Hello everyone, I''m having trouble figuring out which approach is better. I have the following tables: products, orders and line_items. Every time an Order is placed, the quantity field in the products table has to be updated for each LineItem in the Order. One option is to use DB triggers which is not as portable as using before_create in the Order model. But with before_create I cannot

I have not used the... script/generate

howdy! I had the problem that attachment_fu didn''t make a thumbnail, but everything else worked. I read this post http://www.ruby-forum.com/topic/104213 and added a parent_id column. now I get the following error when I trie to add a photo: undefined method `find_or_initialize_by_thumbnail_and_parent_id'' for Photo:Class my code is: class Photo < ActiveRecord::Base

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.

One problem I sort of always had with the ActiveRecord''s tight coupling to the SQL backend is how slow it makes the unit tests. OK, there are some ways to make it faster at a price of extra complexity (reusing the fixtures, doing a rollback in the end of the test, etc), but still - it is much slower than what I would like a unit test to be. Today I had a very simple idea (why, oh why

I have a problem getting attachments to work in a specific case... I have the following data model (this is a relevant subset of it): - a log can have many journals - a journal belongs to a log and can have many attachments - an attachment belongs to a journal When adding on a new journal to an existing log the new journal form and the corresponding controller handle the attachment as well and

I''m working with a legacy postgresql database where the names of tables, columns, etc., do not usually follow Rails conventions. I''ve been able to work around it for the most part, but I ran into this: I have the following test: require File.dirname(__FILE__) + ''/../test_helper'' class SponsorTest < Test::Unit::TestCase self.use_transactional_fixtures =

I want to be able to change the redirection url after I called redirect_to, is that possible? My specific use case is that I want to change the default redirection of "Login Engine" method signup, but I am seeing no other way then copy/past and change the parameters of redirect_to.

Hi Railers, I am trying to create a simple application like a guest book which has users and uses sessions to keep track of which users are logged on. The user''s page is constructed after doing some SQL queries and the user clicks on another link and hits the back button I dont want to regenerate the whole page (which is what happens now) .So I want to use some kind of caching mechanism.

I''m working on a plugin which needs to add both schema and data to the app database, and I''m trying to figure out the best way to do it. I''d like to use a db migration to modify the schema and load the data from a YAML fixture, but Rails doesn''t seem to support migrations for plugins. To do so, the schema_info table would need to change to include a

Hiya - before I start let me tell you i''m a Nuby on Rails. I''ve created a user registration within my application that requires email validation and that seems to be working fine. I''m now creating the user login page and have the following code in my UsersController: def login @user = User.new @user.username = params[:username] end def

I tried creating variables using names of the form fields, but

I get an "undefined method ''tag''" when I try to use the acts_as_taggable. Note that it''s not the issue of bouncing webrick after changing the environment.rb file. (I stumbled on that too... :-( ).

I found the post about needing to install acts_as_attachement_1_1_6 if you are not on edge rails. But I am having trouble getting db_system storage to work.
