Create method not submitting POST request - ruby-on-rails

Question

I have a controller in a rails app whereby a user can create a holiday request, it seems that when I fill out the necessary information it is not doing the POST request and submitting my form. My output in the RailsPanel follows: Rails Panel. From this its as if it is doing the GET request when surely on it should do a GET then a POST. I believe I have messed up somewhere around my create method. Any feedback would be great thank you!
controller
class HolidaysController < ApplicationController
before_filter :authenticate_user!
before_filter :admin_user, :only => [:index, :update, :edit, :absence]
before_filter :correct_user, :only => [:delete]

#holiday = Holiday.new
#user = current_user

#holiday = Holiday.find(params[:id])
c_u = current_user

#user = current_user
#holiday = current.holidays.build(params[:holiday])
#holiday.approver_id = approval_method(current_user, #holiday)

#otherwise an admin sees the holiday requests that they are approvers for

Answer 1

The reason is, you are having a form in your holidays/show.html.erb but not in your holidays/new.html.erb.
According to rails convention, if form is submitted in new.html.erb, then by default the POST method is called of that particular controller.
But since your file is show.html.erb, you have to explicitly define your POST method in the form_for.
form_for #holiday , :url => { :action => :create }, :html => { :method => "post"} do |f|
