Boa tarde pessoal. Estou utilizando o intant rails com ruby v.1.8.6 e rails 2.0.2 com um servidor sqlserver2000, minha base de dados usa o collation SQL_latin1_general_CP1_CI_AS, quando tragos strings com acentuação e cedilha não consigo visualizar os carateres corretos, sei que para exibir corretamente o texto no ruby tenho que usar UTF-8.

I'm installing R on an Irix 6.5 machine and R fails to understand dates prior to 1 Jan 1970. This first cropped up early in the test scripts (Examples/base-Ex.R): > > seq(as.Date("1910/1/1"), as.Date("1999/1/1"), "years") > Error in fromchar(x) : character string is not in a standard unambiguous format The root there is the

Hi all, I''m looking for a function, gem, etc. that will help to unify dates as they come in different formats. If the date comes in (1/2/2012,2012-01-02,01-02-2012,20120102,01022012, etc.) it would be nice to have it come out 2012-01-02. I''ve searched for a few days and only find ways to convert this format to that format. I might be using the wrong search terms and this

I wonder why ruby core method ''take_while'' does not work as expected in the below Rails console example: irb(main):003:0> arr = [] => [] irb(main):004:0> arr << Date.today - 15.days => [Sun, 27 Jan 2013] irb(main):005:0> arr << Date.today - 25.days => [Sun, 27 Jan 2013, Thu, 17 Jan 2013] irb(main):006:0> arr << Date.today => [Sun, 27

I''m using the date_select form helper for a date_of_birth field on an ActiveRecord object. When I try to save a date earlier than 1 Jan 1970, ActionController punts with ActiveRecord::MultiparameterAssignmentErrors. The message it gives is "1 error(s) on assignment of multiparameter attributes". I was able to catch the exception and look at it, and it is certainly complaining

Hello, we are receiving some data, sample below - with a weird time/date stamp format, we need some help with R on converting this time date stamp to a useable field in R, date and time in a data-frame. The developer says its the number of milliseconds since midnight, January 1, 1970. sample: *1232558018624* --------------------- How do I interpret the time stamp? Is there a date, i need

I''m seeing a behavior in Rails that I find very strange. Having worked quite a bit with Oracle with other languages I would always dutifully do ALTER SESSION SET NLS_DATE_FORMAT = <my_date_format> and ensure I use that date format in my application. With Rails I still have not figured out how to execute an ALTER SESSION statement after connecting to the database (I''m using

I can't seem to get a histogram of dates: tmt910% R --vanilla R version 2.13.0 (2011-04-13) Copyright (C) 2011 The R Foundation for Statistical Computing ISBN 3-900051-07-0 ... > temp <- as.Date(1:200, origin="1970/01/01") > range(temp) [1] "1970-01-02" "1970-07-20" > hist(temp) Error in .Internal(inherits(x, what, which)) : 'x' is missing

Hi Can anyone explain why a date becomes numeric when you loop over a series of dates? > dt <- Sys.Date() > dt [1] "2017-11-14" > class(dt) [1] "Date" > dts <- dt - 1:0 > class(dts) [1] "Date" > > for (i in dts) { + print(i) + print(class(i)) + print(as.Date(i, "1970-01-01")) + print(class(as.Date(i,

x <- as.Date(Inf, origin = "1970-01-01") x #> [1] NA str(x) #> Date[1:1], format: NA unclass(x) #> [1] Inf It's not clear what the correct behaviour is. The documentation for ?Date has: "It is intended that the date should be an integer,", which suggests that -Inf and Inf are not valid dates. But if that's true the behaviour for max.Date() needs some

I am trying to generate a line graph with quarterly time buckets (with nice labels) on the x-axis. The first block of code below will generate the graph with nicely formatted x-axis labels, but the "type=" and "col=" options are not recognized when factors are used for the x-axis. The second block, where the quarter values are mapped into dates, will plot the line nicely but

Hi, I''m having a problem with dates (laugh if you must :). $ rails --version Rails 2.3.5 $ ruby --version ruby 1.8.7 (2010-01-10 patchlevel 249) [x86_64-linux] I have a bunch of data in a text file that I''d like to place in my DB but am ending up with odd results when I save the data.

Hi All, I want to know the EOL date for the below gems for ROR.

Hello, I would like to have the y axis show dates in a 3D 'persp' plot. The following example works... x <- spot y <- as.numeric(dates) # class(dates) produces output [1] "Date" z <- t(price) persp(x, y, z, ticktype="detailed") ...however the y axes contains 'meaningless' integers (days since 1970-01-01 is not very intuitive!) Changing the

FIXED: Transaction is a reserved word, and it cannot be used even though I put it into its own module. So my guess is Transactions::Transaction still somehow got resolved to the Rails internal Transaction class. Renamed the Transaction (and its subclasses) to Transact and it works fine now.
