hello..
I am new to Ruby on Rails.. (2.2)
I am currently following steps from the book "agile web delopment with
Rails" building depot application.
It says I need to edit "app/models/product.rb" file and add the
following lines to check the price to be at least a cent.. that''s 0.01
----
def price_must_be_at_least_a_cent
errors.add(:price, ''should be at least 0.01'' ) if
price.nil? ||
price < 0.01
end
----
after this, I typed 0.1 and 0.10, and get the error.. saying "should
be at least 0.01"..
if I type 1, or 0.01.. I don''t get the error.
am I the only one with this problem? if so, i''d like to know what I
need to do to fix the problem.
thanks

i just tried it for myself. it''s working correctly. so i advice to put a debugger at the beginning of your action and look what you are getting for price and where the error occurrs (whether it''s inside that method or even before). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

thank you for trying it out for me.. and for the advice too.. I ran over the steps again.. and it works fine now.. I found out why too.. when I added a new column "price" to the table.. I forgot to write its :precesion and :scale .. I hope I don''t make mistakes like that no more.. thank u MaD On Feb 14, 11:55 pm, MaD <mayer.domi...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> i just tried it for myself. it''s working correctly. so i advice to put > a debugger at the beginning of your action and look what you are > getting for price and where the error occurrs (whether it''s inside > that method or even before).--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
