I was trying to show the model with dataTable in Spring but how can i get the value from the #ManyToOne relationship ? Below is my code
Model file - I want to get
"private long usersId" from Users model and "private long roles_id" from Role model but i don't know how to get it out

I'm trying to add data in table via server but unable to succeed. I tried many things but nothing worked. I'm getting the data from the server but unable to populate that in table.. can someone please help me out?
I'm getting this :
"DataTables warning: table id=particlarsTable - Invalid JSON response. For more information about this error, please see http://datatables.net/tn/1"
Let me explain my code first:
(In View)
When I click on "Add New Particular" button, bootstrap modal will popup with input fields, those fields will send to the server then again back to view and populate the table with the same data without refreshing the whole page.
I'm stuck on the last stage, I'm getting the data on UI/View in ajax success handler but unable to load that data in table.
here is my view :
<form class="form-horizontal" method="post" id="createAdHocForm">
<div class="row">
<div class="col-md-3">
<div class="form-group">
<label>Select Flat</label>
<select asp-for="AdHocInvoice.FlatRid" asp-items="#(new SelectList(Model.Flats,"FlatRid","FlatNumber"))" class="form-control form-control-sm selectpicker" data-live-search="true">
<option selected disabled value="">Select One</option>
</select>
</div>
</div>
</div>
<table class="table table-sm table-responsive-md nowrap w-100" id="particlarsTable">

<tr>
<th>Particulars</th>
<th>Amount</th>
<th></th>
</tr>
</thead>
<tbody class="bg-white">
#foreach (var item in Model.AdHocInvoice.FlatInvoiceItems)
{
<tr>
<td>#item.Particular</td>
<td>#item.Amount</td>
<td></td>
</tr>
}
</tbody>
</table>

bootstrap modal to fill the table :

Action Method on controller:
public JsonResult AddParticular(string particular, decimal amount)
{
_flatInvoiceViewModel.AdHocInvoice.FlatInvoiceItems.Add(new FlatInvoiceItem { Particular = particular, Amount = amount });
return Json(_flatInvoiceViewModel);
}
Class/Model:
public class FlatInvoiceItem
{
public Guid FlatInvoiceItemRid { get; set; }
public Guid FlatInvoiceRid { get; set; }
public Guid FundRuleRid { get; set; }
public string Particular { get; set; }
public decimal Amount { get; set; }
}
NOTE: this code is in initial phase, I need that input data on server for further process(will add code later) so don't want to use $.('#table_body_id').append("<tr>..</tr>"); type of code.
1.Firstly,reload() is used to send request back to the method which display the DataTable initially(e.g. name this method Test).
2.Secondly,From your AddParticular method,you just add a data to the list but the lifetime is just one request,so when you reload to Test method,the list still contains the initial data without new data.
Conclusion: I suggest that you could save data to database.And get data from database.
Here is a working demo about how to use DataTabale:
1.Model:
public class Test
{
public int Id { get; set; }
public AdHocInvoice AdHocInvoice { get; set; }

I am using spring boot+thymeleaf+neo4j. Everything is working fine except that thymeleaf is not able to resolve a few of the attributes of the 'product' variable used in the th:each block in the template product_grid.html, which includes th:src="${product.URL}", th:text="${Product.title}" and the th:action="#{/product/(${Product.getId()})}" expression in form tag. The th:text="${Product.Price}" is working. When I check the code produced in the browser the src tag is empty (src:""), the text attribute containing the title tag is not shown in the browser. The th:action works fine but when I click the button defined inside the form, the url changes to http://localhost:8080/product/?btn=View+Product
instead of the following code which is shown in the browser console
http://localhost:8080/product/?1
Note: I am trying to get the image url from a field which is stored in neo4j database. The project directory is:

Welcome to SO.
Include setX methods for your variables in the Product class. Thymeleaf needs these to bind.
IMO, a great way to do this is to use Project Lombok and simply annotate your class with #Data. Then you won't even need to specify getters or setters (or your toString()) at all.
Use lower-case for your variables since by convention variables with a capital first letter refers to the class, not an instance variable.
As mentioned, use POST instead of GET in your form since you are submitting data.
Use the shorthand #GetMapping and #PostMapping to make it easier to read.
I'm trying to update an entity with a particular mapping :
#Entity
#Table(name = "obs_structure2")
#JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
public class Structure implements Serializable{
private String id;
private String tag;
private String description;
private Set<Version> parentVersions = new HashSet<>();
private List<StructureElement> children = new ArrayList<>();
private List<StructureElement> slaves = new ArrayList<>();
private PersistenceSignature signature = new PersistenceSignature();
#OneToMany(mappedBy = "parentStructure")
public List<StructureElement> getChildren() {
return children;
}
public void addChild(StructureElement se)
{
if(this.children.contains(se))
{
this.children.add(se);
}
}
and
#Entity
#Table(name = "obs_structure_element2")
#JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id")
public class StructureElement implements Serializable{
private long id;
private String tag;
private String description;
private boolean repetitive = false;
private boolean optional = false;
private Integer position = 1;
private Structure parentStructure;
private Structure typeStructure;
private PersistenceSignature signature = new PersistenceSignature();
#ManyToOne
#JoinColumn(name = "parent_id")
#JsonIgnore
public Structure getParentStructure() {
return parentStructure;
}
and this is my controller :
#PutMapping("/update")
public StructureElement update(#RequestBody StructureElement se){
logger.info("Call to StructureElementController.update with se = " + se);
this.connectToDatabase();
StructureElement updatedSE;
try{
boolean exists = this.repository.exists(se.getId());
if(!exists){
logger.error("Could not find StructureElement to update. se = " + se);
return null;
}
updatedSE = this.repository.save(se);
logger.info("Updated SE = " + updatedSE);
}catch (Exception e){
logger.error("Could not update structure element. se = " + se, e);
return null;
}
return updatedSE;
}
When I try to update an element the parentStructure is overwritten to null.
If I delete the #JsonIgnore annotation I'm getting this StackOverflow error:

Well, I've looking in some articles and changed the way I update the entity:
#PutMapping("/update")
public StructureElement update(#RequestBody StructureElement se){
StructureElement databaseElement;
logger.info("Call to StructureElementController.update with se = " + se);
this.connectToDatabase();
try{
databaseElement = this.repository.findOne(se.getId());
if(databaseElement == null){
logger.error("Could not find StructureElement to update. se = " + se);
return null;
}
// Update
databaseElement.setDescription(se.getDescription());
databaseElement.setTag(se.getTag());
databaseElement.setOptional(se.isOptional());
databaseElement.setRepetitive(se.isRepetitive());
databaseElement.getSignature().setModificationDate(new Date());
databaseElement = this.repository.save(databaseElement);
logger.info("Updated SE = " + databaseElement);
}catch (Exception e){
logger.error("Could not update structure element. se = " + se, e);
return null;
}
return databaseElement;
}
Now this works.
Seems that Spring data JPA doesnt want to update an entity like a simple JPA EntityManager....
In this jsp, I have used 2 form actions, one to save the role(table:defining role), and other to call the drop list from other table(table: solutionList).
After clicking on submit, it is not doing anything.
If i remove this form(solutionMaster.html)
Im getting this error " Invalid property 'sMName' of bean class [com.mode;.definingrole]: Bean property 'sMName' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?.
Yes, I know the reason, Because the column 'sMName' was not the part of defining role table. what to do with this.
The Thing i want to know is,
Can we create form inside form?
2.Without creating another form, How can i get the column values of other table to defining role table?
Please help.
Thanks in advance.!!!

You are trying to populate list inside form under the tag of form. Which is wrong approach. You won't get the value from /solutionlist.html by your form. You have to call at least a GET if you want to use /solutionlist.html controller.
If i think So then you have to do the following
You don't need the '/solutionlist.html' controller.
Just bind the ArrayList solutionList into model in the controller method where the form page served. I mean the GET method of Controller where the given form is served.
ArrayList<String> solutionList=TemplateService.getSolutionListForTemplate();
model.put("solutionList", solutionList);
You will get that solutionList directly to your form as value. So, modify the select part of your form as follows
<select name="solutions"path="Solutions">
<c:forEach items="${solutionList}" var="solution">
<option value="${solution}">${solution}</option>
</c:forEach>
</select>
I have a page that displays the list of all the journals available. I want to write a thymeleaf expression language that highlights the already subscribed journals using there journal id . So for all the subscribed journals the text for the hyper-link href should be "Unsubscribe" and vice verse if its not subscribed.

Controller
#Controller
public class SubscriptionController {
#Autowired
private SubscriberService subscriberService;
#RequestMapping(value = "/subscribe", method = RequestMethod.POST)
String subscribe(Model model, #RequestParam("journalId") Integer journalId) {
JournalToken token = (JournalToken) SecurityContextHolder.getContext().getAuthentication();
Account user = (Account) token.getCredentials();
model.addAttribute("user", user);
Journal journal = this.subscriberService.findJournalById(journalId);
this.subscriberService.subscribeJournalForSubscriber(journal, user);
return "redirect:subscriptions";
}
#RequestMapping(value = "/subscriptions", method = RequestMethod.GET)
String list(Model model) {
JournalToken token = (JournalToken) SecurityContextHolder.getContext().getAuthentication();
Account user = (Account) token.getCredentials();
model.addAttribute("user", user);
ArrayList<Journal> journals = this.subscriberService.FindAllJournals();
model.addAttribute("journals", journals);
StringBuilder sub = new StringBuilder();
ArrayList<Subscription> subscribed = this.subscriberService.getSubscribedJournalsForSubscriber(user);
model.addAttribute("subscriptions", subscribed);
return "subscriptions";
}
}
Model subscriptions
#Entity
#Table(uniqueConstraints={#UniqueConstraint(columnNames={"userId", "journalId"})})
public class Subscription {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
#Version
private Integer version;
private Integer userId;
private Integer journalId;
public void setId(Integer id) {
this.id = id;
}
public Integer getId() {
return this.id;
}
public void setVersion(Integer version) {
this.version = version;
}
public Integer getVersion() {
return this.version;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public Integer getUserId() {
return this.userId;
}
public void setJournalId(Integer journalId) {
this.journalId = journalId;
}
public Integer getJournalId() {
return this.journalId;
}
}
you can change your arrayList subscribed to have only the ids of journals (more optimised).
So, in the controller you can have something like this
ArrayList<Integer> subscribed =
this.subscriberService.getSubscribedJournalsForSubscriber(user); //modify it so it returns the journals ids instead of the whole object(Subscription)
then in the thymeleaf change the anchor with something like this
<a id="href" th:href="'javascript:subscribe(\'' + ${journal.id} + '\');'">
<span th:if="${#lists.contains(subscriptions, journal.id) }" th:text="Unsubscribe"> Unsubscribe </span>
<span th:if="not ${#lists.contains(subscriptions, journal.id) }" th:text="Subscribe"> Subscribe </span>
</a>
Have a look at the documentation of thymeleaf http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html
