【中文标题】如何使用 AngularJS(Django 框架)将值保存到数据库【英文标题】:How to save values to database using AngularJS (Django Frame Work) 【发布时间】:2015-12-10 01:25:03 【问题描述】:您好,我的项目使用 AngularJS 在 Django 框架上运行。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:

【问题讨论】:
从正确创建表单开始。建议你学习一些基本的表单教程,包括使用 django 后端。问题太宽泛,您需要将问题范围缩小到更具体的问题 嗨 Charlietfl,我没有在这里使用 django-forms。只是 AngJS 和视图 没关系...表单无法如图所示工作,它是无效的 html 并且不包含用户输入元素 【参考方案1】:如果您不想使用表单,可以使用 AJAX。在 AngularJS 中,它看起来像这样。请注意,您的控制器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 指向一个视图,该视图会将其保存在数据库中。希望这会有所帮助。
【讨论】:
你提到的project_id到底是什么? 只是一个变量名,想展示如何将变量值传递给数据以上是关于如何使用 AngularJS(Django 框架)将值保存到数据库的主要内容,如果未能解决你的问题,请参考以下文章
