Hey guys,

I’m trying to access a YAML file to set up some options in a select  
drop-down that was previously hard-coded.

I have the following in my controller:

require “yaml”  
require “pp”  
require “util”  
require “date”

# set the path

$LOAD\_PATH \<\< File.join(File.dirname( **FILE** ), ‘…/’)

require ‘rate’  
require ‘test/unit’  
require ‘yaml’

#require ‘rubygems’  
#require ‘ruby-debug/debugger’

YAML\_CONFIG\_FILE\_STR = “LawyersProfessionalLiability.yaml”  
YAML\_CONFIG\_FILE =  
File.join(File.expand\_path(File.dirname( **FILE** )),"…",YAML\_CONFIG\_FILE\_STR)

class LplShortFormAppsController \< ApplicationController

def initialize(filename = “LawyersProfessionalLiability.yaml”)  
# load all lookup tables  
@RateLookup = YAML::load(File.open(filename))

```
reset

```

end

def new  
# load all lookup tables  
@RateLookup = YAML::load(File.open(YAML\_CONFIG\_FILE))  
@deductibles = @RateLookup[“Deductible”]  
@desired\_limits = @RateLookup[“Liability Limits”]

```
@lpl_short_form_app = LPLShortFormApp.new

respond_to do |format|
  format.html # new.html.erb
  format.xml { render :xml => @lpl_short_form_app }
end

```

end  
…  
end

And the code in the view doesn’t matter yet because I keep receiving:

Errno::ENOENT in Lpl short form appsController#index

No such file or directory - LawyersProfessionalLiability.yaml

RAILS\_ROOT: /Users/brwn/work/demo  
Application Trace | Framework Trace | Full Trace

/Users/brwn/work/demo/app/controllers/lpl\_short\_form\_apps\_controller.rb:31:in  
`initialize' /Users/brwn/work/demo/app/controllers/lpl_short_form_apps_controller.rb:31:in`open’

I don’t know why. Where is the YAML file supposed to go? I’ve tried  
placing it in /app, /public, /views/, /views/lpl\_short\_form\_apps (the  
view where the YAML file is being called to load).

Can anyone assist?

Thanks,  
Ahad

Rather than guessing where it is, have you tried printing out the  
value of YAML\_CONFIG\_FILE ?

Actually, I tried and failed. I used puts YAML\_CONFIG\_FILE in the index  
action as well as in the initialize method, but the server output showed  
no information upon reaching the error. I thought to put it into the  
Request section by using params[“debug”] = YAML\_CONFIG\_FILE but that  
also had no effect, except to make an empty Request section show up. I  
thought, well, maybe the path isn’t being setup at all, except the error  
specifically states the LawyersProfessionalLiability.yaml file, without  
any path, so I know it’s getting set, I just don’t know to where or how  
to make it display where.

Well, I tried puts on a lot of different areas and I was able to expose  
the problem. It came down to a simple parameter value not being passed  
in properly.

Thanks for the assistance.
