Date Validation - message formatting of the date
------------------------------------------------
Key: WICKET-2540
URL: https://issues.apache.org/jira/browse/WICKET-2540
Project: Wicket
Issue Type: Improvement
Components: wicket
Reporter: Jeff Schneller
Priority: Minor
Have the ability to pass a date format string to the validator so that the
dates will format how the developer desires when a validation error is hit. I
have included an example of how I worked around the problem. Feel free to use
this as a starting point.
Example:
public class CustomMinimumDateValidator extends AbstractValidator<Date>
{
private final Date minimum;
private final String format;
public CustomMinimumDateValidator(Date minimum, String format) {
this.minimum = minimum;
this.format = format;
}
@Override
protected void onValidate(IValidatable<Date> validatable) {
Date value = validatable.getValue();
if (value.before(minimum))
{
error(validatable);
}
}
@Override
protected Map<String, Object> variablesMap(IValidatable<Date>
validatable)
{
final Map<String, Object> map =
super.variablesMap(validatable);
SimpleDateFormat sdf = new SimpleDateFormat(format);
String minimumString = sdf.format(minimum);
map.put("mindate", minimumString);
map.put("inputdate",
sdf.format(validatable.getValue()));
return map;
}
@Override
protected String resourceKey()
{
return "CustomMinimumDateValidator.minimum";
}
}
