Hi Tiago,
hobo_index Document.all.map { |d| d.review_required? }
*undefined method `default_order' for #<Array:0xb38ca844>*
I think this was the same error I got during one of the iterations where
I manually filtered the output of Document.find(:all) into an array.

Hi Donald,
How about: Document.all.map { |d| d.review_required? }
It's not fast, but unless you can map the review_required logic into
SQL, this might be the way to go.
Thanks,
TF

Hi everyone!
I have a model (Document) which presents a non-table-column attribute
"review_required?". I need to be able to filter the input to
hobo_index and/or table-plus such that only the records with a true
value are displayed.
The review_required? attribute is a relatively complex function of
the children of the Document model that would be extremely tedious
and error-prone to replace with a pre-calculated table column.
What works:
hobo_index Document
and
<table-plus fields="this, review_required?" without-search-form param/>
Produces a nice list of documents
Document Review Required
doc 1 Yes
doc 3 No
doc 4 No
doc 6 Yes
etc.
So I am sure the review_required? attribute works.
What doesn't work:
I have tried numerous ways of filtering the output of Document.
Document.find(:all, :conditions=> ... ) doesn't work because
review_required is not field in the table.
Document.review_required(true) doesn't work because it doesn't
recognize the method review_required (its there).
I have tried many variations on this theme, including adding a second
method review_required without the ?, but all fail for the same reason.
Document.apply_scopes(:review_required => true) same failure, can't
find review_required. Grasping at straws here.
I used the output of Document.find(:all) to create an array of the
records that meet the criterion, but hobo_index fails because the
array is not a finder.
Help anyone! :-[
