Perhaps I''m an idiot and just don''t get it, and perhaps this question has been asked a million times before, but I''m not really sure how to go about searching for an answer to it: Why does my code Library.find(:all, :conditions => "user_id = #{session[:user].id}") return [] instead of nil when there are no results? -- Posted via

Hi All, I am new to this list and to rails. So far I am loving the way in which it is easy to put together web pages with a database backend. I would love to use the rails functionality (to do the sql queries) and then process the results using some very cpu intensuve tasks. The results will take far longer than it is viable to use a web browser to view the results. I would like to see the

Dear all Please see the following module, In module SX3 SX4 and SX5 have similar class Tasklist, but inherit from different class.

Hello, I need to access an mirrored database with one read and one write cluster. Is there a way to tell a model to use two connections? So that all updates etc go to the write database and all read from the read one? This is a fixed set up I can not use MySQL 5.x stuff and additionally i get a token on write, which can be checked on read (and wait for replication) if new data is needed. I

hello all, quick question: how can I find out if a given string matches the name of an ActiveRecord derived class? thanks in advance alan

Hi, Does anyone know much about abstract_class? Does it actually prevent instances of the class from being created? Does it disable certain methods? I already know what it''s for, but I want to know what setting self.abstract_class=true actually does. The reason I ask is that I want to use it for a slightly unorthodox purpose. I want a class who''s only attributes are its

First of all, sorry for the crossposting, but I put this into the Ruby Forum first of all, but was pointed to this as a more appropriate location. I''m using ActiveRecord and ActiveSupport in a non-rails environment to connect to multiple databases, and I''ve found the following (single database) to cause me an error. Note that params is my database settings and omitted for

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

Hi ... We are constructing at rails GUI using two differant databases, and this seems to work out nicely using a "establish_connection" per model, where each model enherit directly from ActiveRecord::Base. But ! I like to use a model where we can inherit from one parent class that handles the connection exactly as descripted in this document :

Hi all, I am facing with a new type of problem with railroad, explained below 1. I am using an oracle database in my application. In the database.yml file, I am having different schema connections to the same database.like development: database: real_database username: schema_name1 password: ************ adapter: oracle abcd_development: database: real_database

Hey all, I have two models in my rails project that share a lot of traits. They each have the same 4 properties, and now I need to add 2-3 methods to each one that will be the same. In the spirit of DRY I am looking for a solution to write these methods only once. Both of these models already inherit from ActiveRecord . . . and I didn''t know if it was safe to just "whip up" a

It looks like cached-model is broken again under rails 1.1. Can anyone confirm? Note that the exception below indicates it''s trying to treat CachedModel as the class name of the model, rather than using the proper class name (which is Entry in this case, and the table called entries). This is a model using Single Table Inheritance and acts_as_tree, and worked just fine under 1.0 and

Hello, I''ve got a problem with the inheritance as soon as I try to use it in a model. I''ve got plenty of items which can share a lot of code, so I created a class "Item", which inherits from ActiveRecord::Base, but because it''s not a "real item" but an interface, I set it abstract (writing abstract_class? method). Then I have all the differents

I am trying to create a null object in my application. I would like to assigned a null user object for anonymous/ mot-logged-in user, i.e. if session variable has nil data. In my User model, I have created a subclass like this: class UnassignedUser < User def save false end def update false end def username "Unassigned" end def county_id

Hi, I was trying to create an abstract class and a subclass which inherit that abstract class. However, seems like I cannot instantiate the subclass too. Below is my code: //abstractclass2.rb class Abstractclass2 < ActiveRecord::Base self.abstract_class = true end //subclass.rb class Subclass < Abstractclass2 end When I test drive it in rails console, I got the following error:

Hi, My application spans 2 (or more) databases for some very specific reasons... My models are working fine, even dynamically establishing connections as needed at runtime, and spanning relationships across the databases (which really impressed me). The problem is, I can''t seem to force Units for these models (that use a secondary db) to load their fixtures into and use the

Hello, I have an application that access two different DBMS - Firebird and Postgres. So far, that''s ok. The problem is, depending on the customer logged, a different database (Firebird) must be selected. To make the things clearer: Postgres: 1 database shared by all customers with these tables: - user - vehicle - driver Firebird: several databases with different names and identical
