undefined method `replies_path' RoR - ruby-on-rails

Question

I am literally pulling my hair out over here.
I am very new to Ruby on Rails. I did some tutorials and projects then decided to start off on my own on my own great project.
I got pretty far and am now adding Comments to my Tutorials...
(My "logic" got very confused. In my code, a comment is actually an answer to a "post." a reply is a "comment" to a tutorial.")
I used the Rails Console to create a reply. And that worked fine. So then I added the code "copy and pasted from an earlier project" using simple_form_for to create a comment on the tutorial page.
= simple_form_for(#reply, html: { class: 'form-horizontal' }) do |c|
= c.input :content, :label => false
= c.hidden_field :tutorial_id, :value => #tutorial.id
But when I reload my tutorial show page I get this error.
NoMethodError in Tutorials#show
Showing /home/gilbert/Rails_Projects/Seek-Rails-master/app/views/tutorials/show.html.haml where line #13 raised:
undefined method `replies_path' for #<#<Class:0x007fc519554cf0>:0x007fc5182f7b70>
Did you mean? replys_path
reply_path
I'm bad enough at what I'm doing that I don't know totally what all to describe...
I think part of the problem might be a large confusion between "reply and replys" vs "reply and replies"
maybe.
Here is my tutorial_controller.rb
class TutorialsController < ApplicationController
before_action :authenticate_user!, :except => [:index, :show]
def index
#all_tutorials = Tutorial.all
# #current_user_tuts = current_user.tutorials
# # #current_user_tuts = current_user.tutorials
end
def show
#tutorial = Tutorial.find(params[:id])
#replys = #tutorial.replys
#reply = Reply.new
end
def new
#tutorial = Tutorial.new
end
def edit
#tutorial = Tutorial.find(params[:id])
end
def create
#tutorial = Tutorial.new(create_params)
if #tutorial.save
redirect_to tutorial_path(#tutorial), notice: "Tutorial Created Succesfully."
else
redirect_to :back, flash: "Aw Snap! Error saving Tutorial. Try again Later."
end
end
def create_params
params.require(:tutorial).permit(:title, :body, :user_id)
end
def destroy
#tutorial = Tutorial.find(params[:id])
if #tutorial.delete
redirect_to "/posts/profile", notice: "Tutorial Deleted"
else
redirect_to "/posts/profile", notice: "Error deleting Tutorial, please try again."
end
end
def new_reply
#reply = Reply.new
end
end
And my replys_controller.rb
class ReplysController < ApplicationController
before_action :authenticate_user!, :except => [:index, :show]
def new
#reply = Reply.new
end
def create
#reply = Reply.new(create_params)
if #reply.save
redirect_to :back, notice: "Comment Created Succesfully."
else
redirect_to :back, flash: "Aw Snap! Error saving Comment. Try again Later."
end
end
def create_params
params.require(:reply).permit(:content, :tutorial_id, :user_id)
end
end
and Routes.rb
Rails.application.routes.draw do
devise_for :users
root to: "posts#index"
get "/posts/forum" => "posts#forum"
get "/posts/profile" => "posts#profile"
get "/posts/edit" => "posts#edit"
get "/posts/search" => "posts#search"
get "/tutorials/index" => "tutorials#index"
resources :posts
resources :comments
resources :tutorials
resources :replys
end
and reply.rb (model)
class Reply < ActiveRecord::Base
belongs_to :tutorial
end
and tutorial.rb (model)
class Tutorial < ActiveRecord::Base
belongs_to :user
has_many :replys
end
Sorry for the long post. I was hoping that it would suddenly come to me as I wrote it but it didn't.
I'd really appreciate the time spent on debugging this.
My code is also on github if you want to look at it or fork it or whatever...

And if you have any tips about my code or something I'm doing completely wrong plz tell me...
Thanks a lot for you time....

EDIT:
Here's the output of "rake routes | grep replys"
replys GET /replys(.:format) replys#index
POST /replys(.:format) replys#create
new_reply GET /replys/new(.:format) replys#new
edit_reply GET /replys/:id/edit(.:format) replys#edit
reply GET /replys/:id(.:format) replys#show
PATCH /replys/:id(.:format) replys#update
PUT /replys/:id(.:format) replys#update
DELETE /replys/:id(.:format) replys#destroy

The problem is with you route resources :replys.
Your model name is Reply and its plural is replies so when you create a form with:
simple_form_for #reply
Rails will detect that #reply is a Reply object and try to create a path automatically by pluralizing the name i.e replies_path but you don't have that route, instead you have replys_path so its giving the error.
Though you can explicitly mention the url and change the path to correct one, I would highly suggest you to change the route to resources :replies to avoid this kind of problem in future.
