very basic newbie question!
Bringing up (trying!) my first rails app... no OO experience
the scaffold generator automatically creates new activerecord objects
for the create/edit form using:
def new
@schoolclass = Schoolclass.new
end
I wanted to initialize the object, so I added to the object creation
statement as follows:
@schoolclass = Schoolclass.new(:day=>1, :start_time=>"2006:01:01

Naming join models
I''ve been playing around with EdgeRails and checking out some of the
new features. The one that will probably have the biggest affect on
my designs is join models (or :through associations). For those not
familiar with this feature, it lets you replace your habtm
association with a pair of has_many associations indirected through
an intermediate model class.
Looks like good

Getting a time select input
I''m having trouble workign out which ActionView DateHelpers to display a
time input for an ActiveRecord field of type :time.
I just want an hours input and a minuites input. I can get these with
time_select helper using :field_name and :prefix but it gives both hours
and miniutes the same name.

Sorting by two fields
I have a list of TimeSheet objects from an ealier AR query, which I
can sort by the full name of the user like so:
@time_sheet_entries.sort! { |a,b| a.user.full_name <=> b.user.full_name }
I can sort by the started time like so:
@time_sheet_entries.sort! { |a,b| a.start_time <=> b.start_time }
My question is how do I do a sort so that the list is sorted primarily
by user.full_name

AAF Sorting by date - what am I doing wrong?
I''m trying to sort my search results by Date, in descending order. I''ve
done quite a bit of reading through the forums here, and I''ve tried two
different suggestions.
This just returns results in the same order as a search without a sort:
sort_fields = []
sort_fields <<
Ferret::Search::SortField.new("ferret_created_at",:reverse => :true)

How should I select rows from a join-model based on more than one association?
A concrete example:
We''re building a system to organize the information about workshops
being held in various conventions. A convention has more than one
workshop, and each workshop can be held in more than one convention.
Also each workshop has a host, who is specific to a workshop being
held in a specific convention.
For example, Matz may host an "Introduction to Ruby"

How about? :

I''m misunderstanding how stubs works
We''re still just starting out with Mocha/Stubba, so please forgive any
newbie errors.
I''m using "stubs" to test some realtime functions, to control exactly which
time is returned from Time.now. I would expect the following test to pass:
def test_two_stubs
t = Time.now - 60
Time.stubs(:now).returns(t)
start_time = Time.now
t += 20

Multi-parameter assignment
Hi,
I''m trying to submit data from text boxes on a form to one variable in
my controller, in the same way that datetime_select has date(1i),

I''ve named my variables event[start_date(1i)] event[start_date(2i)] and

[LLVMdev] interesting LLVM code optimization issue regarding timer registers
This problem was reported to me by a friend who has an LLVM port that is
not put back to open source.
Essentially, there is an intrinsic call _lr which is a load register.
so then user code has something like:
start_time = _lr(TIMER_REGISTER)
.....
some_code_to_time
....
end_time = _lr(TIMER_REGISTER)
So what happens is that LLVM moves the code as follows:
start_time = _lr(TIMER_REGISTER)

validates_uniqueness_of with habtm
it''s a blog...
class Entry < ActiveRecord::Base
has_and_belongs_to_many :categories
end
similarly:
class Category < ActiveRecord::Base
has_and_belongs_to_many :entries

I wish to make sure that the owner doesn''t add the same category to a
given entry more than once... I''m thinking that validates_uniqueness_of
should be usable here. But can''t

How do I deal with ActiveRecord::RecordInvalid: Validation failed:
Hello all,
I am currently writing model tests in rails 4. I am attempting to add an
error to a reservation object if the total number of reservations for a
given date and time has reached a pre-determined limit.
When my test runs, it is hitting the appropriate code but it is raising the
following error as opposed to just giving me an error in the object that I
can use.

multi-level cox ph with time-dependent covariates
Dear all,
I would like to know if it is possible to fit in R a Cox ph model with
time-dependent covariates and to account for hierarchical effects at
the same time. Additionally, I'd like also to know if it would be
possible to perform any feature selection on this model fit.
I have a data set that is composed by multiple marker measurements
(and hundreds of covariates) at different time

Adding Time when Blanks
Greetings,
My data set has dates and times that I am working with. Some of the times
in Time_of_end are blank. This is supposed to dictate that the particular
experiment lasted 48 hours. I would like to add 48 hours to the start
Start_of_Experiment for another column as End_of_Experiment including both
the ones with 48 added and those with early times. I was thinking

Active Record Question
Hi-
Say I am returning some collection of DateTime items and I only want
to compare the month. Is there a way to do this directly in the find?
Something like this...
@coll = Collection.find(:all, :conditions => ["date.month
= ?",Time.now.lat_month])
Thanks!

in cdr_csv and cdr_odbc. but here my point is on cdr_odbc. some information,
including start_time and end_time is given by cdr event but the problem is
that these two information(start_time and end_time) is not getting save in
cdr_odbc. I
