How to loop through multiple polymorphic models?

Question

I don't know how to make a loop that goes through 2 models apart of the polymorphic association I have. I have the models User , Follow , Dad and Mom .

class User
 has_many :follows
end

class Mom
  has_many :follows, as: :followable
  # columns: name, :address
end

class Dad
  has_many :follows, as: :followable
  # columns: name
end

class Follow
 belongs_to :user
 belongs_to :followable, polymorphic: true
 # columns: user_id, followable_id, followable_type
end

My goal is to loop through the moms and dads that the user is following and get there specific attributes like this:

# FollowsController

index
 # follows = dads and moms
 @follows = current_user.follows.paginate(page: params[:page])
end

# follows/index.html.erb

<% @follows.each do |f| %>
 <%= f.dad.name %>
 <%= f.mom.name %>
 <%= f.mom.address %>
<% end %>

How would this be done?

Answer 1

You just need to use

f.followable.name
f.followable.address

If you want to check if it is dad or mom then you can check it like this

f.followable_type == 'Dad'

Or

f.followable.kind_of?(Dad)
