Using Realm.io to store money values

Question

I\'m starting to play with Realm.io in an Android app that I\'m writing. In one of my data objects, I\'m required to store a currency value. Previously I had stored the valu

Answer 1

That could work, but would probably be suboptimal if do calculations on your current BigDecimal objects.

You could also use the @Ignore annotation to provide a wrapper method for your custom objects like this:

public class Money extends RealmObject {

  private String dbValue;
  @Ignore private BigDecimal value;

  public String getDbValue() {
      return dbValue;
  }

  public void setDbValue(String dbValue) {
      this.dbValue = dbValue;
  }

  public BigDecimal getValue() {
     return new BigDecimal(getDbValue());
  }

  public void setValue(BigDecimal value) {
      setDbValue(value.toString());
  }
}

It is not perfect as you need to expose the *dbValue() methods, but it should work.

I would also suggest going to https://github.com/realm/realm-java/issues and make a feature request for this as BigDecimal is probably one of those java classes used by so many that it could warrant native Realm support, just like Date has.
