So, I have a User has_many :profiles. The most recently dated profile is considered the current one. I need to sort these users by name, but the name attribute is a member of the associated table.

I have a text field that I use for logging in users. Due to the design of my site, I don''t have room to put the word "username" in front of the text field so I''d like to actually display it inside the field and then have the word clear when the user clicks on it.

I have a simple method in a model, to send out e-mails via the script/runner. def Reminder.dropoff @messages = Reminder.find(:all, :conditions => [ "time < now()"]) @messages.each do |mes| Mailman::deliver_send_message(mes) end end However, it''s not sending e-mails. When this exact code was dropped in a controller, it worked great... is there

For a really long time, I''ve been using DBDesigner from FabForce.net. For those of your who''ve never used it, its a freeware visual entity-relationship diagram tool, which allows you to make database designs visually instead of in SQL DDL.

Hey all, I''m casually shopping around for a host that will give me a virtual server running Debian. It would host some of my rails projects and probably some svn. Does anyone know of a good host? Anecdotes about satisfaction would be nice. Thanks, Bryan -- Posted via http://www.ruby-forum.com/.

If I browse to \myRoRApp, I get the "Welcome aboard" screen. I''ve done the ruby scripts/generate controller MyTest, and "Rolling with Ruby on Rails" tells me I should be able to browse to \myRoRApp\MyTest and see an error page, but what I''m actually seeing is a fastcgi config file! I have installed fastcgi, but apache can''t "see" the

Hi, I have a question today regarding how the various form elements in _form.rhtml are named. I understand that for a database table "persons" with a column headed by "name", then in _form.rhtml it will probably be like: <p><label for="person_name">Name><br/> <%= text_field ''person'', ''name''

Does anyone know of a good package that can convert a PDF into HTML? Cross-platform compatible is a plus, but I can live with Linux-only if it comes to that. -- Posted via http://www.ruby-forum.com/.

Hi there, we made a PHP and Impakt2 based web content management system for schools with specific features that work really well for schools. The way I designed it was so there was one central set of source code and an empty (in terms of rows in tables) database structure.
