javascript - 如何使用 AngularJS (Django Frame Work) 将值保存到数据库

Question

您好，我的项目在 Django 框架上工作，并使用了一些 AngularJS。我需要实现的是当我点击我的页面(html)上的提交时，它应该保存我输入到数据库中的所有值。我听说我只需要一个简单的提交按钮，主要更改在 views.py 中。我对 Django 和 AngularJS 都很陌生。以下是我的代码。提前致谢。

HTML 和 AngularJS:

{% extends "base.html" %}
{% load static %}
{% block stylesheets %}
<link href="{% static 'css/xxg.css' %}" rel="stylesheet">


{% endblock %}

{% block mainbody %}

        <div class="well" ng-controller="LayerCtrl">

如果您不想使用表单，则可以使用 AJAX。在 AngularJS 中，它看起来像这样。请注意，您的 Controller 应该具有所需的参数:

$scope.addsomething = function() {
      token = $window.localStorage.token;
      //data to be submitted 
      $scope.data = {"name": $scope.name,"project": project_id,"some_url": someURL,"status": "1","type": 1};
      $http.defaults.headers.common.Authorization = 'token '+$window.localStorage.token;
      req = $http({
            method: "POST",
            url:"your_url/",
            data:$scope.data,
            headers: {
                'Content-Type': 'application/json'
            },
      });
      req.success(function(data,status) {
         //do something on success
      });
      req.error(function(data, status, headers, config) {
        //do something on error
      });
    }

在您的后端，您只需将此 URL 指向一个 View ，该 View 将把它保存在数据库中。希望这会有所帮助。
