Le''s say that I have a table called people and the column middle_name is nullable. If the user enters say blank or empty space then in the database it is recorded as empty space. I would like in all my models all empty spaces to be recorded as null. I guess I can write a plugin which will do so for all the models but I''m sure something like that should already be existing.I

I need to call callback only if the validation was successful, but it seems it is called also when validation fails. -- Posted via http://www.ruby-forum.com/.

I''m trying to order a find through a has_many association. I have a model called SalesOrder. Each sales order has things like amount, description, etc. I use the following to get the Sales Orders: @sales_orders = SalesOrder.find(:all) And I display them with: <td><%= link_to sales_order.id.to_s, :action => ''show'', :id => sales_order.id

In the language I am working on, there are cases where the call flow graph can affect the type of a variable. A simple example is a "nullable" type (a pointer which is allowed to be NULL), which can be converted into a non-nullable type via an if-test. So for example if x is nullable, and I test x != NULL, then inside the conditional block the type of x is no longer nullable.

I have a question about regarding the use of ''has_one'' in this scenario: Schema: User ---- id first_name last_name UserMessage ---- user_id message_id Message ---- id Assuming business rules dictate that a Message can have at most ONE User (let''s assume a message can be created without a user associated to it), these are my questions: 1) How would I use has_one

Hi, after some experience with Rails on MySQL databases I gave it a try on one of our larger Oracle database. I was facing a problem when Rails tried to detect the columns for a model/table. The appropriate statement ran about 1 min which led to a timeout. Our Oracle guru told me to analyze the SYSTEM schema. After that hadn''t helped, he said the only remaining chance is to use a

I''m just looking into how to connect to Oracle using Rails. I''ve got everything connecting and working as it should.

There''s a small inconsistency in ActiveRecord''s callback syntax that has tripped me up before. It wouldn''t be a big deal, but it can lead to a silent failure. I''d like to suggest that it either be made consistent or be made to fail loudly. The issue is that to do something before validating, but only when creating, you use `before_validation on: :create`,

I wanted to fix some things up in the trunk, so I set up the databases and ran the unit tests. A bunch fail for postgres, and even more error out. I know of two postgresql adapters: postgres-pr and ruby-postgres. Strangely, they each fail different tests. So if I want to fix things up, which one should I be using? For that matter, which adapter should I be using for production? Finding out
