Back to cfg.d

document_fields_default.pl contains the set_document_defaults function. This function sets the default values for a Document. This usually happens when a Document is created but before it is given to the user to edit.

  • $data is a hash reference of the metadata which will make up the document object. Each field name is a key in the hash.
  • $session is a Repository object (in 3.2 or later).
  • $eprint is the EPrint object to which the document belongs.

Example[edit]

In this example, the default for language is set to the ID string of for the Repository object's language, which comes from the $c->{defaultlanguage} configuration setting in languages.pl and the default for security is set to public.

$c->{set_document_defaults} = sub
{
        my( $data, $session, $eprint ) = @_;

        $data->{language} = $session->get_langid();
        $data->{security} = "public";
};

N.B. There are also a number of defaults set by the EPrints::DataObj::Document::get_defaults method:

  1. pos is set to the next document position or to a bespoke position specified by $c->{ulimate_doc_pos} if it is defined.
  2. placement is set to the same value as pos as set above.
