Hoping someone might be able to throw me a few clues on this one.
I'm working with lists of names a User (current_user) manages lists of
names, some male some female (scoped on m or f in gender), it's all set
up such that I can do things like this - all working out fine.
current_user.names.male
Actually - thinking it through this is an instance method I believe,
acts on an instance of a name. Kind of talking out loud here.

Actually, I'll try for the instance method for the male version in
name.rb..
def find_similar_male
# get all users
users = User.all
# get all male names
names = Name.male
# get the similar names
similar_names = []
# loop users...
users.each do |user|
# loop names
Hi Colin,
Sorry - just seen your question as I was writing my method above...
User has_many names
Name belongs_to User

Hi.
I have RoR app. It needs to use keepalive in its responses. It sits on
apache. I've configured apache and its serving static files from apache
with keepalive working, but dynamic pages generated by the RoR app are

Hello Jordan,
I am not quiet sure. This is how my model looks like
class Picture ActiveRecord::Base
has_attached_file :image,
:styles = { :medium =
300x300, :thumb = 100x100 },
I fixed it using old ways, changed migration file as shown
class AddImageColumnsToPicture ActiveRecord::Migration
def self.up
add_column :pictures, :image_file_name,:string
add_column :pictures, :image_content_type, :string
add_column :pictures, :image_file_size,
Is my proposed method (while probably not the most elegant) a reasonable
way of attacking the problem?

So the two 'harry's in your list are two different objects? Is that a
necessary part of your model?

I'm fairly new to the Rails community and recently faced a similar

provide the functionality you desire.
Secondly, there is a nice screencast at Railscasts.com that provides a good
introduction, however some of processes in
So I could put my code into another file foo.js and 'require' it in

I believe these other .js files would be in the assets directory to be

That is correct. The .js (or .js.coffee if using coffeescript) files should
be in app/assets/javascript/.
You could use require tree which is specified from the beginning and will
include all javascript files. I do prefer to require each file separately
though as it gives me more control.

If wasn't for the last 2 messages, the mention that you type this in

If you still want to use Aptana, you will need to change the shebang

Also ensure gems are installed with --env-shebang

I find it confusing, because the language in application.js indicates
that separate javascript files need only be included in that directory
and they'll automatically be compiled, while other sources say files

In fact application.js says not advisable to add code

And I'm also interpreting (don't) add code directly here as not to

But again other sources say to use require_tree to include separate

From what I can tell gradient descent is just math:

By the way... running bundle install --path vendor/cache on the

To get it to deploy I have to shell into the server, cd to
