asp.net – Dropzone没有绑定到模型

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
        };

我的型号：

// 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,但位置的数据是可以的,为什么？如何解决这个问题？

编辑：我做了一些修改,但同样的问题：

HTML(Razor)

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

我补充说：

<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,parallelUploads: 25,maxFiles: 25
        };

当我检查头文件发送时,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",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,maxFiles: 25
        });

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

为了这个我的模型：

public HttpPostedFileBase[] files { get; set; }

解决方法

我猜你指定的选项永远不会被应用.这将解释为什么在提交表单后,在上传时已处理表单时,为什么没有文件附加到模型中.

要正确应用所需的选项,您需要关闭Dropzone的
auto discovery function：

Dropzone.autoDiscover = false;

这样你必须要programmatically initialize Dropzone：

var myDropzone = new Dropzone('form',{
    paramName: 'files',maxFiles: 1
});

Demo

autoProcessQueue

When set to false you have to call myDropzone.processQueue() yourself in order to upload the dropped files. See below for more information on handling queues.
