I''m fairly new to Ruby & Rails and I come from a stricly M$ background. I''m trying to move into the world of open source, but I don''t have a good roadmap. I''m starting to develop a Rails-based product and I want to have the option to distribute it to non-hosted customers. So I''ve said all that to say this... I want to learn how to setup linux and

Does anyone know of a good resource on doing MLS (Multiple Listing Service) integration with Rails? My searches don''t seem to be turning up much information and I need to get a quick handle on what''s involved in this process. Many thanks!

is it possible to store a field of type file_column in the session? Rails crashes on me every time i try to do something like the following: @session[:newpost] = @params[:post] however if i assign each field of @params[:post[ except for @params[:post]["image"] i have no problems. Is there something that should be done to allow the file in the session? thanks adam

For documentation we use a system that generates Rd files from special comments in the code. (inlinedocs). It is crucial to be able to get the defining source code for objects like methods to extract the comments from it. Here is an R session that shows how this works for several kinds of methods and (at the end of the session) how if fails for methods of "initialize" >

Hello All, I''m trying to capture the exception message that my server application is providing in response to my Ajax.Request. However, I''m confused as to when onFailure is fired vs. onException. The onException handler has access to the javascript exception object and I''d understood that it was only called when the dispatch fails. Not sure what exactly that means

Heyo! I am setting up a self-referencial habtm relationship with the users of my app. I am using Chad Fowler''s "Rails Recipes" to get me started, and everything works great with the join table "people_friends". I add friends by doing somebody.friends << somebodyelse. However, with my app, there is an approval process so my join table has columns person_id,

Hi, I''m trying to call a remote function when a combobox option is selected, passing as an argument the current value of the combobox (paramenter "panel_id": <select id="server_interface_jack_switch_panel"

Dear all, Assume that I have an S4 class "MyClass" with a slot "myname", which is initialized to: myname="" in method("initialize"): myclass <- new("MyClass", myname="") Assume that class "MyClass" has a method "mymethod": "mymethod.MyClass" <- function(object, myname=character(0), ...) {

Dear All, In R 3.6.3 (and earlier), method dispatch used to work for methods stored in local environments that are attached to the search path. For example: myfun <- function(y) { out <- list(y=y) class(out) <- "myclass" return(out) } print.myclass <- function(x, ...) print(formatC(x$y, format="f", digits=5)) myfun(1:4) # prints: [1]

Hello everyone, I'm working on a package using S4 classes and methods and I ran into the following "problem" when I tried to create an "apply" method for objects of one of my new classes. I've found a way around the problem but I wonder if I did not paint myself into the corner. I'd like your opinion about that. So I have an object "myObj" of class

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,

Dears, I have a question about copying reference objects using the initialize method. 1) If the latter has no arguments, there is no problem to copy an object. myClass = setRefClass("myClass", fields = list(value = "numeric") ) myClass$methods(initialize = function(...){ ? value <<- 1 ? callSuper(...) }) newObject = myClass$new() newObject$value = 2 copyObject =

I am writing a function to work with class I am defining. I have a question about using nargs() inside of parentheses function. nargs() shows the same for supplying 1 argument, or no arguments at all. Here is a small example: > "[.myclass"<-function(x,...) print(nargs()-1) > x<-c(1,2,3) > class(x)<-"myclass" > x[] [1] 1 > x[1] [1] 1 > x[1,2] [1] 2

Dear all, Currently, a ts object behaves like an array, and it would be very useful to have a similar object, which would behave like a data.frame, i.e. it could be indexed, named, etc. like a data.frame. What would be the most efficient way to construct such an object? I have tried to make one on my own following the directions of class design from "S Programming" (2000) as a

Dear all, Since my package is based on S4 classes, I would like to know how to add a slot to an existing S4 class without breaking the code of users of my package. Assume the following S4 class: setClass("MyClass", representation(name = "character", type = "character", data = "data.frame" ), prototype(name =

How can I define a static member of a class? not a static method, rather a static field that would be accessed by all instances of the class.

Hello, I'd like to 'do work' on data members upon construction (i.e. without implementing it in a get method). Is this the best way to create data member 'z' upon construction? I'm thinking if .z=paste(x,y) below gets more complex I'll run into issues. setConstructorS3("MyClass", function(x=NA,y=NA,...) { this <- extend(Object(), "MyClass",

I'm wrapping a function in R and I want to record all the arguments passed to it, including default values and missing values. I want to be able to snoop on function calls in sourced scripts as part of a unit testing framework. I can capture the values fine, but I'm having trouble evaluating them as if `force()` had been applied to each of them. Here is a minimal example: f0 <-

Hi, I''m pretty new to all related to bdd and rspec and I have the following question. Is it possible to stub actions that return different objects depending on the parameteres they were called with? Something like this: MyClass.stub!(:method).with(1).and_return(@mock_object_1) MyClass.stub!(:method).with(2).and_return(@mock_object_2) I know I could use
