Another tip for myself, courtesy of a co-worker.

If you want to run a rails console on a remote app you can use the `ssh -t` option. The -t option forces pseudo terminal allocation. Put your pubkey on the remote system to avoid password prompts.

ssh -t username@some_server 'cd /remote/rails/app/base/directory && bundle exec rails c production' ( Read more... )

We've pretty much reached the conclusion that ActiveRecord::Base.all, or .find(:all) if you prefer, should never be used without conditionals. If you want to iterate over every record in the table, you should use my custom .foreach method ( Read more... )

Little did I know that ActiveRecord doesn't have a truly iterative way for dealing with results. You get the find method, with its various incantations of :all, :first, :limit, etc, but there's not way to iterate over every record in turn without slurping the result set into memory first ( Read more... )

I recently ran into some frustrating behavior with PostgreSQL 8.3.4 on Linux with a RoR app. I could create a database, I could could connect to it from the command line or even with script/console. However, when I tried to run the app via Phusion Passenger I was getting this error:

/!\ FAILSAFE /!\ Tue Apr 06 23:19:47 +0000 2010 ( Read more... )

So, I'm doing RoR work again, and I'm hitting those annoying little issues that bugged me the first time around.

Today, it's the fact that I have to setup separate validations to handle nils/blanks. IMO I should be able to do this:

validates_numericality_of :elevation, :allow_nil => false

Now, this works. It validates that elevation is a number ( Read more... )

My copy, my beta copy, of Programming Rails 3rd edition, is already obsolete.

In other news I ran "Rails" + "Merb" through some anagram finders, since I thought a new name (or at least a code name) would be in order for Rails 3. Here were a few of my favorites:

* Rare Limbs
* Ramble Sir
* Real Brims
* Marble Sir
* Barr Slime

Yesterday I spent about an hour tracking down this bizarro bug I had seen occasionally in the logs but hadn't figured out:

TypeError (singleton can't be dumped):
C:/ruby/lib/ruby/gems/1.8/gems/actionpack-2.1.2/lib/action_controller/session/active_record_store.rb:82:in `dump'
I was finally able to reproduce this consistently. It seemed if a new ( Read more... )

I have to say that this post is the most vapid blog entry I've seen from DHH yet. So, now we can replace 'end_form_tag' with just 'end'.

Wow. Thrilling. I wonder what's on TV right now. I can't wait to start yoga next year.

Wake me up when they add support for bind parameters in the Oracle adapter.

I'm back to working on $RAILS_APP full time again. I think my HTML/CSS skills have finally reached the point where I can design a layout that doesn't suck. They're not great, mind you, but at least I don't want to gouge my eyes out any more ( Read more... )

If I waste another minute because I accidentally wrote "belongs_to :users" instead of "belongs to :user" I'm going to scream. GAH!

I'm not sold on the whole pluralization thing. I know my table names, so just let me use them as-is, dammit!

Yes, yes, I know you can configure this, blah, blah. Hey, it's my blog and I'll whine if I want to!
