I want to make a for loop that concats strings onto a variable: html .= var1 + "this is a test" + whatever What is the syntax that does this in ruby/rails? Also, is there a ''print'' method in ruby? Because when I try to use render_text it will only let me use this once. -- Posted via http://www.ruby-forum.com/.

After digging through the rails code to figure out why my asset_host wasn''t getting applied to emails, I realized that it''s because the config object in the context of a mailer is config.action_mailer and not config.action_controller. This means you need to set asset host separately for emails, as config.action_mailer.asset_host. Should this be considered a bug? Is it really

I am new to R and really like to get a handle of basics in short period of time. What I am trying to do is get myself a list of must-do's (read in data, batch execution, delimiters, basic modeling commands) in R as in Stata or SAS. I am just wondering how to execute a R batch file in RGui. Suppose I have a script file (like do file in stata, or sas file in SAS) under c:\whatever.R, how can I

Hi, I'll need to buy a new wireless card. I need a recommendation for PCMCIA wireless card that simply works with CentOS out of the box. By "works out of the box", I mean that it doesn't need ndis wrapper (or whatever it is called), kernel hacks, or whatever. Thanks

Hi, I upgraded (in place upgrade, preserving my dovecot configs) to a newer release of ubuntu in order to gain access to slightly newer Dovecot release and be able to use Dsync for migration from Cyrus, here is my doveconf -n output: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-44-generic x86_64 Ubuntu 12.10 auth_debug = yes auth_default_realm = whatever.com auth_master_user_separator

simple question: how do I output something from within <% %> tags? e.g. like ''echo'' in PHP. I thought it would be ''puts'' or ''print'' but neither seems to work. right now I always close the %> and open a <%= which is tedious. -- Posted via http://www.ruby-forum.com/.

Dear R-users, I have some questions about the scope of functions, which I would like to illustrate with the following example: ### First example require(Hmisc) combine.levels <- function(x,y) browser() whatever <- function(x,y) combine.levels(x,y) x <- 1:5 names(x) <- LETTERS[x] y <- 6: 10 names(y) <- LETTERS[y-2] combine(x,y) # no debugging break whatever(x,y) # debugging

For example, rather than dividing by "x" you can divide

Greetings, When using a 'foreign' function (from another package, say function 'whatever' from package 'foo'), you can of course just require the package and then just have whatever(...) in your code. However, I would like to use the foo::whatever(...) form instead, just for documentation purposes (easier to see what function comes from what package). Is there a

Hello, Just a single problem i can''t solve. The scenario... I have a controller called "places" but i don''t want to link the users to /places/whatever, i want something like /no/whatever. How to achieve this? I have in my routes.rb: map.resources :no, :controller => "places", map.connect '':controller/:action/:id'' map.connect

I did a yum update last night at about 23h15 EDT (-4). No upgrade. I just did a yum update this morning at about 08h45 (-4). for my system there's about 348 megs of updates. Now all I have to do is figure out how to remove OO.o 2.0.whatever which is being upgraded to 2.3.whatever. I'm using 2.4.1 on my 4.6 boxes (have always been using the latest OO.o on them since installation a

I have two issues, potentially related, potentially not. First off, a bit about my environment: I am experiencing the same issues on two boxes, one of which is running red hat linux ES 4 update 6 i386, the other running red hat enterprise linux server release 5.1 x86_64 . Both appear to be running samba 3.0.25b, both are members of an active directory domain . There are 7 domain controllers in

Let''s start with this: class whatever ( $myType=''other'' ) { file { "some-config-file": ... content => $myType ? { ''this'' => template("whatever/this.erb"), ''that'' => template("whatever/that.erb"), ''other'' =>

It was recently pointed out by Wacek Kusnierczyk that although one is prevented from doing FALSE <- TRUE one *can* do assign("FALSE",TRUE) and have an object named ``FALSE'' with value TRUE in one's workspace. This apparently has no deleterious effects; e.g. doing sample(1:7,replace=FALSE) gives a random permutation of 1:7 as expected and desired. I.e. the local

I'm trying to figure out how I can get a generalized 2D list/array/matrix/whatever working. Seems I can't figure out how to make the variables the right type. I always seem to get some sort of error... out of bounds, wrong type, wrong dim, etc. Very confused... :) x[["some label", "some other index"]] <- 3 x[["some other label", "something

In an effort to encapsulate my dependence on class in order to deal with oldclass/class in Splus I defined the functions tfclass <- class "tfclass<-" <- function(x, value){ class(x) <- value ; x } and also the function classed <- function(x, cls) {class(x) <- cls; x} This last allows me to end a function definition with ... classed(somecalc,

Hi, It appears to me that the command: ruby script/generate scaffold whatever money_field:decimal(10,2) will not generate a valid migration. Therefore it appears to me only two ways to achieve the desired result is: 1.1 Omit the the precision/scale on the scaffold command 1.2 Edit the migration file by following the "do |t| ... end" with the command: change_column :whatever

I need to know what controller and action the user is currently in to do various things in my layouts/application.rhtml file. Isn''t there is a better way than: <% if params[:controller] == "whatever" && params[:action] == "whatever" %>some html<% end %> I know in the controllers you can just use controller_name, but that is not provided

A sysadmin moved a share from one Windows server to another. I am now getting error 13 when trying to mount the share from the new server. The following worked before the server was replaced: mount.cifs //ipaddress1/share1$ /mnt/share1 -o credientials/home/whatever/.smbcredentials,rw mount.cifs //ipaddress2/share2$ /mnt/share2 -o credientials/home/whatever/.smbcredentials,ro Change: server

Hi A simple question again, but I can't find it by google-ing R-help. Quite simply, I want to read in the contents of a number of files, using read.table, and assign the results to elements of a vector/array/list/whatever. I want it so that, if my vector/array/whatever is "pos", that pos[1] will give me the first data frame, pos[2] will give me the second etc... Kind of basic
