Re^2: Mojolicious absolute url with query in template? by Anonymous Monk on Mar 19, 2020 at 09:22 UTC
Thanks for replying. I tried adding ->query before asking the question, because it seemed logical, but it didn't work as expected. This displays the url without the query string: `<%= url_for('/')->to_abs %>` [download] But this displays absolutely nothing: `<%= url_for('/')->to_abs->query %>` [download] Here's the weird part, a link made with "to_abs->query" works, but can't be right clicked ("Void" link with click handler) and when source is viewed the href appears to be blank: `<a href="<%= url_for('/')->to_abs->query %>"> Reload </a>` [download] What is this voodoo?

You don't give any argument to `->query()`, so the query part is empty. If you want query parameters, you have to give them to the method, like haukex already demonstrated. `<a href="<%= url_for('/')->to_abs->query( foo => 'bar' )%>"> Reload </ +a>` [download] If you want to keep the current query parameters, you need to pass those into your template.

If you want to keep the current query parameters, you need to pass those into your template. Yes, or use `url_with` instead of `url_for`.	[reply] [d/l] [select]

Oh, I think I see what you're getting at. Note the documentation for `url_with`: Does the same as "url_for", but inherits query parameters from the current request. `<update>` Expanded `url_for` vs. `url_with` examples. `</update>` #!/usr/bin/env perl use Mojolicious::Lite -signatures; get '/' => sub ($c) { if ( !$c->param('foo') ) { $c->redirect_to( $c->url_for('index')->query(foo=>"bar") ) } else { $c->render('index') } } => 'index'; app->start; __DATA__ @@ index.html.ep % layout 'main', title => 'Hello, World!'; <pre> %= url_for('/') %= url_for('/')->to_abs %= url_for('/')->to_abs->query(abc=>"xyz") %= url_with('/') %= url_with('/')->to_abs %= url_with('/')->to_abs->query(abc=>"xyz") </pre> @@ layouts/main.html.ep <!DOCTYPE html> <html> <head><title><%= title %></title></head> <body><main> <%= content %> </main></body> </html> [download] Visiting `http://localhost:3000/` results in a single redirect (to add the query for demonstration purposes), and then renders as: `/ http://localhost:3000/ http://localhost:3000/?abc=xyz /?foo=bar http://localhost:3000/?foo=bar http://localhost:3000/?abc=xyz` [download] Also, note the `link_to` helper: `%= link_to Reload => url_with('/')->to_abs` results in `<a href="http://localhost:3000/?foo=bar">Reload</a>`	[reply] [d/l] [select]

Thank you haukex! I tried url_with too but was doing something stupid that only returned the query string: `url_with('/')->to_abs->query` [download] Your answer (of course) returns the absolute request url with query string: `url_with('/')->to_abs` [download] Also those link_to helpers are super cool. Now I see what Corion meant by passing params to the query method and why I'd want to do that.	[reply] [d/l] [select]
