Hello, I needed to add custom cache field for one of my application. I thought I will share the code showing how to do this. This code below creates and maintain a custom cache field, for keeping track of totals. Say, you have accounts, and for each account there are transactions (either deposit/withdrawal), and one will like to keep track of the total balance for an account. So, let there be a

Hi all. I am using LLVM to develop a procedural language. Can anybody point me to an example that uses CreateCall for a non-tail call? I am having trouble doing anything with the return value from the call besides returning it immediately. i.e. Passing the CallInst created by CreateCall to CreateRet is working fine, but I am having trouble storing the returned value in a local variable or

I will assume that my problem is either caused by my environment (VC7.1) or by the fact

Hi everyone, It''s been more than a month since I last fired up Ruby or ActiveRecord, so imagine my surprise when, after getting the latest source and running the unit tests for MySql, I was greeted with a screen full of errors. I''ll come back to the MySql errors later. What follows is the output I get when I run the tests for SQL server. I installed ruby with the one-click

Hi I am trying to create a plug-in to fix the error in the rails core produced by the multiple delete on a HABTM relationship. I have confirmed that my plug-in is being included into the base during runtime however the code does not seem to be overridding the base class. module ActiveRecord module Associations module ClassMethods def has_and_belongs_to_many(association_id, options =

I''ve discovered what I''m pretty confident is unexpected behavior in accepts_nested_attributes_for, and am developing a patch, but I''ve encountered a question about how the core team would prefer the implementation to look. Here''s the bug: when assigning to a belongs_to relationship (and I believe one-to-one, but I haven''t verified yet) if you mark the

Hi, While I was hacking ovirt-server, I have found that it's currently restricted to Postgres DB. Even if I like postgres for serious work on a server, I really prefer to hack/dev locally on a Sqlite or MySQL DB. I have googled on rails in order to find a good answer for the "foreign key problem" which forces OVirt to stay on pg. I have found a plugin on this particular

Hello, Rails provide counter cache field for associations, I want a similar cache for totaling up values (say account_balance = sum_of_deposits - sum_of_withdrawals). I was wondering if rails, already has another surprise in store for me, or is there any plug-in or how-to for doing these kind of things. Thanks. -- Surendra Singhi http://ssinghi.kreeti.com, http://www.kreeti.com Read the

This is my first rails app with a legacy database and I''m having a terrible time getting the models set up correctly. I have an order table that has a primary field named order_number. I have a name table with a primary of item_number. These two tables are liked by the item_number and the order_number, but not as you might think. If the order_number is 2500, then each entry in

Table articles has column: author,body,etc Table users has column: login_name,email,etc articles belongs_to user users has many articles foreign_key author references users(login_name) Therefore in Article.rb: belongs_to:article_user, :class_name=>"User", :foreign_key=>"author" and what''s going on? how the rails find the reference

I''m having a hard time figuring out how to build my application using Rails. As i go along, simple questions occur to me like: are you supposed to have a separate model class (each in its own file, in the app/models directory) for each table in your database? You''d think that something as basic as this would be laid out in the introductory documentation but, alas, the

When you define belongs_to in a model, you can either access association or association_id. I was wondering how Rails would handle things if you set each one to be different. I made two simple models: class Foo < ActiveRecord::Base; end class Bar < ActiveRecord::Base belongs_to :foo end Now here''s a script/console session. >> f = Foo.create => #<Foo:0x270ec10

Hi. I''ve tried to redefine the method belongs_to in ActiveRecord::Base, so every time a model is defined as belonging to :attachment, it should have some additional methods. I tried to do an alias of belongs_to, but this was not successful. The error message in Webrick was > Booting WEBrick... ./script/../config/../lib/ActiveRecordExtensions.rb:67: undefined method

Hello all, I am curious about what tools you guys use to make your databases. I know David uses CocoaMySQL. Are there other tools for other platforms and for other databases? I''m not very good with the SQL language, so I would like being able to do all my database setup with an easy-to-use tool (defining tables, fields, primary keys, foreign keys, indexes, etc.) Big kisses, Vincent.
