我對MEAN堆棧相當陌生,在學習本教程之後:http://www.bradoncode.com/tutorials/mean-stack-tutorial-part-4-angularjs/,我試圖製作自己的Web應用程序來發送和接收發票。我有一個localhost:3000/invoices頁面,它目前是空的([])。我正在嘗試填寫表單併發布到localhost:3000/invoices,以便填充MongoDB數據庫。我的MongoDB進程正在不斷運行。這是模型概述我需要在記錄的所有字段:MEAN:在開機自檢後出現錯誤400(錯誤的請求)
'use strict';
/**
* Module dependencies.
*/
var mongoose = require('mongoose'),
Schema = mongoose.Schema,
validation = require('./validation.server.model');
/**
* Invoices Schema
*/
var InvoiceSchema = new Schema({
invoice_date: {
type: Date,
default: Date.now
},
from_entity: {
type: String,
default: '',
trim: true,
required: 'legal entity cannot be blank'
},
from_service: {
type: String,
default: '',
trim: true,
required: 'service line cannot be blank'
},
country: {
type: String,
default: '',
trim: true,
required: 'country cannot be blank'
},
to_entity: {
type: String,

trim: true,
required: 'legal entity cannot be blank'
},
to_service: {
type: String,
default: '',
trim: true,
required: 'service line cannot be blank'
},
partner: {

amount: {

mongoose.model('Invoice', InvoiceSchema);
這是我的發票客戶端控制器:
'use strict';
// Invoices controller
angular.module('invoices').controller('InvoicesController', ['$scope', '$stateParams', '$location', 'Authentication', 'Invoices', '$filter',
function($scope, $stateParams, $location, Authentication, Invoices, $filter) {
$scope.authentication = Authentication;
$scope.currentPage = 1;
$scope.pageSize = 10;
$scope.offset = 0;
// Page changed handler
$scope.pageChanged = function() {
$scope.offset = ($scope.currentPage - 1) * $scope.pageSize;
};
// Create new Invoice
$scope.create = function() {
var invoice = new Invoices ({
amount: this.amount,
invoice_number: this.invoice_number,
partner: this.partner,
to_service: this.to_service,
to_entity: this.to_entity,
country: this.country,
from_service: this.from_service,
from_entity: this.from_entity
});
// Redirect after save
invoice.$save(function(response) {
$location.path('invoices/' + response._id);
// Clear form fields
$scope.name = '';
}, function(errorResponse) {
$scope.error = errorResponse.data.message;
});
};
// Remove existing Invoice
$scope.remove = function(invoice) {
if (invoice) {
invoice.$remove();
for (var i in $scope.invoices) {
if ($scope.invoices [i] === invoice) {
$scope.invoices.splice(i, 1);
}
}
} else {
$scope.invoice.$remove(function() {
$location.path('invoices');
});
}
};
// Update existing Invoice
$scope.update = function() {
var invoice = $scope.invoice;
invoice.$update(function() {
$location.path('invoices/' + invoice._id);
}, function(errorResponse) {
$scope.error = errorResponse.data.message;
});
};
// Find a list of Invoices
$scope.find = function() {
$scope.invoices = Invoices.query();
};
// Find existing Invoice
$scope.findOne = function() {
$scope.invoice = Invoices.get({
invoiceId: $stateParams.invoiceId
});
};
// Search for a Invoice
$scope.invoiceSearch = function(invoice) {
$location.path('invoices/' + invoice._id);
};
}
]);
而且這是在前端AngularJS一個簡單的表格:
<section data-ng-controller="InvoicesController">

當我開始並提交表單我得到如下:
金額是通過模型顯而易見的必填字段,我總是肯定會填寫該值。我總是輸入數字和小數,但是表示該字段是必需的,並顯示錯誤的請求。此外,每當我做npm開始,我的應用程序加載沒有任何錯誤。我曾試圖觀看過幾個YouTube教程,但沒有一個澄清了這個不起作用的原因。 Swift幫助將不勝感激:)
編輯:當我從模型中刪除所需的,交易通過,但沒有輸入到表格中的值都記錄下來,只有發票日期是。
我通過刪除發票得到它的工作。在「data-ng-model =」invoice.currency「」中。你的方法更好嗎? – Shashank
