Hello,

I’ve been playing with this for hours, and got through a couple glitches  
(e.g. updating to Ruby 1.8.4) but this one is well beyond my N00b  
skills. When trying to run script/server I get:

./script/…/config/…/vendor/rails/activesupport/lib/active\_support/dependencies.rb:87:in  
`as_load_path': stack level too deep (SystemStackError) from ./script/../config/../vendor/rails/activesupport/lib/active_support/dependencies.rb:106:in`const\_missing’

from  
./script/…/config/…/vendor/rails/railties/lib/commands/server.rb:28  
from script/server:3

Can anyone point me in the right direction to get this working? Look  
forward to seeing your responses tomorrow - I gotta get to bed!

Did you include the line

Engines.config :edge, true

before any of the engine configuration in environment.rb? If you  
update your copy of the engines plugin, the README should now be a lot  
clearer.

Thanks James,

That got me past that issue. Now I am having another. I found a couple  
references to it in this forum but they all basically point me back to  
the instructions in the link you gave. Any idea why this problem is  
occurring?

Yep. Here is my environment.rb config code:

#############################

# Include your application configuration below

Engines.config :edge, true

module LoginEngine  
config :salt, “mysalt”  
config :app\_name, “my\_app\_name”  
config :confirm\_account, false  
end

ActiveSupport::CoreExtensions::Time::Conversions::DATE\_FORMATS.update(:my\_format  
=\> ‘%a %m/%d/%y %l:%M %p’)  
ActiveSupport::CoreExtensions:📅:Conversions::DATE\_FORMATS.update(:my\_format  
=\> ‘%m/%d/%y’)

Engines.start :login

#############################

I am reading through the README, but so far nothing is jumping out. rake  
tasks for the Engines plugin are failing as well, such as:

Thanks to James, I got this running. Basically, he figured out that you  
have to put the following at the very TOP of your environment.rb:

module Engines  
CONFIG = {:edge =\> true}  
end

He is going to update the README as well.

Thanks James!

A week later I am still struggling with this (OK, well I didn’t really  
play with it all week)… My first problem is I am new to OS X, and  
weird things keep happening like mysql, ruby gems, and other things lose  
their “bindings” (at least that’s what I think is happening) and I have  
to re-install things. But that’s another story.

So anyway, I got everything re-installed, got my project back to a  
working state, pre-Edge Rails. Then I started to slowly update again.  
Added the svn:external for edge rails and the engines trunk (my app uses  
login\_engine). I updated the dispatch.\* files, and added the

module Engines  
CONFIG = {:edge =\> true}  
end

to the top of my environment.rb. WEBrick boots up fine, but I get the  
following in my browser:

NoMethodError in #

Does anyone have any idea what I’m missing?
