how do i automatically click the link when page loads in rails

In controller

if params[:name]==params[:name]   
  @categories=Category.where(:hotel_id=>params[:hotel_id])
  @menus=Menu.where(:category_id=> params[:id]).sorted   
  @cart = current_cart
end

In index page:

<%@categories.each do |d|%>
<%= link_to d.name ,{:action=>'index',:id=>d.id,:hotel_id=>d.hotel_id},class: "btn-orange" %>

use each_with_index to get/detect the first element(this is what you want) and then click it using jquery

view file

<%@categories.each_with_index do |d,index|%>

<%= link_to d.name ,{:action=>'index',:id=>d.id,:hotel_id=>d.hotel_id},id:first_"#{index}",class: "btn-orange" %>       

<%end%>

====================js code to click when page is ready============

$(document).ready(function(){

setTimeout(function() {
   //click after 2 seconds when page loads or remove it or use=> $('#first_0').trigger('click'); directly without setTimeout in document.ready()
   $("#first_0").click();
}, 2000);

})//document ends

To answer your question bluntly, you'll have to use JQuery to invoke the click event:

#app/assets/javascripts/application.js
var loaded = function(){
   $("a.first_link").trigger("click");
};
$(document).on("page:load ready", loaded);

Structure

Needless to say, this does not mean you'll be making a robust, efficient system. Instead, it means you'll be calling an event which you shouldn't need to.

As mentioned in the comments, it looks like your controller is the place where this type of business logic should occur:

#config/routes.rb
resources :hotels do
   resources :categories
end

#app/models/hotel.rb
class Hotel < ActiveRecord::Base
   has_many :categories
end

#app/models/category.rb
class Category < ActiveRecord::Base
   has_many :menus
end

#app/controllers/categories_controller.rb
class CategoriesController < ApplicationController
   before_action :set_cart

   def index
      @hotel =      Hotel.find params[:hotel_id]
      @categories = @hotel.categories      
      @menus =      @categories.find(params[:id]).menus.sorted
   end

   private

   def set_cart
      @cart = current_cart 
   end
end

You can use trigger to call action on jquery, as the following: 

$(documnet).on("page:load ready", function(){
  $("a.first_link").trigger("click");
})

You can read more trigger, and load page event.
