And then a light … “I upgraded postgresql recently!”

Just reinstall the postgres gem and you are done…

With a great surprise, that didn’t worked so we started trying all possible apache configuration combinations to avoid that 404 error that was becoming a nightmare.

After few hours we started doubting about our Apache knowledge and even about our capacity of reading and following a couple of stupid instructions on a website!

We gave up and we started googling around when… the solution came out from dozens of blogs, forums and newsletters:

MOD_RAILS IS NOT COMPATIBLE WITH RAILS 2.2.2 AND ITS NEW ROUTING SYSTEM

“HOLY CRAP” was our esclamation and I will not mention here all the italian’s bad words that suddenly came out from our mounth!

So, here the solution: put this line here
config.action_controller.relative_url_root = "/guestbook"
in your environment.rb

Now restart apache and enjoy!

ps. why hadn’t we changed mod_rails with mongrel or anything different? I don’t know!!!!

We started from the database design (not exactly the rails way) and we are trying to solve problems that a Rails developer usually doesn’t have like create the scaffold without migration scripts!

Here are 3 simple steps to do it:

  • rake db:schema:dump (create the schema dump from the existing database)
  • mv db/schema.rb db/migrate/001_initial.rb (create the initial migration script manually)
  • script/generate scaffold firstmodule field1:text field2:varchar field3:date –skip-migration

The most important thing you should never forget is that your tables on the database must have a PLURAL name but use the SINGULAR name when you create the scaffold for that table.
 ( ex: the table name is “tools” but the command to create the scaffold is script/generate scaffold tool )

Happy RoRing !!!
