Yes you can.
Don't touch the new method. For those cases you have to override de do_new
method
def do_new
@record = Foo.new
apply_constraints_to_record(@record)
[:baz, :lol, :omg].each do |desc|
@foo.bars.build(:desc => desc)
end
if nested?
create_association_with_parent(@record)
register_constraints_with_action_columns(nested.constrained_fields)
end
@record
end
something like that. Check lib/active_scaffold/actions/create.rb for more
options.
For the form, you don't need to do anything, just add :bars to create
columns and AS would do the job for you.
config.create.actions.add :bars
There are options for that also.
for 2) you can use an "action_link"
and 3) didn't get it. sorry :(
enjoy,
