i received this error 'Unpermitted parameter: image' in nested parameter

Question

this is my profiles_controller.rb

 def create

 @profile = current_user.build_profile(profile_params)

  if @profile.save
  else
    render :new 
  end
 end
 end

profile.rb has a nested attributes from image.rb

  params.require(:profile).permit(:first_name, :last_name, :phone_no, image_attributes: [:id,:image,:imageable_id,:imageable_type])

This is profile.rb

 class Profile < ActiveRecord::Base
 belongs_to :user
 has_one :image , :as => :imageable
 accepts_nested_attributes_for :image
 end

this is image.rb

  class Image < ActiveRecord::Base
  belongs_to :imageable, polymorphic: true
  mount_uploader :image, ImageUploader
   end

this is _form.html.erb from profile.rb model

   <%= f.fields_for :image do |ff| %>
   <%= f.label :image %>
   <%= f.file_field :image %>
   <% end %>

Answer 1

<%= f.fields_for :image do |ff| %>
  <%= ff.label :image %> 
  <%= ff.file_field :image %>
<% end %>
