Not sure what is going on here ...
Thank you so much

Like house9 commented above, I basically commented out the entire ruby file that was causing me the problems.
And then I had a problem starting the Rails server because it couldn't find a database. So it threw an ActiveRecord error:
ActiveRecord::StatementInvalid in PostsController#homepage
Mysql2::Error: Unknown column 'posts.status' in 'where clause': SELECT
posts.* FROM posts WHERE posts.status = 'PUBLISHED' AND
posts.post_type = 'About' AND (title LIKE 'About Ourgoods%') ORDER BY
created_at DESC LIMIT 1....
After connecting a .sql file that I had to the Rails app (following instructions from: How do I connect a mysql database file to a local ruby on rails application), and running rake db:migrate, I finally got rails s working!

Your error message is saying it all:
NoMethodError: undefined method `value' for nil:NilClass
You are trying to call value on nil at some point. And, this is probably happening here:
# Specify request parameters
params = {
auth_token: auth_token,
anchor: Anchor.first.value, # this is the line that's creating problem
source:"CRAIG",
category_group: "VVVV",
category: "VAUT",
'location.country' => "USA",
retvals: "location,external_url,heading,body,timestamp,price,images,annotations"
}
When you call this: anchor: Anchor.first.value for the very first time, your Anchor.first is nil and so you are trying to call: nil.value and that's where your rake task fails with the specified error message.
Make sure you have populated the database table (anchors) so that when you call Anchor.first, you don't get nil.
Another approach to avoid this issue would be to use try:
anchor: Anchor.first.try(:value)
That way, your rake task won't fail even if Anchor.first returns nil.

Resque with Rails 3 + Heroku + RedisToGo giving Postgresql error

I'm writing an app which needs to send many emails and creates many user notifications because of these emails. This task produces a timeout in Heroku. To solve this, I decided to use Resque and RedistToGo.
What I did was to send the email (it's actually just one email because we use Sendgrid to handle this) and create the notifications using a Resque worker. The email is already created, so I send its id to the worker, along with all the recipients.
This works fine locally. In production, unless we restart our app in Heroku, it only works once. I will post some of my code and the error message:
#lib/tasks/resque.rake
require 'resque/tasks'
task "resque:setup" => :environment do
ENV['QUEUE'] = '*'
end
desc "Alias for resque:work (To run workers on Heroku)"
task "jobs:work" => "resque:work"
#config/initalizers/resque.rb
ENV["REDISTOGO_URL"] ||= "redis://redistogo:some_hash#some_url:some_number/"
uri = URI.parse(ENV["REDISTOGO_URL"])
Resque.redis = Redis.new(:host => uri.host, :port => uri.port, :password => uri.password)
Dir["#{Rails.root}/app/workers/*.rb"].each { |file| require file }
#app/workers/massive_email_sender.rb
class MassiveEmailSender
#queue = :massive_email_queue
def self.perform(email_id, recipients)
email = Email.find(email_id.to_i)
email.recipients = recipients
email.send_email
end
end
I've got an Email model which has an after_create that enqueues the worker:
class Email < ActiveRecord::Base
...
after_create :enqueue_email
def enqueue_email
Resque.enqueue(MassiveEmailSender, self.id, self.recipients)
end
...
end
This Email model also has the send_email method which does what I said before
I'm getting the following error message. I'm gonna post all the information Resque gives to me:

According to this, the first argument is the email id, and the second one is the list of all recipients... exactly as it should be.
Can anyone help me? Thanks!
I've run into the same problem. Assuming you're using Active Record you have to call ActiveRecord::Base.establish_connection for each forked Resque worker to make sure it doesn't have a stale database connection. Try putting this in your lib/tasks/resque.rake
task "resque:setup" => :environment do
ENV['QUEUE'] = '*'
Resque.after_fork = Proc.new { ActiveRecord::Base.establish_connection }
end

Rails does not read the code from the file enviroment.rb when I use the production environment

I am using rails version 3.0.3.
If I run the server in the development environment, everything works ok, but when trying to run in a production environment then rails skip read the code from the file /config/ enviroment.rb.
I have the following error:
=> Booting WEBrick
=> Rails 3.0.3 application starting in production on http://0.0.0.0:3000
=> Call with -d to detach

Many thanks for help
.. sometimes, ruby takes a wrong turn when deciding where to look for a constant. You defined the constant GRUPY_PRODUKTOWE globally and you probably access it within the Product model with just "GRUPY_PRODUKTOWE". Try "::GRUPY_PRODUKTOWE" so it knows to look for it in the global scope.

Rails 3: Mail::Message cannot be delivered after serializing

I want to serialize a Mail::Message object in order to store it in the database and send it later.
My first attempt was to use the built-in serialize method of ActiveRecord like this:
class Email < ActiveRecord::Base
serialize :mail
# ...
end
Unfortunately, trying to save the record resulted in an exception
> foo.save
ArgumentError: wrong number of arguments (1 for 0)
from /home/akrueger/.rvm/gems/ruby-1.9.2-p180/gems/mail-2.2.19/lib/mail/message.rb:1714:in `to_yaml'

(...)
So I simply created a custom accessor using the to_yaml / from_yaml functions of Mail::Message. But now I experience this strange behaviour:
mail_original = UserMailer.user_welcome_email(#user)
=> #<Mail::Message:93415800, Multipart: false, Headers: <From: (...) >, <To: (...) >, <Subject: (...) >, <Mime-Version: 1.0>, <Content-Type: text/plain>>
mail_clone = Mail::Message.from_yaml mail_original.to_yaml
=> #<Mail::Message:92940980, Multipart: false, Headers: <Date: (...) >, <From: (...) >, <To: (...) >, <Message-ID: (...) >, <Subject: (...) >, <Mime-Version: 1.0>, <Content-Type: text/plain>, <Content-Transfer-Encoding: quoted-printable>>
mail_original.deliver
=> #<Mail::Message:93415800, Multipart: false, Headers: <Date: (...) >, <From: (...) >, <To: (...) >, <Message-ID: (...) >, <Subject: (...) >, <Mime-Version: 1.0>, <Content-Type: text/plain>, <Content-Transfer-Encoding: quoted-printable>>
mail_clone.deliver

Any idea on how to solve this problem? Why does serializing the object to yaml make the Message object undeliverable? Is there maybe another method to properly serialize the Message object to send it later?
I realized the mail_clone object did not have proper delivery settings, which caused the failure of the deliver call. Browsing through the Rails sourcecode, I found the following solution:
mail_clone = Mail::Message.from_yaml mail_original.to_yaml
ActionMailer::Base.wrap_delivery_behavior mail_clone
mail_clone.deliver
So this might be a way to serialize the Mail::Message object:
class Email < ActiveRecord::Base
def mail
#mail_cached || begin
m = Mail::Message.from_yaml(self.read_attribute :mail)
ActionMailer::Base.wrap_delivery_behavior m
m
rescue
nil
end
end
def mail=(val)
#mail_cached = val
write_attribute :mail, val.to_yaml
end
# ...
end
Does specifying the class name help?
serialize :mail, 'Mail::Message'
