OSX Leopard - undefined method `has_attached_file'

[discoposse]

Ok...I've hit the wall on this.

OS X 10.5.7
Ruby 1.8.6
rails 2.3.2
paperclip 2.1.2
thoughtbot-paperclip 2.2.9.1

Followed the coding process here: http://railscasts.com/episodes/134-paperclip
but I'm using the gem rather than the plugin

Generates this:

NoMethodError in ItemsController#index

undefined method `has_attached_file' for #<Class:0x17e59e0>

I've also added require 'paperclip' to my environment.rb and confirmed
by running script/console that require 'paperclip' returns []

Any ideas?

You have two versions of paperclip installed? What's your `rake gems` look like? Does it show paperclip as installed or frozen?

Also, if you could paste some code here in the list or throw it on Gist, that would probably help more. http://gist.github.com

[discoposse]

Sorry about that. That probably confused things. I did have 2 gems
installed.

I've removed the paperclip 2.1.2 and still get the same results.

I've put up the code from the files. It's dead simple: git://gist.github.com/128194.git

My setup was:

1. Install thoughtbot-paperclip gem (sudo gem install)
2. Install ImageMagick (confirmed to be working)
3. Generate scaffold description:string price:string
4. Generate paperclip migration
5. Run migrations

Confirmed the table contains my fields and the photo_ fields

can you instantiate a new Item object from script/console?

[discoposse]

Same error

>> @item = Item.new
NoMethodError: undefined method 'has_attached_file' for #<Class:
0x18c9424>

I know that this is probably something dead simple...but somehow it's
eluding me

[Marlon Moyer]

ok, try this: http://gist.github.com/128269

you should be able to do this without an error. If you are getting an
error, something is probably wrong with your paperclip install. Are
you running the default ruby on osx?

[discoposse]

:(

Same result. NoMethodError: undefined method 'has_attached_file' for
#<Class:0x183196c>

I have upgraded the ruby environment (I heard that the one shipped is
a problem). I'll try to remove the gem and re-install to see if I get
any better results.

let me know if there are any other suggestions.

[Marlon Moyer]

which environment are you using? REE?

[Marlon Moyer]

is this the only gem you're having trouble with. Are you using any
other gems?

Do the 'gem' and 'ruby' command both point to the same environment?

All other gems are working ok. Environment is traditional RoR (no
REE). Mongrel etc...

[Marlon Moyer]

you said you rebuilt the environment, what do the following commands show:

which gem

which ruby

which irb

Did you remember to write:

requires 'paperclip' (or requires ' Paperclip' or whatever)

in the envireonment.rb???

[discoposse]

I've fixed the issue by using the plugin rather than the gem. Not
really a fix, I would much rather use the gem. If I get a chance to
get past this I'll post the solution. Thanks for all your help :)

[Jonathan Yurek]

What does your environment.rb look like? Can I see the config.gem line
you had that was specifying paperclip? It should be able to work
perfectly fine from a gem (although I'm glad it works as a plugin for
you), so I have to think there may be a config issue somewhere.

When I add require 'paperclip' to my environment.rb it doesn't work,
but when I add it as config.gem or as a plugin it work's fine. Any
specific reason. I have tried all possible tries.If I add it in the
model then also it work fine.:(


irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'paperclip'
=> true
irb(main):003:0>

Thanks,

Kilari,

My guess is that you added require 'paperclip' to the top of your environment.rb instead of the bottom.  Paperclip automatically adds methods to ActiveRecord::Base if the ActiveRecord constant is defined.  ActiveRecord isn't loaded until after the initialization that is done in environment.rb.

More importantly, why are you trying to avoid config.gem or plugin?

Ryan,

I have tried all the possible combination's but with fail to use it as
a gem.There is no particular reason to use it as a gem but was just
trying to make it work on the production server as it works fine on
the dev machine as a gem.

Thanks,
Kilari.
