Application doesn't work on two different machines

cojones · July 2, 2009, 3:31pm

Hello,

I’ve got an application which I am developing on a Windows machine and
everything works just fine. Once I upload it on my server (Debian) and
test it I get following error:
ActionView::TemplateError (undefined local variable or method `filename’
for #News:0x41105540) on line #8 of news/index.html.erb:
5:
6:

7:
8: <%= image_tag(news.public_filename)
%>

9: Erstellt am <%=
news.created_at.strftime("%d.%m.%Y") %>

10: von <%=h news.author %>
11:

I’m using attachment_fu.

Anyone knows why it doesn’t work on my debian machine?

Thanks

Start by making sure you are running the exact same versions of both
ruby and rails. Make sure all of your gems and gem versions are the
same. Make sure you are including rubygems (require ‘rubygems’) before
requiring your gems in environment.rb to make sure there are no
conflicts.

I personally go through my production server and run an irb require test
on every gem I use on development…

irb

require ‘rubygems’
require ‘name of gem’
require ‘name of next gem’
=> all should come as ‘true’

After you’ve done that, read the following regarding the image paths you
are having trouble with:

http://www.ruby-forum.com/topic/164189

Your issue and his are similar.

cojones · July 2, 2009, 4:50pm

It looks like you are using a plugin such as attachment_fu. Ensure
that you have that included in your deployment to production.

Yeah, it’s gotta be something to do with attachment_fu cause I’m calling
a attachment_fu function.
I just realized that my Windows machine has rmagick (2.9.0) installed
and Debian rmagick (1.15.0). That could be the reason right?

Just gotta figure out how to update rmagick then…
checking for wand/MagickWand.h… no
Can’t install RMagick 2.10.0. Can’t find MagickWand.h.

Wrong forum I know but anybody knows what the heck is going on there?

attachment_fu is inside the plugins folder so should be alright=

Perhaps try upgrading imagemagick first before installing rmagick.
i updated imagemagick by compiling and installing it manually but now i
get this error message

Putting aside the RMagick issue (can’t really help you there), do you
have the full error trace for:

Which version of rails are you developing with locally?

On Fri, Jul 3, 2009 at 11:54 AM, Heinz

cojones · July 3, 2009, 6:09pm

I think in your production environment you are using an older version
of Rails (review your error trace):

/usr/local/lib/ruby/gems/1.8/gems/activerecord-2.1.0/

You should vendor your rails with your application to avoid this in the
future.

Looks like it’s an incompatibility with the version of attachment_fu
and active-record/rails.

Cheers,
Nicholas

cojones · July 3, 2009, 6:49pm

I meant attachment_fu

cojones · July 3, 2009, 6:55pm

I just updated attachment_fu and did a db:migrate:reset and now
everything works like a charm Thank you!

cojones · July 3, 2009, 6:59pm

OK, could have been a version conflict between Rails and
attachment-fu. One thing I didn’t think of asking was to ensure you
had run the migrations in production. Pleased to hear you are good to
go.

Cheers,
Nicholas

Have you tried updating attribute_fu? Where did you source it from?
