Hello, an S4 class "Foo" is defined with a setter, $. For several reasons, the setter calls a function, .foo.update(). However, bypassing the argument names of the setter does not work. Question 1: Why not and how can I fix this? Question 2: What is the way to define either the function or the setter to modify the original object (not returning the modified copy of it an overwrite the

Hi, I am having trouble using before_create when I have an specialized setter method: before_save :set_campaign_start #----------------------------------------------------------------------- ------- def set_campaign_start self.campaign_start = Time.now end # We want the date to always start at midnight

Hello! I have noticed that mapply() drops names in R 2.3.1 as well as in r-devel. Here is a simple example: l <- list(a=1, b=2) k <- list(1) mapply(FUN="+", l, k) [1] 2 3 mapply(FUN="+", l, k, SIMPLIFY=FALSE) [[1]] [1] 2 [[2]] [1] 3 Help page does not indicate that this should happen. Argument USE.NAMES does not have any effect here as it used only in a bit special

Rails extends Ruby with mattr_accessor (Module accessor). As Ruby''s attr_accessor generates getter/setter methods for instances, mattr_accessor provide getter/setter methods at the module level. In below example, you see that mattr_accessor declared in the class context of LookupContext. It''s declared in class, not module. However, modules are defined in LookupContext, for

In my project I have a group of foreign types (C++ classes) that I want to use, but don't want to represent as structs within LLVM. For example, for each field in each C++ class I have a setter and getter function that I'd like to use. The setters and getters are "extern C" functions to avoid problems with C++'s name mangling. After going over the documentation it

Hi, I can''t find how do i created a getter and setter property for a non db property. what i have done isnt working, i have a cnt mass assign error. Here is what i''ve done: attr_accessor :creator_is_participant def creator_is_participant @participe end def creator_is_participant=(participe) if participe == true @participe = true else @participe

There are datatypes that need to be converted back and forth from a string representation: they need to be parsed both coming from the database, and coming from elsewhere like views. Dates are an example, and I recently needed to implement a more forgiving converter for decimal numbers. So we have here at least two flows of execution, for example: post.date = "22-jan-2007"

Im developing a User model for my application (newbie stuff, but I have to start somewhere). I followed the tutorial at http://sonjayatandon.com/05-2006/how-to-build-a-secured-web-application-with-ruby-on-rails/ and decided to add an email field. The problem is that the email is not being saved on the database and I end up with two email variables: @email and email. validates_presence_of

I have a field called Fax in my model. I store it as a 10-digit number with no other characters but I display it as a nicely formatted phone number. I have a validation on it like this: validates_format_of :Fax, :message => ''number should be formatted using (XXX) XXX-XXXX'', :with => /^\(\d{3}\)\ ?\d{3}-\d{4}$/ If I put 1234567890 (10 digits) in my field, the

Greetings, I am trying to understand how to making a subset assignment function. Take the example where of making a "last" generic function. last <- function(x,...) UseMethod("last"); last.numeric <- function(x, ...) x[length(x)] last.list <- function(x, ...) x[[length(x)]] ..... Now we run into the problem at hand if we want to assign something to the last

All, I''m having a hell of a time figuring out what is going on here. I''m trying to override one of my getters so that I can format it a certain way in my form. But I can''t seem to get text_field to call the appropriate method on my object. So here''s my getter: public def FAX fax = read_attribute(:FAX) puts fax

(This message was originally written on StackOverflow -- the formatting is much prettier there -- http://stackoverflow.com/questions/1283046/problem-with-setter-override-on-activerecord) This is not exactly a question, it''s rather a report on how I solved an issue with write_attribute when the attribute is an object, on Rails'' Active Record. I hope this can be useful to others

I have some properties that I want setable externally, but readable only internally. I''ve played around with attr_writer (and attr_reader separately) but can''t figure out how to get either to work. I can do what I want using attr_accessor, or just straight out defining the prop setter method. Anybody know how to use attr_writer or attr_reader with a model? You da man, Joe

In the Ruby bindings, set_X and get_X are renamed to remove the get/set, so MSet::get_matches_estimated() becomes a read-only property (if I have my terminology right) of the Ruby MSet class called matches_estimated. This matches how a Ruby programmer would expect a class to be designed. I was looking through the getters and setters list. I wonder if a few entries shouldn't be there, (the

Hey.. So I have a model that has a lot of number fields. Each of these go through a process when read in and read out to add/remove commas (between every three numbers) to make them more readable. The getter I currently have is like this: def sale_price Listing.insert_commas(read_attribte (:sale_price)) end and the setter is: def sale_price=(price) write_attribute(:saleprice,
