could anyone by chance give me a working example of the .uniq! method? i''ve been trying all day. any help would be much appreciated! jon -- Posted via http://www.ruby-forum.com/.

Is there an R analog of the Unix command uniq -c: http://en.wikipedia.org/wiki/Uniq Given an array x, uniq -c replaces each contiguous subsequence of identical numbers with a tuple (count, number). E.g. $ cat > usample 10 10 9 8 8 7 7 7 6 3 1 1 1 0 $ uniq -c usample 2 10 1 9 2 8 3 7 1 6 1 3...

Hello *Gem* experts, Sorry for asking multiple questions in one post but they are both related to one problem. So far I have the following code: class Member < ActiveRecord::Base has_and_belongs_to_many :blogs, :uniq=>true ..... end class Blog < ActiveRecord::Base has_and_belongs_to_many :members, :uniq=>true ... end The issue is that :uniq=> true isn''t working and multiple records are being inserted in blogs_members table when I call the following in Member clas...

Didn''t have quite enough space to describe it there...basically i''m having a problem with the :uniq option in my tags. I''m using acts_as_taggable_on_steroid which adds these associations to my Resource class: Resource has_many :taggings, :as => :taggable, :dependent => :destroy, :include => :tag has_many :tags, :through => :taggings, :uniq => true This uses the join...

Hello, I am trying to pass a conditional expression into an expression to be evaluated when ever an R statement is called. For example: get_unique_count <- function(df, select, field){ uniqs <- unique(subset(df, select)[field]) return (nrow(uniqs)) } In this case select is a conditional statement year == 1980, and the function would be called in the following manner: library(ggplot2) get_unique_count(mpg, year==1980, 'man...

Getting the through items from a has_many :through :uniq relationship In a nutshell, I have been using the has_many :through :uniq relationship, and I want a DRY way to list the join model objects.

...) role_ids = [] specific.each do |role_item| role_ids << role_item.role_id end all_actions.each do |role_item| role_ids << role_item.role_id end all_controllers.each do |role_item| role_ids << role_item.role_id end role_ids.flatten.uniq end which of course is not DRY at all. I could not find how to merge class instances (specific, all_actions and all_controllers) or how to make only one find to use the selection statements above (at least not in a easy to read way) It would be better if I could do something like: def self.au...

Hi I wonder what the state of this ticket is: http://dev.rubyonrails.org/ticket/2019 Does anyone have information regarding whether there are plans to fix this behaviour? It seems strange to me to force uniqueness in Ruby (i.e. application code) but not in the database. For example, in activerecord/lib/active_record/associations/ has_and_belongs_to_many_association.rb there is a line which reads @reflection.options[:uniq] ? uniq(records) : records This would be superflous if the "<<...

I''m returning some rows from a tags database that look like this: ID WORDS 1. apple banana pear 2. banana melon 3. apple peach lime What I want to do with that data is use the .split method to divide them into separate values in an array, then use the .uniq method to return a unique list of the words like so: apple, banana, pear, melon, peach, lime So in my controller I have: def taglist @tags = Tag.chop_em(params[:tag]) end and in my model I know I need something: def self.chopem(tag) Tag.find(:all) end I think I lack the understanding of ho...
