(new to rails) Error on flickr app

[Chris Gwynne]

Hi

I'm new to rails and am just trying out some tutorials before I delve
into it properly.

I'm trying to create the flickr app (found in the screencasts section on
rubyonrails.com)

I've built everything according to the video and all the code is correct
however I'm getting the following error.

NameError in FlickrController#search

uninitialized constant Flickr

RAILS_ROOT: ./script/../config/..

This error occured while loading the following files:
   flickr.rb

No idea what's causing it. Any help?

Can you post your flickr.rb model?

[Chris Gwynne]

Can you post your flickr.rb model?

It's here.. http://pastebin.com/701969

Installed by using gem install -r flickr

My flickr controller is

class FlickrController < ApplicationController
  def search
    flickr = Flickr.new '626ed109d2705948c31ca81e5e22051c'
    render :partial => "photo", :collection =>
      flickr.photos(:tags => params[:tags], :per_page => '24')
  end
end

Also my error out has changed, even though I haven't changed anything it's now..

d:/ruby/lib/ruby/gems/1.8/gems/flickr-1.0.0/flickr.rb:67:in `request'
d:/ruby/lib/ruby/gems/1.8/gems/flickr-1.0.0/flickr.rb:142:in `method_missing'
d:/ruby/lib/ruby/gems/1.8/gems/flickr-1.0.0/flickr.rb:102:in `photos'
#{RAILS_ROOT}/app/controllers/flickr_controller.rb:5:in `search'

I'm wondering if that screencast tutorial is outdated?

[Chris Gwynne]

Anybody?

[Fenrir2]

Is flickr.rb in app/models/ ?

Can you post the entire error page? It seems that you only posted the backtrace now, not the actual errormessage.

[xmitchx]

If I remember correctly, he downloads the Flickr Gem at the beginning of the tutorial. Did you do that? I'm not sure what its called but probably 'flickr' so:

  gem install flickr

hey chris,

are you actually still getting the NameError in FlickrController#search error, or is it something else now.

the error code you last posted was not complete, and looks like it was something else.

This error stems from the fact that the api key in the Flickr class constructor is invalid (it's a known bug -- see here for more: http://wonko.com/article/452). Browse to flickr.rb and edit the initialize method by replacing the api key that is there with your own. If it fails restart your server and try again.
