如何使用Knockout.Js将我的模型发布到Odata Web Api

问题描述

嗨

我正在尝试将模型发布到web api，每次只有一个项目出现在post方法中。就像我发布一个名为Movie的模型，Id和Title是这个模型的属性。

所以我的问题是当我试图使用knockout.js从客户端发布它时，只有标题值才会出现在web api post方法中。





在api中发布方法

Hi
i'm trying to post model to a web api where every time only one item in the model shown up at post method. like if i'm posting a model called Movie ,Id and Title are the properties of this model.
so here my problem is when i'm trying to post it from client side using knockout.js,only Title value is coming in the web api post method.


post method in api

[HttpPost]
        [ODataRoute("CreateMovie")]
        public IHttpActionResult CreateMovie(Movie parameters)
        {
            if (!ModelState.IsValid)
            {
                return BadRequest(ModelState);
            }

            string title = "Test";//parameters["Title"] as string;

            Movie movie = new Movie()
            {
                Title = title,
                ID = _db.Movies.Count + 1,
            };

            _db.Movies.Add(movie);

            return Created(movie);
        }

客户端代码：

client side code:

window.viewModel = (function () {
    var self = this;

    self.movies = ko.observableArray();
    self.id = ko.observable();
    self.title = ko.observable();
    self.year = ko.observable();
    self.duedate = ko.observable();
    self.ischeckedout = ko.observable();
    self.errorMessage = ko.observable();

    // Function to invoke the non-bindable "CreateMovie" action.
    self.createMovie = function () {
        var movieVal = { ID: self.id(), Title: self.title(), Year: self.year(), DueDate: null, IsCheckedOut: self.ischeckedout() };
        ajaxRequest("post", "odata/CreateMovie",movieVal)
            .done(function (result) {
                self.movies.push(new movie(result))
            })
            .fail(function (jqXHR, textStatus, errorThrown) {
                self.errorMessage(errorThrown);
            });
    }    // Ajax helper
    function ajaxRequest(type, url, data) {
        debugger;
        var options = {
            dataType: "json",
            contentType: "application/json",
            type: type,
            data: data ? ko.toJSON(data) : null
        };
        self.errorMessage(null); // clear error message
        return $.ajax(url, options);
    }
})();

$(document).ready(function () {
    ko.applyBindings(viewModel);
});

所以在web api中post methdo only标题每次都出现并非所有其他项目。
