[Rails] Controlling concurrency
What do you think is the best way to manage concurrency in this (made up) scenario? 1) You are selling Orders for items of various ProductVariants, belonging to one Product 2) There may be an upper limit to how many Orders you can take for any given Product 3) For our example today, you can only accept three more orders for any combination of ProductVariants of a Product 4) Two users put in three Orders, at the same time It's in the realm of millisecond possibility, then, for this to happen: Person 1: Validate that 3 Orders can be made for Product 123 = true Person 2: Validate that 3 Orders can be made for Product 123 = true Person 1: Orders.create(:product_variant = 9); Orders.create (:product_variant = 8); Orders.create(:product_variant = 7) Person 2: Orders.create(:product_variant = 6); Orders.create (:product_variant = 5); Orders.create(:product_variant = 4) Oops! 6 Orders placed! What do you think is the best way to prevent overselling in this case? I've considered: * Table locking (sucks) * Setting a lock file per-Product (filesystem-y and not elegantly scalable past one machine) * Setting a lock variable per-Product in a memcached store * A single-worker queue that validates and processes orders in sequence * A per Product single-worker queue that validates and processes orders in sequence * Something I haven't considered?

[Rails] Complex forms: only one level of “arrayn ess” is allowed?
Hi all, I thought I was trying to do something rather simple, but it has caused me a lot of headaches. Here it is: - in my program: model_a has_many model_b. model_b has_many model_c. - in the user interface, I would like the user to be able to fill the information for one model_a, one or more associated model_bs (corresponding fields could be added with a set of links 'add/remove a model_b'), and for each model_b added, one or more model_c (with the same mechanism). Thanks to the great tutorial Handle multiple models in one form, it's easy to handle the first step (any number of model_b per model_a), but I can't get the second step to work. The natural indexing should (I think) be: model_a[model_b_attributes][][model_c_attributes][][an_attribute] But it doesn't seem to work. I read here http://guides.rubyonrails.org/form_helpers.html that only one level of “arrayness” is allowed and that I should use hashes instead, but I am not quite sure I understand how to do it. Do you have any idea? Thanks a lot PJ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Do you have any idea?
What that comment is saying is that you can replace an array eg
[a,b,c] with a hash eg {1 = a, 2= b, 3=c}
Generating those keys is up to your client side code, approaches
included using a number you increment or going for some unique thing
you generate on the spot (eg time in milliseconds concatenated with a
random number) so that you don't have to keep track of how many fields
and what not you have created clientside.

[Rails] Spreadsheet -avoid reading and writing from file how?
Hi
I am using http://spreadsheet.rubyforge.org/ in my application..Usage
like
book = Spreadsheet::Workbook.new
book.write #{RAILS_ROOT}/public/uploads/excel-file.xls
render :file = #{RAILS_ROOT}/public/uploads/excel-file.xls
headers['Content-Type'] = application/vnd.ms-excel
headers['Content-Disposition'] = attachment; filename=excel-file.xls
headers['Cache-Control'] = ''
In the above i am writing to a file in a location and then read.
My question is is there any method so that writing to a file can be
avoided ..Because if there are some 100 requests the file will be
overwritten(Am I right?) or if give seperate names for the files the
upload folder will grow..So is there alternative and i can read the same
content directly
Thanks in advance
Sijo

Also, in the scaffold edit page, the default edit method displays all the fields (including checkbox and radio buttons) as text_field(text box) with only single value.

[Rails] Re: SQL Server via DBI/ODBC configuration
Mike, in my experience this has been painful. Here's a few things to look for: First, make sure that TDS is set up fine. Verify it with this command: tsql -S server -U user -P password Make sure you have ruby-odbc to have ruby load the ODBC driver (think this could potentially solve your issue). My instructions on a fedora box are: RubyODBC: wget http://ch-werner.de/rubyodbc/ruby-odbc-0.9996.tar.gz tar -xvzpf ruby-odbc-0.9996.tar.gz cd ruby-odbc-0.9996 ruby extconf.rb make sudo make install Test it out again.

[Rails] Re: Controlling concurrency
If you positively cannot have overbooking (oops, airline talk) over-selling, then all your orders have to either lock a table (using the database to enforce serialization), or they have to be serially examined in someway, such as a single order FIFO queue. You could create an observer, for example, that monitors the creation of an order, checks to see if stock (tickets, seats, CD's, whatever) is available; and gracefully back-out an order that goes over. Personally, I would be tempted to try a simple solution, like a queue of some sort first, or perhaps an observer, rather than use the database. This is one of those cases where trying to optimize too early may hurt. A simple, single, global queue may be all you need. YMMV.

[Rails] [ANN] Rails plugin to improve log format
I have created a Rails plugin to improve the log file format. (It also
adds an optional “Exception” parameter to the warn() and error()
methods to print a stack trace automatically.)
It's available here:
http://github.com/pauldowman/better_logging
___Improved log format___
It adds severity level (with colour, if
ActiveRecord::Base.colorize_logging == true), hostname and process ID
to each log line, and it and adds warn() and exception() methods that
take an exception as an argument and print the stack trace.
For example, here’s how the default format looks:
Session ID: 7eeb00aa62b395698a28bf033e56b7c5
Parameters: {action=show, id=1, controller=people}
User Load (0.4ms) SELECT * FROM `users` WHERE (id = '1') LIMIT 1
User Columns (2.1ms) SHOW FIELDS FROM `users`
Rendering template within layouts/application
Rendering people/show
Rendered layouts/_head (3.1ms)
Rendered layouts/_navigation (2.2ms)
Adding Cache-Control header
Completed in 164ms (View: 116, DB: 21) | 200 OK [http://localhost/
people/1]
Here’s how the same thing would look with the better_logging plugin
installed in development mode (it looks best with a proportional
font). Note that the severity (INFO, WARN, ERROR, etc), is printed in
colour (if colour is enabled for the log, which it is by default in
development mode).
INFO Session ID: 7eeb00aa62b395698a28bf033e56b7c5
INFO Parameters: {action=show, id=1,
controller=people}
DEBUG User Load (0.4ms) SELECT * FROM `users` WHERE (id = '1')
LIMIT 1
DEBUG User Columns (2.1ms) SHOW FIELDS FROM `users`
INFO Rendering template within layouts/application
INFO Rendering people/show
DEBUG Rendered layouts/_head (3.1ms)
DEBUG Rendered layouts/_navigation (2.2ms)
INFO Adding Cache-Control header
INFO Completed in 164ms (View: 116, DB: 21) | 200 OK [http://
localhost/people/1]
And here’s how it would look with the better_logging plugin installed
in production mode, on a host named “akash”, with process id 27471:
akash.27471 13:27:04 INFO Session ID:
7eeb00aa62b395698a28bf033e56b7c5
akash.27471 13:27:04 INFO Parameters: {action=show,
id=1, controller=people}
akash.27471 13:27:04 INFO Rendering template within layouts/
application
akash.27471 13:27:04 INFO Rendering people/show
akash.27471 13:27:04 INFO Adding Cache-Control header
akash.27471 13:27:04 INFO Completed in 164ms (View: 116, DB: 21)
| 200 OK [http://localhost/people/1]
And here’s how it would look in production mode on a host with a long
name. This host name is “myreallybigserver-7.mydomain.com”.
igserver-7.27471 13:27:04 INFO Session ID:
7eeb00aa62b395698a28bf033e56b7c5
igserver-7.27471 13:27:04 INFO Parameters: {action=show,
id=1, controller=people}
igserver-7.27471 13:27:04 INFO Rendering template within layouts/
application
igserver-7.27471 13:27:04 INFO Rendering people/show
igserver-7.27471 13:27:04 INFO Adding Cache-Control header
igserver-7.27471 13:27:04 INFO Completed in 164ms (View: 116, DB:
21) | 200 OK [http://localhost/people/1]
Note that the hostname process ID is added to the beginning of each
line of a multi-line log statement. So even if you call logger.error()
with a string that has newlines in it, the host process ID will be
added to each line, not only the first.
This is so that you can filter your log with a regular expression
like /^igserver-7\.27471/ and not miss lines.
Improved warn() and error() methods
The warn() and error() methods now allow an Exception object to be
given as an optional second parameter. If the exception is given, then
the stack trace will be automatically logged.
For example:
begin
# do something that raises an exception
rescue Exception = e
log.error Oops, e
end
The above code will log “Oops”, and then log the stack trace.
___Why?___
Adding severity:
All lines printed to the log have a “severity” level, this can be
“DEBUG”, “WARN”, “ERROR”, etc. Normally this isn’t included in the log
output, so it’s impossible to search a log file for warnings or
errors, or filter based on severity, and it’s just a useful thing to
see.
Adding hostname and process ID
Normally, when not in development mode, a Rails app consists of more
than one Rails process responding to requests at the same time. Those
processes may be printing lines to the log at the same time, and it’s
hard to know which process printed a certain line.
Also, it’s common to have multiple servers working in parallel, and a
user’s session might involve requests to multiple servers. If the log
files are combined it’s useful to know which process on which server
printed a given line.
This makes it possible to filter a Rails log to show output from one
process only, and to combine the log files from multiple servers.
The hostname is truncated (by default to 10 characters but this is
configurable). The end of the hostname is printed, rather than the
beginning, because often the end of the hostname is more unique.

Considering there is a bit of wizardry that needs to be done and

hashes instead, but I am not quite sure I understand how to do it.
Do you have any idea?
What that comment is saying is that you can replace an array eg
[a,b,c] with a hash eg {1 = a, 2= b, 3=c}
Generating those keys is up to your client side code, approaches
included using a number you increment or going for some unique thing
you generate on the spot (eg time in milliseconds concatenated with a
random number) so that you don't have to keep track of how many fields
and what not you have created clientside.

[Rails] Re: a client and a contractor are both users, share some attrib but not others, how to implement as users
Contnuing your theme of each column being its own table - there is some sort of merit in thinking that way - at least initially. has ittle to do with rails of course, but just as a general framework of thought. If you think conceptually about things that are hard to to in relational databases and things that are easy to do. It is, for example, much harder to add a new column than a new row to an exisiting database. So, if you have a very abstracted design like this.. Entity (entity id, entity name) Rowdata (rowdataid, domainid,entityid, colname,colvalue) Domain (domainid, domain_data_type) Then you could simply add new rows into the domain table and new rows into the Rowdata table every time you want to extend the schema. This of course is far too simplistic an approach - I have mixed the schema up with the values, so it is hopelessly unnormalized), but it sort of sets the mind off onto asking the questions about when we need ultimate flexibility vs when something just needs to work simply and quickly. The answers are never as simple as you think! However, I would also say, don't dwell on the what might possible ne... but implement what is most reasonable. Of course it is judgement, but when developing we always have to use our judgement. When we have made a design decision about such a thorny issue, document it so you don't have to revisit the reasons. You may have to revisit the decision, so it would be handy to know why the decision was made the way it was.

But your spelling them out certainly relieved me a little. Having been thinking of these (potential) problems, it compelled me to think whether there's a kind of tutorial I can read up on some rules of thumb of deciding if table or no table and so on. I thought, a few days, ago, that in the worst case, if I made each column its own table, a Phone Model, a Gender Model, an Areacode Model, etc, basically every thing would have its own model, though unrealistically complex, it'd work ( sort of conveying that the more orthogonal bases you have, the better; in Linear Algebra). So building up a network of tables each holding exactly one column, I was thinking that, some empirical/theory-based rules for combining these hypothetical single column tables. And your Socratic method (I hope I am using this phrase right) isn't bad, at all. I will discuss with my supervisor for possible scenarios that call for minor/major table alterations, then I will begin to ask these questions myself :) Thanks again! Thank you, everyone!

This will not be RAILS specific thinking, but bringing experience from enterprise class systems where we have things like this all the time. You can generalize the thinking questioning when the structures are even deeper. Which attributes are common between Clients/Contractors? - If there are a lot of attributes in common you might get away with a single table, and a type field in the table. Are there relationships identified that both Clients and Contractors can have? - If for example you had a security tag table and it needed to have the associated person, and it doesn't matter if the person is a client or a contractor, then it might be worth managing that relationship via a separate table (a Person table). Do you expect to add new kinds of things? - Are Clients and Contractors the only types of Persons? Will you need to add something else in the future - e.g. Overseas Contractor which is like a Contractor but has a bunch more fields, its own processes, screens, etc. If so you may want to break into multiple tables. Do you expect to have a role concept that cuts across Clients/ Contractors? - Similar to relationships above, but let's imagine you also have roles like administrator, user, ... If those roles are independent of the Client/Contractor status, then again you might want separate tables. Do you have to worry about

[Rails] Revision: Background image contained in stylesheet
I realized that I should have included a bit more information in my
previous post, so here's the revision.
application.html.erb is correctly finding the stylesheet for my project
via %= stylesheet_link_tag 'style1' %. My webpages reflect the
styling properly with a few exceptions .. the most notable being some
.jpg images defined for background do not display at all. I have those
images in public/images.
The following is the stylesheet code containing the reference to the
image.
#navigation {
width: 180px;
height: 484px;
background: #7da5a8 url(nav-bg.jpg) no-repeat;
}
I tried the absolute path to the image above per: background: #7da5a8
url(C:\InstantRails\rails_apps\getdowninthevalley\public\images\nav-bg.jpg)
no-repeat; but that didn't work either
This worked fine until I retrofitted the webpages into the Rails

[Rails] Re: gem install mysql checking for mysql_query() in -lmysqlclie
I've had this issue before - I'm pretty sure I ended up solving it by
installing the mysql-devel package first.

[Rails] Re: Revision: Background image contained in stylesheet

rails-mailing-l...@andreas-s.net wrote:
I realized that I should have included a bit more information in my
previous post, so here's the revision.
application.html.erb is correctly finding the stylesheet for my project
via %= stylesheet_link_tag 'style1' %. My webpages reflect the
styling properly with a few exceptions .. the most notable being some
.jpg images defined for background do not display at all. I have those
images in public/images.
The following is the stylesheet code containing the reference to the
image.
#navigation {
width: 180px;
height: 484px;
background: #7da5a8 url(nav-bg.jpg) no-repeat;
}
Your path needs to specify the full relative path.
url(/images/nav-bg.jpg)
Looks like you're missing 'images/'
I tried the absolute path to the image above per: background: #7da5a8
url(C:\InstantRails\rails_apps\getdowninthevalley\public\images\nav-bg.jpg)
no-repeat; but that didn't work either
This worked fine until I retrofitted the webpages into the Rails
framework (which I really like, but which I'm relative new to).
If anyone knows the solution, I would really appreciate it ... thanks in

Thanks Fred.
Considering there is a bit of wizardry that needs to be done and
that Rails doesn't include helpers to do this simply, does it mean it
is not recommended to build such complex forms?
I am not very experienced with Rails, but I love the fact it is very
clean and I feel a bit cautious having to generate keys manually.
There is the nested forms stuff in rails 2.3 (unfortunately not yet
documented in the guide).

But it doesn't seem to work. I read

that only one level of “arrayness” is allowed and that I should use
hashes instead, but I am not quite sure I understand how to do it.
Do you have any idea?
What that comment is saying is that you can replace an array eg
[a,b,c] with a hash eg {1 = a, 2= b, 3=c}
Generating those keys is up to your client side code, approaches
included using a number you increment or going for some unique thing
you generate on the spot (eg time in milliseconds concatenated with a
random number) so that you don't have to keep track of how many fields
and what not you have created clientside.

[Rails] hpricot bug?
I get an error in the hpricot-gem on Windows XP sp3. I have tested
different versions of it and combined them with different versions of
sequel (including the latest of both).
The error triggers on the line when I do: require ’hpricot’.
The line that causes the error in the hpricot-gem in the file
elements.rb (line 395) looks like this:
nth = proc { |num,i| self.position == num.to_i }
What is proc for kind of function? Maybe the gem or component that
defines proc is out of sync with hpricot ?
NOTE: I have the same code and gem versions running on debian linux
working fine, and it also worked nicely before on windows.
I run ruby 1.8.6 and installed it with the one-click installer for
Windows.
Best regards!

[Rails] Generating a css file from ruby code
Hi all! I'm playing around with an app at the moment in which users can specify their own style settings for the majority of the HTML on their profile through selecting some form options. Alternatively they can upload a stylesheet of thier own if they have CSS experience. I thought of a couple of different way of doing this but the most logical way seemed to be creating a seperate stylesheet for each user in the model and calling this stylesheet when the page is rendered. I've created a plugin which takes a ruby hash and creates a hunk of text which is then written to a css file. http://github.com/GavinM/css_writer/tree/master I'm just curious as to whether anyone can think of a better way of doing this?

[Rails] Re: Controlling concurrency
@Fred: The information that only n more products exist will come from (@product.order_limit - @product.orders.count) = n. It's a bit more complicated than that, because I plan to have optional per- ProductVariant limits too, but let's leave it there for now. @Fred @Hassan: I don't really want to have unsold ProductVariants hanging around in the database, because the availability of ProductVariants is largely procedural. If the order_limit on the Product as a whole was 20, the order_limit on ProductVariant A was 10, and ProductVariant B had no order_limit, then I'd end up with a whole lot of questions as to how many unsold ProductVariants to create of each type, and which ones to destroy when others were sold. Bah, too much mess! @Charles: I like the idea of an OrderTaker global queue, but global queue means worker process, and worker process means extra messy infrastructure, right? I'm all for it, I'm just wondering if anyone has a better mousetrap. @Fred: Row-level locks are out of the question, since I'm not interested in blocking updates to a given row, but the creation of rows that don't yet exist in the Orders table.

[Rails] Associations, named_scope, and active records
Hello all, We are converting our application so that user-generated content such as votes, photos, users, comments, etc are all disabled instead of deleted. This serves us better as administrators of the site as well as fits into a UI redesign coming later that will include undo functionality. The question I have is would it be better to place the active=true condition part of all my associations I already have in place (little work), or do I strip my associations down to barebones and build named_scopes for my active state, and any other states? The problem here is I would need to append nearly all calls to photo.votes, photo.comments, project.photos, project.votes, etc with .active (much more work). Which is the better method in the long run?

[Rails] Re: Associations, named_scope, and active records
Makes sense just to add conditions to the associations so: class Photo has_many :votes, :conditions = ['active = ? ', true] end I presume this is what you're planning on doing at the moment? Less work and I doubt the scope would perform noticeably better (if at all) ? Why not try both methods and check the speed of each query?

I tried just using % form_tag :action = 'update' % do, along with

[Rails] Rails and Sphinx
Hi, i'm currently using ferret+acts_as_ferret for doing some searches
in the db (not so big for now, just 40k~ records, but they will be
near 2M+ soon). For now ferret it's working quite well, but sometimes
i've indexes corrupted (i use it's drb server in production) and i've
to rebuild all the indexes, so i've bad indexes, angry users and time
spent to make it right.
I'm looking at sphinx and it seems the answers to this problems, as it
seems that it doesn't have this such of problems. But i've seen that
i've to remake indexes everytime (/hour or less).. does it take a lot
to rebuild them?
Is there anyone who use shpinx in production?
Another big question about it is if it's possible to create custom
indexes without having the records in the db, for example with ferret
it's just a :fields = {:my_custom_field = {}} and then a method
named my_custom_field which set what i need (for example a list of
strings/integers, that i need to index, like category ids 4 8 15 16
23 42, and then doing a query searching with for example 15, or stuff
like that (actually i've 8 fields, but soon they will be around 12-15)
Is it possible something like this with sphinx?
For ferret there is acts_as_ferret, for sphinx what do you suggest ?
acts_as_sphinx or is there something else?
thank you

Look into the 'delta' options. That way you have a main index and a
delta index of recent changes. Quicker to update and then nightly you
can rebuild the whole thing.
Is there anyone who use shpinx in production?
I have in the past yes, using the thinking sphinx plugin.
Worked great.

[Rails] Silence logging altogether for certain actions?
Hi, I am looking for a way to silence logging altogether for certain
actions. Our app talks to other servers and session components, and
our logs get filled up with this nonsense, even in Production mode. I
want to completely silence all the automatic logging by Rails of the
basic request parts: method, params, etc.
I've seen logger.silence, but that doesn't appear to get rid of the
basic request chatter. Any ideas?

[Rails] :has_many best practice search order
I have a model_one that :has_many model_two-s, I would like to find the ten model_one's that have the most model_two's. What is the best way to do this? Model_One.find(:all, :limit = 10, :include = :model_two, :order =themost of model_two desc) or inorder for me to do this effeciently (I have thousands of model_two-s) would i need to add a column to model_one, to keep track of the number of model_two-s that model_one owns. Or is there some index i can use? What is the best practice in this situation? -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: Rails 2.3
Binh Ly wrote: Hello, I've been looking on the Internet for how to use libxml within Rails. What I'm seeing is a little confusing. If you install the libxml gem, will Rails automatically use that because its installed or do you have to explicitly set libxml to be the default after you've installed it? This posting http://www.coffeepowered.net/2009/03/16/things-to-do-when-upgrading-to-rails-23/ Says to set this in the environment file. 1. ActiveSupport::XmlMini.backend = 'LibXML' But when I do that my app crashes. Anyone have any experience with this? If you could provide the entire backtrace, it would be much easier to diagnose.

[Rails] Re: Passenger caching in development mode, wtf?
Ok i resolved it, after hours of trying to figure it out, i noticed that the cause is having config.threadsafe! enabled in development mode. For some reason it causes caching to get enabled. This option should be documented better.

Model_One.find(:all, :limit = 10, :joins = :model_two, :order = count(model_twos.model_one_id) desc, :group = model_ones.id) I could do it in raw SQL, but I don't know the exact match. Fred Cheung or someone will correct me if I got it wrong! The :joins is so you don't eager-load the models and interfere with the group concept, I suspect. The group is so you are allowed to count within each group. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: Spreadsheet -avoid reading and writing from file how?
Sijo Kg wrote:
Hi
I am using http://spreadsheet.rubyforge.org/ in my application..Usage
like
book = Spreadsheet::Workbook.new
book.write #{RAILS_ROOT}/public/uploads/excel-file.xls
render :file = #{RAILS_ROOT}/public/uploads/excel-file.xls
headers['Content-Type'] = application/vnd.ms-excel
headers['Content-Disposition'] = attachment; filename=excel-file.xls
headers['Cache-Control'] = ''
In the above i am writing to a file in a location and then read.
My question is is there any method so that writing to a file can be
avoided ..Because if there are some 100 requests the file will be
overwritten(Am I right?) or if give seperate names for the files the
upload folder will grow..So is there alternative and i can read the same
content directly
I didn't test this code, but looking at the api it looks like
Workbook#write will take an IO stream.
require 'stringio'
require 'spreadsheet'
book = Spreadsheet::Workbook.new
blob = StringIO.new()
book.write blob
send_data blob
Be sure to checkout the link below on send_data, it will allow you to
transfer the stream of data without writing it to disk first.

[Rails] How to aggregate tags on child nodes?
Let's say I have a Recipe model, and it is a parent of the Review model. Reviews are entered by users of the system, with one or more tags using the acts_as_taggable_on_steroids plugin (for instance). What I'm interested in is how to show *all* tags for a particular Recipe - meaning all tags applied to every child Review of that Recipe. For an example of what I'm talking about, look at this page from this fine website: http://97bottles.com/breweries/us/ca/santa-rosa/russian-river-brewing-company/blind-pig-ipa/ They are showing the most popular tags from all Reviews on a particular Beer. I'm trying to figure out how to do that. But I have no idea where to start, since the tagging is such a wily concept to me.

[Rails] Re: ActiveRecord Comparison Bug?
Hi Fred, Thank you for the response! What you said made sense. thanks for the explanation. However, looking at the last criteria of the == implementation, we can see why something like what i mentioned would fail: let's say i have an 2 AR objects: old = Something.find(1) = #Something id: 1 then i create a new object: new = Something.new = #Something id: nil new.id = 1 # something like this is possible, how or why is another story... new = #Something id: 1 now do: new == old = true old == new = false == method should be commutative, right? You've got something screwy somewhere... old = Toy.fin old = Toy.find(1) = #BabyToy id: 1, .. new = Toy.new = #Toy id: nil, new.id = 1 = 1 old == new = false new == old = false Rails 2.3.2.1 -philip appreciate any comments! -Moo On Apr 10, 10:52 am, Frederick Cheung frederick.che...@gmail.com wrote: On Apr 10, 5:50 pm, Moo janec...@gmail.com wrote: Anyone has any thoughts on this please? Basically the rationale is that == should mean 'do these objects correspond to the same database row ?' The reason why unsaved records are special cased is that two unsaved record would have equal id (nil in both cases) but if you saved them you would end up with 2 distinct rows in your database. I'm not sure why you're getting new ==old not being the same as old == new.
