rails 3.1rc4, Engine rather broken

rubyonrails-core

Hi there.

I'm having some real issues with engines and rc4:

1: generators are broke

rails plugin new myengine --mounable cd myengine rails g <broken>...

2: after you build an engine and gem it up, if you do:

rails new myproject add gem 'myengine' to Gemfile add mount MyEngine::Engine => '/myengine' rake routes:

myengine /myengine {:to=>MyEngine::Engine}

then rails s

visit http://localhost:3000/myengine

error log:

Started GET "/myengine" for 127.0.0.1 at Thu Jul 07 16:07:11 +0100 2011 ActionController::RoutingError (No route matches [GET] "/myengine"):

This is really odd, as rails 3.0 engines worked just fine on rails3.0, however my namedspaced rails3.1 engine wont (and cant run on 3.0 as isolate namespace is 3.1 only)

What can I do. Currently setting to edge-rails gets bundle failures on actionpack (3.2.0.beta) etc...

Thanks

Perhaps the issue is related to passing “mounable” instead of “mountable”:

rails plugin new myengine --mountable

Hi!

Can you please confirm and fill this issues in a bug report?. With the latest edge code I don't get that ...

yeah, I routed the engine in the main application routes as follows:

mount MyEngine::Engine => '/myengine'

and rake routes shows it as mounted as expected, it just doesnt actually let you access it when running the server.

ok so it's working (to a degree on edge rails):

all the build, install etc work as expected (even generators within the engine folder).

however, the following does not work when in the app I want to mount:

rake railties:install:migrations

it doesn't copy the migrations over from the engine into the app, just does nothing silently.

Do I need to add something to the engine to expose them??

Thanks

I had a similar problem. After some amazement the problem was in the gemspec file. The config directory was not added with the gem and therefore the routes are not loaded. Maybe adding Dir["congi/**/*"] to myengine.gemspec will solve your problem.
