Rails, fields_for nested attributes - Avoid displaying existing objects on edit - ruby-on-rails

Question

I am trying to have my Edit form only allow for the creation of new elements. Currently it automatically displays all of the existing elements. Below is my current code. I have a standard has_many, belongs_to relationship between Orders and Documents. I only want the ability for users to add new documents and never edit the existing documents. With the current code It displays all associated Documents on the edit form.
<%= f.fields_for :documents, child_index: Time.now.to_i do |document| %>
<div class="col-md-5">
<%= document.label :doc_type, "Type", :style => "color:red;" %>
<%= document.collection_select :doc_type_id, DocType.order(:name), :id, :name, { prompt: true, class: "form-full"} %>
<br>
</div>
<div class="col-md-7">
<%= document.label :description,"Description **", :style => "color:red;" %>
<%= document.text_field :description, style:"color:black;" %>
<br>
</div>
<div class="col-md-12">
<br>
<%= document.file_field :doc, style:"color:white;" %>
</div>
<div class="col-md-12" style="background:#272727;">
<hr class="style2">
</div>
<% end %>
class Order < ActiveRecord::Base
belongs_to :user
has_many :properties, :dependent => :destroy
has_many :documents, :dependent => :destroy
accepts_nested_attributes_for :documents,
:allow_destroy => true,
:reject_if => :all_blank
accepts_nested_attributes_for :properties,
reject_if: proc { |att| att["city"].blank? }
end
class Document < ActiveRecord::Base
belongs_to :order
belongs_to :doc_type
end
With The below code I was able to have the form appear correctly (not showing existing Documents) but when adding a new Document via the Edit form, the Document is never actually created.
<% if !current_page?(action: 'edit') %>
<%= f.fields_for :documents, child_index: Time.now.to_i do |document| %>
<div class="col-md-5">
<%= document.label :doc_type, "Type", :style => "color:red;" %>
<%= document.collection_select :doc_type_id, DocType.order(:name), :id, :name, { prompt: true, class: "form-full"} %>
<br>
</div>
<div class="col-md-7">
<%= document.label :description,"Description **", :style => "color:red;" %>
<%= document.text_field :description, style:"color:black;" %>
<br>
</div>
<div class="col-md-12">
<br>
<%= document.file_field :doc, style:"color:white;" %>
</div>
<div class="col-md-12" style="background:#272727;">
<hr class="style2">
</div>
<% end %>
<% else %>
<%= f.fields_for #order.documents.build, child_index: Time.now.to_i do |document| %>
<div class="col-md-5">
<%= document.label :doc_type, "Type", :style => "color:red;" %>
<%= document.collection_select :doc_type_id, DocType.order(:name), :id, :name, { prompt: true, class: "form-full"} %>
<br>
</div>
<div class="col-md-7">
<%= document.label :description,"Description **", :style => "color:red;" %>
<%= document.text_field :description, style:"color:black;" %>
<br>
</div>
<div class="col-md-12">
<br>
<%= document.file_field :doc, style:"color:white;" %>
</div>
<div class="col-md-12" style="background:#272727;">
<hr class="style2">
</div>
<% end %>
<% end %>
Any help/advice/resources would be appreciated. Been stuck on this for a bit. Also I have not refactored into partials yet so please forgive the messiness.
THANKS!!
