Rails, Polymorphic Association - Display only related instances

I am trying to learn how to use polymorphic associations in my Rails 5 application.

I have models called Organization, Offer and Package :: Bip.

Associations:

Organization

 has_many :bips, as: :ipable, class_name: Package::Bip
    accepts_nested_attributes_for :bips,  reject_if: :all_blank, allow_destroy: true

Sentence

has_many :bips, as: :ipable, class_name: Package::Bip
    accepts_nested_attributes_for :bips,  reject_if: :all_blank, allow_destroy: true

Package :: Beep

belongs_to :ipable, :polymorphic => true, optional: true, inverse_of: :bip

Package :: Bip can be associated with either the Organization or the proposal. I am struggling to figure out how to show the package :: Bips, which belong only to the proposal in my proposal, and the same goes for the organization.

My package :: beep table has these 2 columns:

#  ipable_id      :integer
#  ipable_type    :string

The type is set either in the proposal or in the organization.

In my sentence sentence, I have:

<% if @proposal.bips.present? %>
    <%= link_to package_bips_path(@proposal) do %> 
<% end %>

, (@proposal) package_bip . . , , package_bips ( , ).

:

    def show
    @images = @proposal.images
    @bips = @proposal.bips.where(ipable_type: 'Proposal')
  end

, , , , ipable_type, .

, if Package:: Bips, , ipable_type. , , ( , , ).

Package:: Bips :

def index


    if params[:ipable_type]
      @bips = Package::Bip.where(ipable_type: 'Proposal')
    elsif params[:ipable_type]
      @bips = Package::Bip.where(ipable_type: 'Organisation')
    else
       @bips = Package::Bip.all
