Incapable de convertir les paramètres non autorisés en hash rails

Question

J'essayais d'ajouter un fichier CSV pour mes résultats de recherche mais il renvoie une erreur indiquant des paramètres non autorisés. Quels paramètres dois-je passer dans le lien CSV? Afin que le CSV télécharge uniquement les résultats de la recherche.

ReportsController

def revenue_search
  @bookings = Booking.complete.order("created_at DESC")
  date = "1-#{params['date']['month']}-#{params['date']['year']}"
  date = Date.parse(date)
  @bookings = @bookings.where(created_at: date.beginning_of_month..date.end_of_month)
  @per_page = params[:per_page] || Booking.per_page || 20
  @bookings = @bookings.paginate( :per_page => @per_page, :page => params[:page])
  if params[:currency].present?
    @bookings = @bookings.where(currency: params[:currency])
  end
  respond_to do |format|
    format.html
    format.csv { send_data @bookings.revenue_csv }
  end
end

Model

def self.revenue_csv
  attributes = %w{ total value deposit balance }
  CSV.generate(headers: true) do |csv|
   csv << attributes
   all.each do |booking|
    csv << attributes.map{ |attr| booking.send(attr) }
   end
 end
end

revenue.html.erb

<%= form_tag revenue_search_path, :method => 'get' do %>
   <%= select_tag(:currency, options_for_select(["USD", "GBP"]), class: "form-control custom-select" , :prompt => 'By Office' ) %>
   <%= select_month((@selected_date || Date.today), {}, class:"custom-select", :prompt => 'By Month')%>
   <%= select_year((@selected_year || Date.today.year), {},  class:"custom-select" )%>
   <%= submit_tag "Search", name: nil , class: "btn btn-info" %>
<% end %>

       Total d'étudiants
       Valeur des cours vendus
       Total des dépôts
       Paiements du solde

        <%= @bookings.count %>
        <%= @bookings.count %>
        <%= @bookings.sum{|x| (x.payment_gross.to_f)} %>
        <%= @bookings.sum{|x| (x.course&.course_fee || x.event&.course_fee).to_f - x.payment_gross.to_f  }.to_f %>

 Télécharger: <%= link_to "CSV",  revenue_search_path(format: "csv" , params: params ) %>

Vous pouvez utiliser to_unsafe_h

revenue_search_path(format: "csv" , params: params.to_unsafe_h)
