Created page with 'catagory:snippits ==Why== There are a number of reason why you would want to add your own configuration data to EPrints. For me, I wanted to centralise the details for a dat…'

New page

[[catagory:snippits]]
==Why==
There are a number of reason why you would want to add your own configuration data to EPrints.

For me, I wanted to centralise the details for a database connection I needed for some secondary data (I had reasons for not including it in the main EPrints database)

==Setup==
To get the configuration variables into the system, the best way is to create a new configurations script:

<my_config.pl>
# {oarj} is the general configuration area
$c->{oarj} = {} unless exists $c->{oarj}; # only create it if it doesn't exist
# {db_conf} is a set of variables within that area
$c->{oarj}->{db_conf} = {
db_name => 'myDB',
db_hostname => 'some.host.name',
db_username => 'user',
db_password => 'password',
}

==Reading the configuration==
Once we have the configuration, we need to be able to read it back:

my $ep = $self->{session};
my $db_conf = $ep->get_repository->get_conf( "oarj","db_conf" );
my $dbh = DBI->connect(
"dbi:Pg:dbname=".$db_conf->{db_name}.";host=".$db_conf->{db_hostname},
$db_conf->{db_username},
$db_conf->{db_password},
{ AutoCommit => 0,
PrintError => 1,
showErrorStatment => 1
}
)
or $self->{processor}->add_message( "error",
$session->make_text("cannot connect to ".$db_conf->{db_name}.": $DBI::errstr") );

There you are...
