These company names obviously can have an ''&'' in the name of the company (example Barnes & Nobel). The auto complete works beautifully. However, the problem arises when I pass the name of the company to the

R-Community, (System Details at end) I recently downloaded R 1.7.0 win95 binaries from http://cran.us.r-project.org .

Hello, Today I noticed that the number_to_currency helper didn''t work anymore (it just returned the numeric value, without any currency). I tracked down the error and saw that editing line 89 ( number_to_currency method) as follows solved the problem : Old piece of code : begin format.gsub(/%n/, number_with_precision(number, :precision => precision, :delimiter =>

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?

Hello All, I am having an issue with AAF and sorting results of a search. Right now, I have results being split onto pages of 10. The results are being sorted alphabetically, but not across multiple pages - it''s just sorting the 10 it pulls down on each page.

Anyone have a quick solution on how to format a number in a text_field tag? <% text_field "price", "amount" %> returns 100.0 and it would be nice if it showed 100.00 Of course, number_with_precision works nicely, but how do you make that work with text_field? I thought maybe overriding the getter in the model. However, this means I would have to bring the helper
