Hi! I'm trying to create a dynamic page that shows the content of a file in a webpage using perl and mojolicious. For future reference, I need to display de data and be able to manipulate it and save the file again. Maybe some of you know a better way to handle this than mojolicious, but, meanwhile...
I have been reading several blogs and posts (mostly this <https://github.com/kraih/mojo/wiki/Recipes-for-templates>) to know how to pass the value of an array to a html layout to display the data, but I think I don't understand how this works. I think that the bit that I need it's the last one of that page <https://github.com/kraih/mojo/wiki/Recipes-for-templates#passing-a-arrayref-to-the-stash> but I'm struggling to get the array at the site and I don't know how to move on. The reading file part it's not there because I prefer dealing with just one thing at a time to isolate issues and make the development easier. My code looks like this right now: #!/usr/bin/env perl use Mojolicious::Lite; my @ref_pets = (); for(my $i=0; $i<=10;$i++){ # $ref_pets = $ref_pets.',[n='.$i.']'; push @ref_pets, $i; } # for(my $i=0; $i<=10;$i++){ # say @ref_pets[$i]; # } for my $loop(@ref_pets){ say $loop; } get '/' => sub { my $self = shift; # $ref_pets = $ref_pets.',['isolde','cat'],['oscar','dog']'; $self->stash( ref_pets_stash => @ref_pets ); } => 'index'; app->start('daemon', '-l', 'http://*:8080'); __DATA__ @@ index.html.ep %layout 'default'; <p>Welcome to arratrefs</p> <p> <ul> %for my $loop (@{@ref_pets_stash}){ <li>Name of the pet: <%= $loop-> %></li> %}; </ul> </p> @@ layouts/default.html.ep <!doctype html><html> <head> <title>Default</title> </head> <body> <%== content%> </body> </html> And when running the code, the terminal output it's this: $ perl .\Data-to-stash-TEST.pl 0 1 2 3 4 5 6 7 8 9 10 [Thu Aug 17 09:12:33 2017] [info] Listening at "http://*:8080"; Server available at http://127.0.0.1:8080 and after enter the url of the server: [Thu Aug 17 09:14:23 2017] [debug] Inactivity timeout [Thu Aug 17 09:14:53 2017] [debug] GET "/" [Thu Aug 17 09:14:53 2017] [debug] Routing to a callback [Thu Aug 17 09:14:53 2017] [debug] Rendering template "index.html.ep" from DATA section [Thu Aug 17 09:14:53 2017] [error] Can't use global $1 in "my" at template index.html.ep from DATA section line 1, near ",$1" Global symbol "$cb" requires explicit package name (did you forget to declare "my $cb"?) at template index.html.ep from DATA section line 1.
