Hello fellow Ruby enthusiasts!
Although I''ve been using Ruby for some time, I just started using
RoR. I''m experiencing an error that I''m having trouble
resolving and
was hoping to find some help.
I am getting this error message when I try to hit a certain URL:
http://localhost:3000/captionfiles
NoMethodError in CaptionfilesController#index
undefined method `all'' for Captionfile:Class
app/controllers/captionfiles_controller.rb:5:in `index''
Here are my files:
class CaptionfilesController < ApplicationController
def index
@captionfiles = Captionfile.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: @captionfiles }
end
end
.............
class Captionfile < ActiveRecord::Base
validates :title, :presence => true, :length => { :minimum => 2 }
validates :filename, :presence => true
has_many :run
end
............
Cccweb::Application.routes.draw do
resources :captionfiles
resources :runs
get "pages/choose"
get "home/index"
get "runs/new"
root :to => ''home#index''
end
.................
I''ve searched the internets as well as many message bases, and
although I come up with variants of this message, none of the
solutions seem to help.
Thank you!

Creating records for example. I assume you have you tried restarting the server. Are you sure you have not got Captionfile declared in another file somewhere? Perhaps you kept a copy of captionfiles.rb with an out of date definition in it. Do a global source search for Captionfile in your project. That should be has_many :runs by the way (plural) but I don''t think that is anything to do with this problem.

So can you just confirm which version of Rails you have installed. Older (very old!) versions didn''t have ".all", you had to use ".find(:all)".

Does it work when you run Captionfile.all in your rails console?

Hi Michael -- I am using Ruby v1.9.2p290, Rails v3.2.2, and rvm 1.8.5. I checked to see if I had duplicate files, but to no avail. I will do some deep digging this morning. If I find a solution, I''ll post it. Thanks for your help.

Hi Colin, I did try restarting the server, etc. I still can''t fix the problem. I am going to do some deep-diving into the code today. I suspect it has something to do with a file like routes.db, or similar. The code seems to be ok -- there''s something else that isn''t quite evident that''s causing this issue. Thanks for your help!

Hi Colin, Thanks for the reply. Your question prompted me to search around my class declarations, and sure enough, I found the problem. I declared two container classes, Captionfile and Run, to capture information in a convenient, encapsulated format. From there I create objects to make arrays/hashes for processing I stored them in the /lib directory, which apparently conflicted with the ActiveRecord class declarations of the same name. I renamed the class files and suddenly it all worked. I now have to figure out how to include these class files without conflict (I''ll likely rename them). Thanks for your tipoff! That''s what lead me to my solution.
