Hi. I have a model in Rails 3. When creating the record, there are a total of 3 columns for the model. Right now, Rails allows for creating a record if only 2 of the 3 records are populated? In rails, how do you tell Rails only create a record if 3 values for each column exist when creating? thank you ...

I am trying to write specs for a working file upload functionality using attachment_fu. However, the sample code given by the author for testing requires me to require action_controller/test_process so that I have access to ActionController::UploadedStringIO class. I have used this before in rails 2.x but for rails 3, it fails to locate ...

A couple of my model classes are getting a little cluttered with all these "validates" calls, so I thought I'd be able to move them into a separate class and 'require' that, but it doesn't seem to work. class Auction < ActiveRecord::Base require 'auction/validations' ... class Auction::Validations include ActiveModel::Validations...

Hi, I'm using Ryan's solution to add and remove nested model fields dynamically through JavaScript using jQuery. There are 4 models: client, c_person; project, p_person. And one-to-many associations: client has many c_people and project has many p_people (these are people from client side but they belongs to project). Hope it isn't to...

What's the equivalent of relative_url_root in ActionMailer? I've tried setting it up in default_url_options, but it appends the parameter in the query string. Adding :skip_relative_url_root = false doesn't work either. Using :host = 'somehost.com/subdir' does work, but is that appropriate? Thanks! ...
I have a complex form (like Ryan B's Complex Form Railscasts) where I have a few levels of database tables being altered at the same time.

How can...
