rendering images located outside of public directory

[Caveman Pl]

Hi group,

I have no idea how to export images located outside of public directory.

Forgive me to disturbing groups such a lame questions but cant find  working example with google... 

I have a route

$r->get('/pdataexport_qc')->to('Pdataexport#showQC');

$r->post('/showqcshowimg')->to('Pdataexport#showQCshowIMG');

in my Pdataexport.pm

sub showQC{
    my $self = shift;
    my $pDataPath = $self->config('phenotypeDataFromResoraDbFilesPath');
    my $dir = $self->param('dir');

    $self->stash( dirToQC => $dir);

    $self->render('phenotypeExport/showDataQC');

}

my template phenotypeExport/showDataQC.html.ep

% layout 'all';

<table border="0" style="border-collapse: collapse;">
<tr><td><img src="https://192.168.11.11:1777/showqcshowimg?dir=<%=$dirToQC%>&img=AH1vsAGE.png"></td></tr>
</table>
</body>
</html>

which generates me nice url

<table border="0" style="border-collapse: collapse;">
<tr><td><img src="https://192.168.11.11:1777/showqcshowimg?dir=2018-04-03-18-32-46_G&img=AH1vsAGE.png">

</table>
</table>

but in log output I can see that was not routed to showqcshowimg

sub showQCshowIMG {
    my $self = shift;
    my $img = $self->param('img');
    my $dir = $self->param('dir');
    my $pDataPath = $self->config('phenotypeDataFromResoraDbFilesPath');
    $self->render_file(filepath => $pDataPath.$dir."/".$img, 'filename' => $img );
}

Can you give a simpe example how it should be done?

or maybe you know page or open project which can play as example?

Thank you,

tj

Sorry, your issue is in routing: your showimg route is POST-only, but browsers will always use GET to request an image.

Hi Dan,

Changing 

$r->post('/showqcshowimg')->to('Pdataexport#showQCshowIMG');

to

$r->get('/showqcshowimg')->to('Pdataexport#showQCshowIMG');

doesn't help.

Thank you,

I might be off base, but I'm wondering if what you're looking for is how to serve static files from a non default location?

http://mojolicious.org/perldoc/Mojolicious#static

[Caveman Pl]

Hi Stefan,

Yes they are static files outside dir tree generated by command "mojo generate app" which is located in my home dir /home/tomasz/work/mojo/my_app/. 

I have tryed also inlib/MyApp.pm

use Mojolicious::Static;

my $static = Mojolicious::Static->new;

push @{$static->paths}, '/data/common/mojo/';

and than in phenotypeExport/showDataQC.html.ep

<img src="<%=$dirToQC%>/AH1vsAGE.png">

which create nice url in generated page 

<img src="/data/common/mojo/2018-04-03-18-32-46_G/AH1vsAGE.png">

but it doesnt work also...

Thank you,

tj

I don't think you want to create a new object, you want to modify the current app.

Instead, $app->static->paths

Sent from my phone...

[Caveman Pl]

didnt know what an $app object is...

but found this page http://blogs.perl.org/users/revlin_john/2013/03/re-simple-webserver---serve-static-files-with-mojolicious.html

when I add to startup subroutine in lib/MyApp.pm

push @{$self->static->paths}, '/data/common/mojo/';

nothing is happen - image doesnt appear on page

when try to add

use Mojolicious::Lite;
my $app = app;
my $static = $app->static;

all hangs...

<img src="..."> is the browser URL, not the absolute path of the file on the server. So if you add '/data/common/mojo' to the static paths, the tag for '/data/common/mojo/2018-04-03-18-32-46_G/AH1vsAGE.png' is

<img src="/2018-04-03-18-32-46_G/AH1vsAGE.png">
