創建於貓鼬

Question

嵌套模式假設我有這樣的貓鼬架構在我models.js文件：

var Mongoose = require('mongoose'); 

var ProjectSchema = new Mongoose.Schema({ 
    "name": String, 
    "id": String, 
    "phone": String, 
    "address": String, 
    "dob": String, 
    "action": String, 
    "ccard": { 
     "type": String, 
     "number": String, 
     "status": String, 
     "expiry": String 
    } 
}); 

exports.Project = Mongoose.model('Project', ProjectSchema); 

並假設我已經有網站使用的MongoDB從與必要信息的JSON文件加載數據。我將如何在HTML模板中調用ccard的字段？截至目前，我可以在{{each projects}} ... {{/each}}條款中撥打{{name}}和{{id}}，但沒有問題，但是當我撥打{{ccard.number}}時，它不會輸出任何內容。

HTML樣本：

{{each projects}} 
<table> 
    <tr> 
     <td>{{ccard.type}}</td> 
     <td>{{ccard.number}}</td> 
     <td>{{ccard.status}}</td> 
     <td>{{ccard.expiry}}</td>             
    </tr> 
</table> 
{{/each}} 

在模式或模板變量或其他地方的問題？

Answer 1

var Mongoose = require('mongoose'); 

var ProjectSchema = new Mongoose.Schema({ 
    "name": String, 
    "id": String, 
    "phone": String, 
    "address": String, 
    "dob": String, 
    "action": String, 
    "ccard": { 
     "type": { 
      "type": String, 
     } 
     "number": String, 
     "status": String, 
     "expiry": String 
    } 
}); 

exports.Project = Mongoose.model('Project', ProjectSchema); 

我不知道上面的代碼是否正常工作。如果它不更改列名稱，如下所述。

var Mongoose = require('mongoose'); 

var ProjectSchema = new Mongoose.Schema({ 
    "name": String, 
    "id": String, 
    "phone": String, 
    "address": String, 
    "dob": String, 
    "action": String, 
    "ccard": { 
     "ccartType": String, 
     "number": String, 
     "status": String, 
     "expiry": String 
    } 
}); 

exports.Project = Mongoose.model('Project', ProjectSchema); 

模板代碼

{{each projects}} 
<table> 
    <tr> 
     <td>{{ccard.ccartType}}</td> 
     <td>{{ccard.number}}</td> 
     <td>{{ccard.status}}</td> 
     <td>{{ccard.expiry}}</td>             
    </tr> 
</table> 
{{/each}} 

變化如上所述，並確保該模型是在MongoDB的架構改變了模型。

原因可能是它正在ccard爲單柱type：string

Answer 2

架構寫入正確。 我可以看到

"ccard": { 
     "type": String, 
     "number": String, 
     "status": String, 
     "expiry": String 
} 

您可以通過保存文檔的變量名來訪問。讓我們假設你在

var = project 

進賬1號文件，現在你可以訪問#{project.ccard.status}或{{project.ccard.status}}
