Multiple records not available when creating .CSV - ruby-on-rails

Question

#orders should have multiple orders yet when using a respond_to to create an CSV, I only have one order record available in my cvs.erb file. Here's the code.
reports_controller.rb
def orders
params[:q] = {} unless params[:q]
if params[:q][:completed_at_gt].blank?
params[:q][:completed_at_gt] = Time.zone.now.beginning_of_month
else
params[:q][:completed_at_gt] = Time.zone.parse(params[:q][:completed_at_gt]).beginning_of_day rescue Time.zone.now.beginning_of_month
end
if params[:q] && !params[:q][:completed_at_lt].blank?
params[:q][:completed_at_lt] = Time.zone.parse(params[:q][:completed_at_lt]).end_of_day rescue ""
end
params[:q][:s] ||= "completed_at desc"
#search = Order.complete.ransack(params[:q])
#orders = #search.result
respond_to do |format|
format.html
format.csv do
headers['Content-Disposition'] = "attachment; filename=\"Order-List\"#{Date.today}"
headers['Content-Type'] ||= 'text/csv'
end
end
end
order_items.csv.erb
<%- headers = ['Order Number', 'User', 'Item Total', 'Discount Value', 'Sales Total', 'Promotions'] -%>
<%= CSV.generate_line headers %>
<%- #orders.each do |order| -%>
<%= CSV.generate_line([order.number, order.email, order.item_total, order.promo_total, order.total]) %>
<%- end -%>
order_items.html.erb
<%= search_form_for #search, :url => spree.order_items_admin_reports_path do |s| %>
<div class="form-group date-range-filter">
<%= label_tag nil, Spree.t(:date_range) %>
<div class="date-range-filter row">
<div class="col-md-6">
<%= s.text_field :completed_at_gt, :class => 'datepicker datepicker-from form-control', :value => datepicker_field_value(params[:q][:completed_at_gt]) %>
</div>
<div class="col-md-6">
<%= s.text_field :completed_at_lt, :class => 'datepicker datepicker-to form-control', :value => datepicker_field_value(params[:q][:completed_at_lt]) %>
</div>
</div>
</div>
<div class="form-actions">
<%= button Spree.t(:search), 'search' %>
</div>
<%= link_to "Export CSV", order_items_admin_reports_path(format: 'csv', :params[:q] => params[:q]), {:style => 'margin-top: 50px; margin-bottom: 20px;', :class => "btn btn-primary btn-success"} %>
<% end %>
