Im trying push object into List im able to push value to normal fields, Following is the code for binding value i have used: Job Model

public class Job {
    public Job(String name) {
        super();
        this.name = name;
    }

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Candidate Model

public class Candidate {
    
    private String candidatename;
    private List<Job> jobs;
    
    public String getCandidatename() {
        return candidatename;
    }

    public void setCandidatename(String candidatename) {
        this.candidatename = candidatename;
    }

    public List<Job> getJobs() {
        return jobs;
    }

    public void setJobs(List<Job> jobs) {
        this.jobs = jobs;
    }
}

candidatedetail.html

    <form class="form-horizontal" th:action="@{/savejobhistory}" method="post" th:object="${candidate}">
        <label>Candidate name:</label>
        <input type="text" th:field="*{candidatename}" /><br/>
        <button type="submit" class="btn btn-default">Submit</button>
    </form>

candidatejob.html

    <h2>Candidate Details!</h2>
    <span>Note:</span><span th:text="${candidate.candidatename}"></span><br/>

Controller.java

@GetMapping("/emp")
public String test(Model model) {
    Candidate candidate = new Candidate();
    model.addAttribute("candidate", candidate);
    return "candidatedetail";
}

@PostMapping("/savejobhistory")
public String sendForm(@ModelAttribute("candidate") Candidate candidate) {
    System.out.println("Inisde Meth");
    System.out.println(candidate.getCandidatename());
    return "candidatejob";
}

how to push to list i tried following and failed

<input type="text" 
                placeholder='Company Name'  class="form-control" th:field="*{candidate.jobs}" th:value="${job.name}"/></td>
                    <label th:text="${job.name}"></label> 

CodePudding user response：

You can use for each using the following format as an example :

        <tr th:each="Jobs : ${yourJobList}">
            <td><span th:text="${job.yourjobfield1}"></span></td>
            <td><span th:text="${job.yourjobfield2}"></span></td>
        </tr>

This will multiply the above block of elements for each job in your list.

CodePudding user response：

This tutorial can help explain how to index into an array when using a form. th:field="*{jobs[${0}].name}" is incorrect. If you want to specify the index it should look like this:

th:field="*{jobs[0].name}"

or if you want to use a variable:

th:field="*{jobs[__${variable}__].name}"

(you must use double underscores __ to do preprocessing in this case.)
