NoMethodError in Products#create - ruby-on-rails

Question

I am totally new to programming and I am having trouble. About 10 days ago I started the UT-Rails course on ureddit.com hosted by Richard Schneeman. So far it has been going very well, but I am on week 5 and having trouble. You'll have to excuse me if I don't use the right terminology, as it has been a lot to take in.
https://github.com/zkay/move_logic_to_controllers is the tutorial I am following at the moment.
I am up to step 2. I have replaced the text in app/views/products/new.html.erb with the following:
<%= form_for(#product) do |f| %>
<div class="field">
<%= f.label :name %><br />
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :price %><br />
<%= f.text_field :price %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
However, when I try to add a new product per the tutorial, the rejection I get back is:
NoMethodError in Products#create
Showing C:/Sites/move_logic_to_controllers/app/views/products/create.html.erb where line #3 raised:
undefined method `name' for nil:NilClass
Extracted source (around line #3):
1: <h2>Product Created Successfully<h2>
2:
3: <%= #product.name %> added to the website, it costs: $<%= #product.price %>
Rails.root: C:/Sites/move_logic_to_controllers
If I remove the .name and .price calls the page works, but it doesn't display any of the data I submitted.
In app/controllers/product_controller.rb I have the following:
class ProductsController < ApplicationController
def index
#products = Product.includes(:user).all
end
def new
#product = Product.new
end
respond_to do |format|
if #product.save
format.html { render :action => "create" }
format.json { render :json => #product }
else
format.html { render :action => "new" }
format.json { render :json => #product.errors, :status => :unprocessable_entity }
end
end
end
Sorry if this is long winded. I appreciate any help.

Answer 1

it should be <%= #products.name %>

Answer 2

/app/views/products/create.html.erb
You don't want to use create.html.erb.
class ProductsController < ApplicationController
def index
#products = Product.includes(:user).all
end
def new
#product = Product.new
end
def create
#product = Product.new(params[:product])
if #product.save
redirect_to products_path, notice: "You added product"
else
flash[:error] = "Something wrong!"
render :new
end
end
end
If you use Rails 4 use:
def create
#product = Product.new(product_params)
if #product.save
redirect_to products_path, notice: "You added product"
else
flash[:error] = "Something wrong!"
render :new
end
end
private
def product_params
params.require(:product).permit(:name, :price)
end
