Rake Abort Error with no answer other than head to the wall . Repeat if necessary.

Question

I am the intrepid little programmer that could. I began programming rails five weeks ago and I have been stuck on the same error for that entire time. It goes like this. I have mysql application installed, have the latest rails (2.3.5), ruby (1.8.6), and mysql (5.1.40).

I created a perfectly beautiful database and table with content in rails several times, same thing just to make sure. It's there. It works.

Then I go into my database.yml and make sure my login/password root access database is mysql everything good. Green light.

Then I do a rake db:migrate..

and I get this

    rake aborted!
    undefined method `generate_best_match=' for ActionController::Routing:Module

And seriously, no deals..

For five weeks..

What is a dude to do? Thanks!

Answer 1

Is this relevant? Re: Deploying Error: undefined method 'generate_best_match='

Answer 2

Try commenting out the line:

ActionController::Routing.generate_best_match = false

in config/initializers/new_rails_defaults.rb

You lose some routing changes introduced in 2.3.4, but at least it might get your app running.

Answer 3

This error is caused by not using the correct mySQL version. In my case, 32-bit. Once I installed the 32-bit mySQL, and used the 32-bit gem, this worked perfectly.
