url helper to generate absolute URL

[pke]

Currently the URL helper generates relative URLs. Is there a way to generate a fully qualified URL?

[joshbuddy]

yeah, I'm working on this now.

[pke]

Great, thanks!

[rainchen]

any progress?

[igorsantos07]

That would be a really useful feature.
Maybe it can be considered a regression, since "Padrino is based on Sinatra" and Sinatra offers this (in fact, by default).

[igorsantos07]

Is this issue abandoned?
Maybe I can take a look at it, as it looks fairly simply from my noob point of view.

You can use:

uri url(:controller, :action, :param => value)

@nesquena can you improve a guide with this?

[nesquena]

Sure, good idea

[igorsantos07]

GOD. Thanks, that solves the problem.
But where is the #uri method? I did a quick search and didn't find it in the API docs...

[nesquena]

It's actually part of sinatra: http://rubydoc.info/github/sinatra/sinatra/Sinatra/Helpers#uri-instance_method

[igorsantos07]

Hmmmm, I got it.
It's a little tricky (at least for me) because the alias #url is recreated
under Padrino, but #uri is not. By the method meaning, they should do the
same...
I still think that absolute urls should be generated by a method like
#abs_url or #url with an option like :absolute => true.

[rainchen]

how about using : only_path option, that is a rails style option for url_for :http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-url_for

[philipedwards]

What ended up being the outcome of this? I am having trouble finding the appropriate solution in the guides. How does one generate an absolute URL in padrino?

Don't know if any additional work has been done with this, but I just coded my own helper method in the meantime:

class MyApp < Padrino::Application
  configure :development do
    set :host, "http://localhost:3112"
  end

  def self.abs_url_for(*args)
    settings.host + url(*args)
  end
end

Use in views like MyApp.abs_url_for(), with same arguments as http://rubydoc.info/github/padrino/padrino-framework/master/Padrino/Routing/ClassMethods#url-instance_method Tried at first with Sinatra's uri mentioned earlier, but as I was trying to get this in a mailer view, was taking me down some rabbit holes as far as requiring libraries that aren't by default, so felt it was easier to just write my own little helper.

My two cents: felt kinda misleading coming over from Rails with this, as I would've expected url_for to give me an absolute url, and to have another method called path_for that gave me a relative path. At the very least, seems like there should be an option for url_for for outputting absolute urls.

@neezer +1

[dariocravero]

Why don't we add that helper and if the setting host is set it defaults to whatever its value is and otherwise it goes and looks for whatever uri can bring back?

[dariocravero]

@padrino/core-members thoughts?

[igorsantos07]

And then, one year later, I'm back in the same issue, trying to create an absolute URL inside a controller's method - to be used with a payment gateway.

Looks like #uri is not available there, although #url is - another sample of visible incompatibility between Sinatra and Padrino API's.

I'm trying to require the needed Sinatra files, but to no avail as well - I think I'm just too rusty with Ruby, after all.

Would there be a better way to do this?

App.controller :cart do |cart|
  def cart.do_stuff
    uri url(:cart, :success)
  end

  post :checkout do
    redirect_to cart.do_stuff
  end
end
