As far as I can see there is an extra ',' (comma) at the end of the first
statement, the statement just before your validates_numericality_of. I have
indicated that below within *[]*. Removing that should solve your issue.
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 a URL for GIF, JPG' + 'or
PNG image'
protected
def price_must_be_at_least_a_cent
errors.add(:price, 'should be at least 0.01') if price.nil? ||
price < 0.01
end
end
Thanks & Regards,
Dhruva Sagar.
