Problem getting ar_mailer/ar_sendmail working on new server - ruby-on-rails

Hey all. I've got a new app up and running on a new ubuntu server. It's working fine generally but i can't get ar_sendmail working. I'm following the instructions on this page:
http://www.ameravant.com/posts/sending-tons-of-emails-in-ruby-on-rails-with-ar_mailer
The setup is all done, ie i can "deliver mails" which just saves records in my Email table. Now i want to get the ar_sendmail daemon running to actually send them. (so i'm at 'Running ar_sendmail in daemon mode' in that web page).
First thing:
ar_sendmail --mailq
>>ar_sendmail: command not found
Ok...so, where is ar_sendmail? I have a look and there's an ar_sendmail file in the bin folder of the ar_mailer plugin, so i add the location of that to my path. I don't know if this was the right thing to do or not.
Ok, so try again.
ar_sendmail --mailq
/var/www/apps/millionaire/vendor/plugins/ar_mailer/bin/ar_sendmail:3:in `require': no such file to load -- action_mailer/ar_sendmail (LoadError)
from /var/www/apps/millionaire/vendor/plugins/ar_mailer/bin/ar_sendmail:3
hmm. Here's the offending file, there's not much there.
#!/usr/bin/env ruby
require 'action_mailer/ar_sendmail'
ActionMailer::ARSendmail.run
ok...so it literally is just trying to require this and can't find it. The file, action_mailer/ar_sendmail.rb is in the ar_mailer plugin, in it's lib folder. So, given that it's being called from inside the plugin, it should be able to see this right?
I've got a feeling that i'm way off the track here and have missed something simple. Can anyone set me straight? I'm using rails 2.3.4 in case that's relevant.
EDIT - i just realised something kind of dumb: when i call ar_sendmail from the command line like this, i'm just loading that one file, which doesn't know where it's supposed to look for the rest of the stuff, i think. Which really makes me think that i'm not trying to run the right thing. Is the ar_sendmail daemon a seperate program altogether, that i would get with apt_get or something?
EDIT2 - i made some progress by installing the ar_mailer gem (which the guide said i shouldn't do) and that does seem to run. It's sending some mail request somewhere and clearing the Email table of pending emails. Running ar_sendmail in -ov (oneshot verbal) mode i see it report this for example:
sent email 00000000019 from from#address.com to to#address.com: #
So, it actually looks like it's working now and i just need to set up the ACTUAL THING WHICH SENDS EMAILS. sigh. still grateful for any advice.
thanks, max

What you need is an smtp server. Checkout www.sendgrid.com.

Issue with Rails Generator Building a Plugin

I am building a Rails plugin for an application at work.
I want to extract logic that was used in multiple locations, but implemented slightly differently, and add new features needed without doing it 2-3 times over.
I've never build a gem, but according to what I was reading it is possible to use rails generate.
However this has not been the case for me.
Running rails g model Something stuff:type:
First interesting thing is that it is generating mini test stuff when I explicitly told the plugin not to use mini test (using Rspec).
Then looking in my folder structure for the plugin, no db/ folder, nothing added to app/models/, and no test/ folder:
Running the command a second time reveals to me that the files are indeed created:
My questions are:
Where is this stuff going? Can I even find out?
Has anyone encountered something similar? Is it due to a misconfiguration, or bug? Essentially, what's happening?
I would truly appreciate any advice or suggestions!
EDIT #1
Forgot to mention that I checked within the spec/dummy application in case things were being created there, and it is still empty as I left it.
EDIT #2
So I found where the files were by using the find command:
And yeah it added the files to my home folder...
At least now I can just paste them in the right location, but obviously this is bizarre and I'd like to get this resolved, figure out what is going on.
Okay so turns out that yes you may use Rails Generators when building a gem. Also, the generated files will not be placed inside the dummy application unless you are in that directory.
Everything is working as expected on a different computer.
That stuff is going into dummy app that is usually located in test/dummy. In your case, it seems to be located in specs/dummy.
Yeap and nope. That's not misconfiguration.

ruby on rails unable to find interface that appears to be proplery defined

I'm brand new to ruby on rails and trying to run an application developed by others. I downloaded it from SVN it running yesterday, but today when I try to run it the first attempt to access the site's home page I get the message:
expected .../app/helpers/interface/table_helper.rb to define Interface::tableHelper.
.../lib/active_support/dependencies.rb:452:in 'load_missing_constant'
This file exists, and properly defines the tableHelper interface. Since I was able to run the program when I was setting it up yesterday, and others can run it without issue, I assume the problem I'm seeing is caused by an incorrectly set up environment rather then bad code somehow.
Can anyone suggest what I might try to figure out why rails can't seem to detect a properly defined interface?
If you were able to run the program once, perhaps something got screwed up? Have you made any changes to the code?
Alternatively, try stopping and restarting the server.
Also: what's the application? Maybe we can look at the codebase...

Newbie help with Rails/Ruby. Totally lost! (Mongrel related, I think) 503 Errors

I am on the verge of actually hiring someone to fix this
for me, but I hope it doesn't come to that.
I have no experience with Rails/Ruby, but I do know my way around
computers in general.
I have two domains on one server (Hostingrails, I am beginning to hate
them more and more these days).
My secondary domain works 100% fine.
But for the past few days, my primary domain has not been working, it
has been giving me 503 Errors. I've opened a ticket regarding this, and
they told me to SSH into my server and reset "Mongrel". I've done this
using the code they gave me; "mongrel_rails start -d -e production
-p13930"
It seemed to have worked, but the problem was still there. The log says
the error is something about:
"require': no such file to load -- dispatcher (LoadError)"
I've re-opened a ticket concerning this, and Hostingrails basically told
me that it is not their problem anymore and that it's solely up to me to
fix it. Brilliant.
So I spent a good part of the day looking and changing things around
through SSH (probably wasn't the greatest idea) but I still keep getting
503'd on my website.
However, I recently found out that my index file HAS to be index.html,
or it will not render the page. index.htm or index.php will result in a
503. If I set the index page to index.html, it worked. Which is strange,
my htaccess file allowed for all.
Another problem, I think I have inadvertently changed something in my
settings while I was SSH'd in. When I do "bundle install" it installs
the gems into my own private webspace, for example /home/mywebsite. But
I believe on my shared plan, all the rails/ruby/gems etc are all under
/usr/local/rvm/gems/ruby-1.9.2-p0/ which I don't think I have access to.
How do I change the directory to the default one? For example, before
the error log said:
/usr/local/rvm/gems/ruby-1.9.2-p0/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:239:in
`require': no such file to load -- dispatcher (LoadError)
Now it says:
/home/mysite/.gems/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:239:in
`require': no such file to load -- dispatcher (LoadError)
I think that's everything for now. Here are the rails installed on my
server by the host:
Installed at (3.0.0): /usr/local/rvm/gems/ruby-1.9.2-p0
(2.3.8): /usr/local/rvm/gems/ruby-1.9.2-p0
(again, I think my mongrel is looking in the wrong place, as my gems are
now being installed into /home/mywebsite/ instead of
/usr/local/rvm/gems/) Is it possible to someone reset the settings I've
changed back into my host's default one?
Would anyone be willing to take the time and try and fix this with me? I
am pretty annoyed at Hostingrails, since I didn't do anything to create
this problem, and they are outright refusing to help me. Why is my
primary domain getting 503 errors when my secondary domain works fine?
Mongrel is not compatible to ruby 1.9.2. You need use a fork of mongrel to use it https://github.com/kyusik/mongrel_cluster
I advice you to user thin/passenger or unicorn instead of mongrel.
I found a little blog post about problem with Mongrel and ruby 1.9.2 http://xaop.com/blog/2010/08/04/deploying-rails-3-on-ruby-1-9-2/
Maybe you could try using Ruby 1.8.7 - it causes less trouble in general at this time.
Not an answer to your question in particular, but if you're new to Ruby and Rails, then hosting your own stuff can be a daunting task.
Instead, try Heroku - simply push your Rails app to Heroku with git and you're good to go. They support custom domainnames for free.

rails console doesn't load

Today, for no reason, my rails(2.1.0) application is very slow or even not responding.
It happens intermittently.
So sometimes it works but again it doesn't work.
When it doesn't work, I can't even load 'script/console production'.
I want to know where it's stuck.
How do I load console step-by-step so that I can know which part causes the problem?
Thanks.
Sam
You could be running out of memory on your server and so the machine can't respond to you. If you are running mongrel then get monit onto it to limit the memory it can use and restart where necessary.
If you are using Passenger, try limiting the amount of instances, and if you have already done that look up a script that kills passenger instances when too big via a cron job.
If it's not a memory issue then I'd probably need more information.
If you are able, try temporarily removing all plugins/gems and see if the app will boot. One of those is likely the problem.
The script/console file contains this.
#!/usr/bin/env ruby
require File.dirname(__FILE__) + '/../config/boot'
require 'commands/console'
You can find the commands/console file here for Rails 2.1.
I recommend loading up irb and trying to load your app from there.
require 'config/boot'
If that works, then try stepping through the rest of the mentioned commands/console script to find out which part is the problem.
If the boot file won't load, take a look at that config/boot.rb file to see if you can determine which part isn't working. Good luck!
When all else fails, you should be able to use strace to debug what the script/application is actually doing. Note that this should only be one of the last resorts as it produces extremely verbose information (and also mostly limited to I/O actions).
Try using 'strace script/console production' for example

Not getting emails from ExceptionNotifier

I followed this tutorial on configuring the Rails plugin ExceptionNotifier.
I know that I have ActionMailer configured correctly because I am getting mail from other forms. I even have local_addresses.clear set so that it should be delivering mail no matter what.
I am using Apache with a mongrel_cluster running in the backend.
What am I missing?
You're using the SVN version of the plugin, which is probably unmaintained. Latest version can be found here.
Second thing which you can do is check the production log. Mailings get written to the log, so you'll see if Rails ever even tried to send it. If there are no entries, that means things are silently failing, which probably happens because -- for some reason -- exceptions are not caught properly.
If you added your ExceptionNotifier configuration information (your email address, etc.) into config/environment.rb, did you add it within the Rails::Initializer block or did you add it at the end of the file?
The tutorial you linked to doesn't specify where in the environment file to put the configuration information. The tutorial I followed (which might have been this one) does specify to put it outside the block.
Which things go inside that block and which outside is, frankly, still a little mysterious to me. But I thought this might answer your specific question.
Check your production log, exceptions can be throw in side the exception_notifier plugin, which prevent it from sending mails
