I get this Error message in my browser
SyntaxError in ProductsController#index

/Users/musdev/work/depot/app/models/product.rb:11: Invalid char `\x1B’
in expression

The code in my product.rb file

class Product < ActiveRecord::Base
validates_presence_of :title, :description, :image_url
validates_numericality_of :price
validate :price_must_be_at_least_a_cent
validates_uniqueness_of :title
validates_format_of :image_url,
:with => %r{.(gif|jpg|png)$}i,
:message => ‘must be URL for GIF, JPG’ +
‘or PNG image.’
eend
def self.find_products_for_sale
find(:all, :order => “title”)
end

def price_must_be_at_least_a_cent
errors.add(:price, ‘should be at least 0.01’) if price.nil? ||
price < 0.01
end

what does this mean? I dont see anything on that line

Regards

Which of those lines is #11? I don’t see immediately any obvious bad
chars in what you posted, but perhaps that’s due in part to the email
processing. Have you tried deleting and retyping that line?

I tried deleting and retyping the line without touching anything else
and now I see this error message in my browser

Seems pretty obvious… @products is nil. That issue is in your
controller.

lol thanks, I was about to take the sucker way out and start over, but
how will I ever learn. I just created a new Product.new object in my
controller and stored it in @products.

Thanks
