Spring MVC Multiple ModelAttribute On the Same Form

Asked 5/11, 2012 at 23:57 Answered 28/5, 2018 at 7:54

I have a form with two ModelAttributes one is citizens and the other is punishment. The two objects are separated by jquery tabs. I am having problems in getting the items on the form to display properly some are being displayed and some are not. I mean the html elements.

I am not sure how the Controller would look when there is multiple ModleAttributes on the page. Under is a sample of the code:

Page

<title>Citizen Registration</title>

    </head>

    <body>  
        <div id="tabs"> 

        <ul>
            <li><a href="#tab1">Citizen Registration</a></li>
            <li><a href="#tab2">Punishment</a></li>
        </ul>


        <div id="tab1">
            <form:form id="citizenRegistration" name ="citizenRegistration" method="post" modelAttribute="citizens" action="citizen_registration.htm">
                <div id="divRight" class="mainDiv">             
                    <div class="divGroup" id="divCharInfo"> 
                    <fieldset>  
                    <legend>Characteristics Info</legend>
                            <ol>    
                                <li><form:label for="photo" path="photo">Select Photo</form:label>
                                    <form:input path="photo" type="file" id="photo" title="Upload a photo"/><form:errors path="photo" id="errors"/></li>

                                <li>
                                    <label>Select Gender</label>
                                    <form:select path="genderId" id="genderId" title="Select Your Gender">
                                    <form:options items = "${gender.genderList}" itemValue="genderId" itemLabel="genderDesc" />
                                    </form:select>

                                </li>

                                </li>

@RequestMapping(value="citizen_registration.htm", method = RequestMethod.GET)
    public ModelAndView loadPage(HttpServletRequest request,

                                 @ModelAttribute Citizens citizens, @ModelAttribute Punishment punishment,
                                 BindingResult result,
                                 ModelMap m, Model model) throws Exception {

//code here

return new ModelAndView("citizen_registration");

This is my code however when i run it nothing in tab2 is displayed andnot all elements in tab1 is shown.

I don't think so if you can bind multiple models using the Spring form. In fact you should take a look in the spring binding form. http://static.springsource.org/spring/docs/1.1.5/taglib/tag/BindTag.html Take a look in the sample code. I have not tested the code. Let know in case of any issues.

Model

public class User{

private String username;
private String password;

..Setter and Getters
}

public class UserProfile{
private String firstName;
private String lastName;

setter and getter
}

Controller

@Controller
public class MyController{
    @RequestMapping(....)
    public String newAccountForm(ModelMap map){
        User user = new User(); //Would recommend using spring container to create objects
        UserProfile profile = new UserProfile();

        map.addAttribute('user', user);
        map.addAttribute('profile', profile);

        return "form"
    }




     @RequestMapping(....)
        public String newAccountForm(@ModelAttrbite('User')User user, BindingResult resultUser, @ModelAttribute('UserProfile')UserProfile userProfile, BindingResult resultProfile){

//Check the binding result for each model. If not valid return the form page again
//Further processing as required.

        }
    }

JSP

<%@taglib  uri="http://www.springframework.org/tags" prefix="spring">

<form action="" method="post">

<spring:bind path="user.username">
   <input type="text" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>

<spring:bind path="user.password">
   <input type="password" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>

<spring:bind path="profile.firstName">
   <input type="text" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>
<spring:bind path="profile.lastName">
   <input type="text" name="${status.expression}" value="${status.value}"><br />
        </spring:bind>

<input type="submit" value="Create"/>
</form>

what about if you create one class that references these two classes will that work? – Mumford 6/11, 2012 at 0:4

Well if you want to go along the standard spring forms. Then to bind multiple models you can create a Form Class containing the models. But I found the spring binding form easier as they remove the requirement to implement an extra class. Moreover, the validation for each model can be done separately. Also, it also provides with the functionality to bind nested models. – Hara 6/11, 2012 at 0:12

I understand what you're saying what would you recommend just use separate forms? – Mumford 6/11, 2012 at 0:16

Just use spring bind forms. I will post some sample usage to help you. – Hara 6/11, 2012 at 0:19

i am new to using spring and i would like to use something that is most efficient to develop and maintain cause i am seeing problems if i use a combine class and i want to query the form or even update – Mumford 6/11, 2012 at 0:20

i noticed your spring form tags are different from the ones i used. Is these the tags you would have to use when you return an object to the form so that the object would bind to the fields? What i am asking is if your query the database and return an object to the page is this the tags you would need to use to bind whats in the database to the view? – Mumford 6/11, 2012 at 0:41

let us continue this discussion in chat – Hara 6/11, 2012 at 0:46

Not working for me. The form still seems to need a commandName, and the different paths don't work for the second object. – Suborder 21/5, 2014 at 19:53

How about doing one standalone class with all these data types and than make some transformation? – Elurd 27/9, 2016 at 13:20

I already gave alternate approach in this link here

<form:form method="POST" modelAttribute="applicationGeneralInformation">
  <div class="section2">
    <h2>General Informaion</h2>

    <form:input type="hidden" path="id" id="id"/>

    <label for="app_func_desc">Description</label>: <form:input type="text" id="app_func_desc"
                                                                       path="functionalDescription"/><br/>
   <label for="app_sec_func">Functions</label>: <form:input type="text" id="app_sec_func"
                                                                  path="securityFunctions"/><br/>
