:

var assessmentSchema = new mongoose.Schema ({
  title: String,
  startDate: Date,
  endDate: Date,
  behaviours: [{
    behaviourName: String,
    behaviourId: String,
    order: Number,
    capabilities: [{
      orderCap: Number,
      capabilityId: String,
      capabilityName: String,
      capabilityDesc: String,
      developing: String,
      intermediate: String,
      advanced: String,
      roleModel: String,
      expectedLevel: Number,
      motivation1: String,
      motivation2: String,
      motivation3: String,
      motivation4: String,
      motivation5: String
    }]   //capabilities object
  }],
  targetEmployees:[{
    type: mongoose.Schema.Types.ObjectId,
    ref: "Users"
  }]  //behaviours object
});

我想的是,我要循环使用所有功能,找到 req.body 有一个匹配的名字 capabilityId ,然后更新 desiredLevel . 我就是不知道该怎么做。我的路线代码当前如下:

router.put(':id/levels', function(req, res) {
  Assessment.findById(req.params.id, function(err, foundAssessment) {
    foundAssessment.behaviours.forEach(function(b) {
      b.capabilities.forEach(function(c) {
        c.expectedLevel = req.body.SOMETHINGHERE
      });
    });

    foundAssessment.save(function(err) {
      if (err) {
        console.log(err);
        req.flash("error", err.message);
        res.redirect("back");
      } else {
        // Send json back to xhr request
        res.json(foundAssessment);
      }
    });
  });
});
