Hello, I am attempting to create several plots based on "site" (~300 total) and am having trouble with the code. I simply want to create a plot using the code, plot(year, peak), for the following dataset. I would like for each site to be plotted on a separate page and the plots saved in a directory. Would a "foreach" loop work? I tried a "by" statement, but

Hello, I installed Emu48 (emulator of HP48 and HP49 calculators) on Wine, but unfortunately it misbehaves. The "screen" of the emulated calculator shows strange colors (sometimes yellow on white, sometimes a pale pink color, depends on selected "skin"). Any suggestions to fix the problem? This is wine 1.1.2 on Arch Linux. Thanks! -- Renan Birck ~ Santa Maria, RS, Brasil

I have a Project that has_many Tasks. Tasks belongs to a Project. When I try the following: project = Project.new project.tasks.build I get: >> s = Project.new => #<Project:0x25f9e28 @attributes={"name"=>"", "end_at"=>nil, "updated_at"=>nil, "published_at"=>nil, "user_id"=>nil,

I am using R for a graduate class on linear models that I teach. I sent the class a sample transcript of explicit construction of the model matrix and use of the QR decomposition. One of the members of the class picked up on the fact that the model matrix was not what I advertised that it should be when a two-sided formula is used. A one-sided formula works properly. For example, >

When you define belongs_to in a model, you can either access association or association_id. I was wondering how Rails would handle things if you set each one to be different. I made two simple models: class Foo < ActiveRecord::Base; end class Bar < ActiveRecord::Base belongs_to :foo end Now here''s a script/console session. >> f = Foo.create => #<Foo:0x270ec10

I''m trying to set up a directional self-referential HABTM to represent an arbitrary semi-hierarchical structure; it works for any data prepopulated into the db, but when I try to create a new relationship, I just get NULLs in both key columns (or 0''s if I turn on the no-null constraint). Here are the migrations: class CreateNodes < ActiveRecord::Migration def self.up

Hi all I want users to register on my page. To register, they only have to deliver an email and a password. Then a link with an activation token will be sent to them, and after clicking the link the user sees a page where he should fill in further details, means: a username. My model looks like this: class Member < ActiveRecord::Base validates_presence_of :username, :if =>

I have a helper that uses some jQuery code that I would like to move out of the helper method. I am trying to move it to application.js but it will probably end up in a different file. I have two reasons for wanting to do this. 1) I want to keep all my jQuery code seperate to my HTML code 2) I want to change the append to an appendTo so I can add a highlight effect, appendTo which is proving

Hello List, I''m trying to generate examples for some list-helpers I have coded which use in my projects. Basically, the Playlist class uses one anonymous module in has_many that acts as helper between acts_as_list and my desired API: class Playlist < ActiveRecord::Base # associations go here has_many :playlist_items, :order => :position, :dependent => :destroy has_many

So I want to SELECT from multiple tables, so as to be able to do "SELECT FROM foo, bar WHERE foo.id=bar.id AND bar.baz=23". How do I do it with AR#find? Also, I need this for associations. has_many et. al. have :finder_sql, which is nice, but feels like a Pyrrhic: it''s basically doing the association in pure SQL, defeating the purpose of AR. -- -Alder

Hi, When and why are nameless functions generated in LLVM IR? Also, for the clarity, is it possible for a nameless function to have external linkage? (I think not, but I would like to get it confirmed anyway) -- Anitha

I am running Win2K (RTM build 2195) and ever since RC2 I have had problems copying files from my Win2K machine to my RedHat 6.1 Linux (stock kernel 2.2.12-20) box. The Linux box is running Samba 2.0.6. I either get: J:\mail\archive\todo\dingo>copy dmail-122499 \\alder\mikenel Access is denied. Or I get a file with a funny character created on the box: [...] -rwxr--r-- 1 mikenel mikenel

I have two objects, QuoteInput and Insured. QuoteInput has one Insured and Insured belongs to QuoteInput. I don''t understand what I''m seeing. I assign an Insured to a QuoteInput. The Insured object has invalid data. I call save! on the quote input. QuoteInput has no validations. I expect two things to happen - 1) an exception should be thrown, indicating that there was a

File.open in core Ruby is nifty, in that it automagically closes the file when you''re done using/manipulating it. I''m wondering whether there''s something like that for ActiveRecord? So you can do: AR.find(23).open {|ar| ar.foo = ''bar'' ... } And ar.save would be called when the block closes. -- -Alder

Hi all, I''m seeing some unexpected behaviour in a nested model and I''m not sure if it''s a bug or if I''m doing something wrong. When assigning nested attributes, the associated object gets replaced with a new record. Example code: class Car < ActiveRecord::Base belongs_to :driver end class Car < ActiveRecord::Base belongs_to :driver end
