Hi, I was thinking of doing this with a stored procedure, but I thought it could be better implemented in Rails. I have several tables that hold a counter cache for other tables, which aren''t directly related. For example: Table ''schools'' has records that belong_to table ''counties'', and that table has records that belong_to table

Just for the record, I want to let the list know that I succeeded in booting a modified Universal TCP/IP Network Bootdisk floppy from http://members.iinet.net.au/~bdriver/bootdisk/ I started with a Win98 Bootfloppy from http://www.tobs.uku.co.uk. Then I made a disk image from this, using dd.exe from cygwin. Then I converted this disk image from 1.44MB to 2.88MB with winimage. Then I copied

I have the following tables setup: locations :id :name systemmessages :id :name systemmessage_validtimes :id :name :systemmessage_id :location_id :start :end The systemmessage_validtimes has a ''has_many'' relationship with systemmessages, meaning that there could be many valid times for each system message. @systemMessage = Systemmessage.find(1) E.g.

I''ve got a publications table that contains an author_id foreign key and a pubrole_id foreign key. What I want to do is query the DB using AR so that I can get a list of all publications that belong_to a particular author, and group the results by the pubrole.role_name (Author, Joint Author, Editor, etc.) so that the results look something like: Author book1 info book2 info etc.

def update @product = Product.find(params[:id]) @product.attributes = params[:product] if params[:main_image] image = Image.new params[:main_image] if image.save @product.main_image.destroy if @product.main_image @product.main_image = image else @product.errors.add_to_base(image.errors.full_messages.join(", ")) end end

Hey all, I''m rather new to Ruby and Rails (and not great with SQL), but I''m developing a ride sharing app and would like to be able to sort on something I don''t have stored. I have users, events, and rides, each of which has a zip code. Events have_many rides, and rides belong_to events. When an event is selected, I''d like to be able to show a list of

Hi all, I''m running Rails on top of a Mongrel cluster. I have several model classes that are going to have so many records it is not feasible to keep them all in the same table. So I''ve split out the records into many different tables, each with its own suffix which corresponds to the id of the model to which all records in that particular table belong. For example,

I''m working on a simple CMS. The main data type are "listings" a listing habtm (has_and_belongs_to_many) categories and subcategories. Subcategories belong_to categories. Subcategories are basically the same as categories, but they are treated differently in a few situations. The problem is, I can''t seem to write the view/controller/model code that allows me to

I am very new to Rails. After skimming through the documentation over the last several days, I''m struggling with the appropriate use of belongs_to. My main question is whether a model can have several belongs_to declarations. I have not seen any examples online show that usage. If it can, then I would like to know if it''s poor form or what the best practices are around

I am implemented a simple project management application. Each project has various events, and each event can be a different type. Some event information is common, such as name, start date, close date, and comments. I have a projects table which has_many events. My plan is to have several sub-event tables, like event_get_access which will contain an event_id field to link it to table events as

In AWDWR David says (pg 232), "When a Join Wants to Be a Model: While a many-to-many relation with attributes can often seem like the obvious choice, it?s often a mirage for a missing domain model. When it is, it can be advantageous to convert this relationship into a real model and decorate it with a richer set of behavior. This lets you accompany the data with methods. As an example,

I''ve been struggling with a strange nested transaction problem for a while. I have a two objects with the following relationships: Mail has_many :recipients Recipients belong_to :mail I''d like to update the status of the Mail object while sending mails for each of it''s recipients. Following is a simplified example that I''m having problems with: def

I''ve started to put together a custom expectation matcher for specifying AR associations. Its not quite complete and I really need to put some specs together for it, but I''d appreciate any comments. It lets you spec your associations like this: describe Record do include ActiveRecordAssociationMatchers it "should belong to artist and use a counter cache" do
