getBlobURL

Uses the data handler getBlobURL of the data object to get a pathname for a file. Can be given either a primkey, field and file name as parameters, or a record with PrimKey and FileName fields and a field value.

If you give a record, and the record does not have both PrimKey and FileName fields, an empty string will be returned.

Usage

You can give a specific primary key and file name directly. In this example we have a data object with an Image blob field. The field doesn't need to be in the data object, but must exist in the view used by the data object.

function MyComponent({ record }) {
  return (
    <img
      src={dsMyDataObject.getBlobURL(
        record.PrimKey,
        "Image",
        `avatar-${record.ImageHash}.jpg`
      )}
      alt={record.FullName}
    />
  );
}

Alternatively, if the data object has both a field called PrimKey and a field called FileName, you can pass the record directly to the method:

function MyComponent({ record }) {
  return <img src={dsMyDataObject.getBlobURL(record, "Image"} alt={record.FullName} />
}

API

While there is a parameter to choose if you want to download or view the file, it currently does not affect the URL returned, as this is not implemented for blob file handlers

getBlobURL(record: Record<string, any>, field: string, type?: "download" | "view"): string;
getBlobURL(primKey: string, field: string, fileName: string, type?: "download" | "view"): string;
