[karthik chigurupati]

Greg,

I am experiencing this same error "undefined method `slice!' for
#<Hash:0x46137b8>". I am new to ruports.I Used ruby 1.8.6 and rails
1.2.6
its my first report i am not able to work my way out. I even
updated to rails 2.1.2 and experienced the same problem.



controller method
-------------------------------
def show_report
table = Site.report_table(:all,
:only => %w[site_number site_name site_region
site_on_air_date site_address site_phone_number],
:conditions => ["site_number = ?" , params[:site_number]],
:group => "site_number")

grouping = Grouping(table, :by => "site_number")


sorted_table = grouping.sort_rows_by("site_number", :order
=> :descending)

send_data sorted_table.to_pdf,
:type => "application/pdf",
:disposition => "inline",
:filename => "sites_report.pdf"
end
--------------------------------------------------------------------

view code:
---------------------------------------------------------------------
<%= link_to ("reports", :action => 'show_report', :site_number =>
@site.site_number) -%>
----------------------------------------------------------------------

Unfortunately AAR has not been fixed and I have not found time to
investigate. This may be fixed in the Odaeus fork of Prawn, but I'm
not sure.

I believe Hash#slice! is a Rails 2.x method included in ActiveSupport so
it should have worked when you upgraded. My hunch is you may have
upgraded the gem but not the version lock in config/environment.rb.

Anyway, you will find that the version Gregory provided a link to
includes a patch from Marcus Derencius that allows Rails 1.x compatibility.

The easiest way to install is to just download the latest from GitHub
and extract to vendor/gems/acts_as_reportable and you may need to do
something similar to this article to load it:
http://blog.jayfields.com/2006/10/rails-autoloading-gems-in-vendor.html

Best regards,
Andrew

Hello Andrew,
I have already run gem install acts_as_reportable should
i do any uninstallation before i extract
Odaeus / acts_as_reportable into my vendor folder? I cannot find Gem
folder in my vendor should i directly extract to my vendor folder?

and add-

Dir[File.dirname(__FILE__) + "/../vendor/*"].each do |path|
gem_name = File.basename(path.gsub(/-\d+.\d+.\d+$/, ''))
gem_path = path + "/lib/" + gem_name + ".rb"
require gem_path if File.exists? gem_path
end

to my envronment.rb

is it all i should do to remove slice! error?

You shouldn't need to uninstall the original gem as the code in vendor
should take precedence.

You're right that the code on the page I provided expects it in
vendor/name_of_gem but I also noticed it checks for version numbering as
well which is a bit annoying.

I should have read that page more clearly before providing the link, I
instead suggest the one I use:
http://errtheblog.com/posts/50-vendor-everything

And is much simpler:
config.load_paths += Dir["#{RAILS_ROOT}/vendor/gems/**"].map do |dir|
File.directory?(lib = "#{dir}/lib") ? lib : dir
end

Just create vendor/gems/ and extract AAR into its own subdirectory. It
will then be added to Rails' load paths to be loaded automatically when
required.

Yes, or you can just upgrade Rails to the 2.x series.

Hope that helps,
Andrew

Andrew,

Thank you so much for your long patience reply. But still i am
not able to require the odeous AAR gem into my application.

MY Environment.rb
------------------------------------------------------------------------
RAILS_GEM_VERSION = '1.2.6' unless defined? RAILS_GEM_VERSION

# Bootstrap the Rails environment, frameworks, and default
configuration
require File.join(File.dirname(__FILE__), 'boot')



Rails::Initializer.run do |config|

config.load_paths += Dir["#{RAILS_ROOT}/vendor/gems/**"].map do |
dir|
File.directory?(lib = "#{dir}/lib") ? lib : dir
end

require "ruport"

end
--------------------------------------------------------------------------
if i dont add require "ruport/acts_as_reportable" i am getting
undefined local variable acts_as_reportable
if i define Odaeus/acts_as_reportable it throws n error to

Karthik

I'm sorry but I don't understand what you're saying. I've listed the
steps below but this is just a reiteration of the previous advice.

1. Click on 'download' at
http://github.com/Odaeus/acts_as_reportable/tree/master.
2. Extract the archive into vendor/gems/acts_as_reportable.
3. Add the loading script to environment.rb as you've done or if you're
having trouble with that just:
require
"#{RAILS_ROOT}/vendor/gems/acts_as_reportable/ruport/acts_as_reportable"
(on one line)

I'm afraid I cannot probably help any further. I would strongly advise
upgrading to the latest version of Rails if possible.

Regards,
Andrew
