How do I get ''save'' to execute without commit? I have tried: ActiveRecord::Base.connection.begin_db_transaction # do some stuff that doesn''t issue a database COMMIT statement # then: @myObject.save # this issues a COMMIT but it shouldn''t! Shouldn''t it wait until I''ve called: ActiveRecord::Base.connection.commit_db_transaction ? what am

Hi all, I'm seeking feedback (good, bad or indifferent) in regards to developing (further) a new class system for R, that uses encapsulated class definitions (i.e. the method definitions are literally inside the body of the class definition). A working (however very rough and poorly tested) system is available in my R package "oosp" with documentation in the vignette

I need a single boolean which would be "globally" accessible to all instances of a class. Seems like the boolean should be in the class prototype, but I was troubled by the difficulty of setting the prototype boolean to true. Maybe I''m missing something? var MyObject = Class.create(); MyObject.prototype = { bSwitch: false, ... other methods and properties } var oMyOb1

Dear R users! Several languages like C# or VB allow one to create properties; typically these are under 'get', 'set' tags. My question is this really, what are similar or comparable strategies in R, and what might be preferred? I have a couple of situations where I want a certain computation to belong to a class, but I do not really want to seperate it out to a stand-alone

Hello Everyone: As usual, thanks in advance for any help. I was hoping to get some more advice on this question: I'm trying to write a subsetting routine for an S3 object I've created -- lets call it myObject. myObject has a few attributes basically of type string and numerics. Its atomic value is just a vector of ints. I want to write my own subsetting routine to subset myObject in

Dear all, i generated several GLM objects, named myobject1 to myobject25. Now i'd like to update both of them. So i tried: for(ii in 1:25) { assign(paste("myobject.updated", ii, sep=""), update( myobject[ii] ,.~ + VAR2)) } Doesn't work I also tried to get all the names in a vector and update(names.myobject[ii],.~ + VAR2) Stiil doesn't work Any ideas

Hey everyone, I''m trying to create an object that will have some properties predefined, but will allow me to pass in properties to override those standard props if needed. I''m trying something like: var myObject = Class.create(); myObject.prototype = { initialize: function(element, options) { this.element = $(element); this.name = this.element.id; this.options =

Hey Cats, I''m having a problem. I''m working with an object that contains a bunch of arrays: var myObject = { "data": [ {"line": [1,"aoo","far"]}, {"line": [2,"boo","ear"]}, {"line": [3,"coo","dar"]}, {"line":

I was writing my blob at http://railsblob.blogspot.com/ which is for new people who are new to Rubby and I was learning if Mongril or Lighthttttp? or Web Rick is better for me. Have you any advice. Thanks? Rails Blobber -- Posted via http://www.ruby-forum.com/.

I''m trying to debug an a uncaught exception: Permission denied to get property Object.constructor error. I have some code like this: myObject.js ------------ function myObject (arg1, arg2, arg3) { //does some constructor related stuff } myObject.prototype.createSomething = function() { // do more boring stuff // return an Array; } manager.js ----------- var fakeHashMap = new

I am working on a new package to do fire department analysis. I am working with emergency dispatch data from different agencies that all contain the same information but have slightly different formats. Typically the variable names and date-time formats are different. I am getting pretty good at reading in and rearranging the data so that it is essentially in the same format, but it is common

Dear all How can I obtain the name of the argument passed in a function? Here is a simplistic example of what I would like to obtain: myfunction= function(name) { print(paste("The parameter name was",unknownFunction(name)) } myfunction(myobject) [1] "The parameter name was myobject" Thanks Francisco

Dear listers, I am working since a while with the sp package and still wonder how the plot methods are managed with sp spatial objects. For instance, SpatialPolygonsDataFrame objects have obviously a plot method. However it cannot be found in the list provided by methods(plot) . Furthermore ?plot.SpatialPolygonsDataFrame, nor ?plot.SpatialPolygons, etc.. provide a help, though the lattice

Hi all ! I noticed a strange behaviour of the function `class<-` when a class-specific '[[.' method is defined. Here below a reproducible example : #-------------------------------------------------------------------. counttt <- 0 `[[.MYCLASS` = function(x, ...) { counttt <<- counttt + 1 # browser() x = NextMethod() return(x) } df <- as.data.frame(matrix(1:20,

I need to create a sort of transaction around some Active Record objects that perform many insert/updates. Example: class MyObject def transaction &block @my_var = value self.instance_eval block end end MyObject.new.transaction do Model.create Model.collection.create etc...... end I have a gem that add a method into AR::Base and I need to read

Hi R-listers, I am trying to better undertand what we would call "functional paradigm" use of S/R to better map my programming activities in other languages. This little function is aimed to create an object (at the end end, it would have it's own class): -- myObject =function(){ list( a=1, foo=function(b) { cat("b:",b)

I created some scaffolding for an Address model and an Addresses controller. When running the functional tests for the addresses controller, I get this exception: "NameError: uninitialized constant Addres" The exception seems to start from this function: def list @address_pages, @addresses = paginate :address, :per_page => 10 end I''m guessing pluralization bug?

I have a few forms that I''d like users to fill out. The results of the form will be sent to a few addresses. What''s the least painless way to do this and keep everything DRY? There''s no database involved. Ideally, I''d like to email the form questions with the answers inline. Seems like using ActionMailer and separate email views would be overkill in this

Ok, so now Users need to be associated with Organizations. I''ve created a migration and added a ''organization_id'' column to the users table. I want the default organization_id to be the first Organization. So I have :default => Organization.find(:first). But it''s complaining about not being able to find the constant ''Organization''. Any
