Getting Started with Rails guide - getting errors in step 5.12 Using partials

After changing the edit and new forms to use the _form partial, I get this error on trying to edit a record (I changed article to artwork for the examples):

No route matches [POST] “/artworks/2/edit”
Rails.root: c:/Users/bburns/Desktop/arttour

“artwork”=>{“artist”=>“inness”,
“year”=>“1889”,
“title”=>“moonrise”,
“about”=>""},
“commit”=>“Save Artwork”}
And adding a new record gets a similar error -

No route matches [POST] "/artworks/new"

I’m new to Rails so not sure what might be going wrong - thanks in advance for any pointers

routes.rb:

Rails.application.routes.draw do
get ‘welcome/index’
resources :artworks
root ‘welcome#index’
end

artworks_controller.rb:

class ArtworksController < ApplicationController

def index
@artworks = Artwork.all
end

def show
@artwork = Artwork.find(params[:id])
end

def new
@artwork = Artwork.new
end

def edit
@artwork = Artwork.find(params[:id])
end

def create
@artwork = Artwork.new(artwork_params)
if @artwork.save
redirect_to @artwork
else
render ‘new’
end
end

def update
@artwork = Artwork.find(params[:id])
if @artwork.update(artwork_params)
redirect_to @artwork
else
render ‘edit’
end
end

private
def artwork_params
params.require(:artwork).permit(:artist, :title, :year, :about)
end

end

edit.html.erb:

Editing artwork

<%= render 'form' %> <%= link_to 'Back', artworks_path %>

_form.html.erb:

I think that should be form_for @artwork

Hi I am also doing this tutorial but go stuck on 5.12 Using Partials.
I kept getting a message saying that the template was missing, but it wasn’t.
It kept looking for _form instead of _form.html.erb, not sure why. So to get it working I had to change the file to _form, this doesn’t seem correct. I have checked all the code and all is correct, to make sure I copied the code from the web page to eradicate any typos.
I did carry on with the tutorial which I have know finished, but this is still bugging be for future refernce.
