📌 Installation

💡 Usage

In your Nova resource class add NovaS3MultipartUpload tool to fields:

NB the make method requires a "human readable" name, it will try to guess the attribute name. You may pass the attribute name as a second argument.

NB the attribute name is used to store the file_path OR file/s information in case of storeAsArray/storeAsMultipleArray OR relationship model/s in case of hasOne/hasMany.

NB hasOne/hasMany methods are valid also for morphOne/morphMany

In your model class add all the attributes that will be filled to $fillable:

When using storeAsArray or storeAsMultipleArray methods you will need to cast the attribute to an array in your model class:

⚙️ S3 configuration

After creating your S3 bucket and connecting it to your Laravel project, You will need an extra step to configure the S3 bucket's "Cross-origin resource sharing (CORS)" with either JSON or XML (this is NOT the "Bucket policy"):

JSON

XML

NB please replace http://your-domain.com with your front-end domain.

✂️ Methods

• File storage:

  • ->disk($disk) Set S3 disk name, default is 's3'.

  • ->path($path) Set storage path, default is bucket root.

• Model attributes:

  By default the file_path is stored in the model attribute specified by the make method. Then if any other file information (file_name, file_size, metadata) are added they get stored in the corresponding attributes.

  For more flexibility all these attributes could be stored as an associative array under one single model attribute defined by make method.

  • ->storeAsArray($fileKeyColumn) Set the array key that will hold the file_path.

  • ->storeAsMultipleArray($fileKeyColumn) Like storeAsArray but allow multiple files.

  If you would like to store the file information in separate "child" model that is related to the "main" model attribute defined by make method.

✔️ Example

Uploading multiple files with their (names, sizes, metadata). Then save files information as multiple array in files attribute in User model.

User model class:

User resource class:

Preview:

When files are uploaded the user model files attribute \App\User::find(1)->files will have the following value:

🛂 Authorization

Nova authorize the user to see the resource tool using ->canSee(closure) method which accepts a Closure that should return true or false.

We have added more methods to this tool for more granulare control:

• ->canUpload(closure) allow the user to upload file and show the uploader panel.

• ->canView(closure) allow the user to list uploaded file and show the files grid.

• ->canDownload(closure) allow the user to download file and show the download button in the file card.

• ->canDelete(closure) allow the user to delete file and show the delete button in the file card.

e.g. if you would like to allow the user to upload only if no file attribute is empty:

e.g. if you would like to allow the user to delete files in his own model (Post or Video):

NB by default all actions are authorized until you disallow them.

🔌 Plugins

• Image Editor: enable Uppy Image Editor plugin using ->useImageEditor($array) method. The plugin is using the excellent Cropper.js.

  Options the method accepts an array of options:

  NB the editor will be only activated for image files.

• Webcam: enable Uppy Webcam plugin using ->useWebcam() method. Then you can record videos and take pictures to be uploaded.

  NB to be able to use the webcam you need https connection.

• Screen Capture: enable Uppy Screen Capture plugin using ->useScreenCapture() method. Then you can record your screen or applications to be uploaded.

  NB to be able to use the screen capture you need https connection.

⚠️ Notes

This package is a resource tool NOT a resource field. This means it is only visible under the resource detail view as a panel and can not be inserted in another panel or tab, it must be a direct child of the resource fields array.

Why? After a lot of thinking we found that uploading file in the same request of creating a new model is not a good idea. Because the response duration will depend on the file upload progress, which means the user have to wait without any visiual indication hoping that everything will work. So we decided to separate the files (upload | download | delete) process from the model (create | edit) process.
