I am getting the same error than you.
Did you find a solution ?

Seb

since everybody seems to get it up and running, I must miss something important here … I followed the steps in the tutorial, but after entering the first post, I get the following error from the Action Controller:

post_url failed to generate from {:controller=>”posts”, :action=>”show”, :id=>#<Post id: #, title: “MyFirstPost”, body: “This is my first post”, created_at: “2009-11-12 11:04:04″, updated_at: “2009-11-12 11:04:04″>}, expected: {:controller=>”posts”, :action=>”show”}, diff: {:id=>#<Post id: #, title: “MyFirstPost”, body: “This is my first post”, created_at: “2009-11-12 11:04:04″, updated_at: “2009-11-12 11:04:04″>}

Extracted source (around line #13):

10:
11:
12:
13:
14:
15: ‘Are you sure?’, :method => :delete %>
16:

Can anybody help me getting started?

Thanks,

Michael

Еssentially, with this new version of activerecord-jdbc, you don’t need to modify the database.yml anymore, but you need to run one additional command: jruby script/generate jdbc

(in /data/home/haluk/dev/myapp)
rake aborted!
The driver encountered an error: com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: Unknown database ‘myapp_development’

(See full trace by running task with –trace)

jruby -S rake db:create:all does not create db but why ?

my db config:
development:
adapter: jdbcmysql
encoding: utf8
database: myapp_development
username: root
password: xxxx

I can enter mysql server using username: root an passwort: xxxx.
(mysql -u root -p)

activerecord-jdbcmysql-adapte is installed aswell
jdbc-mysql-5.0.4 activerecord-jdbc-adapter-0.9.2

I’m using jruby-1.4.0RC1 and rails version 2.2

jruby getting started 따라하다 삽질 좀 했다. 일단 database.yml 설정을 jdbcmysql 으로 바꿔야 하는 부분이 빠져있고, 시냅틱으로 설치한 mysql의 charset 설정을 바꿔주는부분을 찾느라 대굴대굴. 정답은 …

Will JRUBY works better than RUBY-1.9 ?.

Já viu este framework??? é o JRuby on Rails, deve ser bom….
