Error on running any controller- Noob question


#1

Hi ,

I am running on Vista with webrick …
When I generate controllers , models and views I get an error as
under.

C:/Ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/active_support/
dependencies.rb:105:in const_missing' C:/ROR_lpapp042109/app/controllers/afflnetworks_controller.rb:5:inindex’

I tried reinstalling but kept stumbling on this.

gem -v
1.3.2
rails -v
2.3.2
ruby -v
ruby 1.8.6 (2008-08-11 patchlevel 287) {i385-mswin32]

The full stack trace is as under if that helps

Have you tried looking at afflnetworks_controller.rb around line 5, the
error message suggests there is a problem there. It is difficult to
help
without more information.

Thanks for your reply Colin

Yes, I did.

Line 5 reads is @afflnetworks = Afflnetworks…

The default scaffold commmand generated line 5 as under. In both cases
I get the same above error

def index
@afflnetworks = Afflnetworks.all

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

end

I changed it to as follows.

def index
@afflnetworks = Afflnetworks.find(:all)

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

end

The same thing also happens when I call any method in the controllers
and all the controllers. Think it is more than just that one line of
code.
