Module: Card::Model::SaveHelper

Included in:
Card::Migration
Defined in:
lib/card/model/save_helper.rb

Overview

API to create and update cards. It is intended as a helper for "external" scripts (seeding, testing, migrating, etc) and not for internal application code. The general pattern is: All methods use the ActiveRecord !-methods that throw exceptions if somethings fails. All !-methods in this module rename existing cards to resolve name conflicts)

#ensure_card(name_or_args, content_or_args = nil) ⇒ Object Also known as: ensure

create if card doesn't exist updates existing card only if given attributes are different except the name

Examples:

if a card with name "under_score" exists

ensure_card "Under Score"                 # => no change
ensure_card "Under Score", type: :pointer # => changes the type to pointer
                                          #    but not the name

#ensure_card!(name_or_args, content_or_args = nil) ⇒ Object Also known as: ensure!

create if card doesn't exist updates existing card only if given attributes are different including the name For example if a card with name "under_score" exists then ensure_card "Under Score" renames it to "Under Score"

#ensure_trait(name, codename, args = {}) ⇒ Object

Creates or updates a trait card with codename and right rules. Content for rules that are pointer cards by default is converted to pointer format.

Examples:

ensure_trait "*a_or_b", :a_or_b,
             default: { type_id: Card::PointerID },
             options: ["A", "B"],
             input: "radio"
