Hi,

i’m gald to hear, that Engines make steps  
towards Rails 2.0, so i’m able to port my redMine  
plugins now ;o)

in my first test, i found these 2 bugs:

1. 

the ‘rake test:plugins:all PLUGIN=xxx’ task abort with an Error  
(full path shorted and replaced with \<…\>)

\*\* Invoke test:plugins:units (first\_time)  
\*\* Invoke test:plugins:setup\_plugin\_fixtures (first\_time)  
\*\* Invoke environment (first\_time)  
\*\* Execute environment  
\*\* Execute test:plugins:setup\_plugin\_fixtures  
rake aborted!  
undefined method `mirror_files_from' for Engines:Module <...>/vendor/plugins/engines/lib/engines/testing.rb:74:in`setup\_plugin\_fixtures’  
\<…\>/vendor/plugins/engines/lib/engines/testing.rb:71:in `each' <...>/vendor/plugins/engines/lib/engines/testing.rb:71:in`setup\_plugin\_fixtures’  
\<…\>/vendor/plugins/engines/tasks/engines.rake:143

1. 

if i reload a view from a plugin-based controller, i get the following  
error every time:

A copy of ApplicationController has been removed from the module tree  
but is still active!  
/usr/lib/ruby/gems/1.8/gems/activesupport-2.0.1/lib/active\_support/dependencies.rb:237:in  
`load_missing_constant' /usr/lib/ruby/gems/1.8/gems/activesupport-2.0.1/lib/active_support/dependencies.rb:469:in`const\_missing’  
app/controllers/application.rb:31:in `user\_setup’

i don’t found a working ticket-system for rails-engines, so i think  
this list is the best way to report. please correct me, if i’m wrong.  
if you need some more info’s, please let me know.

thanks for your work  
Ralph

I’ve done this.

Hi Ralph,

I guess I’ve missed the fact that this method is used here (a test  
case is also missing). mirror\_files\_from is now a method on  
Engines::Assets, which of course doesn’t make a lot of sense. I guess  
it should be moved back to the Engines module or probably an  
Engines::Filetools module that communicates the purpose of this method?

Thanks for the report!
