[Rails] Re: RoR with integrated windows authentication
Hey Alpha, As radhames brito pointed out, you can use a plug-in for LDAP authentication with Devise (a popular authentication system) to facilitate authentication with ActiveDirectory. I had to build a few systems like this a couple years ago, and at the time all I had available was a simple LDAP gem to facilitate communication. From an overview perspective, it's pretty simple. Your web application can accept username/password parameters, then ask your AD server to authenticate that user via a standard LDAP connection using a gem like ruby-net-ldap. The server responds, and your application can act accordingly. Implementation-wise, AD is Microsoft's LDAP system; you can interface with it pretty-much just like any other LDAP server, though I believe it has some unique qualities that make it a little bit special. One tool I found absolutely invaluable when doing this before was Apache's LDAP tool, Apache Directory Studio - http://directory.apache.org/. It can form a connection to your AD server and let you discover all the hidden properties of tree nodes that Microsoft's built-in AD browser won't tell you. You may need that when figuring out which tree to use when authenticating users (depending on how your LDAP setup works) or other potentially valuable items stored therein. Unfortunately, I can't comment on how Devise does LDAP authentication as I haven't used it before (I don't think it existed at the time I had to build the equivalent a few years back). I'd recommend trying to use it first, and if you can't quite get that working, you can go deep dive and brew your own. Generally speaking though, using a standardized and properly maintained authentication system like Devise is a better way to go, so I'd recommend that approach starting out. I hope this helps you at least get an idea of where to start. Good luck!

I want to build the new ticketing system with Rails as I believe it to be a much cleaner long term solution, and add to that I don't care for ASP and how it handles sessions. I've searched long and hard and a lot of posts and information out there are pretty out dated in terms of NTLM or (integrated windows authentication) as it's now called working with Rails. I will not be using IIS thankfully and would rather go an Apache route with a mod to handle initial authentication through windows active directory. We use IE8 and it should pass through perfectly. But, I need to know what I'm getting into and would like to look over as many resources as possible before I fully commit to this project. So, with that said, what resources am I going to need to work on this? I'm fully familiar with Ruby 1.8.7, 1.9.1, and 1.9.2 and Rails version 2.x and 3.x, including rails 3.1. I normally use apache + passenger + rails when going to production on a linux server. How would you approach this and what pieces would you opt for, given this scenario? And, any updated links on where to go with this?

[Rails] Rotating logs in Rails 3
It looks like there are two accepted ways of rotating log files on
production, but most of the discussion I've found is a couple years
old. Does anyone have an opinion on which of these methods is better
for a Rails 3 app on CentOS? Which method are you using and what are
the drawbacks of it?
1) Inside of Rails:
In config/environments/production.rb, put in something like this line:
config.logger = Logger.new(config.log_path, 50, 1.megabyte)
2) Using logrotate:
create the file /etc/logrotate.d/passenger and put something like this in it:
/home/deploy/app/shared/log/*.log {
daily
missingok
rotate 30
compress
delaycompress
sharedscripts
postrotate
touch /home/deploy/app/current/tmp/restart.txt
endscript
}
Thanks!

[Rails] Re: shared primary key (using the primary key as a foreign key for has_one association)
It is indeed redundant to have both #set_primary_key and the :primary_keyoption w/in your #has_many (or #has_one) calls. You can safely ignore that aspect of my prior posts :). The real code I yanked my examples from actually has a table with a primary key named ID (so set_primary_key ID) but has another column UserID (that is also unique and *could* have been the primary key instead; crazy old db) that for all relationships is treated as if it were the primary key. So, in reality my model is more like this: class User ActiveRecord::Base set_table_name tblUser set_primary_key ID has_many :comments, :primary_key = UserID, :foreign_key = PosterID end That's what I get for not simply copy/pasting (then nuking irrelevant details) and hand-coding my example from memory. Anyhow, your other observation is also dead on. Creating an association on a model doesn't require you to create the inverse association on the other model. P.S. the reason i am torturing Rails like that is that it also has a convention that it should obey the human. Seriously, i just want a nice and clear structure of my database, which would be editable by hand (it is not going to be big), and to use Rails just for a simple interface. While I always follow rails conventions when possible (and recommend others do too), I also like to torture frameworks to see how flexible they are. After all, there are always occasions where it becomes necessary, such as in my instance where I have to work off of a legacy database that is still concurrently being accessed by legacy software. On the side, however, I've instantiated a dozen smaller toy or utility rails apps where I've followed the conventions and idioms religiously to great effect.

Re: [Rails] Re: Rotating logs in Rails 3
Okay, I'll bite and give my $0.02.
Method #1 Pros and Cons:
Con: I don't like the application code to be responsible for log rotations.
It feels like this should be a system administrative task.
Pro: Easy to set up and no need to drop a logrotate config in /etc on
deployment
Agreed...
Method #2
Con: Deployment requires another external step (configuration external to
the application code itself)
Pro: From a sysadmin point of view, I keep all my log rotation
configuration in one place (as it ought to be).
My Preference
Method #2: use capistrano or other scripted/automated deployment tool to drop
(or update) a logrotate config in your /etc/logrotate.d/ directory to
overcome the downside of this method and you're golden.
One drawback to this is /etc/logrotate.d is usually owned by root... do you
want capistrano to be able to write to root protected directories? That opens
a door for someone to put in a postrotate script that does all kind of nasty
things as root :(
If it was me, I'd install a rails logrotate file *once* that covered all your
deployed applications... something like the below. This way it's installed
once, and never needs to be installed again for any new applications. As long
as you make sure the regex's match all your apps anyway :)
/home/philip/apps/*/shared/log/*.log {
daily
missingok
rotate 30
compress
delaycompress
notifempty
create 640 philip philip
sharedscripts
postrotate
if [ -f `. /etc/apache2/envvars ; echo
${APACHE_PID_FILE:-/var/run/apache2.pid}` ]; then
/etc/init.d/apache2 reload /dev/null

[Rails] SSL Requirement double POST from IE on expired certificate
This is really weird.
User testing in my staging environment where the SSL certificate for
the secure domain has expired. Here is the scenario:
User fills in a form containing a serial number which has to be
unique. which I use validate_uniqueness and a unique index on the
mysql db (belt and braces).
The create action is fired in the controller to do the insert on the
model. So far so good.
The next controller new action is protected by SSL and this domain
has an expired certificate and IE8 puts up the expected warning which
the user will ignore.
The original POST and the create action is invoked again, to which the
model says that it has a duplicate serial number. Why is the POST
sent again by the browser?
Doesn't happen on any other browser. I could install another valid
test certificate but it is a real pain to do (too many sleazy sales
guys call and they do not understand what they are selling!). Any
other suggestion as to how to avoid this happening and how I can write
some tests for this!

[Rails] Strange issue with Rails middleware, Warden and missing path paremeters
Hey, this started as OmniAuth issue and is pretty well document here: https://github.com/intridea/omniauth/issues/#issue/239/comment/917065 If you have a bare Rails app with Devise gem (Warden itself would probably be enough), add the following middleware to simulate OmniAuth behavior: class BreakApp def initialize(app) @app = app end def call(env) @app.call(env.dup) # call 1 @app.call(env) # call 2 end end and call Warden in ApplicationController before_filter e.g.: request.env['warden'].authenticate(:scope = :user) then params[:controller] and params[:action] are missing. If you remove the before filter *or* change the first call in the middleware to @app.call(env) (without #dup) it works fine. I prepared a sample app to show this issue: https://github.com/szimek/omniauth_dynamic_providers_bug I have no idea if this issue is caused by Rails or Warden code. Any ideas why path parameters are missing and how to fix it are welcome :) Cheers, Szymon -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] why does my method return an error if argument is not a number?
Hey all,
I get the following error message:
ActionView::TemplateError (class or module required for rescue clause)
in app/vie$ app/helpers/format_helper.rb:116:in `divide_numbers'
Basically I have a field in database called Student Fails and I populate
fields with data. Sometimes the value can be empty - not null, not
integer, just empty because when user updates record they clear out
field and update it. First in my progressbar file I render a partial
called progressbar_item, passing in the string to the partial in render
method as well as data parameters that I can use in my progressbar file:
= render dashboard/progressbar_item.html, :actual =
@student_counters[:student_failed], :expected =
cu.context.expected_student_failed, :title = Student Fails
Now with the data parameters available in my view, I call the
divide_numbers method with the values of those parameters so if
expected_student_failed was an empty value in database, that empty value
gets passed as the second argument:
= render dashboard/progressbar.html, :value =
divide_numbers(actual.to_f, expected), :text = #{actual} /
#{expected}
Then the method is executed in format_helper:
def divide_numbers(x, y)
result = x / y
result.to_s == 'NaN' ? 0 : result
rescue 0
end
If y is nothing (empty), the error occurs. If y is an integer the error
doesn't occur. Doesn't this line take all non numbers like empty and
convert it to integer 0:
result.to_s == 'NaN' ? 0 : result
If that's the case, then why do I get the error?
Will I be forced to do this (i haven't tested this yet but I presume it
would work):
def divide_numbers(x, y)
result = x / y
if result.nil?
result.to_s = 0
else
result.to_s == 'NaN' ? 0 : result
end
rescue 0
end
Thanks for response.

Basically I have a field in database called Student Fails and I populate
fields with data. Sometimes the value can be empty - not null, not
integer, just empty because when user updates record they clear out
field and update it. First in my progressbar file I render a partial
called progressbar_item, passing in the string to the partial in render
method as well as data parameters that I can use in my progressbar file:
= render dashboard/progressbar_item.html, :actual =
@student_counters[:student_failed], :expected =
cu.context.expected_student_failed, :title = Student Fails
Now with the data parameters available in my view, I call the
divide_numbers method with the values of those parameters so if
expected_student_failed was an empty value in database, that empty value
gets passed as the second argument:
= render dashboard/progressbar.html, :value =
divide_numbers(actual.to_f, expected), :text = #{actual} /
#{expected}
Then the method is executed in format_helper:
def divide_numbers(x, y)
result = x / y
This line will raise an error if y is nil or blank... It won't even get to
the next line.
result.to_s == 'NaN' ? 0 : result
rescue 0
end
If y is nothing (empty), the error occurs. If y is an integer the error
doesn't occur. Doesn't this line take all non numbers like empty and
convert it to integer 0:
result.to_s == 'NaN' ? 0 : result
If that's the case, then why do I get the error?
Will I be forced to do this (i haven't tested this yet but I presume it
would work):
def divide_numbers(x, y)
result = x / y
if result.nil?
result.to_s = 0
else
result.to_s == 'NaN' ? 0 : result
end
rescue 0
end
Thanks for response.

That's not legal ruby - where you've stuck a 0 it's expecting a class
name (which sort of exceptions the rescue clause should handle).
You may be mixing things up with the one liner do_foo rescue 0. Also
floats have a nan? method which would be a little nicer than that
string comparison you have there
If y is nothing (empty), the error occurs. If y is an integer the error
doesn't occur. Doesn't this line take all non numbers like empty and
convert it to integer 0:

Not quite. That will only coerce NaN to 0, but it wouldn't do anything
to Infinity, and of course you wouldn't even get to this line if y was
something such that x / y was meaningless (ie y is not coercible to a
numeric value). NaN isn't a placeholder for anything that isn't a
number but for specific situations where it isn't possible to come up
with a more meaningful answer (eg 0.0/0 )

[Rails] Routes and REST Issue
Hi all,
A relative newcomer to routes here - I have a controller on which I
would like to be able to specify only a couple RESTful operations (my
example is for a RESTful user sessions controller, where it only makes
sense to (1) create a session, and (2) destroy a session).
Using 'resources' on a controller in the routes file gives all seven
methods so I'm not using that; I only need the two above, so my routes
file looks like this:
match 'sessions' = 'sessions#create', :via = :put
match 'sessions' = 'sessions#destroy', :via = :delete
Essentially I want a user to send a put (this is an idempotent
operation) to the sessions collection URL, with a params hash of
username and password. And calling delete on the same URL will log out
the session.
However, my RSpec test, which looks like this:
describe PUT 'new' do
# (NB this user is created in the 'before' method)
it should be successful do
put 'new', {:name = 'a_user_logging_in', :password =
'a_password'}
response.should be_success
end
it should not be successful with a wrong username or password do
put 'new', {:name = 'an_incorrect_user', :password =
'a_password'}
response.should_not be_success
end
end
Does not pass as the routing fails! Here is the RSpec error:
Failure/Error: put 'new', {:name = 'a_user_logging_in', :password =
'a_password'}
ActionController::RoutingError:
No route matches {:name=a_user_logging_in,
:password=a_password, :controller=sessions, :action=new}
So clearly I've made an error here somewhere with my Routes, can someone
help me achieve what I'm after (i.e. just a put and delete on a
collection, which calls create and destroy on the controller?).
Many many thanks for your kind help,
- Nex

Making a create route does not give you a route for 'new' -- you'll need to
create both.
You can also do:
resources :sessions, :only = [:new, :create, :destroy]
if you like.

[Rails] undefined method load_paths for ActiveSupport::Dependencies:Module Error
I'm writing a Rails plugin from scratch and recently generating models
inside it.
In fact, i'm trying to follow the guide from
http://guides.rubyonrails.org/plugins.html
so i used the following code taken from this site in order to make the
models appear like files in the main app directory (as it was said)
this is the code:
%w{ models }.each do |dir|
path = File.join(File.dirname(__FILE__), 'app', dir)
$LOAD_PATH path
ActiveSupport::Dependencies.load_paths path
ActiveSupport::Dependencies.load_once_paths.delete(path)
end
__
When i run 'rails console ' this error appear
undefined method `load_paths' for ActiveSupport::Dependencies:Module
(NoMethodError)
thanks for your help

[Rails] Debugging help needed
I have an odd problem I'm stumped on how to debug. I'm running Rails 2.3.5 under rvm. I'm doing a new test that *should* work but it does not. My test is I clear my database so it is empty and then start a request. Its a complex application that interacts with another legacy server fetching things, putting them into the database, and then presents a final rendering. I make the request and I see my ruby process (using top) consume cpu of varying degrees (16% up to 50%). Then it goes to 100% and sits there. At that point, my log file stops growing. The last few entries are: Cached fragment miss: views/PEDZ,S,165,405-1301358353.887364-qs (0.3ms) Rendered retain/qs/_qs_row (990.1ms) Rendered layouts/shared/_doctype (0.3ms) Rendered layouts/shared/_header (1.6ms) Rendered layouts/shared/_body (0.8ms) But I do not have the Completed entry that usually ends each request. So it is stuck somewhere after most of the rendering, perhaps in the sending stage. And that is what I need help with. How do I find where it is getting stuck at?

[Rails] recaptcha displaying weirdly
Hi List, I've followed and read several guides for getting recaptcha working with a site but I keep coming across this problem.
