Hi! Is there rails version of "where column in (value1, value2, ...)"? I know i could do OR many times, but this way is shorter. I''m ruby/rails newbie, so i have a problem with converting the hash, which i''m receving from the search form into the string for :conditions in find method.

Railoholic-Anonymous Members: I am tooling around with the idea of forming a project which would create a calendar plugin/engine with the following features: 1. DB schema mapping all necessary iCal (RFC-2445) fields. 2. Probably utilizing either vpim (vpim.rubyforge.net), or iCalendar (icalendar.rubyforge.net).

It''s not a real web service, more like a REST-style thing where I''ll just be tweaking a servlet running on another machine and sending it some data. Does Rails give me anything to work with for doing that? I read the web service stuff but it''s overkill for what I need. I

I''ve installed acts_as_authenticated and have that working like a charm and now would like to add the acl_system2 plugin so I can do some role based authorization stuff.

Don''t know if anyone else has experienced this but I''m having a problem with the access_denied method in Ezra''s ACL access control plugin.
