Uninitialized constant Files::Magick -still around

Hi there,
I’m solving the problem about the plugin Magick. In my app in Gemfile
I’ve follwoing:

require ‘rubygems’
require ‘mongo’
require ‘RMagick’

include Magick

and in a model Files:

class Files
def self.save(upload)

img = Magick::Image.read(‘public/data/nature6.jpg’).first
end
end

And I still getting error in subject of this post. I tried to move
require ‘mongo’
require ‘RMagick’

into the method self.save, but without succes…

But if I try to test, that the plugin is installed fine (test.rb):

require ‘rubygems’
require ‘RMagick’

puts Magick::Long_version

I will get following output:

This is RMagick 2.13.1 ($Date: 2009/12/20 02:33:33 $) Copyright © 2009
by Timothy P. Hunter
Built with ImageMagick 6.6.7-8 2011-03-16 Q8 http://www.imagemagick.org
Built for ruby 1.8.7
Web page: http://rmagick.rubyforge.org
Email: [email protected]

So I guess this plugin is installed right… And I have a problem, that
I don’t know why this plugin doesn’t works in RoR application…

Thanks a lot for every hint advance! :slight_smile:

That looks like an odd to thing to have in your Gemfile. Your gemfile
should contain stuff like

gem ‘mongo’
gem ‘RMagick’

etc. not actual require statements

Is your app actually using the gemfile at all? If you’re using rails
2.3 there some messing around you need to do in order to get bundler
to work (it’s all on the bundler home page)

Weird. I think you need to get bundler working properly in your app
first. Does bundle show think rmagick is part of your bundle ?

run bundle show from the root of your app

Fred

You can “freeze” all of the gems into your site, so you don’t have to
rely on your host’s version of anything. Have a look on the bundler
site for the incantation. These frozen Gems get partially compiled (at
least that’s how it appears to me) so there may even be some advantage
to running them this way.

If I started with RoR, I was excited from it… but the problems with
plugins I really don’t like… And the problems really comes again, when
I will to try to upload my app on hosting and there will not installed
all of plugins in my app…

I think you need to read up on how bundle works, and where it writes
information.

Edit your gemfile to your heart’s delight. If you don’t run “bundle
install”, then those changes aren’t seen/processed.

Why weren’t you successful with editing your gemfile? (your second post
in this thread)

It seems a relatively simple thing, and if you edited that file, and did
a “bundle install”, and that process reported issues, then you should
resolve those.

Add it to your Gemfile (as Fred’s post earlier) and run
bundle install
(did you remember to run bundle install previously?)

Colin

Thank you for your replies guys. I made “bundle install” in my root of
app… but if I see then on plugins, I didn’t see RMagick… The output
from “bundle show” is the same, as I posted here (9th post)…

Where can be the error? What could be wrong yet…

One more time, thanks

Look back at Fred’s first post (as I suggested) where he explained
that is not the correct syntax for Gemfile. I suggest you do some
research on how to use bundler.

I suppose you could try ::Magick although that wouldn’t make much
sense unless something was confusing the constant lookup stuff
