My web-form for creating a Game allows the user to pick the four contents (as c_type_#). I'm therefore able to populate the Piles at creation of the Game. However, I can't fig...
I am creating a blog in Rails using the Scaffold feature. I would like to add a 'tags' field to each post like on StackOverflow and Wordpress. I can do this with a string type ( scaffold post title:string body:text tags:string ) and then comment seperated but this isn't a good practice, since I also want the reader to be able to browse b...

I've inherited a rails site that I need to deploy (quickly!) to our webhost, which is a standard *nix shared server that uses FastCGI for rails apps. I've worked with rails sites on multiple occasions in the past but wouldn't consider myself an expert by any stretch. This particular app was developed using capistrano, with which I've g...

I've got a method in my user class currently to get the "home" URL for each user: class User def home_url "~#{self.username}" # How I'd like to do it for subdomains: #"http://#{se...
This is what I still don't understand (but probably should)... if I run this command: script/generate scaffold FooFoo name:string submitted_on:datetime How do I link to a the page that lets you view the list of FooFoo? This doesn't seem to work, and every variant of it that I've tried doesn't work either: <%= link_to "Mylink", foo_fo...

I have several Rails models that I'm trying to expose via a REST api. I'm looking for a simple way to allow mass assignment in certain contexts (through the api or admin interface) but to disallow when populating from user based forms. There are a few catches as well. First, I'm populating a bunch of child objects using accepts_neste...
This is a very basic question with probably an easy answer. Let's say I have a model called Product. When I add map.resources :products to my routes.rb I have access to some default paths new_product_path, edit_product_path and so on. As I understand this should be used when linking to a resource e.g. using the link_to helper method:...

I g...

Hi I am having what seems like a very simple problem. I just can't seem to pin down what I need to do. I have a birth_date that is in the Date format.
