Hello, folks!  
I’m playing with rails in my debian lenny system, and I’m facing some  
unsolvable difficulties now.

I’ve successfully installed rails, lighttpd and mysql from aptitude.  
Configuration took some time, but wasn’t the real pain.  
And finally I visit my ‘[http://localhost](http://localhost)’. Everything seemed to work  
properly. Introduction page was OK,  
‘[http://localhost/rails/info/properties](http://localhost/rails/info/properties)’ showed me correct info:  
\<--------  
Ruby version 1.8.6 (i486-linux)  
RubyGems version 1.0.1  
Rails version 2.0.2  
Active Record version 2.0.2  
Action Pack version 2.0.2  
Active Resource version 2.0.2  
Action Mailer version 2.0.2  
Active Support version 2.0.2  
Application root /var/www/local  
Environment development  
Database adapter mysql  
Database schema version 1  
--------\>

But when I tryed to add a simpliest controller, everything broke down.  
\<--------  
$ ./script/generate controller My\_Test  
exists app/controllers/  
exists app/helpers/  
create app/views/my\_test  
create test/functional/  
create app/controllers/my\_test\_controller.rb  
create test/functional/my\_test\_controller\_test.rb  
create app/helpers/my\_test\_helper.rb  
--------\>  
So everything should be OK. Test with rake is successful. But any ruby  
request gives:  
\<--------  
MissingSourceFile  
no such file to load – /var/www/local/app/helpers/my\_test\_helper.rb

Response

Headers:

{“cookie”=\>[],  
“Cache-Control”=\>“no-cache”}  
---------\>  
That is response to every request involving “public/dispatch.fcgi”,  
even the same ‘[http://localhost/rails/info/properties](http://localhost/rails/info/properties)’ attempt. The  
file ‘/var/www/local/app/helpers/my\_test\_helper.rb’ is actually in  
place and contains empty method MyTestHelper:  
\<-------  
module MyTestHelper  
end  
--------\>  
After deletion of controller, everything works again:  
\<--------  
$ ./script/destroy controller My\_Test

rm test/functional/my\_test\_controller\_test.rb  
rm app/controllers/my\_test\_controller.rb  
rmdir test/functional

How could I tame this error?  
Appreciate your help in advance, Kirill.

The same error is there.

no such file to load – /var/www/local/app/helpers/my\_test\_helper.rb  
And so on

has it done something silly like create the file with the wrong  
permissions, owner, something else ?

Oh, I’m really ashamed.

$chown -R kirushik:www-data /var/www/local  
and  
$chmod -R 775 /var/www/local  
solved the issue.

Thank you, Frederick.

And one more question - how can I configure script/generate to force  
it to set those permissions automatically each time?
