Question

I’m making a Tweet This link in Rails. The URL I need to generate looks something like this:

http://twitter.com/share?url=http%3A%2F%2Fexample.com&text=Hello%20World

but a bit more complex. Basically a URL with a load of GET parameters appended

It would be nice to use one of Rails’ helpers, to generate this link, something like:

url_for("http://twitter.com/share", :url => "http://example.com", :text => "Hello world")

But I haven’t found anything that works. Anyone have any ideas?

Answer 1

You can call to_query on Hash in rails which will take care of url encoding etc. So maybe something like this:

params = {
  :a => "http://google.com",
  :b => 123
}
url = "http://example.com?#{params.to_query}"
