I've been using the 3.1.2 gem from github.
Looking at line 73/74 of lib/active_scaffold/attibute_params.rb via the
github code browser, I don't see anything different from what is in my
gem. So while I can see about pulling the latest commit, I doubt it's
going to clarify anything.

Final update... once I looked at the associations in Fief again it
dawned on me that the ones I was tripping over are incomplete
specifications and confuse AS because it can't find the other end.
Correct specification for the four associations are:
has_many :lent_forces, :class_name => "LentForce", :foreign_key =>
"sourceFief_id", :inverse_of => :lending_fief
has_many :borrowed_forces, :class_name => "LentForce", :foreign_key
=> "holderFief_id", :inverse_of => :lessee_fief
has_many :prisoners, :class_name => "Prisoner", :foreign_key =>
"sourceFief_id", :inverse_of => :owning_fief
has_many :held_prisoners, :class_name => "Prisoner", :foreign_key =>
"holderFief_id", :inverse_of => :holding_fief
and then creating a World works.
So, bottom line is that I'd like to see the error message in this case
be a bit more useful - I spent a day on a wild goose chase based on
what the error said instead of the 30 minutes that it took once I got
on the right track.
However, looking at the code that raises this error, it's not obvious
to me how to make the statement more descriptive...

An update on this topic. After chasing down the inflection rathole
for most of yesterday, I pulled back out and went back to simple A/B
testing of Fief. It turns out that the error message is rather
misleading (and I guess you can count this as a "grump") as the
problem is not the association between World and Fief as is reported,
but the issue is between Fief and a pair of classes that each have a
pair of foreign keys back to the Fief table.
What I'm bumping against is the following definitions in Fief:
has_many :lent_forces, :inverse_of => :lending_fief
# has_many :borrowed_forces, :inverse_of => :lessee_fief
has_many :prisoners, :inverse_of => :owning_fief
# has_many :held_prisoners, :inverse_of => :holding_fief
the first two "has many" declarations match up with the following
lines in LentForces:
belongs_to :lending_fief, :foreign_key =>
"sourceFief_id", :class_name => "Fief"
belongs_to :lessee_fief, :foreign_key =>
"holderFief_id", :class_name => "Fief"
while the second two match up with the following lines from Prisoner:
belongs_to :owning_fief, :foreign_key =>
"sourceFief_id", :class_name => "Fief"
belongs_to :holding_fief, :foreign_key =>
"holderFief_id", :class_name => "Fief"
With the lines from Fief shown commented above, I can add a new World
via AS. If I uncomment either of them, then I trip the error. So,
there is a problem, but it's not where it's reported.
More as I chase this down...

Are you using rails 3.1? Can you check with last commit if error message is
better now?
