search for: extract_options_from_arg

[Sorry for the poor subject; this is really hard to explain] I''m trying to run a search over several objects which themselves contain multiple model objects, like so: class Collection << ActiveRecord::Base def findpkg self.repositories.each do |r| p = r.packages.find(:all, :conditions => "name like ''%pkg%''") end end end

Hi, i was wondering if there was a nice clean way(after all, it is ruby) to change the find method of a certain model/class (Page) so that if i wanted to use a find method on a @page instance it would return only specific rows from the table(if the page.published == true/false: the pages table looked like SQL: ... id int not null auto_increment, published tinyint(1) not null, something

...: class Day < Foo def self.find_all_with_appointments (*args) find :all, { :select => ''distinct foos.*'', :joins => ''INNER JOIN appointments ON days.appointment_id = foos.id'' }.merge (extract_options_from_args!(args)) end has_many :results , :class_name => "Result", :foreign_key => "event_id" end :include doesn''t help here, as it produces an outer join.

Hi, I want to share some helpful code snippet. Can it further be optimized? Or is this even good to do? Put this in your model to write a customized find method having more conditions: def self.find_active(*args) options = extract_options_from_args!(args) conditions = "AND (#{sanitize_sql(options[:conditions])})" if options[:conditions] options[:conditions] = "ADDITIONAL_CONDITIONS_GO_HERE #{conditions}" args << options find(*args) end regards, Helmut

How would I overload find? I got some excellent help on mixins for my classes using lib/, but it doesn''t allow find to be overloaded. I''m testing with the example method below: module myModule def find(*args) options = extract_options_from_args!(args) validate_find_options(options) set_readonly_option!(options) case args.first when :first then find_initial(options) when :all then find_every(options) else find_from_ids(args, options) end find_init...

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

...love the acts_as_* family that rails uses. I''ve also found I can create something similar by dropping the following code into my activerecord classes: class MyClass < ActiveRecord::Base class << self alias_method :count_with_unapproved, :count end def self.find(*args) options = extract_options_from_args!(args) if options[:conditions].nil? options[:conditions] = ["status = ''approved''"] end args << options super(*args) end def self.count(conditions = nil, joins = nil) logger.info conditions.inspect if conditions.nil? conditions = "status = ''approved&...
