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

NoMethodError in Products#index

Showing app/views/products/index.html.erb where line #6 raised:

You have a nil object when you didn’t expect it!  
You might have expected an instance of Array.  
The error occurred while evaluating nil.each

Extracted source (around line #6):
