RubyMine inspection doesn't see model fields and flags hundreds of warnings Follow

Howdy,

Using RubyMine 7, but this problem has happened since I started using RubyMine (back at RubyMine 3).

In short, I get dozens to hundreds of inspection warnings in my code because of missing fields/columns in my models.  Thing is, the fields do exist and the code works fine.  But RubyMine can't "see" the valid fields.

So  two initial questions:

1) How does RubyMine know what fields a model has?  Does it read the annotation headers or does it instantiate a model instance to reflect the know fields?

2) How do I let RubyMine know what fields my model has?  Ideally in some automated way so I'm not manually maintaining a field list.

I did notice in RubyMine 7 a few things:

a) Some (not all) simple string fields in a model are found and the inspection doesn't complain about them.
b) Fields that are other data types including numeric/BigDecimal and integer are almost always flagged as unknown (that could be a red herring, but I really don't know)
c) Sometimes boolean fields are flagged as unknown as well, but sometimes they are not
d) RubyMine 7 has the plus os updating the warning to include the model it's looking at.  Sometimes, it shows the correct model and sometimes it shows a parent model

As an example.  This is an excerpt from a model, truncated for clarity:

----- models/finance/po_tran.rb

# == Schema Information
#
# Table name: f_po_trans
#
#  id                  :integer          not null, primary key
#  fiscal_year_id      :integer          not null
#  po_group_id         :integer          not null
#  po_num              :string(255)      not null
#  po_num_raw          :integer

# ... other fields

class Finance::PoTran < ::AuditedRecord
  include Finance::Utilities
  include Finance::BudgetCheck

  has_paper_trail
--------------

Inspection doesn't complain about the 'po_num' field (a string), but it does complain about the po_num_raw field?

We are using strong parameters, so while there are validates refs for some fields, there are no attr_accesible or other such methods in the models anymore.

It's driving me a bit crazy because I really want to see the green 'all-ok' indicator for my code, but right now, nothing I write will ever be problem free because of this.
