Support for foreign keys in Migrations
Is there any work being done to add support for defining foreign keys in
ActiveRecord Migrations? If not is it something that people would find
useful or do most people here believe in the "Application Database" style
over the "Integration Database" style [1] as defined by Fowler?
I''d love to see support for foreign keys in Migrations. For selfish reasons

aligning Ferret''s IndexSearcher.search API with Lucene''s
Recently I''ve been revisiting some of my search code. With a greater
understanding of how Java Lucene implements its search methods, I
realized that one level of abstraction is not present in the Ferret
classes/methods. Here are the relevant method signatures:
Ferret''s search methods:

Not wishing to instigate a DB war, but...
Can I get some opinions on which free DB to use with rails for a virtual
server that will eventually be doing lots of heavy database lifting?
Not a lot of heavy duty querying per se. Think multiple simultaneous
forums and blog sites and the like.
I know each of the different DB possibilities such as MySQL and
PostgreSQL has plus points and minus points. I''m particularly
interested

Program logic behind Ruby On Rails
Hi, I''m a newbie in both Ruby and Ruby on Rails. I finished the Ruby on
Rail Tutorial on Todo list and it was great. But, now I''m trying to
understand the logic behind it, that is something that is not obvious on
how each one of them ties together.
Is there a flowchart that shows how the inner working of Ruby on Rails?
In another words, let''s suppose we consider the

find_all_by deprecated?
Is find_all_by deprecated and/or find_first_by for 2.0.2? If not,
what is actually deprecated? just find_all(..) and find_first()?
Thanks for clearing this up.

FK constraints overrated?
Hello folks,
I use to think that a relational databases without foreign keys
constraints enforced strictly by the RDBMS were no good, piece of crap,
data junk.
However, I''ve also learned the hard way that FKs constraints imposes
serious difficulties when moving data around, specially between
different DBs, or for loading test data or for upgrading DBs schemas, or
for porting DBs

Serialized object behaves weird
Hi!
I got a class named EinsatzFilter which I serialized to session. Before
saving to session it works afterwards I keep getting the message:
"undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from
ActiveRecord::Base inherited class.
Code:
class EinsatzFilter

Bind Variables in Active Record
OK, I have some basic functionality to support bind variables, it
appears to work with the ''old'' %s style too.
I''ve altered sanitize_conditions in
activerecord/lib/active_record/base.rb to check whether bind variables
are in the statement (/\?/). If they are, replace all the ?s to
escaped values from the arguments array. else santize and expand.
There are a few

Mocking, changing method interfaces and integration tests
Suppose we have a method ''foo'' which internally uses another method
''bar''.
Being good BDDers we mock out the ''bar'' method. After all, we only
want to spec the ''foo'' method - actually running the ''bar'' method
means slower, less maintainable and brittler specs. That''s why we <3

[OT] Best Blog + Wiki opinions?
Hello all,
I''m looking for suggestions for integrated Blog + Wiki (Bliki) apps. I''d
prefer Rails, I want to hear opinions on all options!
I''ve browsed through W:Bliki <http://en.wikipedia.org/wiki/Bliki>. Nothing
in that list is immediately compelling.
This is for my wife, who is not a technologist, and has a need to create a
information-centric website.

Building a conditions clause (for find) of multiple optional params?
I want to be able to find items according to various params - category_id, member_id, type_id,
rating, etc. What I have now is something like:
if(@params[''category_id''])
@items=Item.find(:all, :conditions=>["category_id=?", @params[''category_id''])

Should counter_cache fields be saved in the database?
As far as I can tell, the counter_cache option on a belongs_to model
doesn''t actually save anything in the database. For example, I have
the following models:
class Parent < ActiveRecord::Base
has_many :children,
:conditions => "deleted_at IS NULL"
end
class Child < ActiveRecord::Base
belongs_to :parent, :counter_cache => true
end

validate uniqueness of two fields
I have Proposals and Members and Members can vote for a proposal only once.
So, I have "Vote belongs_to :member, :proposal", but to make sure a member only votes
once, I want to make sure that there isn''t a vote in the db with that member_id and
proposal_id. I can just put the appropriate find in a vote.valid? but I wanted to make

find_all order question
How does one properly get find_all to grab the data from the DB table
ordered by a specific column?
For example:
@anglers = Angler.find_all
This code gets all the angler records and they are sorted in order of
the id field which is of course set as a primary key in the DB (mysql).
I''d really like to pull the data from the DB sorted in the order of
another field, for example

AJAX form inside table - error
Hello,
I need to put an AJAX, form such that it is inside a table, and spans across
few rows.
But, what I am noticing is that, while submitting the form, the data in the
fields is not submitted.
If I move the form outside the table or inside a cell, things work OK, but not
when the form is inside the table and spans few rows. This problem is only
with AJAX forms, regular forms work perfect. I

Overide the default find_all
Hi,
In my model i want to overide the default find all for sorting purposes.
Is this possible or can this only be done in the control or by adding a
custom method in the model.
def self.find_all()
@contents = Content.find(:all,
:order => ''pos, position_id'')
