Yet another engines not working with edge

surendra_s · March 20, 2006, 2:41pm

Hello,
Recently something changed with edge, such that engines are no longer
working with edge rails, in spite of the line

Engines.config :edge, true

in the environment.rb

Also, on cursory analysis this stack trace seems different from earlier
stack
traces.

Thanks.

I’ve recently commited a new version of trunk that works with the
current edge:

http://dev.rails-engines.org/repository/changesets/305

Please try that and let us know how you fare.

I am on rails revision 4006 and engines revision 309.
The backtrace is different this time:

I was wrestling with this last night and I think I found a solution.
Apparently one of the recent edge rail changes moves the Rails::VERSION
constant somewhere else. There are a couple of checks that look like
this in the code…

if Rails::VERSION::STRING = “1.0.0” && !Engine.config(:edge)

The problem is that the first part of that if statement doesn’t exist in
edge anymore so it fails. If you swap the if statement so that it
checks for :edge being set in the config first, then it never looks for
Rails::VERSION in edge rails and everything works fine.

I’ll see if I can’t whip up a patch for it.

I think I might’ve made a patch that resolves that last night - see
http://dev.rails-engines.org/repository/changesets/305 - however,
checking for :edge first might also been a good idea.

Can you add this line to the top of your environment.rb file (at some
point BEFORE the initializer):

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

The method for ‘activating’ edge engines behaviour changed a while
back, this should be reflected in the README.

Perhaps I missed it, but I was working on this pretty late last night.
In anycase, I submitted a ticket and patch for it.

Yes, indeed this works.
