如何在mongoose中关联数据模式

I'm trying to associate 2 schema on nodejs/mongoose app. my first model:

我正在尝试在nodejs / mongoose app上关联2个架构。我的第一个模特：

var mongoose = require("mongoose");
var projectSchema = new Schema({
  pname: String,
  pnumber: String,
  plocation: String,
  pclient: String,
  clientabn: String,
  contname: String,
  contnumber: String,
  mobile: String,
  address: String,
  city: String,
  country: String,
  boqs: [{
    type: mongoose.Schema.Types.ObjectId,
    ref: "Boq",
  }]
});

module.exports = mongoose.model("Project", projectSchema);

second model:

第二种模式：

var mongoose = require("mongoose");
var boqSchema = new Schema({
    boqDesc: String,
    boqUnit: String,
    boqQty: String,
    boqRate: String,
    boqPrice: String,

});

module.exports = mongoose.model("Boq", boqSchema);

And this is my post rout:

这是我的帖子溃败：

app.post("/myprojects/:id/boq", function(req, res) {
  Project.findById(req.params.id, function(err, project) {
    if (err) {
      console.log(err);
    } else {
      Boq.create(req.body.boq, function(err, boq) {
        if (err) {
          console.log(err);
        } else {
          project.boqs.push(boq);
          project.save();
          res.redirect("/myprojects/" + project._id + "/boq");
          console.log(boq);
        }
      });
    }
  });
});

When is posting, only an id of boq will be saved on database not any data from boq's form. anyone knows what is wrong with this code? output of console.log: console.log output

发布时，只有boq的id将保存在数据库中而不是来自boq表单的任何数据。谁都知道这段代码有什么问题？ console.log的输出：console.log输出

console.log(project)

执行console.log（项目）

Below is the post form:

以下是帖子表格：

<form action="/myprojects/<%= project._id %>/boq" method="POST">
   <table class="table" id="toptab">
      <tbody>
         <tr>
            <td class="td6"><b>No.</b></td>
            <td class="td7"><b>Item Description/Scope of Work</b></td>
            <td class="td8"><b>Unit</b></td>
            <td class="td9"><b>Quantity</b></td>
            <td class="td10"><b>Rate</b></td>
            <td class="td11"><b>Price</b></td>
         </tr>
         <tr>
            <td class="td6"></td>
            <td class="td7" contenteditable="true" name="boq[boqDesc]"></td>
            <td class="td8" contenteditable="true" name="boq[boqUnit]"></td>
            <td class="td9" contenteditable="true" name="boq[boqQty]"></td>
            <td class="td10" contenteditable="true" name="boq[boqRate]">$</td>
            <td class="td11" contenteditable="true" name="boq[boqPrice]"></td>
         </tr>
      </tbody>
   </table>
   <button type="submit" name="submit" class="btn btn-primary">Save</button>
</form>

1 个解决方案

#1

you're calling Boq.create(undefined, callback);

你正在调用Boq.create（undefined，callback）;

this creates a boq document in db with no fields (except the _id).

这会在db中创建一个没有字段的boq文档（除了_id）。

it passes validation because all boq's fields are not required.

它通过验证，因为不需要所有boq的字段。

go to your client, and make sure you're adding boq data to http request's body correctly.

转到您的客户端，并确保您正确地将boq数据添加到http请求的正文。

add <input> elements in between <td></td> tags, each named after one of the fields in boq's schema. for instance <td><input type="text" name="boqDesc"></td>

在标记之间添加元素，每个标记都以boq架构中的一个字段命名。例如
