does anybody know what the hell "render :action => ''list''" means??? is "render" a method? is :action a parameter? thanks a lot. -- Posted via http://www.ruby-forum.com/.

In Depot, the demo application in the the Agile book, actions that modify the model such as add_to_cart redirect to another action that has a clear view role, like index, or show_cart, instead of generating the view themselves. This uses an HTTP redirect that goes to the client and returns. Is this an idiomatic way to design the flow in Rails? -- fxn

Hi All, Accidentally posted this in comp.lang.ruby, now trying again in hopefully the right place: I''m having a bizarre problem. I have a page that let''s you share a link from the current page with other users. You can share with other users of the site (by selecting them from your list of friends) or arbitrary users by entering e-mail addresses. In both scenarios the site

hello all. ive come to the point where im thinking about deploying my ''rails on rails'' app-development solution built in camping. mainly, im wondering what the barriers to thread-safety are. for db, i use redland, and afaik it spawns a single db connection for each find, and keeps a pool around to reuse. iow, no ActiveRecord. are class-vars a problem? theres one that

what is the cleanest way to do something for every request of a particular type (Verb, and Content-Type header)? i''m trying to figure out if shipping a custom camping.rb is avoidable, and if, how i should structure a patch my app http://whats-your.name/yard/ uses exclusively JSON based messaging between server and client. this means POST bodies are JSON, and not querystring.. camping

Hi, I have a big data frame: > mat <- matrix(rep(paste(letters, collapse=""), 5*300000), ncol=5) > dat <- as.data.frame(mat) and I need to do some computation on each row. Currently I'm doing this: > for (key in row.names(dat)) { row <- dat[key, ]; ... do some computation on row... } which could probably considered a very natural (and R'ish) way of

Hey Everybody! I was wondering if/how Camping can process more than one request at once (i.e. not what Rails does). I''m fairly new to threads, and I bought a book, and read some of it, and dived into the Camping source... I found some thread stuff but I''m not... entirely sure. So I thought I would ask!

Considering the python code: for k, v in d.items(): do_something(k); do_something_else(v) I have the following for R: for (i in c(1:length(d))) { do_something(names(d[i])); do_something_else(d[[i]]) } This does not seem seems idiomatic. What is the best way of doing the same with R? Thanks. Luis

Hello, I have a vector of 1,000,000 numbers and another vector of 1,000 divisors. What I'd like to do is to divide the first 1,000 numbers of the first vector by the first divisor, then the next 1,000 by the second divisor and so on. I came up with this, but I was wondering if there is a more idiomatic, R-like way to write it: x <- ... divs <- ... for (i in seq(from = 1, to = 1000000,

My application runs a backgrond process and after running for a while I get this error in my logs: #<Errno::EMFILE: Too many open files Lasty, the ONLY code I have that does anything with files is: File.open(image_path, "wb") do |file| file.puts file_content end Any idea what this means? -- Posted via http://www.ruby-forum.com/.

im using Mongrels to serve up /usr/portage/packages for other gentoo boxen. since i guess im the guinea pig with the DirHandler, ran into a couple issues: first, the client showed no files in the remote binhost, turns out the DirHandler was adding a trailing "/" to every filename, presumably making the client think they were directories, not files. attached is a patch which fixes this

I was wondering, imagine this situation. You have browser 1 on machine 1 and browser 2 on machine 2. I created a div so that I can update certain elements on the database. Is it possible to have the data rendered on browser 2 using ajax but without using the periodically call remote? Is it possible to use the submit event from browser 1 to trigger browser 2 to update? thanks, Bing --

Hi, I have a standard type authentication technique direct from AWDWR, so there is a before_filter :authorize_employee, :except => :login in my employees_controller.rb the authorize_employee is in application.rb def authorize_employee unless session[:employee_id] flash[:notice] = "Please log in" # save the URL the user requested so we can hop

summary: how to structure an R file such that it can be both 1. used as a script via, e.g., (from OS commandline) $ Rscript foo.r bar=baz 2. imported and called as a function via, e.g. (from R commandline) > source('./foo.r) > foo(bar='baz') ? I'm looking for the 'R equivalent' of how python supports this usecase. details: As discussed in the thread beginning

e, elemental, is a stack for the data web there are 4 components: earth, air, fire, water earth is a pure-ruby RDF triple-store, with a fs backend. no dependencies on 3rd party databases, just add filesystem (tm). theres also a ram backend built with the Mongrel URI-classifier trie as the primitive datastructure. from these two it should be easy to extrapolate how to write a memcached/hadoop

I have a shared account on Site5.com running Rails v1.0. I installed the RJS template plugin within my project. My controller function gets called, but my corresponding RJS template does not get called.

I''m trying to get Lighttpd started, and understand how it works (not quite there yet with Ror). Some questions: 1) Can I run Lighttpd as a main server instead of Apache2? 2) When hosting different RoR projetcs, will there be one server for each? Or is it one server running all? 2) Can it do everything Apache can? Like PHP, webdav, etc? -- Posted via http://www.ruby-forum.com/.

after investigating why the reloader wasnt working , i discovered 2 probs, one of which was sorta my fault (but will likely happen to others who make one-file apps) first, my app was like this: #!/usr/bn/env ruby %w{applib1 applib2 digest/md80 airbus}.each{|r| require r}} if __FILE__ == $0 Mongrel.config do handler ''/'', Camping.reloader.new(__FILE__) end end not
