I have the following code in app/controllers/processjobs\_controller.rb

# 

class ProcessJobsController \<ApplicationController  
def index  
@ProcessJobs = ProcessJobs.find(:all)  
end  
end

# 

This is my route file …  
ActionController::Routing::Routes.draw do |map|  
map.resources :ProcessJobs

map.connect ‘:controller/:action/:id’  
map.connect ‘:controller/:action/:id.:format’  
end

When I point my browser to localhost:3000/ProcessJobs, this is what I  
see in the log file. When I see the first few lines, it appears that  
rails is trying to logon as ‘sa’. The database.yml file has the  
following contents.

development:  
adapter : sqlserver  
mode : odbc  
dsn : Driver={SQL Server};Server=  
database : ODS  
username : \<definitely\_not\_sa\>  
password :

The log file also shows this :  
NameError (uninitialized constant ProcessJobsController)

Not sure how to interpret this message.

The contents of the log file follows:

Either change your filename to  
“app/controllers/process\_jobs\_controller.rb” or make the “J” on job  
lowercase.

Just do  
./script/generate scaffold ProcessJob  
from project root directory and watch what the names of model,  
controller etc and compare
