Undefined method `accept' for nil:NilClass

I’ve upgraded to rails 3.2.
I’m using jruby-1.6.5.
When I run db:migrate rake abort with message “undefined method
`accept’ for nil:NilClass”.
I had not that problem with jruby-1.6.5 and rails 3.1.
I’ve submited the bug to jira.

It seems so strange to me that none has reported to have the same
problem after upgrade to rails 3.2.

I am getting the same error, and I am using a SQLite database.

that’s the trace:

I’m getting the error on Ubuntu when running an Oracle query. MRI Ruby
1.9.3-p0

Opened an issue in the rails github
https://github.com/rails/rails/issues/4632

Hi.

We have a JIRA ticket now: https://jira.codehaus.org/browse/JRUBY-6363

This is most likely a JRuby issue (and much less likely JDBC
adapter/Rails issue).

I was able to FIX the issue by getting the latest mysql2 gem. In my gem
file, I has a specific older vesion and removing the version and
updating the bundle resolved the issue.

Here’s the closing comment from GitHub:
https://github.com/rails/rails/issues/4632

Same case using ruby-oci8(v2.1.0) along with oracle_enhanced(v1.4.0)
adapters. It worked with Rails 3.1. Neither console nor rake work. I
guess the problem is from oracle_enhanced adapter because the ruby-oci8
worked (OCI8.new …).

I’m using postgres and I’ve still the issue.

I have to uninstall rails v3.2 and install rails 3.1 to make my app
work. Thanks!

After upgrading activerecord-oracle_enhanced-adapter to 1.4.1, it is now
working for me against both MySQL and Oracle from Rails 3.2.1 and MRI
Ruby 1.9.3-p0.

Thank you Raimonds Simanovskis & Edgars Beigarts!

I’ve done the same, but I hope the bug is resolved soon.

As a follow-up to this in case someone comes across this thread (as I
did), this was a AR-JDBC issue that’s now fixed.

$ bundle update activerecord-jdbc-adapter

fixes the problem for me.

Sébastien.
