I'm following this answer on how to clone a record.
I can't though workout how to phrase the link and route it.
It is in my @miniature show view so I thought it should be something like
<%= link_to 'clone', :controller => :miniatures_controller, :action => :clone %>
and the route
match 'clone', to: 'miniatures#clone', via: 'get'
but this is clearly wrong. I am using @miniature in place of the above answer's @prescription.
