Expanding ClowderFileSystem to select Folders as well

[Vismayak]

The FileSystemViewer's functionality has been expanded to support the selection of folders. This enhancement enables passing folders as parameters to extractors that require folder inputs. For instance, a fine-tuning extractor might need a folder containing multiple photos.

Testing this feature is similar to the process outlined in PR #1103.

How to Test

1. Prepare an extractor:

   • Run an extractor locally. For this example, the wordcount extractor was used.
   • Add a new parameter in the extractor-info.json file under the schema field of parameters. If using the wordcount extractor, modify the file here:

     "FOLDER_SELECTION": {
         "type": "string",
         "title": "Details of the Clowder Folder",
         "description": "The Clowder file id of the dataset folder to be used for inference",
         "format": "ClowderFile",
         "showOnlyDatasetFiles": false,
         "selectFolder": true
     }

2. Create test data:

   • Create a dataset with a folder and a file inside it.

3. Run the extractor:

   • Execute the extractor within the dataset. Open the extractor interface and access the file selector. The file system will be displayed, allowing selection of both files and folders. However, since selectFolder is set to true, the "Confirm" button will be disabled when files are selected.

     

4. Select a folder:

   • Choose a folder, confirm the selection and submit the extractor

     

5. Verify extractor logs:

   • Check the extractor logs to confirm that FOLDER_SELECTION appears as a parameter in the default check message. It is ok if the extractor gives an error, we are just testing the component is working as requested. The JSON is sent as a string

     

6. Test additional behavior:

   • Re-run the extractor after setting showOnlyDatasetFiles to true (or removing it). This change restricts the file system view to show only files and folders within the dataset being processed.
