similar to: ordering after a inject

Looks like I have skipped on this, but still - a couple of questions: 1) Why there suddenly is an OrderedHash in ActiveSupport? (this glaring omission from ruby core is present in many apps already) 2) Why it doesn''t match the semantics of Hash respectively? 3) Why it''s #nodoc ? -- Julian ''Julik'' Tarkhanov please send all personal mail to me at julik.nl

I have Rails 1.1.2 installed and froze my app to 1.0 by checking it out into the vender directory. Maybe it''s coincidence, but now when trying to do rake migrate I get this: > rake migrate --trace (in /home/beet/workspace/) rake aborted! superclass mismatch for class OrderedOptions /usr/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/ordered_options.rb:27

The code on http://blog.craz8.com/articles/2005/10/28/acts_as_taggable-is-a-cool-piece-of-code is based on the acts_as_taggable gem,anybody has done that using the acts_as_taggable plugin?thanks! btw:the code above uses the tag_count method,which is defined in the gem: def tags_count(options = {}) options = {:order => ''count DESC''}.merge(options)

Dear Rails groups, thank you for all the previous helps in this group, and me being a newbie is getting more comfortable with rails and now I finish most of the scaffold modification without much problem. My question is(I know it''s absolutely basic questions but I''m a real outsider :~( ) I have been developing in my own pc, now my office ''s other people will test on it,

Hi, I'm trying to get better at things like lapply but it still stumps me. I have a function I've written, tested and debugged using individual calls to the function, ala: ResultList5 = DoAvgCalcs(IndexData, Lookback=5, SampleSize=TestSamples , Iterations=TestIterations ) ResultList8 = DoAvgCalcs(IndexData, Lookback=8, SampleSize=TestSamples , Iterations=TestIterations ) ResultList13

hello everyone, Any idea how can i export a resultset from a database to a CSV or XLS file from the application ? would like the user to have the option to export selected data to a CSV/XLS file. Any plugins or libraries avaiable to accomplish this ? Thanks for your time, VASU. -- Posted via http://www.ruby-forum.com/.

Simple question: I know how to access a data field in a hash by doing hash_name[datafield_name]. But what if the datafield itself is a hash? I tried a couple of variations but nothing seems to be working and tutorials do not go into such details. Is there a simple way or should I create separate instances? -Chris -- Posted via http://www.ruby-forum.com/.

Hi, My mails were working with the earlier version of rails ie. Rails 2.0.2. But recently when i upgraded my environment to 2.3.2 the mails stopped working and gave "Error: End of file reached". But if i send mails independent of my rails app the mailing code works fine. My Environment: Windows Xp Ruby 1.8.7 actionmailer (2.3.2) actionpack (2.3.2) activerecord (2.3.2) activeresource

I noticed that ActiveSupport::OrderedHash disappeared from the Rails API pages. Does it mean that it is going to be deprecated? I know that Hash is ordered in Ruby 1.9, but this subject seems controversial, and in my opinion the ordered hash in Ruby 1.9 should have been called OrderedHash (or SequentialHash), even if it be an alias of the current implementation of Hash. That way one would be free

Originally posted on github, reported to the right place. I would like to open a discussion about how `to_json` and `as_json` operates in Rails from a performance standpoint. I''m using Rails 3.2 but this issue applies to almost all versions of Rails. Our use case presents the challenge in sending out potentially large JSON (or XML, but we''ll focus on JSON rendering here)

Hello, I''m currently trying to understand some problems I had in the past with mixing look-back with blktap(2) for HV and PV domains. I''m stuck reading the source code, so I''d like to get some help from the list. Interrupt me if I got something fundamentally wrong in my understanding so far: 1. With pure-HV the domU gets an emulated IDE (or whatever) disk. The

Quick question to see how I might re-sort an Activerecord data set. Let''s say I have this table: tablename: testscores | id | student | score | avg_for_year 1, steve, 85, 82 2, tom, 84, 92, 3, jim, 92, 95 In my controller, I have something like: t= Testscores.find(:all, :order => "score DESC", :limit => 2) ...where it would return the records for Jim and Steve.... My

This is probably simple, but I just can't see it... I want to calculate the R^2s for a series of linear models where each term is dropped in turn. I can get the RSS from drop1(), and the r.squared from summary() for a given model, but don't know how to use the result of drop1() to get the r.squared for each model with one term dropped. Working example: library(vcd) # for

Hi,I am using the amazing package 'plyr". I have one problem. I would appreciate help to fix the following error: Thanks. ______________________________ > library(plyr) > data(baseball) > summarise(baseball, + duration = max(year) - min(year), + nteams = length(unique(team))) Error: could not find function "summarise" > ddply(baseball, "id", summarise, +

I understand that ActiveSupport::OrderedHash.new [[1,2]] does not work beginning with Rails 2.3. I am running Rails 2.3.2. One commentator suggested simply creating the instance without arguments and then sequentially adding each element as a separate step. I tried that. The hash gets populated just fine but it is not ordered. Can anyone please tell me what the magic trick is under

Hi, I''ve a model with the following method: def self.run(sql) return connection.select_all(sql) end so, the value returned is an array of hashes... the problen is that the sql command: "select name, id from table" and select id,name from table" returns the columns in the same order (name, id). And in my view, I need to keep the order of the SQL command.

Hi everybody, I''ve started to learn Ruby on Rails with the two books, of course I''m experimenting outside the examples in the book and walking against some things I didn''t learn yet. so here''s the question: Is it possible to access one model from within another? Actually I have a Many to Many relationship between tables and I''m trying to realize

I can't seem to figure out why I'm getting this error. The output is copied right off the screen. Notice how in some cases the back slash is missing. In other cases, it can't read a file that I know is there. Thanks in advance > library(foreign) > hrout <- read.spss("c:\\hrab200.sav") Error in read.spss("c:\\hrab200.sav") : unable to open file
