how to get the data from nested object entity class to thymeleaf - spring-boot

Question

i have 2 entity class, parkingUser and parkingDetails,
user can have many parking details(one to many).
parkingUserobject contain:
[id, firstName, lastName,parkingDetails[id, entryDate,...,user_id(FK)]]
in parkingUser i had List of parkingDetails(its my FK)
#OneToMany(mappedBy = "parkingUsers", cascade = CascadeType.ALL, orphanRemoval = true)
private List<parkingDetails> parkingDetails = new ArrayList<parkingDetails>();
what i want to achive is to access the data of nested object,
like that:
parkingUser.getParkingDetails.getEntryTime()
this is my controller:
#GetMapping("/exitform")
public String exitForm(#RequestParam ("userId") int theId, Model model) {
parkingUsers parkingUsers = parkingUsersService.findByID(theId);
model.addAttribute("user",parkingUsers);
model.addAttribute("exitDateAndTime", new java.util.Date());
return "exit-form";
}
and my thymeleaf snift code:
<th:block th:object="${user}">
<form action="#" th:action="#{/saveDateAndTimeOfExitParking}" th:object="${user.parkingDetails}" method="POST">
<input type="hidden" th:field="*{id}"/>
<input type="text" th:field="*{firstName}">
<br>
<input type="text" th:field="*{lastName}">
<br>
<input type="text" th:field="*{license}">
<br>
<!-- i want to get the value of entryDate on parkingDetails object -->
<input type="text" th:field="*{user.parkingDetails.entryDate}">
<br>
<!-- i want to get the value of entryTime on parkingDetails object -->
<input type="text" th:field="*{user.parkingDetails.entryTime}">
<br>
<input type="text" th:value="${#dates.format(exitDateAndTime, 'dd-MM-yyyy')}">
<br>
<input type="text" th:value="${#dates.format(exitDateAndTime, 'HH:mm:ss')}">
<br>
<button type="submit" class="btn btn-info mb-11 col-15">Exit Car</button>
</form>
</th:block>
