Pass value from one router to another using Mojolicious::Lite - perl

Question

from an ajax form this router foundname gets called, I need to process the value and pass it to another router, I can't figured it out how to do it, here is a sample of how I am trying:
#!/usr/bin/perl
use Mojolicious::Lite;
get '/foundname' => sub {
my $c = shift;
# Here I get the value from the form
my $name_on = $c->req->query_params->param('name');
if($name_on) {
# call another router and pass the name value to it
# It gives an error "Can't locate object method "get" ", I might not need to use "get", just don't know how to pass the value.
$c->get('/process_name')->to( searched => $name_on);
}
};
get '/process_name' => sub {
my $c = shift;
my $got_name = $c->req->query_params->param('searched');
...
};
Thank you!

You need to look up the routes through your Mojolicious::Routes object inside of your app. The name for the lookup is auto-generated by Mojolicious::Lite from the path-part of the URI, so /process_name has the name process_name.
You get back a Mojolicious::Routes::Route, which has a render method and you can pass your parameters along there.
use Mojolicious::Lite;
get '/foundname' => sub {
my $c = shift;
my $name_on = $c->req->query_params->param('name');
if( $name_on ) {
my $process_name = app->routes->lookup('process_name')->render( { searched => $name_on } );
$c->render( text => $process_name );
}
};
get '/process_name' => sub {
my $c = shift;
my $got_name = $c->req->query_params->param('searched');
$c->render( text => $got_name );
};
app->start;
When you curl this you get the parameter back as a response.
$ curl localhost:3000/foundname?name=foo
/process_name
However, this is probably not the right approach. If you want to implement business logic, you should not use internal or hidden routes for that. Remember that your application is still just Perl. You can write a sub and call that.
use Mojolicious::Lite;
get '/foundname' => sub {
my $c = shift;
my $name_on = $c->req->query_params->param('name');
if( $name_on ) {
my $got_name = process_name( $name_on );
$c->render( text => $got_name );
}
};
sub process_name {
my ( $got_name ) = #_;
# do stuff with $got_name
return uc $got_name;
};
app->start;
This will output
$ curl localhost:3000/foundname?name=foo
FOO
It's the more portable approach, as you can easily unit-test these functions. If you want to have $c, you have to pass it along. You also have the app keyword available in any sub you define.

For the original question, I would use
$c->redirect_to()
See this question for details on passing the variable over:
Passing arguments to redirect_to in mojolicious and using them in the target controller
======
But, I would look more into writing subs (as others have said).
If you have existing logic then you can wrap it in a helper or just toss the logic in a helper and call that.
helper('process_name'=> sub{
my $self,$args = #_;
# Do some logic with $args->{'name'}
return $something;
});
get '/foundname' => sub {
my $c = shift;
my $name_on = $c->req->query_params->param('name');
if( $name_on ) {
my $process_name = $c->process_name({name => $name_on});
$c->render( text => $process_name );
}else{
$c->redner(text => 'Error',status=>500);
}
};
