becomes(klass)
Returns an instance of the specified klass with the attributes of the
current record. This is mostly useful in relation to single-table
inheritance structures where you want a subclass to appear as the
superclass. This can be used along with record identification in
Action Pack to allow, say, Client < Company to do something like
render :partial => @client.becomes(Company) to render that instance
using the companies/company partial instead of clients/client.
Note: The new instance will share a link to the same attributes as the
original class. So any change to the attributes in either instance
will affect the other.
In your case: link_to ''Show'', credential.becomes(Credential)
You may also decide to have your controller specify the class instead,
there is probably a clean way but I don''t know it off the top of my
head.
