similar to: Is eval the only way?

I have several tables for enumerations. They all have the same content: id, name, position. I''d like to avoid the tedious work of defining a class for each one explicitly. Not least, in order to avoid clutter in the model directory. Here''s what I''ve come up with: class EnumRecord < ActiveRecord::Base def self.define_enums(*enums) enums.each do |spec|

Hi All, Is there a way to do join queries with find() or is it best to use find_by_sql() instead? I''m looking to do something like: SELECT winery_name, wine_name FROM winery, wine WHERE wine.winery_id = winery.winery_id AND winery.winery_name LIKE ''Borg%''; Thanks! : ) Jason

I''m trying to dynamically create an instance of an object at runtime, from a String. I have a method that returns one of a number of Strings ("Car", "Motorcycle", "Bicycle"), and when I receive the String, I then want to instantiate one of those objects. Seems like there should be a way to do it in Ruby, but maybe I''ve been up too long --

Using the paginator helper, is there a way to determine what page an item in the collection is on? Thanks in advance for your help!

Which do you guys prefer for credit card processing? Both look like they get the job done. -- Is there any consensus on which one is better? Are there other credit card processing solutions I''m not aware of? Any thoughts or suggestions would be most welcome. Thanks! : ) Jason -- Posted via http://www.ruby-forum.com/.

I have the following 3 models (2 models joined by an intermediate): 1. class Exercise < ActiveRecord::Base 2. has_many :routines, :class_name=>''RoutineExercise'' 3. end 1. class Routine < ActiveRecord::Base 2. has_many :exercises, 3. :class_name=>''RoutineExercise'', 4. :order=>''position'' 5. end 1. class

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

The subject line says it all. -- Is there a way to do something like: page.replace_html "#{var_containing_id_name}", :partial => ''edit'' That line of code does not work, but I would like to pass the name of a variable to page.replace_html. This variable would contain the id of the div I want to update. Anyone know if/how I could do that? Thanks! : ) Jason

Hello, I am trying to use the multi_search method, but I keep getting type error on nil objects, I send it [Model1,Model2] and it seems as though the class names keep getting clobbered and turn to nil, somewhere along the multi_index area. I tried to trace what was going on, but I got nothing, also, this only happens when there are actually hits(thank god, most of the time). Perhaps some insight?

is there a way to stub a method that sets an instance variable, so the stub sets it too? def find_foo @foo = Foo.find(params[:id] end ... controller.stub!(:find_foo).and_assigns(:foo, "123") -------------- next part -------------- An HTML attachment was scrubbed...

Here''s a simplistic model class. class Person < ActiveRecord::Base has_and_belongs_to_many :relatives, :class_name => ''Person'', :join_table => ''relatives'', :foreign_key => ''from_id'', :association_foreign_key => ''to_id'' has_and_belongs_to_many :brothers, :class_name =>

>> reload! Reloading... => true >> puts Class < Module true => nil >> puts Module < Class false => nil >> puts Module < Object true => nil >> puts Object < Module false => nil >> Object.parent => Object The above indicates that the Class object instance inherits from the Module object instance and the Module object instance

Every once in a while, I pipe up and whine that "belongs_to" should really be ''refers_to" [http://dev.rubyonrails.org/ticket/2130]. It''s time again. I''ve got a bunch of stuff going onto eBay, so, like any good engineer, I don''t just post it manually: I design a Rails-based inventory database that creates a semantically-correct XHTML/CSS auction

So, I sat down to use set_fixture_class, and it bombed on the first thing I tried: set_fixture_class :content_drafts => "Article::Draft" I made a quick patch, and I''d appreciate a quick run through your tests to make sure it doesn''t disturb anything: http://dev.rubyonrails.org/ticket/4095 As I was typing this, I realized that the string gives us no benefits.
