Rails 3 / RSpec 2 use_transactional_fixtures and after_commit

[dubstep]

We’re migrating a Rails 2.3.x application to Rails 3 and RSpec 2.x.
In Rails 2.3.x we were using
https://github.com/freelancing-god/after_commit to provide
after_commit functionality (now provided by Rails 3).

The plugin version of after_commit came with some helpers to make
testing with use_transactional_fixtures = true work.

From: https://github.com/freelancing-god/after_commit

“Keep in mind that transactions are finicky at best in tests, and so
there’s a helper module to make after_commit play nicely in your
testing context. You’ll need to add these two lines to your spec/test
helper:”

ActiveRecord::Base.send(:include, AfterCommit::AfterSavepoint)
ActiveRecord::Base.include_after_savepoint_extensions

Anyone else ran into this?

Best,
Michael G.

We’re just running into it now, but we’re using after_commit in Rails 3
for
the first time. The callback appears not to fire in our specs – I
noticed
your posting but have not had luck getting the gem to load. Bundler
1.0.7
requires the gem, and it generates this:

/Users/kurtsnyder/.rvm/gems/[email protected]/gems/after_commit-1.0.7/lib/after_commit/active_record.rb:15:in
include_after_commit_extensions': undefined methodsubclasses_of’ for
Object:Class (NoMethodError)
from
/Users/kurtsnyder/.rvm/gems/[email protected]/gems/after_commit-1.0.7/lib/after_commit.rb:81

Did you add these two lines to your spec_helper.rb file or somewhere
else?

ActiveRecord::Base.send(:include, AfterCommit::AfterSavepoint)
ActiveRecord::Base.include_after_savepoint_extensions

I’d be interested in helping to get this to work, but not sure where to
start as we’re new to after_commit.

after_commit is built-in to Rails 3, so you don’t need the gem. Rails
3 does not include any type of AfterSavepoint helper for running with
transactional fixtures turned on. That is the piece that needs to be
ported over to Rails 3.

Thanks – that confirms the results of our experiments.

Hi guys,

Just wanted to let you know that I had the same problem and ended up
writing a monkey-patch for it:

Pretty straightforward, fairly clean as monkey patches go, if I may.
