How to freeze to 2.1.0-RC1?


What TAG or REVISION number do I use to rake rails:freeze:edge to 
2.1.0-RC1? I've tried TAG=rel_2-1-0-RC1 and TAG=rel_2-0-991, but without 
success.

(I'm on shared hosting, so I can't just gem install rails easily.)

Also, when I freeze without a parameter (= bleeding edge if I understand 
correctly) and specify RAILS_GEM_VERSION='2.0.991' in environment.rb, it 
seems to recognize the 2.1.0 features, but "rails -v" and "ruby 
script/about" still say "Rails version 2.0.2". Is that normal?

attachment_fu, how would you test this?


Hi, i'm starting to go nuts because of this. i'm playing with
attachment_fu, everything is ok, but i also want to put everything under
test too. Actually i've a post, where you can upload images, and it
works. But now i want to set that it's mandatory to upload at least 1
image.
The code it's quite simple and stupid:

errors.add(:image, 'at least one') if post.images.size.zero?

...and obviously it works...

...but how would you test this by unit tests?

Select and how to read the api


I'm trying to understand how to use the select, especially how to make
an option selected. I want to add the values manually, but be sure one
value is selected when finding an existing post in the db.

How are you supposed to understand how to do that from this?

http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#M000940

This is what I've used until now:

<%= select 'user', 'age',
['','10-20','20-30','30-40','40-50','50-60','60-70','70+']  %>

two database migration (active record)


Hello.

I want to write script, that will migrate one database (with models) to
another database (with another models) using ActiveRecord and all of its
benefits. It is possible? Please give me any tips.

I am moving database form old app to new one. It would be great to use
ActiveRecord for this complex task.

Thank you.

Generator simple question: How to specify parameter?


I wonder if I have did something fishy here (probably I did...)
when I type:

script/generate scaffold model --skip_migration

It saids:
invalid option: --skip_migration

Perhaps some syntax I don't know on how to specify parameters for a
generator?

Timeout not obeyed when trying to open bad url


Here is something Ive never seen before:

I have a list of urls fed into mechanize (which uses net/http to grab
pages)

I have it setup as thus:
require 'mechanize'
  agent = WWW::Mechanize.new;
  error_count = 0
  begin
    Timeout::timeout(2) {
      @tracked_page = agent.get("http://#{site_url}")
    }
  rescue Timeout::Error => timeout_error
    puts "I TIMED OUT AFTER 2 SECS BUT IM TRYING AGAIN:
#{timeout_error}"
    error_count += 1
    if error_count < 5
      puts "ATTEMPT NUMBER #{@error_count} QUITTING AFTER 4 TRIES"
      retry
    end
end

This is all well and good, it works fine and catches any timeout
exceptions, except when its trying to deal with one particular URL
(www.webdevking.com).

This URL is not currently resolving to any host. it returns "unknown
host" when you try to connect to it.

auto url formatting?


Hello!

I'm having a bear finding this, so I thought I'd just ask...

If I want to capture "website" as a user field (i.e. in a contacts
database)... is there an easy, automatic way to properly format it for
a link_to tag regardless of whether they include the "http" or not?
I.e. some helper or something that someone has that I could do
something like:

<%= link_to @user.website, format_url(@user.website) %>

And it would turn:

"www.google.com" # => "http://www.google.com/"

but also:

"http://www.google.com" # => "http://www.google.com/"

and:

"ftp://ftp.google.com" # => "ftp://ftp.google.com/"

I imagine there are some code snippits for doing this... I just
haven't found one yet.

Thanks!
