Question

I now have:

= link_to 'Back <', @discussable

And @discussable could be a course with a title, or a group with a name(I wish I used the same name). So I want to display “Back to *course_title*” or “Back to *group_name*” depending on the @discussable type. How do I do that? Thanks!

Answer 1

In your models, you can create a method that each model has to respond to, such as def title, and from there you would call that.

Example:

class Group < ActiveRecord::Base
  #code

  def title
    self.name
  end

end

class Student < ActiveRecord::Base
  #code

  def title
    self.full_name
  end

end

Then you would just do:

= link_to "Back to #{@discussable.title} <", @discussable
