Undefined method `has_attached_file'' with paperclip 2.3.8 gem for Rails 2 using Ruby 1.8.7
Hello,
I am trying to use the paperclip plugin in my rails app to upload images
for posts. I am using Rails 2.0.2 and ruby 1.8.7 on Ubuntu 10.04 os for
project specific purposes.
I am referring to the following tutorials for this :-
1. http://railscasts.com/episodes/134-paperclip?view=comments
2.
http://jimneath.org/2008/04/17/paperclip-attaching-files-in-rails.html
I did a git clone on the paperclip plugin via:-
https://github.com/thoughtbot/paperclip , but the command like `ruby
script/generate paperclip group_post photo` didn''t generate a migration
for it. I then created a migration for the same through ruby
script/generate and uploaded the appropriate columns of my table
`group_posts`.
I then tried to install the gem and since I am using activerecord and
activesupport 2.0.2 I used paperclip 2.3.8 gem from rubygems.org.The
undefined method error still persisted, I really couldn''t figure out
why.
Now here.. the command `ruby script/generate paperclip group_post
photo` worked perfectly fine for me.
The current error I am getting exactly looks like this:-
undefined method `has_attached_file'' for #<Class:0xb67119f0>
The **Application Trace** for the same is:-
/home/mohnish/.rvm/gems/ruby-1.8.7-p334/gems/activerecord-2.0.2/lib/active_record/base.rb:1532:in

My groups_controller.rb show method looks like this, here line 27 is
`@group_post = GroupPost.new(params[:group_post])` :-
def show
@investor_group = InvestorGroup.find(params[:id])
@members = @investor_group.activated_members
# code taken from discuss method
investor_id = session[''investor_id'']
@investor = Investor.find(investor_id)
@members = @investor_group.activated_members
unless
@current_user.is_an_existing_member_of_group(@investor_group)
flash[:notice] = "Please join this group to participate in
discussions"
redirect_to :action => :show, :id => @investor_group and
return
else
@group_post = GroupPost.new(params[:group_post]) # line 27,
tried GroupPost.create also.. seems to be of no avail..
end
#@group_post = GroupPost.new(params[:group_post])
@group_post.investor_group_id = @investor_group.id
@group_post.post_by = investor_id
unless @group_post.message.blank?
if @group_post.save
flash[:notice] = ''Post was successfull''
else
flash[:notice] = ''Post was not successfull''
end
#redirect_to :action => :show, :id => @investor_group and
return to change.. appropriately....
end
#if @group_post.message.blank?
# flash[:notice] = ''Post can\''t be blank.''
#end
@group_all_posts = GroupPost.find(:all, :conditions => [
''investor_group_id = ?'', "#{@investor_group.id}" ],
:order =>
''created_at DESC'')
# code taken from discuss method
end
The group_post model looks like this with line 9 having the following
code has_attached_file :photo :-
class GroupPost < ActiveRecord::Base
has_many :group_comments
belongs_to :investor_group
validates_presence_of :message
#include Paperclip
require "paperclip"
# Paperclip
has_attached_file :photo # line 9
end
Part of my view file where I am trying to upload the picture along with
a post looks like this:-
<%form_for :group_post, @group_post, :url => {:action =>
:show},:html => {:multipart => ''true''},:id =>
''new_post'' do |f| -%>
<p><label>Start
Discussion:</label><br><%=f.text_field
:message%></p>
<%=f.file_field :photo%></p>
<p><%=submit_tag "Post"%></p>
<%end%>
I tried what was given in:-
-
http://stackoverflow.com/questions/2661062/installing-paperclip-undefined-method-has-attached-file-for-ruby-on-rails/3373493#3373493
This option didn''t seem applicable to my case as it seems to be using a
higher Rails version
-
http://stackoverflow.com/questions/3886088/undefined-method-has-attached-file-after-paperclip-installation
I tried restarting my server, but it didn''t solve my problem;
- https://github.com/thoughtbot/paperclip/issues/192
I tried the include Paperclip - but it really didn''t seem to help my
case...
I have added a require in my group_post.rb and in my environment.rb file
as require "paperclip". I still get an undefined method error. I
don''t
know why..

http://stackoverflow.com/questions/2743902/nomethoderror-undefined-method-has-attached-file
On referring to this I tried Imumar''s fork of paperclip, I manually
pasted it in my vendor/plugins directory after git cloning it.. I got
the following error( I have a feeling there surely would have been a
dependency issue as his version might be compatible only with a higher
rails version:
mohnish@mohnish-desktop:~/UP/dev$ ruby script/server -p 4000
