create table events (
id int not null auto_increment,
name varchar(100),
city_id int not null,
primary key (id)
);
class Event < ActiveRecord::Base
belongs_to :city
end
<tr>
<td><label for="event_city">City:</label></td>
<td><%= select("event","city",City.find_all)
%></td>
</tr>
<select id="event_city" name="event[city]">
<option value="2">New York</option>
<option value="1">Boston</option></select>
When I submit the form I get following exception "City expected, got
String".
Do I need to convert the city_id to Integer in controller?
Thanks.

I''m trying to do something similar to this. Basically I have a
:belongs_to
relationship, and I use collection_select( or simply select( to display
these on the form:
<p><label for="goal_project">Area |
Project</label><br/>
<%= select(''goal'', :project_id,
Project.projects_for_select, { :prompt =>
"pick your project"}) %></p>
If I use :project_id most things work: validations do the expected, the
object is saved as expected. However, when a validation fails, the item is
*not* wrapped in the fieldWithErrors div.
If I use :project, validations work. The item *is* wrapped in the
fieldWithErrors div. However, I get the "Project expected, got String"
error.
I guess I can load the appropriate Project object in the create action, but
I suspect there is something simple that I am overlooking.
Thank you.

Perhaps Rails should provide an option to automatically copy errors of association attributes to their foreign key attributes. It may be better to validate project_id itself, using either "validate" or "validates_each" to check the nil-ness and integrity of the project attribute. -- We develop, watch us RoR, in numbers too big to ignore.
