Question

Hello
I am currently using:

• Ubuntu 10.04LTS
• Netbeans 6.9.1 (with embedded JRuby 1.5.1)
• JDK6u17
• GlassFish Gem 1.0.2

I am using a old JDK because of this bug:
http://jira.codehaus.org/browse/JRUBY-4785

I have partially completed application, but i want migrate to rails 3(currently application is in rails 2.3.8).

So i go to:
$HOME/netbeans-6.9.1/ruby/jruby-1.5.1/bin and type: jruby gem install rails -v=3.0.3. Everything is OK.

Then i create a sample RoR project and use some simple scaffold. Works.

But when i choose in Netbeans rake db:migrate it shows me message: "db:migrate" taks does not exist.

Any idea how to fix that?

I would be grateful for the help.

UPDATE

I have tested this in Ubuntu and it works fine.
But in Mac OS X this trick don’t work.
So I made a symbolic link called jrake to jruby/bin/rake

cd /bin
ln -s /Applications/NetBeans/NetBeans\ 6.9.1.app/Contents/Resources/NetBeans/ruby/jruby-1.5.1/bin/rake jrake

and I just type jrake db:migrate in project Directory and it works.

UPDATE

Link broken – From the Google Cache of Blake Simpson’s blog:

I have recently reinstalled Ruby on Rails 3.0.0 and created a new
Rails project in NetBeans 9.6.1

I could not migrate my database, or any other rake tasks for that
matter. I kept getting the error:

 "db:migrate" task does not exist

The solution is to right click your project select “Run/Debug Rake
Task” and then click the button titled “Refresh Tasks”.

Once this is done you should see a list of all your rake tasks. After
this you can simply re-run the db:migrate task and it will work.
