[Rails] SMTP settings for action mailer
with rails 2.2.2 action mailer requires a valid ssl certificate
i have a question about routing
my smtp settings for my postfix are now
ActionMailer::Base.smtp_settings = {
:address => "smtp.mydomain.com",
:port => 25,
:domain => "mydomain.com",
:authentication => :plain,
:user_name => "mydomain_mai...@mydomain.com",
:password => "password"
}
both the email server and the rails app are on the same machine
if i don't have the address as 127.0.0.1
is it routing information through the internet instead of internally
in the machine?
if i use 127.0.0.1 i will get the ssl error because the host does not
match up.

[Rails] Actionmailer and postfix settings
Hi, I am having problems configuring my actionmailer to work with postfix. I followed this tutorial: http://howtoforge.org/virtual-users-and-domains-postfix-courier-mysql-centos5.1 and i got the server set up. at first i fixed the mail settings to work with gmail using this tutorial: http://www.danielfischer.com/2008/01/09/how-to-use-gmail-as-your-mail-server-for-rails/ and my app worked with gmail. but now i want it to work with my newly built email server. I read somewhere if your server has tls u have to do something special with actionmailer for it to work so i am relying on fischer's workaround. so i inputed this into the mailer.yml file that danielfischer created: :address: localhost :port: 25 :domain: localhost :user_name: mai...@mydomain.com :password: secret :authentication: :plain :tls: true Should i have used mydomain instead of localhost?

grocery_price = grocery.send(batch).price
if grocery_price
number_to_currency(grocery_price)
else
"NA"
end
end
def loop(func,matrix)
matrix.each { |matrix| display_price(@grocery,matrix) }

the "func argument" in the loop function is suppose to be
display_price but how do i put it in if the "batch" is the thing that
I want to be looped through?

[Rails] Re: nested array .select statment
ok i managed to get this out
smallest = x.min{|x,y| x[0] <=> y[0]}[0]
result = x.select{|g| g[0] == smallest}.map{|g|g[1]}
and it works
but the problem is when i apply it to my app
because [[1,"h"],[2,"g"]]
is actually [[groceries.price,"h"]]
and it gives
undefined method `[]' for #
meaning that theres something wrong with groceries.price
but in the migration file .price is specified to be
t.decimal :price, :precision => 8, :scale => 2
I don't understand why rails is giving an undefined method
when i subsitute in decimals for 1 and 2 in the array it is ok.
