similar to: <% if ... -%> What is this?

I''m in the process of documenting templates right now, and I figured I should see what happens when you use them with arrays: $ cat ~/bin/test.pp $values = [this, is, an, array, of, values] $content = template("/tmp/templates/testing.erb") file { "/tmp/temtest": content => $content } $ cat /tmp/templates/testing.erb <% values.each do |val| %> I got

Native ERB in ruby, and eruby, seem to lack the -%> feature for suppressing trailing newlines. Thus erb -n script gives errors. Where is Rails ERB so I can invoke it directly? Thank you Hugh

Hi, Is there any performance difference between rendering partials vs. calling a helper? When we initally started coding we built a bunch of small partials and if there is a significant performance overhead with them, we''ll probably try to switch them over to helpers. They seem like they would be quite similar but I don''t know the full details of how partials are handled.

Is there an easy way to deal with nil properties in templates? All I''m aware of are these methods, and it''s quite tedious and surely violates DRY. <%= @member.name unless @member.name.nil? %> <%= @member.name.to_is %> <%= "#{@member.name}" %> csn __________________________________________________ Do You Yahoo!?

I got a new 20 inch iMac dual core today and am busy getting it all setup. A couple of issues though: 1. Is the Ruby 1.8.2 install by Apple still botched or has that been fixed? I recall someone had fixed the rbconfig.rb to get it working. Is this something I still have to do? 2. Does anyone know if Locomotive is using the uniersal binaries, or is it targetting PPC yet? I couldn''t

I''ve tried the following line in ruby script/console require ''digest/md5'' Both my Mac (Intel iMac) and my Windows box return "false"... Any ideas what could be wrong? I was trying to do the RoR Recipe on page 54 of Chad Fowler''s new (beta) book. -Mark -- Posted via http://www.ruby-forum.com/.

I''ve written a simple Rails migration that adds an index to an existing Postgres table: class AddIndexToEvents < ActiveRecord::Migration > def change > add_index :sf_events, :account_id > end > end However, when I run the migration, it fails due to a syntax error on the CREATE INDEX line. I''m expecting some SQL like this to be generated: CREATE INDEX

Hi everyone, coming from PHP something in the .rhtml files has been confusing the heck out of me. Why does this work? <% for header in @all_headers %> <%= header.subject %> <% end %> and both of these don''t work <% for header in @all_headers puts header.subject end %> --------------------------------------- <%= for header in @all_headers puts

Is it possible to get the current Controller''s action from within the Model? I have a situation where I want a piece of validation to run on edits, but not on new creates. Thanks, - Mark -- Posted via http://www.ruby-forum.com/.

The view file (eg. apps/views/items/list.rhrml) is still displayed even when the action is hidden (hide_action :list). How can I hide view file form being automatically displayed in this circumstance? thanks, jigar -- Posted via http://www.ruby-forum.com/.

Hi I am scratching my head on this not being a ruby person... I am turning my kickstart files into templates, but am having issues with percent signs in free form text. This returns a syntax error: %post OK, fine , let me escape it: %%post No error, but the end result is %%post Not quite what I wanted I''m missing something blindingly obvious - can someone point me to it? :-)

Hello, Quick question. I have written a C function - I would like to make it return two vectors to the R environment - one STRSXP vector, and one INTSXP vector. Is this possible/ easy to do using the API? I looked, but could not find the answer to this question in the "Writing R Extensions" guide. Thanks very much for your help!

Hallo phorum, i have custom rest action. routes.rb: map.resources :schools, :collection => { :graduations => :get } SchoolsController: def graduations @schools = School.graduation(true) end link somewhere in navigation: <%= link_to ''Schools with graduation'', graduations_schools_path %> All works OK for me, but Rails needs (of course) a template for controller

I''m pulling text out of a database that contains special characters, like the trademark sign. For example, a typical string might be like this: string_from_database => "Some Special Brand\231 is for sale this Thursday through Friday." The \231 is the trademark sign (TM). ERB converts this to question marks. So, my question is -- how can I get it to display the trademark

image_tag(source, options = {}) Ok, when I want to use an image I added the following code: <%= image_tag "dsf.jpg" options = {[align="right", style="padding-right: 10px; padding-top: 5px;"]} %> However, this doesn''t seem to work, it doesn''t like how I have the "options" part setup. I''m sure there is something very easy

Anyone know of a good (fast) way to encrypt/decrypt uploaded files in RoR? I''ve seen this project: http://ezcrypto.rubyforge.org/ but it only seems to encrypt strings and such. I need to encrypt files once they are uploaded, then decrypt them when they request the file back. Any ideas? Thanks, Mark -- Posted via http://www.ruby-forum.com/.

I have a Flash application that is sending JSON data to a Rails app. I want to be able to read the JSON from the controller. Does anyone know where I can go to figure this out? I''ve Google''d around but can only find instances of converting to JSON, not the other way. Example: Flash -> Sends JSON -> Rails Controller receives JSON and converts it to a class -- Posted

I have a common situation and would like best practice suggestions from some of you more experienced rails developers. In my DB I''ve normalized tables in a traditional manner, e.g. I have Posts which have authors stored in a Users table. My problem is when I go to show a list of Posts and I want to display the author name (e.g. post.author.name) ActiveRecord appears to do a SELECT

I know the scaffold generator is really only useful for beginners and/or very the preliminary state of a project, but I find that I use it a lot (especially, since I am still a beginner). There are a couple of things I find myself tweaking (or wanting to tweak, but never getting around to tweaking) each time I generate a new scaffold: 1) Change the layout from blah.html.erb to
