Instance Method Details

#allow_batch? ⇒ Boolean

Determine if the user can perform batch operations on this admin set. Currently, the only batch operation allowed is deleting, so this is equivalent to checking if the user can delete the admin set determined by criteria…

  • user must be able to edit the admin set to be able to delete it

  • the admin set itself must be able to be deleted (i.e., there cannot be any works in the admin set)

Returns:

  • (Boolean) —

    Boolean true if the user can perform batch actions; otherwise, false
