Mongrel under Rails 3 beta 3

I'm experiencing the exact same problem, and it's really annoying.

Can you confirm if this problem still exists on Rails 3 Beta 4?

It might be that Mongrel doesn't support Rails 3 yet. But please do try and confirm if this issue still exists on Rails 3 Beta 4.

Same on Rails 3.0.0.beta4 (and Rails 2.3.8 as well)

Same thing here:
rails3.0.0,
mongrel 1.1.5

But using the rails server command:

I get the same error message.

After I have added gem 'dispatcher' to the Gemfile the mongrel_cluster starts without an error.

But it does not serve any request:

Try adding gem 'mongrel' to your Gemfile and running rails server instead of mongrel_rails, and tell us what your results are. Seems to work just fine for me. I think mongrel_rails was created for Rails 2, and not Rails 3.

This is what I tested it with:

› ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10.5.0]
› rails -v
Rails 3.0.0
› gem spec mongrel | ruby -ryaml -rubygems -e "puts YAML.load(STDIN).version.to_s"
1.1.5

These are the complete steps to reproduce what I did (assuming ruby is installed):

› gem install rails
› rails new Rails3TestApp
› cd Rails3TestApp
› echo "gem 'mongrel'" > Gemfile
› bundle install
› rails generate scaffold foo bar:string
› rake db:migrate
› rails server # Then go to localhost:3000/foos in your browser.

Hope this helps.

Oops, that echo line should be echo "gem 'mongrel'" >> Gemfile. Otherwise it would overwrite the entire file.

Hendrik,

you are right. mongrel with script/rails s mongrel works perfect.

Seems to be, that mongrel_rails does not work with Rails 3. That's very bad, because many people use mongrel cluster on production.

But it's not an Rails problem.

Can any rails dev close that bug?

Thanks
