I'm looking into building a group work app for my final year project next year. One of the core parts is organising group meetings. I plan to make this as powerful as possible and adding a map can help get rid of excuses such as "I didn't know where it was".
I have been unable to find any simple solutions to embed maps into my Rails app...
I'm trying to pull data from Jim Breen's WWWJDIC. The raw data returned has a lot of information delimited in several different formats.
The data pulled in the example below is from here:

I've been experimenting with BCrypt, and found the following. If it matters, I'm running ruby 1.9.2dev (2010-04-30 trunk 27557) [i686-linux]
require 'bcrypt' # bcrypt-ruby gem, version 2.1.2
@long_string_1 = 'f287ed6548e91475d06688b481ae8612fa060b2d402fdde8f79b7d0181d6a27d8feede46b833ecd9633b10824259ebac13b077efb7c24563fce0000670834215...
k = [1,2,3,4,5]
for n in k
puts n
if n == 2
k.delete(n)
end
end
puts k.join(",")
# Result:
# 1
# 2
# 4
# 5
# [1,3,4,5]
# Desired:
# 1
# 2
# 3
# 4
# 5
# [1,3,4,5]
This same effect happens with the other array iterator, k.each:
k = [1,2,3,4,5]
k.each do |n|
puts n
if n == 2
k.delete(n)
end
end
puts k.join(",")

I have a Rails 2.3.5 application and Im trying to render several Partials from within a Model (i know, i know -- im not supposed to). The reason im doing this is im integrating a Comet server (APE) into my Rails app and need to push updates out based on the Model's events (ex. after_create).
I have tried doing this:

I don't understand class_eval in ruby.
class Module
def attr_ (*syms)
syms.each do |sym|
class_eval %{def #{sym}= (val)
@#{sym} end} = val
end
end
end
What does the % mean?
What does class_eval do?
And where is (val) coming from?
Thanks

I have a method that returns an array of arrays.
For convenience I use collect on a collection to gather them together.
arr = collection.collect {|item| item.get_array_of_arrays}
Now I would like to have a single array that contains all the arrays.
Of course I can loop over the array and use the + operator to do that.
newarr = [] ...

in php you just embed php with html in a .php file.
how do you do it with ruby (note: i dont want to use frameworks for that, just pure ruby + html to learn how it works).
thanks

I Have an engine in vendor/plugins. My problem is, that i seemingly can´t extend the engine-model with a model in the base application.

In Ruby, I'm trying to extract from text a string that starts with "who" and ends with the first of either a ")" or "when" (but doesn't include the ")" or the "when").
I've tried the following:
who.*(?=when\b|\))
which fails the case where it finds both a "when" and a ")".
Any ideas?
Many thanks

Is there a way to fetch the model and the translations in one query when using globalize2?
For example, having a model called Language which have two fields, code and name of which the second is translatable I do the following:
en = Language.find_by_code("en")
and it runs this query:
SELECT SQL_NO_CACHE * FROM `languages` WHERE (`l...
