JRuby 1.6.3 and Rails 3.1rc5 and activerecord-3.1.

I am able to create able to run my migrations from JRuby 1.6.3 and Rails 3.1rc5 and in a console session create a simple Role object like this:

jruby-1.6.3 :001 > role = Role.new(:name => "Admin")
   (1.0ms)   SELECT name
 FROM sqlite_master
 WHERE type = 'table' AND NOT name = 'sqlite_sequence'

 => #<Role id: nil, name: "Admin", created_at: nil, updated_at: nil>

All is good but when I run

Role.destroy_all

I get the following stack trace:

jruby-1.6.3 :003 > Role.destroy_all
ArgumentError: wrong number of arguments (3 for 2)

It would seem all is not right between activerecord-3.1.0.rc5 and jruby.

Anybody any help on this?

回答1:

You are correct. All is not right yet with activerecord-jdbc-adapter and Rails 3.1. I'm working on it and hope to have it ready by the time Rails 3.1 goes final.

回答2:

There has been some progress on the activerecord-jdbc-adapter front and you can now get your setup working now by using the master branch of activerecord-jdbc-adapter. Just add the following to your Gemfile:

gem 'activerecord-jdbc-adapter', :git => 'https://github.com/nicksieger/activerecord-jdbc-adapter.git

I'd only recommend doing this if you cannot wait for the final activerecord-jdbc-adapter gem and certainly not in production.

回答3:

Don't you have to specify conditions for it destroy_all?

e.g.
