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.''
end
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
