@Range

Overview

@Range (or its alias @Between) enforces the constraint that the value of the input element must be greater than or equal to one specified value and lesser than equal to another specified value. Meaning, the value of the input element must lie between a certain range of values (both values inclusive).

Syntax

Syntax for @Range is:

@Range(min=min-value, 
       max=max-value , [label=label-text] , 
                       [message=message-text] , 
                       [groups=array-of-group-names])

Parameters

Name	Type	Required	Description
min	Integer	yes	A required parameter that specifies the minimum acceptable value of the field.
max	Integer	yes	A required parameter that specifies the maximum acceptable value of the field.
label	String	no	An optional parameter that specifies the label for this input element. Labels are a way to provide friendly names to input elements. If the constraint fails to validate, the value in this field will be used in the default error message. If the constraint has a custom error message which contains {labe}, the value of this parameter will be substituted in the place of {label}.
message	String	no	An optional parameter that specifies the error message to use when this constraint fails. The value for this field can contain interpolations of parameters used by the constraint . For example: {label} needs to be between {min} and {max}.
groups	Array	no	An array of group names that specifies the validation groups that this constraint belongs to.

Examples

Basic usage:

<input id = "age"
       name = "age"
       type = "text"
       data-constraints = '@Range(min=5, max=10)' />

Usage with optional parameters:

<input id = "age"
       name = "age"
       type = "text"
       data-constraints = '@Between(min=5, max=10, 
                                    label="age", 
                                    message="This game is only suitable for children between the ages of {min} and {max}, 
                                    groups=[FirstGroup, SecondGroup, ThirdGroup]"' />
