#Show get called controller method

I have a link to my #index

view:

<%= link_to 'Export Calendar (ICS)', { controller: :tickets, action: :ics_export, format: :ics }, class: "class-needed right" %>

      

        
        
        
      

    

routes.rb

which relates to this:

resources :tickets
get 'tickets/calendar' => 'tickets#ics_export'
post 'tickets' => 'tickets#index'
patch 'tickets/:id/close' => 'tickets#close', as: 'close_ticket'
post 'tickets/:id' => 'ticket_comments#create'

      

        
        
        
      

    

My TicketsController

that belongs to

before_action :set_ticket, only: [:show, :edit, :destroy, :update, :close]

def show
  @ticket_comment = TicketComment.new
end

def ics_export
  tickets = Ticket.all
  respond_to do |format|
    format.html
    format.ics do
      cal = Icalendar::Calendar.new
      tickets.each do |ticket|
        event = Icalendar::Event.new
        event.dtstart = ticket.start
        event.description = ticket.summary
        cal.add_event(event)
      end
      cal.publish
      render :text =>  cal.to_ical
    end
  end
end

private
def set_ticket
  @ticket = Ticket.find(params[:id])
end

      

        
        
        
      

    

And when I click on the link, it takes me back to /tickets/calendar.ics

, but that produces an error:

ActiveRecord::RecordNotFound in TicketsController#show

Couldn't find Ticket with 'id'=calendar

Extracted source (around line #83):

 private
 def set_ticket
   @ticket = Ticket.find(params[:id])
 end

      

        
        
        
      

    

Highlighted @ticket = Ticket.find(params[:id])

. It makes sense that he cannot name a ticket with an ID calendar

.

The request has parameters:

{"id"=>"calendar", "format"=>"ics"}

How do I fix this error? Why does he trigger the action of the show?
