Protected Instance Methods

after_update_save(record) click to toggle source

override this method if you want to do something after the save

# File lib/active_scaffold/actions/update.rb, line 132
def after_update_save(record); end
before_update_save(record) click to toggle source

override this method if you want to inject data in the record (or its associated objects) before the save

# File lib/active_scaffold/actions/update.rb, line 129
def before_update_save(record); end
do_edit() click to toggle source

A simple method to find and prepare a record for editing May be overridden to customize the record (set default values, etc.)

# File lib/active_scaffold/actions/update.rb, line 67
def do_edit
  @record = find_if_allowed(params[:id], :update)
end
do_update() click to toggle source

A complex method to update a record. The complexity comes from the support for subforms, and saving associated records. If you want to customize this algorithm, consider using the before_update_save callback

# File lib/active_scaffold/actions/update.rb, line 73
def do_update
  do_edit
  update_save
end
