generate an real url with rails for an e-mail

问题

We want to send an autogenerated E-Mail with an full path to the profile. How do we this

<%=link_to('Link', :controller => 'mycontroller', :action => 'show', :id => @mycontroller.id )%> 

The link_to command only builds the link in the mail like this

mycontroller/show/id

we need an link like this structure

http://www.server.tld/mycontroller/show/id

Can everyone help us please?

回答1:

you can pass :only_path => false

<%= link_to('Link', :controller => 'mycontroller', :action => 'show', :id => @mycontroller.id, :only_path => false ) %>
