Using now() to determine what should be displayed
I''m trying to create a paginated list that will take note of the "end_date" field in my table. This is what I have: @post_pages, @posts = paginate(:posts, :per_page => 10, :order_by => ''end_date'') in the controller.

Using AND in :conditions queries
I have what amounts to a simple search engine running through a table using input from a form. Everything works fine when looking for "title" or "body" But, when I want to couple that with an AND statement the search still works fine, but it seems to disregard the AND statements. Code below: In the view: <%= start_form_tag :action=> "show_search" %>

Group by clause
Hi Does acts_as_ferret support a :group clause? For e.g any rails options like :select or :group etc? or is it that it supports only few of such options?Like it supports :include Thanks -------------- next part -------------- An HTML attachment was scrubbed...

What I am stuck on is that ''1'' gets its data updated,

Foreign key confusion
I have 2 models right now: "users" and "posts". When a user creates a post I would like their id to be recorded under "user_id" in the "posts" table. Under the "user" model I have: class User < ActiveRecord::Base has_many :posts end And under the "posts" model I have: class Post < ActiveRecord::Base belongs_to :user

Activerecord equivalent of the SQL "SUM()" function.
Search doesn''t seem to be working, so forgive me if I''m covering old ground here, but I''m having a difficult time figuring out how to implement a "SUM()" function using Active record. Obviously, I could just create a query, but I''d rather make it part of my active record object. Basically I have an object called "Report <

trouble using ActiveRecord classes
I''ve been trying unsuccessfully for the better part of today to write a worker that can use by ActiveRecord model classes. The bizarre thing is that worker just stops at the point accessing the database connection. An exception isn''t raising, it just dies. My worker class is below, I''ve interspersed log messages throughout to try to determine where it is dying. =====
