Re: [EP-tech] Adding user messages from CGI

Interesting.  I had thought it was easier than this, but a scan of the code shows that this is, indeed, what's happening.  It's used 'officially' only a couple of times, but the key example is when you take an edit lock from someone it shows them a message (see https://github.com/eprints/eprints/blob/33a7bb8a8b3f80ba02ddd6618eb4e7dc3209ec68/perl_lib/EPrints/Plugin/Screen/EPrint/TakeLock.pm#L72 )

I would, however, say that if you're having to jump through hoops like this, your approach may be wrong.  The screen plugin infrastructure is there to manage things like this.  What are you doing with the cgi script, and why can't it be a screen plugin?

Subject: Re: [EP-tech] Adding user messages from CGI

Thanks for the response Yuri, but I'm trying to add a 'job done' message for the user to see once they have been sent back to their home deposit screen, rather than generate the appropriate HTML to render immediately.

However, as so often seems to happen, I think I've got an answer, assuming the user visiting the cgi is logged in:

my $repo = new EPrints::Session;
my $db = $repo->database;
my $current_user = $repo->current_user();
my $xml_dom_value = $current_user->render_value( "name" );  # render the user name as an example

$db->save_user_message($current_user->get_value( "userid" ),
"message",
$repo->html_phrase("html_phrase_id", ("pin_name"=>$xml_dom_value)));


I'll try and find somewhere useful on the Wiki to add it.

Cheers,
Alan

from cgi/logout:

$page->appendChild( $session->render_message(
    "message",
    $session->make_text( "Logout OK!" ) ) );

add_message works only in plugins, and it calls $session->render_message anyway.

Any clue if there is a function to add a message to the message queue
from a cgi script?  I can use $self->{processor}->add_message() from
within a plugin but how do I do this without a '$self' ?

Cheers,

Alan
