Example 1 with ValueContext

use of com.vaadin.flow.data.binder.ValueContext in project furms by unity-idm.

the class AlarmFormView method prepareValidator.

private void prepareValidator(TextField nameField, ComboBox<String> allocationComboBox, IntegerField thresholdField, Checkbox checkbox, MultiselectComboBox<String> multiselectComboBox) {
    binder.forField(nameField).withValidator(value -> Objects.nonNull(value) && !value.isBlank(), getTranslation("view.project-admin.alarms.form.error.name")).bind(model -> model.name, (model, name) -> model.name = name);
    binder.forField(allocationComboBox).withValidator(Objects::nonNull, getTranslation("view.project-admin.alarms.form.error.allocation")).bind(model -> model.allocationId, (model, id) -> model.allocationId = id);
    binder.forField(thresholdField).withValidator(threshold -> threshold >= 1.0 && threshold <= 100.0, getTranslation("view.project-admin.alarms.form.error.threshold")).bind(model -> model.threshold, (model, threshold) -> model.threshold = threshold);
    binder.forField(checkbox).bind(model -> model.allUsers, (model, value) -> model.allUsers = value);
    binder.forField(multiselectComboBox).withValidator(emails -> emails.stream().noneMatch(email -> emailValidator.apply(email, new ValueContext()).isError()), getTranslation("view.project-admin.alarms.form.error.emails")).bind(model -> model.users, (model, policyFile) -> model.users = multiselectComboBox.getSelectedItems());
}

Example 2 with ValueContext

use of com.vaadin.flow.data.binder.ValueContext in project flow by vaadin.

the class NotEmptyValidatorTest method nonNullValueIsAllowed.

@Test
public void nonNullValueIsAllowed() {
    NotEmptyValidator<Object> validator = new NotEmptyValidator<>("foo");
    Object value = new Object();
    ValidationResult result = validator.apply(value, new ValueContext());
    Assert.assertFalse(result.isError());
    Assert.assertFalse(result.isError());
}

Example 3 with ValueContext

use of com.vaadin.flow.data.binder.ValueContext in project flow by vaadin.

the class NotEmptyValidatorTest method emptyValueIsDisallowed.

@Test
public void emptyValueIsDisallowed() {
    NotEmptyValidator<String> validator = new NotEmptyValidator<>("foo");
    ValidationResult result = validator.apply("", new ValueContext());
    Assert.assertTrue(result.isError());
    Assert.assertEquals("foo", result.getErrorMessage());
}

Example 4 with ValueContext

use of com.vaadin.flow.data.binder.ValueContext in project flow by vaadin.

the class ValidatorTestBase method assertFails.

protected <T> void assertFails(T value, String errorMessage, Validator<? super T> validator) {
    ValidationResult result = validator.apply(value, new ValueContext(localeContext));
    Assert.assertTrue(result.isError());
    Assert.assertEquals(errorMessage, result.getErrorMessage());
}

Example 5 with ValueContext

use of com.vaadin.flow.data.binder.ValueContext in project flow by vaadin.

the class BeanValidator method apply.

/**
 * Validates the given value as if it were the value of the bean property
 * configured for this validator. Returns {@code Result.ok} if there are no
 * JSR-303 constraint violations, a {@code Result.error} of chained
 * constraint violation messages otherwise.
 * <p>
 * Null values are accepted unless the property has an {@code @NotNull}
 * annotation or equivalent.
 *
 * @param value
 *            the input value to validate
 * @param context
 *            the value context for validation
 * @return the validation result
 */
@Override
public ValidationResult apply(final Object value, ValueContext context) {
    Set<? extends ConstraintViolation<?>> violations = getJavaxBeanValidator().validateValue(beanType, propertyName, value);
    Locale locale = context.getLocale().orElse(Locale.getDefault());
    Optional<ValidationResult> result = violations.stream().map(violation -> ValidationResult.error(getMessage(violation, locale))).findFirst();
    return result.orElse(ValidationResult.ok());
