===Making the page appear===
 
−
There are three steps to making a page appear:
 
−
 
 
−
1. The Perl Package should test for ''view-ability''
 
−
<pre>
 
−
# in EPrints::Plugin::Screen::Mypackage
 
−
sub can_be_viewed
 
−
{
 
−
my( $self ) = @_;
 
−
return $self->allow( "my/conf/value" );
 
−
}
 
−
</pre>
 
−
2 The ''User'' DataObject needs to list the privilege under a role:
 
−
<pre>
 
−
  # In EPrints::DataObj::User
 
−
  foo_bar => [
 
−
    "my/view/value",
 
−
  ],
 
−
  foo_baz => [
 
−
    "my/view/value",
 
−
    "my/conf/value",
 
−
  ],
 
−
</pre>
 
−
3 The user_roles.pl file needs to make the role available to the user-type:
 
−
<pre>
 
−
# in [eprints]/archive/<ARCHIVE_ID>/cfg/cfg/user_roles.pl
 
−
$c->{user_roles}->{user} = [qw{
 
−
// truncated
 
−
foo_bar
 
−
}],
 
−
$c->{user_roles}->{admin} = [qw{
 
−
        // truncated
 
−
foo_baz
 
−
}],
 
−
</pre>
 
−

Screen Plugins are used to handle the User Interface. Screen plugins provide the UI to the user-interaction parts of EPrints. A screen plugin can include:

  • A render - several pages (like a search) or none (like the eprint move plugin). Most have a single page of output.
  • Actions - things which modify the system in some way.
  • Rights testing - the entire plugin, and individual actions, can be restricted in various ways.
