belongs_to causing NoMethodError exceptions ... ?
I''ve got a really strange problem using belongs_to. I apologize in
advance for the length... this is going to take a while to explain.
Basic idea: Creating a User requires that the user enter an email
address and activation key that matches an existing PendingUser.
After creating the user successfully, that pending user should be
marked as "used".
The problem:

Best way to implement?
So I''m new to all this Rails stuff and this is probably a database
design-related question to, but here it is...
Just for learning I''m trying to build a little real estate listings
application. Of course there is the listings model which will store
basic information like name, price, description, and all that jazz.
I''m to the point where I want to figure out how to

Newb question about facade columns
Hello,
I am trying to deal with a database table that contains a date in the
form of the number of seconds since epoch. Data is inserted in this
format by an existing script that I can''t change, so a schema change
isn''t realistic.
I would like to allow humans to view and edit this data in the form of
an actual human-readable date. I figured a facade column would be the

Nested resources and _path methods
Hi guys,
I was thinking aboiut this for a while:
If I have nested resource routes, for example /building/1/floor/2/
room/
3 (building has_many floors and so on), I have to call the room_path
method like this:
room_path @room.floor.building, @room.floor, @room
IsnĀ“t there a better way to handle nested routes with foreign keys, or
can I have this method overwritten somewhere?

Model setters, override attribute=(attribute)?
Hi,
I have a model similar Basket shown below. If customer_type is set
then it should also set customer to nil. Likewise, if I set customer,
it should inspect the customer_type attached to the customer and set
accordingly within Basket. However implementing it as below doesn''t
seem to work.
Am I missing a better way to achieve this? I had also considered using

Extending model
Hi,
I''m looking for a way to extend one of my models to allow some level
of abstraction between what goes into it and how it is stored.
For example, say I have a Product and I want to set it''s price. A
person using the website will type the price in euros. Internally, I''d
like to store the price as an integer value of cents.
I can currently do this with some ugly code

Suggestion: `before_save on: :create` should either work or raise an exception
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`,

set empty values as null in the database
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

Working around/with Restful Authentication
I''m using Restful Authentication, and the code to create a user is
pretty straight forward - there is a before_save action and a
before_create action:
before_save :encrypt_password
before_create :make_activation_code
But for some reason when I try to create a user programmatically in
the controller like this:

before_save :encrypt_password
I am having a problem finding the best way to make a "before_save
:encrypt_password" conditional.
I have to at times update user model attributes but each time I do this
the password is reencrypted because of the above. I need to
differentiate between when the user is first logging in and the password
does need to be encrypted, and when they are already logged in and the
