如何将angular-file-upload中的用户id与rails相关联

Question

我在Rails中使用angular-file-upload ( https://github.com/nervgh/angular-file-upload )。当我上传照片时，我想关联外键的用户id。

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

您可能希望这样做：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
    ]
});

这将为请求添加一个包含用户id的新参数，然后在rails控制器中可以执行以下操作：

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