#vraptor-modelform
A plugin to generate html forms based on model classes.
##Installing
Add to your pom:
<dependency>
<groupId>br.com.caelum.vraptor</groupId>
<artifactId>vraptor-modelform</artifactId>
<version>4.0.0-SNAPSHOT</version>
</dependency>##Using it
Suppose you have the following model class:
public class User {
private String name;
private Calendar birthday;
//getters and setters or constructor with fields
}To create a model based on User class, inject a ModelForm instance of User in your controller:
public class UserController {
@Inject
private ModelForm<User> form;
@Inject
private Result result;
@Get
public void add() {
result.include("form", form);
}
}Then, in your in the add.jsp file, you can use the form to generate the html to create a new user:
<%@ taglib prefix="forms" uri="http://vraptor.org/jsp/taglib/modelform" %>
<html>
<body>
<forms:formFor form="${form}"/>
</body>
</html>
This will generate the required html form to create a new user.
Now, in your controller you can create a method receiving the User built with the form data:
public class UserController {
//fields and other methods...
@Post
public void add(User user) {
System.out.println("user received from form: " + user);
}
}
