I’m a bit of a n00b, so my problem is more that I can’t figure out the  
last step from other posts.

I want to launch some controller methods in application.rb from a  
script, so I’m trying to use the console to help write it.

?\> require “app/controllers/application.rb”  
=\> true

> > ApplicationController.post\_render(:id =\> 119)  
> > NoMethodError: undefined method `post\_render’ for  
> > ApplicationController:Class  
> > from (irb):5

> > ApplicationController.instance\_methods  
> > =\> [“methods”, “web\_service\_object”,  
> > “render\_nothing”…“post\_render”,  
> > … “gem”, “transition”, “silence\_stream”]

What really silly thing am I doing wrong?

It looks like you might be using irb rather than the console. irb is  
just  
Ruby. script/console loads your development (i.e., Rails) environment.

I’m using whatever loads when, from the ruby root directory I run  
`script/console`

I’m using:  
#!/usr/bin/env ruby  
RAILS\_ENV = ‘development’  
require File.dirname( **FILE** ) + ‘/…/config/environment’

as the header to the final script (which appears to give me a very  
similar environment to the console)

The ‘require’ line does appear to be redundant though.

My methods are in instance\_methods, but not in methods, if that helps.

you don’t have to require it in script/console.

If you want to test your action in script/console, call it  
as if it were a browser :

app.get ‘my\_url’

(like app.get ‘article/show/2’ )

and inspect it :

app.response.body  
app.controller.params  
…

Is there another way to do it? I’m using .htaccess files to tie  
authentication to our LDAP servers and I just get 401s
