I am trying to disable the parts of rails that i'm not using in my application, such as ActionMailer. Ib my application.rb, I made the following change
require "action_controller/railtie"
require "action_mailer/railtie"
#require 'rails/all'
And my app works fine. Now when I go and comment out the 'require "action_mailer/railtie"' line, I get the following error. I don't haveany mailers installed, so what's going on?
Thanks

Be careful, config.frameworks is deprecated in Rails 3!
The error you've got is coming from the #18 line of the file development.rb :
config.action_mailer.raise_delivery_errors = false
Since you do not require it anymore, config.action_mailer is undefined. You just have to comment the line and you will be fine.
In application.rb
config.frameworks -= [:action_mailer]

Is the problem caused by the the version of rails I am using or the version of skylight or something else entirely?
I am using ruby 2.4.6p354 and rails 3.2.22.5
I have installed and tried to switch to rails 4.2.0 but that doesn't seem to be working, I think because in the gemfile there is a pessimistic version constraint of gem "rails" ,"~>3.2" but I could be completely wrong. I have been told not to change the gemfile.
Check first line in error backtrace. You dont have /config/database.yml in your project
No such file or directory # rb_sysopen -
/Users/bena/Documents/repos/ben-repos/mapknitter/config/database.yml
(Errno::ENOENT)
Make sure you install everything from Prerequisites and simply follow Installation guide

The thin server seems to be working fine. Would appreciate any help .
I'm using ruby -v 2.2.2p95 and rails 4.2.2
UPDATE:
I do not think that it is with either the private_pub gem or the Sync gem(I tried using Sync just to make sure). Its still showing the same error. Since it says YAML is an uninitialized constant, i checked the function storing the YAML load and it looks like the following:
#.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/sync-0.3.5/lib/sync.rb
def load_config(filename, environment)
reset_config
yaml = YAML.load(ERB.new(File.read(filename)).result)[environment.to_s]
raise ArgumentError, "The #{environment} environment does not exist in #{filename}" if yaml.nil?
yaml.each{|key, value| config[key.to_sym] = value }
setup_logger
if adapter
setup_client
else
setup_dummy_client
end
end
Why doesn't ruby recognize that YAML?
Private Pub does not work with Rails 4. It has been forked to this gem:

I guess the issue is in the line 8 of config/environment.rb but can not find with the right fix. Is it possible that environment.rb should be included in 'config/environments/'?
The article states that you should put some code in:
config/environments/[environment].rb
Where [environment].rb is meant to signify one of the following files:
config/environments/development.rb
config/environments/production.rb
config/environments/test.rb
You could also put the code in config/application.rb if you want the same settings across your different environments.
The lines of code shown start with config.*, and they should be placed inside the Rails.application.configure do block.
config/environment.rb in a typical Rails 4 application is just a require and Rails.application.initialize!, and should not need modification.
If you have config.xxx in environment.rb
delete it and add these into development.rb:
Rails.application.configure do
config.xxx
end
I have also faced such an error(
NameError: undefined local variable or method `server' for main:Object
from (irb):1
from C:/RailsInstaller/Ruby2.2.0/bin/irb:11:in `<main>'),
)
maybe its because I am a Newbie in ruby on rails. hence instead of starting the rails server from direct command line I tried it to start from inside of IRB hence I got that error.
when I came out of IRB and started the server again from CMD it started smoothly.
I am using rails version 3.2.6 and i recently downgraded from 4.0 because i wanted to work on a 3 version environment because the tutorial im following they are using version 3.
I am on a windows 7 machine and this is what i have done so far.
i first did gem install rails -v 3.2.6
then i did gem uninstall rails, and chose the version i wanted to install.
i then downgraded the gem that were dependent on rails version 4 and i was not getting any errors when running bundle install.
now when i try to do rails s to see what broke on my page the server never starts and i get a bunch of file names:
=> Booting WEBrick
=> Rails 3.2.6 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

i know this might be a bunch of garbage to some, but if someone could help me that would be awesome. if you need more information, please let me know.
thank you in advance.
Since i am using rails on windows, RVM does not work, so i used the pik gem and with that i changed my environment to 3.2.6 and then it worked fine.
I update my Rails version 3.2.3 to 3.2.6. After running the server getting following error:
=> Booting WEBrick
=> Rails 3.2.6 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

This is because Rails 3.x has problem with Ruby 1.9.1. Try updating your Ruby to 1.9.3.

Do you have any observers? If so make sure that they inherit from ActiveModel::Observer. If they are custom classes, make sure they include Singleton module.
