When I run:  
script/generate scaffold\_resource Tranche

I get the following error:  
Showing app/views/tranches/index.rhtml where line #24 raised:  
undefined local variable or method `new\_tranches\_path’ for #\<#\<Class:  
0xb6985718\>:0xb69856f0\>

I have a number of other resources that seem to work fine when  
generated the same way–it’s just Tranche that’s creating problems. Is  
this some kind of reserved word? Or is there a pluralization issue?

Any help would be appreciated!

Hey,

First of all, when you use new\_xxx\_path() you should use the singular-  
form of xxx, which _should_ be tranche in this case.

However, in the console it’s pretty easy to see that there is a  
problem with the singularization of ‘tranches’:

“tranche”.pluralize.singularize #=\> “tranch”

Which means that map.resources :tranches will force you to use  
new\_tranch\_path etc.

You can fix this in your map.resources call:

map.resources :tranches, :singular =\> ‘tranche’

Then you can do: new\_tranche\_path, edit\_tranche\_path, tranches\_path.
