how to change the domain using rails path helper?

Question

So Rails provides these path helpers, for example, I can, in a view file, have

<%= link_to "edit", edit_admin_article_path(article) %>

This would work both in development environment (localhost) or in production environment. For development, it would generate url

http://localhost:3000/admin/articles/1018/edit

For production, it would generate

http://www.mydomain.com/admin/articles/1018/edit

My question is: how do I force the url to always be the production link even in the development environment? Can I pass a domain value in a hash to the edit_admin_article_path() call?

Thank you.

Answer 1

You probably want the url helper, it will take a domain as an option and make a fqdn.

edit_admin_article_url(article, domain: "production.tld")

It will also pick up any constraints you might have added in the routes.

Answer 2

Edit

For newer version of Rails use

edit_admin_article_url(article, domain: "example.com")

Original answer (Rails 3)

Try

<%= link_to "edit", "http://www.example.com" + edit_admin_article_path(article) %>

You could of course refactor the http://www.example.com part into a helper method, that way you don't have to keep track of it everywhere if/when you want to change it.

Or you could create an absolute_link_to method that does what you want by just wrapping the link_to method.
