Exclude holidays in a subset of dates?
Hi All,
I am iterating through dated materials, with variable start and end dates,
and would like to skip procedures everytime I encounter a weekend or
holiday. To do this, I thought the easiest way would be to create a
TRUE/FALSE vector corresponding to each day where it is TRUE if a workday,
and FALSE if a weekend or holiday.
So far I have been able to do this for weekdays:

Associated child records not created on creation of a parent.
I am trying to create a record with association. Within the create
method, I would also like to pre-populate dependent (has_many) records
from a template in the database.
The child records are <u>mysteriously rolled back </u> if I insert
them in a loop. If I try to insert a single child record, it works.I
have read the books and tried to google my way out of this but am at a

how to delete a parent record and child records?
Wow, got myself lost as *soon* as I left the hand-holding exercises in
the books.
I''m trying to set it up so when I click the (scaffold-generated)
''destroy'' link on one (of a list) of parent MySQL records, the children
records in a different table get deleted also.
Very simple setup: my tables are ''customers'' and ''accounts''

Referencing a table''s fields.
Hello,
I recently set up a rails application, and wanted to provide helper methods in my model class.
I was confused that the class DOESN''T refer to its fields as instance variables. I merely had to
type in the field names to be able to work with their data.
Here''s an example:
I have a "Chessgame" class with a begindate and an enddate. To get the number of hours

LDAP problem
Hello Brian,
Sorry to my late answer, I did what you suggest previously
This error suggests a problem with your certificate. If it used to work
previously, then check it hasn't expired.
openssl s_client -connect devsamba.lucas.ufes.br:636
copy-paste the certificate into a pem file, including begin/end lines
openssl x509 -in mycert.pem -noout -enddate
And check your root CA

problem with chron scales in lattice
I can't get the scales parameter in xyplot of lattice to work as I
expected. I'm using R-2.1.0 and lattice 0.11-8. There should be year
labels from 1992 to 2004 for the x axis in the plot below, but instead
only a few of them appear, and in the wrong spots, as if the coordinate
system has changed after finishing with the panel function.

Array of dates/times from time.now till nextweek
Hi,
I would like to make @dates in my controller.
I tried the following:
startdate = Time.now
enddate = startdate.next_week
for enddate > startdate
@dates << startdate
startdate = startdate.tomorrow
end
But I get an errormessage when I check the syntax:
"warning: useless use of a variable in void context"
Anyone?
Thanks!
Steven.
