Hi everyone, Does Ruby support variable variables like PHP (http://www.php.net/manual/en/language.variables.variable.php)? Or do I have to use eval, like some_hash.each_pair{|key, pair| eval "#{key} = #{value}" } Or is there some other way? I''m actually trying to figure this out in order to use ez_where to create its conditions from a hash, so if this isn''t even

Hi All, I am trying to pass values to ez_where to construct my conditions. I need to know how the params need to be formated for ez_where. My search class looks like this: def search @display_ad = DisplayAd.new(params[:display_ad]) cond = Caboose::EZ::Condition.new do pub_date == ''@display_ad.pub_date'' io_number =~

Friends- I wanted to let people know that there is a new experimental release of this plugin. I would love feedback on syntax and features. There is now a full test suite with fixtures that covers all the available syntax. Look at the test suite for more syntax possibilities. There have been many additions since my last release. Fabien Atelier has been working on this with me and has

Hi everyone, I have 3 types of people (for now): Staff Faculty Students To break them up into classes, but keep them in the same People table, I''ve broken them up like so (code and ''ends'' snipped): class Person < ActiveRecord::Base class Employee < Person class Staff < Employee class Faculty < Employee class Student < Employee So, when I insert

I''m having fun composing queries with ez_where, but am stuck on how to formulate the following using the ez syntax: (begin_date >= ? OR end_date >= ?) AND (description LIKE ? OR name LIKE ?) There are two clauses, each containing OR operators (the ez ''any'' syntax) but both clauses must evaulate to true for a match. Can anyone suggest the proper way to construct

I am trying to allow for AND type ''find'' but to allow for simply a single set of find criteria. controller code... @vw_string = @vw_string1 = @vw_string2 = @vw_string3 = [] if params[:beg_intake_date] != "" then @vw_string1 = ["intake_date between ? and ?", params[:beg_intake_date], params[:end_intake_date] ] end if

Hi there, I''m puzzled by this apparently simple query I can''t manage to reassemble using ez_where plugin. cond = Caboose::EZ::Condition.new :my_table do start_on < Time.now any {end_on > Time.now; end_on.nil?} end I keep getting the following result : >> cond.to_sql => ["my_table.start_on < ? AND (my_table.end_on > ?)", Tue May 23

I have the following code: condition_clause = "%#{@phrase}%" logger.info "condition is #{condition_clause}" unless @phrase.nil? condition = Caboose::EZ::Condition.new :affiliates do affiliate_name =~ "%#{@phrase}%" # <<< here''s the problem end options[:conditions] = condition.to_sql logger.info "ajax

I''ve been trying to use the ez_where plugin to create a dynamic finder. The structure looks somehing like this.. === controller === def list attribute_filter = params[:filter] @filter = Caboose::EZ::Condition.new :table do attribute <=> attribute_filter if attribute_filter end # ... do the find with the @filter # end === view === .... <%= link_to

I just keep thinking this is going to slice through queries like a hot knife through butter, but... there''s something I''m not getting. Here''s the gist: # get the people like the search criteria Members.find(:all, :conditions => [''first LIKE ? OR last LIKE ?'', params[:search], params[:search]) joined with the alternative of

I''ve been playing around with some easier ways of specifying conditions in active record, and have come up with a little plugin that some may find useful. Currently active record finder and calculations methods can take a :conditions option with a string or array listing some sql conditions, eg: Animals.find :first, :conditions => "name = ''Tiger''" My

I noticed there are a lot of PHP based dynamic text replacement examples out there such as: http://artypapers.com/csshelppile/pcdtr/ Is there anything like this for Ruby / Rails? I know there''s always SiFR but that method is often frustrating because I''ve noticed significant slow down in page load time even on pages that use it sparingly.

Hi! It''s rather ruby question than rails... I have a single ''list'' action where i call paginate method. I can receive none, 1 or 2 variables that specify conditions for paginate method. How to write the code so i can call paginate without conditions if all conditions variable are nil, with a single condition if one of conditions variables is not empty and with 2 if

Hi people, I''m looking into polymorphic associations as a way to cleanup some messy parts of my code. I think they will allow me to do exectly what I need, but since there''s little to none written on this subject, I''d be delighted if someone could shed some light on this. Especially what the different options and needed table structures need to be. Thanks, -

Hello friends- There is a new release of the ez-where plugin. This plugin makes it easy to do complex ActiveRecord queries without writing any SQL. Ruby operators are mapped to SQL operators like so: foo == ''bar'' #=> ["foo = ?", ''bar''] foo =~ ''%bar'' #=> ["foo LIKE ?", ''%bar'']

Hi all, I''ve been playing around with Arel this week (actually outside of Rails) and found an issue with the clone implementation. I''ve added a patch and a testcase here: https://github.com/codders/arel/commit/660f706491ac012cb133554cffeaa6b9ae6046e9 and made a pull request against the rails/arel repo. I''ve also been playing around with support for ordering on

I''ve been googling around trying to find some tips on creating tests for plugins. Am I correct in assuming that I''d have to have the tests as part of a rails app in order to test the plugin? I''d like to find a way to do standalone tests for the plugin. -- Posted via http://www.ruby-forum.com/.

I am ''raking'' my brain to fix this problem - I have searched, googled, looked through rake documentation, wiki.rubyonrails and I can''t fix... This works $ rake plugindoc (in /home/craig/ruby-db/th-db) rdoc -o doc/plugins/ez_where --title ''Ez Where Plugin Documentation'' -- line-numbers --inline-source -T html

Hi guys, Is there an elegant way to capture the sql that would have been executed by an ActiveRecord statement, without actually executing it? :) I''m imagining something like sql = User.find(1).groups.to_sql or perhaps sql = ActiveRecord::Base.capture_sql { User.find(1).groups } resulting in sql = ''SELECT * FROM groups INNER JOIN memberships.... WHERE users.id =

Ok, I searched but couldn''t find anything and I even tried the RoR IRC channel with no help. I get this error: uninitialized constant Airport I used this code which I got from the RoR site. helper :sorting def list @sorter = SortingHelper::Sorter.new self, %w(icao host_id name), @params[''sort''], @params[''order''], ''icao'',
