Hi,
So, I have run into a bit of a problem.. In my active scaffold list,
I have added some virtual attributes on my model, and have those being
displayed... Since they are not real columns in the database,
activescaffold does not allow them to be sorted by (completely
understandable).
This was a bit of a problem, but I saw the method "beginning_of_chain"
could override and potentially solve this problem... So I made a
scope in the model which performs a bit of a complex query using a
chained combination of select, join, where, and order. However, I
quickly saw that when doing this, the order_clause is not being
detected in active scaffold...
I am not quite sure why this is, because I couldn't quite understand
what the current_scoped_methods in active record is doing, and why
that is returning nil... The query does have the text in it "ORDER
BY"...
So I have a feeling something in this code needs to be adjusted:
module ActiveScaffold::DataStructures
# encapsulates the column sorting configuration for the List view
class Sorting
# ...
def set_default_sorting(model)
model_scope = model.send(:current_scoped_methods)
order_clause = model_scope.arel.order_clauses.join(",") if
model_scope
# If an ORDER BY clause is found set default sorting according
to it, else
# fallback to setting primary key ordering
if order_clause
set_sorting_from_order_clause(order_clause, model.table_name)
@default_sorting = true
else
set(model.primary_key, 'ASC') if model.column_names.include?
(model.primary_key)
end
end
....
Can anyone give me some advice on how to solve this?
