Question

Sorry if it is a dumb question, but the issue is quite straight forward. If I do,

$ rails new testproj
$ cd testporj
$ rails plugin install git://github.com/technoweenie/attachment_fu.git

Which should just create a empty proj and install attachment_fu in it. But then, trying to start it up:

$ rails s
=> Booting WEBrick
=> Rails 3.2.2 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
DEPRECATION WARNING: You have Rails 2.3-style plugins in vendor/plugins! Support for these plugins will be removed

The heck? What did I miss?
It is rails 3.2.2 on windows I have installed.

thanks,

plugin install will be deprecated in rails 4.

Gems are now preferred, which are added to Gemfile in your application’s root directory and installed with bundle install

attachment_fu is not very well supported with rails 3, I’d use carrierwave instead. You can use Rmagick’s to_blob method to store the images in the database.
