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