For instance say I want to find all of the people in a given location. class Location < AR:Base has_many :people end class Person < AR:Base belongs_to :location end My SQL tables look like: CREATE TABLE

i have a need to create a ''virtual'' attribute. Is the following possible? class User < ActiveRecord::Base # user things are owned by user at his selected location has_many :owned_things, :class_name => "Thing", :conditions => ''user_id = #{id} and location_id = #{location_id}'' attr_accessor :location_id end class AccountController <

Pretty much a newbie here, looking for help on select boxes in forms.... Is there any way in the view to sort the options of a drop-down select box? My current code (within a larger _form.rhtml file) is: <div class="form-element"> <label for="asset_location_id">Location</label> <%= select ''asset'', ''location_id'',

Is it supposed to do that? I find it very confusing.

I''m new to Rails3, and I''m just trying to get one last thing to work before I call it a night. The situation is the following (please if the code is horrible, just let me know, still learning): I want to log a dive. I might have a new location on that dive at which point I have to create a new Location, and then create the dive. A dive has_one location. A location has_many

I''m having trouble with a validation that depends on an attribute of a belongs_to parent. If the child is added to an unsaved parent (parent.children << new child), the has_many collection parent.children includes the unsaved child. However the belongs_to attribute child.parent appears to be nil until the parent has been saved. Without access to the parent attributes, the validation

I like the simple search of ferret; I would like to take this one step further and do an advanced search; the user will type in key words and use a drop down box to select the location; now how to pass this location_id to the ferret search so it searches key words only on matching records with same location_id? thanks -- Posted via http://www.ruby-forum.com/.
