similar to: BigDecimal column type?

I was just playing around in irb and noticed that while BigDecimal + Integer => BigDecimal, BigDecimal + Float => Float. Is there any reason for this? It seems inconsistent and means you have to check the class of any number you add to a BigDecimal, which looks very un-Ruby-like to me. Ashley

Hi everyone, I''m new to Rails and Ruby, and have been working my way through the Pickaxe and Agile Rails books for the last week or so. With a background in payroll apps I found that the default ActiveRecord mapping of decimal columns to float variables really bothered me! Financial calcs need high levels of accuracy and floats just don''t give you that. I know there are a bunch

I need to do some precise math, going to 12-14 decimal places, so I''m using BigDecimal. How can I store this in a db? I''m using postgresql 8.1.0, if that matters at all. I found a plugin [1] but it gives me the error "You have a nil object when you didn''t expect it! The error occurred while evaluating nil.each_pair," with no line number. The plugin itself

Hi I''ve just tracked down a wierd error that AFAICT is caused by an error not being raised in the setup: context "An Asset" do setup do @provider = Provider.create(:name => "Provider1") @product = Product.new(:name => "Product1", :provider => @provider) @applicant = Applicant.new(:first_name =>

So, I''m personally cool with this change (patch from #5454, applied in [4596]), and I''ll make it work for Oracle tomorrow. But just wondering if folks considered the performance impact of the change? From a simple test it seems that BigDecimal math is about twice as slow as using Floats.

Hi I can''t get heckle working. In fact, I''ve built an example so simple that it either shows a bug, or I am being really, REALLY stupid. Heckle does not appear to support RSpec directly, so I''m trying to use spec --heckle (RSpec trunk as of 10 mins ago, Heckle 1.4.1). I''ve constructed this pair of sample files: 18> ~/Desktop/heckle_test % cat

Hi, I have a mysql schema with some decimal(20,20) fields. Now, I made a rake db_schema_dump for deployment of my applications on other machines. Rails created a schema.rb with the decimal fields as float. After a rake db_schema_import the fields are just float not decimal. How can I force rails to create decimal(20,20) columns instead of float? Thx. Marc -- Posted via

hi there, I am about to embark on a mission critical financial web application, and was wondering weather ruby on rails is the best fit for this type of project. More specifically I am worried about floating point errors. Would it be more appropriate to use a more statically typed framework (.NET)? thankyou. -- Posted via http://www.ruby-forum.com/.

Is there a method that converts BigDecimal 1520.0 to "one thousand five hundred and twenty"? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I have a strange problem with my setup of Passenger and Ruby Enterprise Edition. Sometimes the loading of BigDecimals from the database and session fails (silently) and the variable containing the BigDecimal is just empty. I cannot pinpoint where/when/how it happens, and it IS only periodic. I am using the newest versions of both Passenger and REE - I have even tried to run with latest commit

Hi In light of the fact that RSpec mocks are going into maintenance mode in the near future, I was wondering what everyone was switching to. I liked the look of FlexMock most, so gave that a shot. However, there''s a few things that don''t work well with RSpec due to the traditional differences in the way Test::Unit cases are written vs RSpec specs. (One spec per

Hi Just trying to spec a Rails model that defaults a valid_until date to this time tomorrow. I''ve done something similar involving Dates, and you can stub the :today method to return something fixed. But when I tried this with Time, I found that RSpec calls Time.now four times per spec. So there''s no way to spec code like 1.days.from_now . The best I can come up

<http://www.apress.com/book/bookDisplay.html?bID=10368> Came across this as a stub page browsing Amazon UK. This is good news! I''m surprised it hasn''t been discussed on the list before. Was Chad keeping it a secret? I hope it will have plenty of BDD theory. I''m still waiting for that magic book I can give to someone and say "here - read this, it

Bleeding-edge story-writers, How are you structuring your specs? I am working on a new project and tried this: ./lib ./blah ./spec ./blah ./stories But it breaks autotest, so I moved stories parallel to lib and spec. Also what about suffixes? I have adopted "xyz_story_spec.rb", and "xyz.story" for the time being, with the line runner =

Hi Easy one - I just wondered why all spec files for rspec_on_rails end "_spec.rb" instead of just ".rb"? They are all inside the spec folder so surely the fact they are specs is implicit? Ashley

Hi all, I''m working on a financial app, and have set up some columns in my tables as decimals with precision => 8 and scale => 2. My migration looks like: change_column :lineitems, :price, :decimal, :precision => 8, :scale => 2 change_column :payments, :amount, :decimal, :precision => 8, :scale => 2 I''ve run the migration and restarted the server. I

Hi Not sure if this is the place to ask this or not. I''ve upgraded to RSpec 1.0.5, installed the latest TextMate bundle, but whenever I do "Run Behaviour Descriptions in selected files/directories" I get this: /Users/ashleymoran/Library/Application Support/TextMate/Pristine Copy/ Bundles/RSpec.tmbundle/Support/lib/spec_mate.rb:18:in `run_files'': private method

Hi Something that''s gnawing at me... to avoid using the SQLite3 gem I''m stubbing it out like this: before(:each) do @database = mock("SQLite3 database") SQLite3 = Module.new SQLite3::Database = Class.new SQLite3::Database.stub!(:new).and_return(@database) end But then it keeps nagging me:

I''ve noticed that I phrase a lot of shared behaviours in plural, eg describe "All payment_details views" How about a "they" alias to "it" so you can write describe "All payment_details views", :shared => true do they "should have a card number field" do # ... end end WDYT? Ashley
