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

I suppose it could actually be a screen plugin – I’m handling a return redirection from the ORCID API and I lifted some of my design etc. from Peter West’s Tier 2 API plugin, which uses a CGI script as the return page.

 

It’s not actually that many hoops as I already needed the repo, db and user objects for processing the response, so it’s only really a one-liner to add the message – I just broke it out more for clarity in the email.

 

I’ll consider the best approach though.

 

(the return redirect URI has to be pre-registered with ORCID, which may involve some hoop jumping to change from my current CGI address, but I could always just bounce the CGI landing page on to the screen plugin, with some validation).

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?

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,
