long waiting time for first page due to session[:user]
hi everyone
i am developing http://sprinj.com
it uses a login system, quite simple, really, similar to loginEngine
the problem is that takes way too much time to access the first page. when i
desactive the login system, there is very noticeable difference (about 2 to
3 seconds), and people who visited the website complained about this.
is there something i can do to speed the sessions checkups ?

STI and :through, not working?
Artist.first.medias returns all medias. Media is an STI. Media can be
video or painting.
How do I return all paintings of an artist? Only paintings, not
videos?
In my Artist model, I tried putting:
has_many :paintings, :through => :medias
In console, I do:
Artist.first.paintings.all
And I get:

Change to has_many :through associations
Hi everyone. I''ve made a default change to has_many :through
associations that I felt was important to make before they''re
released. This is after some tickets and confusion I''ve seen
regarding has_many :through.
class Connection < ActiveRecord::Base
belongs_to :user
belongs_to :channel

Building a Search Page as part of CRUD
I''ve been experimenting with Rails over the past couple of days and
have come across something that seems harder than it should be. In
previous frameworks I have used (WebObjects, php) a full search page
(which leads into a list view populated with search results) was part
of the CRUD that was either dynamically or statically created after
specifying table/object schema. In

many-to-many relationships with itself. In this case, it''s person who
can become friends. The join table looks like this:

problem with merge
I have used merge regularly and thought I understood how it worked, but
I must not. I have two dataframes with identical colnames from two
different experiments, TL01 and LC01. Each dataframe has a column named
"Entrez.Gene", which I have converted to "as.character" just to make
sure merge is not looking at factor levels. Because I have done some
filtering, the Entrez.Gene

I''m sure apps like these can be built, but can they scale to

How to query with calculations?
Hi,
I would like to do something simple yet I''m confused.
Lets say I have a table with 2 fields: rank, updated_at.
I would like to show all records matching this condition:
rank = rank ? (Time.now.to_time ? Updated_at.to_time)
As you can see this is supposed to be a calculation on the field.
How do I write a query to show this?
