Hi, i have a ManyToMany relationship [Basket has many Products] and trying to use checkbox to track changes from the Views ...
Product Entity
@Entity @Table(name = "PRODUCT") public class Product implements java.io.Serializable { // Fields @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "ID", unique = true, nullable = false) private Integer entityId; @Column(name = "NAME") private String name; @Column(name = "CODE", unique=true) private String productCode; @Column(name = "DESCRIPTION") private String description; @Column(name = "PRICE") private Double price; @Column(name = "NOT_IN_BASKET") // This is the field which i hope to use for checkbox private boolean notInBasket;
Jsp
form
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> <%@ taglib prefix="security" uri="http://www.springframework.org/security/tags"%> <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%> <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <link rel="stylesheet" href="<c:url value="/styles/springsource.css"/>" type="text/css" /> <title>Shopping Basket: Basket Items</title> </head> <body> <div id="main_wrapper"> <h1>Shopping Basket</h1> <form:form commandName="basket"> <table> <tr> <td> <table> <tr> <td>ShoppingBasket:</td> <td>${basket.reference}</td> </tr> </table> </td> </tr> <tr> <td> <table width="600" border="1" cellspacing="0" cellpadding="2" border="0"> <thead> <tr> <td>Products:</td> </tr> <tr> <td>Product Name</td> <td>Product Code</td> <td>Description</td> <td>Price</td> <td>Remove</td> </tr> </thead> <tbody> <c:forEach items="${basket.products}" var="product"> <tr> <td>${product.name}</td> <td>${product.productCode}</td> <td>${product.description}</td> <td>${product.price}</td> <td><form:checkbox path="notInBasket" value="${product.notInBasket}"/></td> </tr> </c:forEach> </tbody> </table> </td> </tr> <tr> <td> <input type="submit" value="Remove Items"/> </td> </tr> <tr> <td> <a href="<c:url value="/views/login.jsp"/>">Return to Home Page</a> </td> <td> <a href="<c:url value="/j_spring_security_logout"/>">Logout</a> (<security:authentication property="principal.username" />) </td> </tr> </table> </form:form> </div> </body> </html>
Does form:checkbox path="notInBasket" requires me to have yet another field on basket Entity? how do i change Product.notInBasket when the box is checked? Or how should i do this better
