How to make a model or a model decorator aware of its controller in Rails?

Is a decorator, like Draper, a good place to store the controller and
routes associated with a given model?

I would like to be able to pass one or several model objects to a
generic
view, and have the view automatically generate links to the actions
associated with the objects. Like this:

link_to object.public_send(attribute),
{ :controller => object.controller_path,
:action => :show,
:id => object.id }

Thank you for any suggestions of what would be a common practice.

I have also posted this question on
SO: http://stackoverflow.com/questions/12713784.

I will answer myself: i think a decorator is not a good place to store
an
associated controller, a decorator should only know about model data and
HTML markup. I am still looking for a good solution.

In your example, the controller path seems highly relevant to
generating
HTML markup…

You could check out http://objectsonrails.com/ and
https://github.com/objects-on-rails/display-case - as it says, it
brings together the model and context (which could be a controller)

Matt, i do not agree: if my application changes the host, or i decide to
change route names or controller names, the link urls will change, but
html
tags or model behavior will not. I think controller awareness should be
added on a different level, not in a decorator (single responsibility
principle).
