delete_all not resetting auto incement in database
...art off at 840 (responding to the number of skills
times the number of times I reloaded data).

FROM... and not TRUNCATE (which resets the auto increment counter)
It seems that Skill.delete_all doesn''t reset the auto_increment
counter on the database table.
Hope you can help me with my questions here:
Q1: Is it a bug in Rails that Class.delete_all does not reset
auto_incement counter?
Q2: Is there a workaround that I can use?
(for instance, how can I do an SQL query ''TRUNCATE skills'')...

How can I find out which attribute is screwing up pluralize/singularize?

end in _code instead of _id, etc.
I have the model working great in the console, where I can create any
modeled object and reference other objects without issues.
However, I''m running into problems with plugins...

HABTM tables). I am a big perfectionist and I frequently run "SHOW
COLUMNS IN table;", so I naturally expect to see the "id" column the
first one listed. However,

Heeelp - no idea what''s going wrong.
...Listing.new(params[:listing])
@listing.categories = Category.find(params[:category_ids] # this
works
@listing.subcategories = Subcategory.find(params[:subcategory_ids] #
doesn''t
if @listing.save
...
...
end
And the databases:
create table listings (
id int not null auto_increment,
<various text fields>
primary key (id)
);
create table subcategories (
id int not null auto_increment
name varchar(100) not null,
category_id int not null,
constraint fk_items_category foreign key (category_id) references
categories(id),
primary key (id)
);
crea...
