do_create(options = {}) 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(options = {})
  attributes = options[:attributes] || params[:record]
  active_scaffold_config.model.transaction do
    @record = update_record_from_params(new_model, active_scaffold_config.create.columns, attributes)
    apply_constraints_to_record(@record, :allow_autosave => true)
    create_association_with_parent(@record) if nested?
    before_create_save(@record)
    # errors to @record can be added by update_record_from_params when association fails to set and ActiveRecord::RecordNotSaved is raised
    self.successful = [@record.keeping_errors { @record.valid? }, @record.associated_valid?].all? # this syntax avoids a short-circuit
    create_save(@record) unless options[:skip_save]
  end
rescue ActiveRecord::ActiveRecordError => ex
  flash[:error] = ex.message
  self.successful = false
  @record ||= new_model # ensure @record exists or display form will fail
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 84
def do_new
  @record = new_model
  apply_constraints_to_record(@record)
  create_association_with_parent(@record) if nested?
  @record
end
