Helper Traits for Sebastian Bergmann's Money
Usage
This adds "value" properties to your models, using traits. This is accomplished with ValueTrait and CurrencyTrait. The first adds the methods responsible for working with the Money objects, while CurencyTrait handles keeping tabs on which currency to use.
// Model Class
use Harp\Harp\AbstractModel;
use Harp\Money\ValueTrait;
use Harp\Money\CurrencyTrait;
class User extends AbstractModel
{
use ValueTrait;
use CurrencyTrait;
public static function initialize($config)
{
// ...
ValueTrait::initialize($config)
CurrencyTrait::initialize($config)
}
// ...
}
Database Table:
┌─────────────────────────┐
│ Table: User │
├─────────────┬───────────┤
│ id │ ingeter │
│ name │ string │
│ currency* │ string │
│ value* │ integer │
└─────────────┴───────────┘
* Required fields
Methods
ValueTrait Methods
| Method | Description |
|---|---|
| getValue() | Return a new Money object that represents the value property in the model, using the currency object returned from a "getCurrency" method. |
| setValue(Money $money) | Set the parent model |
CurrencyTrait Methods
| Method | Description |
|---|---|
| getCurrency() | Return a new Currency object, based on the currency property in the model |
Freezable
Using the FreezableTrait will allow you to easily freeze values in the database. You will need to implement performFreeze and performUnfreeze methods. Database Table:
┌─────────────────────────┐
│ Table: User │
├─────────────┬───────────┤
│ id │ ingeter │
│ name │ string │
│ isFrozen* │ integer │
└─────────────┴───────────┘
* Required fields
FreezableTrait Methods
| Method | Description |
|---|---|
| freeze() | call the performFreeze method if the model is not "frozen", e.g. isFrozen property is false. And set isFrozen to true after performFreeze is called |
| unfreeze() | call the performUnfreeze method if the model is "frozen", e.g. isFrozen property is true. And set isFrozen to false after performUnfreeze is called |
Freezable Value
This combines ValueTrait and FreezableTrait to allow you to "freeze" values in the model. It requires a getSourceValue which returns the dynamic value as a Money object. After "freeze" is called the result of getSourceValue is stored in the database, and subsequent calls to "getValue" will return the frozen value.
Additionally if the price from getSourceValue is with a different currency, use Converter class to convert the to the target currency.
FreezableTrait Methods
| Method | Description |
|---|---|
| freeze() | From FreezableTrait |
| unfreeze() | From FreezableTrait |
| setValue() | From ValueTrait |
| getValue(Money $money) | From ValueTrait |
| getConvertedSourceValue() | return a Money object from getSourceValue converted to a proper currency with |
| performFreeze() | implements a FreezableTrait requirement, saves the value |
| performUnfreeze() | implements a FreezableTrait requirement, clears the value frozen in the database |
