The issue is that I should have to override lots of Model to support it.
Ex:
Model.create transaction_value: value
I would like something more elegant.

I am getting crazy about this problem... Basically pg compiles for my
system ruby (installed via apt-get), also compiles for my RVM ruby 1.8
BUT when I try to compile it for RVM ruby 1.9 it will fail!!! Why??
Error is always:
Can't find the PostgreSQL client library (libpq)

How about Linux/Ubuntu? Is Mac much better than Linux too?

You could start with a VM running Ubuntu to get started with Rails
development. A Mac would be far superior, but Ubuntu will get you started.
You can do Rails development on Windows, but you may have trouble with
certain gems.

From a purely RoR developer perspective Linux is good. Which you would
expect since most RoR applications are deployed to Linux servers - or
are you deploying to Windows servers. Its just that Macs are nicer :)
As to why your Windows system is slow for developing could be that you
have a crappy
class User
attr_accessor :id, :name
def initialize(id, name)
@id = id
@name = name
end
end
charlie = User.new(9, 'Charlie')
fred = User.new(1, 'Fred')
sally = User.new(3, 'Sally')
@users = [
fred,
fred,
fred,
sally,
charlie,
sally
]
user_counts = Hash.new(0)
Maybe this helps:

Hi,
I have a many-to-many relationship via a join table. When I attempt to
set the values (i.e. the relationship) in the join table via the Rails
console I get the following error, does anyone know what could be wrong?
Thanks.
Note: I have set attr_accessible -- see Grade model below.
Yep:
1.9.3p0 :005 module B
1.9.3p0 :006? def name
1.9.3p0 :007? puts 'b module'
1.9.3p0 :008? end
1.9.3p0 :009? end
= nil
1.9.3p0 :010 module C
1.9.3p0 :011? def name
1.9.3p0 :012? puts 'c module'
1.9.3p0 :013? end
1.9.3p0 :014? end
= nil
1.9.3p0 :015 class A

…looking for a module named Rendering in the ActionController
namespace, since that is the namesapce that Base is defined in???

Each user has a unique id, so what does that
Hi Javier..
I want to show all entries..they have different other attributes but the
same user (name)..thats why group_by is not what I can use.
Just want to mark them 'bold' ..so I need a true/false for every result
item..
Thanks so far..

I have a controller:
class HomeController ApplicationController
def index
end
def about
end
def contact
end
def terms
end
def privacy
end
end
My routes.rb has:
resources :home do
member do
get 'about'
get 'contact'
get 'terms'
get 'privacy'
Maybe it could be a inflection problem:
home.pluralize
homes
The convention is that a controller is the pluralized name of the model.

Thanks, that worked. Although it doesn't make sense, it isnt' a colleciton
so I guessed to use member.
BTW, how could I match this:
/home/some-name-here
Where 'some-name-here' is the parameter (id), and I want to call home#show
On Wed, Sep 19, 2012 at 9:56 PM, Fernando Almeida
You can use
match 'home/:page' = 'home#page' before
resources :homeafter
# home_controller
def page
# use params[:page]
end
Rails routes are matched in the order they are specified, so if you
have a resources
:photos above a get 'photos/poll' the show

this isn't advisable. home/:page will match home/1

i'm not saying that it won't work. i'm saying that it's not good practice.
i would've agreed
with your method if you added constraints to values of the :page parameter.
hummm... really, I agree with you.
