Rails how to request url except url params?

Question

I am creating this link tag:

<link rel="canonical" href="<%= request.url %>" />

The problem is just it is the full url with params.

How do I request the url without any params?

request is an ActionDispatch::Request and that subclasses Rack::Request. Rack::Request has a path method that might interest you:

<%= request.path %>

If your request.url is http://example.com/where/is?pancakes=house%3F then request.path should be /where/is.

I think James´ solution is the best choice in my case, because I need the full url, not just only the path. – Rails beginner Mar 28 '12 at 18:09
@Victor: Can you be a little more explicit about what "does not work" means? – mu is too short Dec 12 '12 at 03:30
Sure. `request.path` gives me the path and the parameters after `?`. `request.url.split('?').first` worked as expected. – Victor Pudeyev Dec 12 '12 at 03:52
@Victor: `request.path` isn't including the query string for me in 3.2 so I'm not sure what's up with your code. What sort of route are you using? – mu is too short Dec 12 '12 at 04:06
Well, I already solved the problem in my codebase. I'm working on other things now. Thanks for comments/answers. – Victor Pudeyev Dec 12 '12 at 20:56
