Prevent duplicate HABTM associations
Hi,
I am trying to restrict duplicate has_and_belongs_to_many associations.
I tried to find support for a association validation for duplicates but
couldn''t find anything.
I understand I could use :uniq=>true on the model association but this
would only prevent it from displaying duplicates, I want to stop
duplicate associations being inserted in the first place.
I have a vague

Not Active Record Model Validation
I have a problem with ruby on rails validation
total_book_toy.rhtml
================
<%= text_field ''book1'', ''title1'' %>
<%= text_field ''book2'', ''title2'' %>
I want to validate these text_field so user can''t insert same title.
However, I was stuck how to do it.
Or maybe you have another way how to do it.

Newbie validation question

The validate routine is attempting to see if another record with the

This is the validation code:
def validate
if Product.find(:all, :conditions => ["artist_name = ?, title = ?,

How do I test a unique index?
I have a loans table and a payments table. Each loan has_many payments.
So far no problem.
Now, the payments table has a payment_number field, and each payment has
a payment_number unique within that loan. For example, Loan A can have
payment_numbers 0, 1, and 2 and Loan B can have payment_numbers 0, 1, 2,
and 3 (but only one of each payment_number). I can enforce this with a
unique index in

Creating a safe sequence generator
Hi all,
I''ve got a rails and database question. Accounts have jobs, and job
numbers should be assigned per account. Account 89 should have jobs
1-whatever, which are not the same as account 67, which has jobs
1-whatever.
In the past, I have accomplished this quite easily with:
create table job (
accountid int(10) unsigned not null default 0,
jobid int(10) unsigned not null

Rails validation is inefficient
Hi,
I have a User model, with a validates_uniqueness_of :login
The generated SQL for the validation is:
SELECT * FROM `users` WHERE (LOWER(users.login) = ''fernando'' AND
users.id <> 10001) LIMIT 1;
and it takes 0.13s to happen (my table has 10.000 rows)
When I use the EXPLAIN instruction on it, it shows that it will use the
