Class name to view path

Question

Hi,

I have a RoR application and model SomeModel. I have views for this model and I want to know - is there any method to get the view's path? Of course I can use for this model instance

m = SomeModel.new
v = m.class.class_name.pluralize.downcase

It's working, but maybe you know a better way? :)

Answer 1

Views working with models through controllers layer. Every view is corresponded to some rout/controller action. So path to views related with controller name: app/views/some_controller/{bunch of files}.html.erb

It is not always true, that your views dirname will referred to your model name. So there is not universal method to find out views dirname.

Your solution is suitable but not in all cases

Answer 2

As @fl00r said, no, there's no general method to do this, as the names of all the views depend on the individual application implementations (not every controller is a resource controller), but you can certainly write some helpers so that you don't have to type m.class.class_name.pluralize.downcase frequently.

module ViewPathHelper
  def resource_view_path(model_obj, action)
     "#{model_object.class.class_name.pluralize.downcase}/#{action}"
  end
end

would be one way to do so.

This seems a somewhat strange request - what do you need the view path for anyway? Are you doing something highly polymorphic? (Because there's this thing called polymorphic_path ...)

Answer 3

If you feel you need the path to a view in your model, chances are you are putting logic into your model that belongs in the controller or helper. You might reconsider how you are partitioning your MVC logic.
