So I am working on a small project (I'm a newbie) and I have been unable to access my fields declared in my model class from my view in Thymeleaf. I checked the documentation and I am certain I am doing everything as it should be but for some reason, IntelliJ gives me a "cannot resolve field" error. I checked here and there online and saw that It used to be an issue with IntelliJ which was supposedly fixed in their 2017.X version but I still get a similar error(I am using IntelliJ 2022.2.4). Can anyone please help?
This is my view page and I get an error at the level of th:field="*{loginDate}"
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org" >
<head>
<meta charset="UTF-8">
<title>ADD NEW RECORD</title>
<link rel="stylesheet" type="text/css" th:href = "@{/webjars/bootstrap/css/bootstrap.min.css}"/>
</head>
<body>
<div class="container-fluid text-center">
<div><h2>ADD NEW RECORD</h2></div>
<form th:action="@{students/save}" th:object="${newStudent}" method="post" >
<div class ="border">
<div class="form-group row">
<label class="col-sm-4 col-form-label">Date</label>
<div class="col-sm-8">
<input type="date" **th:field="*{loginDate}"** class="form-control">
</div>
</div>
</div>
</form>
</div>
</body>
</html>
Here is my controller:
package com.sfsb.studentsSFSB.students.controller;
import com.sfsb.studentsSFSB.students.model.Students;
import com.sfsb.studentsSFSB.students.service.StudentsServiceImpl;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import java.util.List;
@Controller
public class StudentController {
private StudentsServiceImpl service;
public StudentController(StudentsServiceImpl service) {
this.service = service;
}
@GetMapping("")
public String showHomePage(){
return "index";
}
@GetMapping("/students/new")
public String showForm(Model model){
model.addAttribute("newStudent", new Students());
return "student_form";
}
@GetMapping("/students")
public String showStudentsList(Model model){
List<Students> listStudents = service.findAll();
model.addAttribute("listStudents", listStudents);
return "students";
}
}
And here is my model class
package com.sfsb.studentsSFSB.students.model;
import jakarta.persistence.*;
import org.springframework.format.annotation.DateTimeFormat;
import java.time.Duration;
import java.time.LocalDate;
import java.time.LocalTime;
import java.time.format.DateTimeFormatter;
@Entity
@Table(name = "students")
public class Students {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
@Column(name = "FirstName")
private String firstName;
@Column(name = "LastName")
private String lastName;
@Column(name = "Date")
@DateTimeFormat(pattern = "yyyy-MM-dd")
private LocalDate loginDate;
@Column(name = "LoginTime")
@DateTimeFormat(pattern = "HH:mm")
private LocalTime loginTime;
@Column(name = "BreakPeriod")
@DateTimeFormat(pattern = "HH:mm")
private LocalTime breakPeriod;
@Column(name = "LogoutTime")
@DateTimeFormat(pattern = "HH:mm")
private LocalTime logoutTime;
@Column(name = "HoursWorkedPerDay")
@DateTimeFormat(pattern = "HH:mm")
private LocalTime workHoursPerDay;
@Column(name = "Task")
private String task;
@DateTimeFormat(pattern = "HH:mm")
private LocalTime workHoursPerWeek;
@DateTimeFormat(pattern = "HH:mm")
private LocalTime totalHoursForCurrentContract;
//@DateTimeFormat(iso = DateTimeFormat.ISO.TIME) if above does not work
@DateTimeFormat(pattern = "HH:mm")
private LocalTime hoursLeftOnCurrentContract;
//Method to calculate work hours per day based on login,break and logout values
public LocalTime calculateWorkHoursPerDay(){
//DateTimeFormatter Formatter = DateTimeFormatter.ofPattern("H:mm");
Duration breakDuration = Duration.between(LocalTime.MIDNIGHT, breakPeriod);
Duration workDuration = Duration.between(loginTime,logoutTime).minus(breakDuration);
String workHoursInString = LocalTime.MIDNIGHT.plus(workDuration).toString();
workHoursPerDay = LocalTime.parse(workHoursInString);
return workHoursPerDay;
}
}
