Hi Kenny,
That is exactly what happens. I have no clue how to solve this. I
assume that I am not the only person to use ActiveScaffold that way.
Therefore, I guess it is just something I haven't configured or
misconfigured.
I searched the documentation again and re-read the example with that
before_create_save method (on the embedded scaffold page).
I tried to implement it in my controller like this:
class InstanceController < ApplicationController
before_filter :load_course
# This is needed to prevent an exception when the sub-form doesn't
validate
protect_from_forgery :only => [:create, :update, :delete]
active_scaffold :instance do |config|
config.actions.exclude :show, :search
config.create.label = "Add a new date for this course"
config.create.link.label = "Add a date"
# Columns to display in the sub-table
config.columns = [:course_start, :course_end]
end
def load_course
begin
@parentcourse = Course.find(active_scaffold_session_storage
[:constraints][:course_id])
rescue
@parentcourse = Course.new
end
end
def before_create_save(record)
record.course_id = @parentcourse.id if @parentcourse.id
end
end
But that didn't change anything.
Maybe the solution is here http://code.google.com/p/habtm-with-deferred-save
but frankly speaking, I am not keen to install it and further tweak my
application with a potentially unstable patch.
Of course, I could just use AS for all my controllers but then my
customised views would be useless.
Could it just be that AS can't do what I want to do?
Thanks for your advices.
Christian.
