Hi, I''m looking for a way to extend one of my models to allow some level of abstraction between what goes into it and how it is stored. For example, say I have a Product and I want to set it''s price. A person using the website will type the price in euros. Internally, I''d like to store the price as an integer value of cents. I can currently do this with some ugly code

i just found out i can pass mutiple parameters from views like <%= link_to doctype.name, :action => "show_towns", :id => doctype.name, :id2 => doctype.id%> silly me, i always had the impression that i could only pass 1. i guess i dont have to use sessions after all for my site. is there anything wrong with this? basically instead of the user filling out

Hi, I''m having a weird validation issue. Validation isn''t working for certain attributes and, for some reason, it''s also affecting things outside of validation. For campers on certain camp types, we require some information about their school. I tried to validate the information this way: validates_presence_of :school_type, :if => Proc.new { |c| !c.booking.nil?

I have a form where I dynamically add form elements based on user input. An example is that when a user selects a "server" from a select box I add (via AJAX calls back to server) a "type" select box pre-populated with valid choices for that server. I do this by using observe_field on the "server" field and update a div on the page with the new "type"

Hi, I''m developing a Rails app which uses dynamic forms. To implement these, I''ve used AJAX and Rails''s built-in form observers. Unfortunately, I''m having a problem. This is how the form starts: * Country select box [OBSERVED] (Republic of Ireland selected) * County select box [OBSERVED] (none selected, list of Republic of Irish counties in the drop down)

hello, i am having trouble on how to implement this. i have a table of doctor information where each doctor has a town and county field. i would like to create a view that shows the amount of doctor_types in each town.

Today, I had a tragic hard drive crash. I hadn''t updated anything to SVN in two weeks. I''m posting this here as a reminder to my beloved Rails community. Everyone, right now..... make a backup of your rails work. Make sure its on two disks. Many of you already do that automatically, but just make sure its working. Two near-release rails plugins were lost in the tragic crash

I''m new to Ruby and RoR but excited to learn what I can do with RoR; I have Pickaxe second edition and want to get "Agile Web Development with Rails" but I''m aware that the book was published some while before RoR version 1.0 was released. Has a lot changed since then, and would I therefore be advised to wait for a second edition of AWDwR? Many thanks in advance

Hi, I''m having a lot of problems while integrating the salted login generator. All of the errors are of the form: "The error occured while evaluating nil.[]" Most seem to be down to evaluating a nested hash, where the first hash is a nil object. For example, @params[''user''][''login''] where @params[''user''] returns the nil
