do_create() click to toggle source

A somewhat complex method to actually create a new record. The complexity is from support for subforms and associated records. If you want to customize this behavior, consider using the before_create_save and after_create_save callbacks.

# File lib/active_scaffold/actions/create.rb, line 93
def do_create
  active_scaffold_config.model.db.transaction do
    @record = update_record_from_params(new_model, active_scaffold_config.create.columns, params[:record])
    apply_constraints_to_record(@record, :allow_autosave => true)
    before_create_save(@record)
    @record.raise_on_save_failure = false
    self.successful = @record.save
    raise Sequel::Rollback unless successful?
    after_create_save(@record)
    if nested?
      create_association_with_parent(@record) 
      register_constraints_with_action_columns(nested.constrained_fields)
    end
  end
end
do_new() click to toggle source

A simple method to find and prepare an example new record for the form May be overridden to customize the behavior (add default values, for instance)

# File lib/active_scaffold/actions/create.rb, line 82
def do_new
  @record = new_model
  apply_constraints_to_record(@record)
  if nested?
    register_constraints_with_action_columns(nested.constrained_fields)
  end
  @record
end

    return_to_main
  end
end
