BigDecimal column type?
I was hoping 1.1 would provide a way to map SQL "decimal" column types to BigDecimal values, since BigDecimal is part of the Ruby standard api as of 1.8. But I don''t see any support for that in the migration documentation, and when I try to let Active Record do the mapping for me, it seems to coerce the column into a Float (as the AwdwR book says). Is it really there in

Storing BigDecimal in the db
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

Float -> BigDecimal
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.

Mapping to BigDecimals instead of Floats
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

super global dummy method for gettext + rails 2.2
Hi, since rails 2.2 doesn''t work with gettext anymore I decided to use a gettext dummy method until the gettext team relases a working version for rails 2.2.

So I need a method called _ which is available in alle models,

Ruby EE: Problem with BigDecimal
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

params vs @params
Is there a difference in the way that params[] and @params[] are handled? Is the ''handling'' done by Ruby or Rails? A pointer to the relevant documentation would be sincerely appreciated. Or just an answer would be ok too ;-) Thanks, Bill -------------- next part -------------- An HTML attachment was scrubbed... URL:

ruby suitable for financial apps?
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/.
