[英]Get values from Javascript object in Rails controller
I'm fairly new to Rails but I have a situation where a user can create a vacancy and select modules for that vacancy by dragging en dropping modules.我对 Rails 还很陌生,但我有一种情况,用户可以通过拖放模块来创建一个空缺并为该空缺选择模块。 Everytime something has changed (a module has been added/removes to the vacancy of the order has changed) I send a javascript object to the rails controller through AJAX and I want to extract the values from this object and story them in my DB.
每次发生变化时(一个模块已添加/删除到订单的空缺已更改)我通过 AJAX 向 rails 控制器发送一个 javascript 对象,我想从这个对象中提取值并将它们记录在我的数据库中。
My object will look like this:我的对象将如下所示:
addedModules = {
module: [
{module_id: '1', name: 'first-module', width: '3', height: '1', position: '1'},
{module_id: '5', name: 'fifth-module', width: '1', height: '1', position: '2'},
{module_id: '3', name: 'third-module', width: '4', height: '1', position: '3'},
]
};
In my controller I would like to go through every module and extract their module_id, name, etc.在我的控制器中,我想遍历每个模块并提取它们的 module_id、名称等。
AJAX block: AJAX 块:
$.ajax({
type: "POST",
url: "../../../vacancies/" + <%= params[:vacancy_id] %> + "/update_with_modules",
data: "addedModules=" + addedModules
}).done(function (response) {
console.log(response);
});
Is there a way to do so or is there a better solution?有没有办法这样做或者有更好的解决方案?
Change this line:改变这一行:
data: "addedModules=" + addedModules
by this line:通过这一行:
data: {addedModules: addedModules}
