Dropzone没有绑定到模型

标签: asp.net asp.net-mvc dropzone.js

我正在使用dropzone.js以包含其他字段的形式上传文件。

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()

    @Html.DropDownListFor(x => x.installation, Model.installationList, new { data_placeholder = "Select one item please" })
    @Html.ValidationMessageFor(model => model.installation, "", new { @class = "text-danger" })

<div id="files" name="files" class="dropzone"></div>

<input type="submit" value="@Resources.Global.Save" class="btn btn-default" />
}

JS:

Dropzone.options.files = {
            autoProcessQueue: false,
            uploadMultiple: true,
            parallelUploads: 100,
            maxFiles: 100,

            paramName: "files", // The name that will be used to transfer the file
            maxFilesize: 8, // MB
            url: "/ActionPlan/Home/Create"  // Same as URL generated from the form
        };

我的模特:

        // installation 
        [Display(Name = "Anomaly_Installation", ResourceType = typeof(Resources.ActionPlan))]
        public int installation { get; set; }
        public IEnumerable<SelectListItem> installationList { get; set; }

// files uploaded
        public HttpPostedFileBase[] files { get; set; }

当我提交表单时,没有文件附加到模型,但来自位置的数据是否正常,为什么?如何解决这个问题?

编辑:我做了一些更改,但同样的问题:

HTML(Razor)

@using (Html.BeginForm("Create", "Home", FormMethod.Post, new { enctype = "multipart/form-data", @class = "dropzone", id = "myForm" }))

我补充道:

<div class="dropzone-previews"></div>
                <div class="fallback">
                    <!-- this is the fallback if JS isn't working -->
                    <input name="files" type="file" multiple />
                </div>

JS

Dropzone.options.files = {
            autoProcessQueue: false,
            uploadMultiple: true,
            parallelUploads: 25,
            maxFiles: 25
        };

当我检查发送的标题时,我没有看到任何文件(这是整个表单):

最终解决方案: HTML:

@using (Html.BeginForm("Create", "Home", FormMethod.Post, new { enctype = "multipart/form-data", @class = "dropzone", id = "myForm" }))
{
...
<div class="fallback">
                    <!-- this is the fallback if JS isn't working -->
                    <input name="files" type="file" multiple />
                </div>
}

JS:     Dropzone.autoDiscover = false;

        var myDropzone = new Dropzone('#myForm', {
            paramName: 'files',
            autoProcessQueue: false,
            uploadMultiple: true,
            parallelUploads: 25,
            maxFiles: 25
        });

        $("form").on("submit", function (event) {
            myDropzone.processQueue(); // Tell Dropzone to process all queued files.
        });

这是我的模特:

public HttpPostedFileBase[] files { get; set; }

我猜你指定的选项永远不会被应用。这可以解释为什么一旦提交表单就没有文件附加到您的模型,因为它们已经在上传时处理过。 要正确应用所需的选项,您需要关闭Dropzone中的auto discovery function

Dropzone.autoDiscover = false;

那样你必须programmatically initialize Dropzone:

var myDropzone = new Dropzone('form', {
    paramName: 'files',
    autoProcessQueue: false,
    uploadMultiple: true,
    parallelUploads: 25,
    maxFiles: 1
});

Demo

autoProcessQueue

  

设置为false时,您必须自己调用myDropzone.processQueue()才能上传删除的文件。有关处理队列的更多信息,请参见下文。

1)在浏览器中打开工具开发控制台,并在&#34; dropzone.uploadFile&#34;中放置一个断点。 (见图片:http://www.tiikoni.com/tis/view/?id=033ad74) 2)删除图像,检查文件是否为空

如果为空,则错误可能在后端脚本中(通常是php,asp,ecc中的控制器)。 如果不为空,请测试一个干净的dropzone版本(http://www.dropzonejs.com/)并查看差异。

对不起我可怕的英语:)
