如何将 angular-file-upload 中的用户 ID 与 rails 相关联

Question

我正在将 angular-file-upload (https://github.com/nervgh/angular-file-upload) 与 Rails 一起使用。我想在上传照片时将用户 ID 关联到外键。

这将是模型的结构

用户有很多照片

示例代码：

var uploader = $scope.uploader = new FileUploader({
    url: 'http://localhost:3000/photos/'
});

HTML 代码：

<input type="file" nv-file-select="" uploader="uploader" multiple  /><br/>

<button type="button" class="btn btn-success btn-xs" ng-click="item.upload()" ng-disabled="item.isReady || item.isUploading || item.isSuccess">
                        <span class="glyphicon glyphicon-upload"></span> Upload


<button type="button" class="btn btn-success btn-s" ng-click="uploader.uploadAll()" ng-disabled="!uploader.getNotUploadedItems().length">
            <span class="glyphicon glyphicon-upload"></span> Upload all

Answer 1

你会想做这样的事情： assuming the user's id is in $scope.user.id

var uploader = $scope.uploader = new FileUploader({
    url: 'http://localhost:3000/photos/',
    formData: [
      user_id: $scope.user.id
    ]
});

这会为具有用户 ID 的请求添加一个新参数 然后在 Rails 控制器中，您可以执行以下操作：

@photo = Photo.create(photo: params[:file],user_id: params[:user_id])
