Rails: link_to - passing a subdomain

Question

I need to create a link_to to a different subdomain.

This is what I came up with:

= link_to "Link to Subdomain", root_path(subdomain: "abc", param1: "value1", param2: "value2")

It is not working though. I get redirected to:

http://lvh.me:3000/?param1=value1&param2=value2

Note: The as param passed subdomain is not being displayed in the url. Neither as subdomain nor as parameter.

Instead I want to get redirected to the following URL:

 http://abc.lvh.me:3000/?param1=value1&param2=value2

Answer 1

啊...你正在使用root_path ，根据定义它是一个相对url（即它不包含域）...你可能想要root_url ，它将完全指定域（和子域）。
