Although Radiant CMS supposedly includes an AJAX-y drag-drop support for reordering parent/child relationships, that doesn’t work for me on Radiant’s admin pages, using both Safari and Firefox. So, can I do it by a direct database edit? Without wrecking everything?

The answer is yes. So you don’t have to endure the same heart-stopping suspense that I did when making my first direct edit to re-order page descendancy, all you have to do is change the “parent_id” field in the “pages” table to the id of the desired parents and it’ll work, no problem. Commit the change, refresh the admin interfaces and you’re done.

I love this kind of clean design. The descendancy is noted once, in a human-edited form, and can be changed properly by a simple substitution without horrible side effects, loss of consistency, etc. Good stuff.

1. Install ruby 1.8.4

wget:

http://dev.centos.org/centos/4/testing/x86_64/RPMS/irb-1.8.4-1.c4.x86_64.rpm

http://dev.centos.org/centos/4/testing/x86_64/RPMS/rdoc-1.8.4-1.c4.x86_64.rpm

http://dev.centos.org/centos/4/testing/x86_64/RPMS/ruby-libs-1.8.4-1.c4.x86_64.rpm

http://dev.centos.org/centos/4/testing/x86_64/RPMS/ruby-mode-1.8.4-1.c4.x86_64.rpm

http://dev.centos.org/centos/4/testing/x86_64/RPMS/ruby-tcltk-1.8.4-1.c4.x86_64.rpm

sudo rpm -Uvh –test *.rpm

(no errors? good)

sudo rpm -Uvh *.rpm

ruby 1.8.4 is installed.

2. install ruby gems

No rpm for this, have to use its builtin setup

wget http://rubyforge.org/frs/download.php/11289/rubygems-0.9.0.tgz

tar zvf rubygems-0.9.0.tgz
cd rubygems-0.9.0
sudo ruby setup.rb

3. make sure you have mysql-devel

% rpm -q mysql-devel
mysql-devel-4.1.20-1.RHEL4.1

good …

4. install rails

% sudo gem install rails –include-dependencies
% sudo gem install mysql — –with-mysql-include=/usr/include/mysql –with-mysql-lib=/usr/lib64/mysql –with-mysql-config

select option 2, ruby 2.7

5. That’s it !

I decided to stop complaining about the pluralisation errors in rails and just make a fricking patch. So I did, and was in the process of signing up to submit it when:

Oh dear, DHH. Maybe you should spend some of that temporary Basecamp revenue on, you know, a proper server with more than 1G space? Tell you what, I’ve got an old VPS you can use, it’s got a whole 12G space!

I’ve got a new project, a real world-changing application to finally tie together my interests in fish, sheep, Darkies and last but not least – making a lot of Yen. Let’s see how Ruby on Rails handles creating models for these essential elements of my new Google-Killer!

First up is the sheep – the foundation of any billion-dollar enterprise.

Shadow:/rails/gay_app sho$ ruby script/generate model sheep
      exists  app/models/
      exists  test/unit/
      exists  test/fixtures/
      create  app/models/sheep.rb
      create  test/unit/sheep_test.rb
      create  test/fixtures/sheep.yml
      create  db/migrate
      create  db/migrate/001_create_sheep.rb

Well done. As expected, Rails is sheep-aware. Of course it is – who can do anything these days without sheep? And the first database ever written was created to keep track of sheep. So no surprises there, moving right along to another essential ingredient in any recipe for global domination, fish:

Shadow:/rails/gay_app sho$ ruby script/generate model fish
      exists  app/models/
      exists  test/unit/
      exists  test/fixtures/
      create  app/models/fish.rb
      create  test/unit/fish_test.rb
      create  test/fixtures/fish.yml
      exists  db/migrate
      create  db/migrate/002_create_fish.rb

Again, no surprises. Fish are second only to sheep as lynchpins of the world’s business ecosystem, and frankly, any web framework unable to correctly track fish resources has failed before it’s even begun. But now, let’s see how Rails handles the slippery problem of Darkies:

Shadow:/rails/gay_app sho$ ruby script/generate model darky
      exists  app/models/
      exists  test/unit/
      exists  test/fixtures/
      create  app/models/darky.rb
      create  test/unit/darky_test.rb
      create  test/fixtures/darkies.yml
      exists  db/migrate
      create  db/migrate/003_create_darkies.rb

Surprise! I had expected Darkies to throw Rails for a loop; seems like DHH deserves much more credit than I gave him. He’s obviously a man of the world, well up to speed on Darky-tracking requirements; I wouldn’t be at all surprised, bearing this advanced capability in mind, if DHH isn’t using Rails to track his own private Darky supplies.

But now to the most important table in this database: how to track all the money this groundbreaking app will, without a shred of doubt, pull in by the truckload?

Shadow:/rails/gay_app sho$ ruby script/generate model yen
      exists  app/models/
      exists  test/unit/
      exists  test/fixtures/
      create  app/models/yen.rb
      create  test/unit/yen_test.rb
      create  test/fixtures/yens.yml
      exists  db/migrate
      create  db/migrate/004_create_yens.rb

Oh dear. Seems like Rails isn’t the internationally-minded upstanding citizen of the world I had always thought it was. “Yens”, DHH? Why don’t you go down to the bank and ask for some “yens”? You can have all the fish, sheep and darkies you want, but at the end of the day if the best you can do is “yens”, it’s time to go back to Denmark, David Heinemeier Hansson, you racist motherfucker!

UPDATE: DHH .

Since it took me a couple of minutes to correctly apply the Rails icon to this folder (I’m a perfectionist for such useless things), I thought I’d upload a zipped version for anyone else who obsesses over their folder icons.

Enjoy:

UPDATE: Speaking of Rails, let’s ask the genius DHH what the plural of “staff” is, shall we?

Shadow:/rails/wwp sho$ ruby script/generate model Staff
      exists  app/models/
      exists  test/unit/
      exists  test/fixtures/
      create  app/models/staff.rb
      create  test/unit/staff_test.rb
      create  test/fixtures/staffs.yml
      create  db/migrate/006_create_staffs.rb

How about that! The plural of “staff” is staffs.
