Hi,

I’ve been having problems getting some things to run in rails that run  
fine standalone. There’s this cool ruby reporting framework called  
ruport, which I have running from within rails, but when I try and add  
support for more complex things (like graphs) that require their  
extension ruport-  
util things fail in rails with no error reported, but still work fine  
from within irb. I have the appropriate gems installed:

ruport (1.4.0)  
A generalized Ruby report generation and templating engine.

ruport-util (0.13.0)  
A set of tools and helper libs for Ruby Reports

and as I said I can manipulate graphs from the irb prompt:

irb(main):001:0\> require ‘rubygems’  
=\> true  
irb(main):002:0\> require ‘ruport’  
=\> true  
irb(main):004:0\> require ‘ruport/util’  
=\> true  
irb(main):006:0\> g = Graph(table.column(‘date’))  
=\> #\<Ruport::Data::Graph:0x14a54b0  
@record\_class=“Ruport::Data::GraphData”, @column\_names=[“01 December  
2007”,

however when I try to so the same within a rails application  
(currently fired from script/runner), I get failures with no errors  
when I try to include “require ''ruport/util” in my rails code.

I have required ruport fine, but inclusion of the a  
ruport/util require leaves script/runner giving me this output:

samuel-josephs-computer:~/Code/myproject samueljoseph$ ruby script/  
runner Statistics.ruport \> test.pdf

Run ‘script/runner -h’ for help.

there are no errors in the development log, and if I remove the  
ruport/  
util require statement I get an error about use of the graph object:

samuel-josephs-computer:~/Code/myproject samueljoseph$ ruby script/  
runner Statistics.ruport \> test.pdf  
/usr/local/lib/ruby/gems/1.8/gems/rails-1.2.6/lib/commands/runner.rb:  
47: undefined method `Graph’ for #DailyStatsRenderer:0x4bd53e0  
(NoMethodError)

suggesting to me that rails is having trouble requiring ruport/util,  
because this error indicates that everything else is working except  
for access to ruport/utils

is there something special I have to do to access error information  
from rails when importing third party libraries?

I’ve tried putting the require of ruport-util in all sorts of other  
places in the code, but no joy.

Any help will be greatly appreciated.

Many thanks in advance

Well suggestion number one is to use the debugger to start poking  
around. Suggestion 2 is to write Ruport::Data::Graph instead of Graph.
