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.

I have a decoupled form embedded in my pages ? a search box that has date fields ? and of course the search fields are not in my model. However, picking dates is a great use for the Dynarch calendar. It seems that by using the syntax: <%= render :partial => ?filter_box? %> In my view and... <%= dynarch_date_select ''filter_box'', ''begin_date'' %>

Hello. I have a program that accesses a metadata (translation) table for column names as well as the ordering of columns for a specific model. Also in there is a collection of bool options such as column_visible_on_form, column_visible_on_screen_quicklist etc. The idea is that our customer can specify to a certain extent how their layout/user interface will appear.

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.

I have the acts_as_ferret plugin installed. Everything searches great, but I would like to limit the results (i.e. by ''end_date'') and sort them (by ''end_date'').

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. =====

Hi! I have a table with visits with a visited_at: attribute which is a datetime field. They seem to be stored as UTC. Now I want to count all visits each day and return something like: { 2013-01-01: 8, 2013-01-02: 4, 2013-01-07: 9, ... } So, I did it like this which kind of works...: def self.total_grouped_by_day(start_date, end_date) visits = where(visited_at:

Hi, I am new to Ruby and Rails, so I don''t know if this is my fault, but maybe this is a bug in Rails (I''m using Rails 3.0 beta) which should be reported.

I have the code for computing a weekly event: (start_date..end_date).select{|d| d.wday == wday} but I am wondering if anyone has any ideas for using this to figure out a recurring event for every other week.
