I have problem with paginate, I use grails 2.4.4
This my index.gsp:
<%# page contentType="text/html;charset=UTF-8" %>
<html>
<head>
<title></title>
</head>
<body>
<div>
<g:paginate controller="user" action="index" total="${userTotal}"/>
</div>
</body>
</html>
This is my controller:
class UserController {
def index() {
List<User> users = User.findAll()
render(view: "index", model: [users: users, userTotal: 4])
}
}
In the console I don't have any error and in my page I see nothing.
Array users isn't empty, I checked.
render(view: "index", model: [users: users, userTotal: 4])
You have hardcoded userTotal to be 4. The paginate tag defaults to 10 items per page, so pagination is not required.
If you are concerned about pagination then User.findAll() is probably a bad idea because it will return all of the data.
Default scaffolding will do something like this which is a better idea...
Controller action:
def index(Integer max) {
params.max = Math.min(max ?: 10, 100)
respond userService.list(params), model:[userCount: userService.count()]
}
GORM Data Service:
import grails.gorm.services.Service
#Service(User)
interface UserService {
User get(Serializable id)
List<User> list(Map args)
Long count()
void delete(Serializable id)
User save(User user)
}
The relevant GSP:
<!DOCTYPE html>
<html>
<head>
<meta name="layout" content="main" />
<g:set var="entityName" value="${message(code: 'user.label', default: 'User')}" />
<title><g:message code="default.list.label" args="[entityName]" /></title>
</head>
<body>
<g:message code="default.link.skip.label" default="Skip to content…"/>
<div class="nav" role="navigation">
<ul>
<li><a class="home" href="${createLink(uri: '/')}"><g:message code="default.home.label"/></a></li>
<li><g:link class="create" action="create"><g:message code="default.new.label" args="[entityName]" /></g:link></li>
</ul>
</div>
<div id="list-user" class="content scaffold-list" role="main">
<h1><g:message code="default.list.label" args="[entityName]" /></h1>
<g:if test="${flash.message}">
<div class="message" role="status">${flash.message}</div>
</g:if>
<f:table collection="${userList}" />
<div class="pagination">
<g:paginate total="${userCount ?: 0}" />
</div>
</div>
</body>
</html>
If you really don't want to use a service (highly recommended that you do) then you could change the controller to do something like this...
params.max = Math.min(max ?: 10, 100)
respond User.list(params), model:[userCount: User.count()]
It is my solution:
gsp:
<div class="content scaffold-list">
<g:form controller="user" action="index">
<label>Input user's name:</label>
<div class="form-group">
<g:textField name="userName"/>
<g:submitButton name="search"/>
</div>
<g:each var="user" in="${users}">
<p>User with name: ${user.name}</p>
</g:each>
</g:form>
<div class="pagination">
<g:paginate controller="user" action="index"
max="5" total="${userCount}"/>
</div>
</div>
controller:
def index(String userName) {
initUsersAndPokemons()
PagedResultList users = fourthService.findUsersByName(
userName,
params.int('max', 5),
params.int('offset', 0))
[users: users, userCount: users.getTotalCount()]
}
service:
PagedResultList findUsersByName(String userName, int max, int offset) {
BuildableCriteria bc = User.createCriteria()
bc.list(max: max, offset: offset) {
like('name',userName)
}
}

I'm a beginner and I came across an anomaly that I cant comprehend. From my point of view everything seems to be fine but I keep getting the same empty response when I perform a search in my MVC WebApp.
Take a look at my code. Any help would be greatly appreciated.
MY CONTROLLER
#Controller
public class ControllerACP {
#RequestMapping("/search")
public String Homea(Model model, #RequestParam(name = "query") String search) {
model.addAttribute("clients", clientRepository.search(search));
System.out.println(clientRepository.search(search)); // TO DISPLAY CONTENT ON CONSOLE
System.out.println(search); // ALSO DISPLAY CONTENT ON CONSOLE
return "search";
}
}
MY REPOSITORY
public interface ClientRepository extends CrudRepository<Client, Integer> {
#Query(value = "select * from client where name LIKE ('%:?%')", nativeQuery = true)
Iterable <Client> search(String search);
}

You can try this query:
#Query(value = "select * from client where name LIKE :search", nativeQuery = true)
Iterable <Client> search(#Param("search") String search);
I suggest you debug your code and run the query separately in SSMS. Then alter your query and finalize the one where you get your desired output.
Your query should have the searched text between %%. Something Like
#Query(value = "select * from client where name LIKE ('%"+ searchedText +"%')", nativeQuery = true)
I hope it helps.
i'm have problem with load page by id. I'm creating simple forum in Spring and when i created topic i got page like this /topic/10 (10 is id topic) and nextly i want to add inscription to this topic so after click button submit should be /inscription/topic/10 (10 is id topic). Now is the problem, when i click button i got Error 405 but when i take this line and write by hand or copy address and paste it again then i got inscription page. Where is problem? Its can be thymeleaf or spring request?
Code is below
#Controller
#RequestMapping("/inscription/")
public class InscriptionController {
private InscriptionService inscriptionService;
private TopicService topicService;
#Autowired
private InscriptionController(InscriptionService inscriptionService, TopicService topicService) {
this.inscriptionService = inscriptionService;
this.topicService = topicService;
}
#GetMapping("topic/{id}")
public String in2(#ModelAttribute("inscription") Inscription inscription, #PathVariable Long id, Model model) {
Topic topic = topicService.findOne(id);
model.addAttribute("inscription", inscription);
return "inscription";
}
Thymeleaf - here when i press button New Message should be go to inscription/topic/id

405 error means "Method Not Allowed". When you click the submit button, your form will perform the POST method, which doesn't have the corresponding mapping in your controller. You should add POST mapping to your controller or change the form method to GET.
I am working on a Spring web project , I have many JSP files and many controllers , but I am not able to grab how this
<form:form action="updateCustomer" autocomplete="true" commandName="customer">
form is automatically mapped to the respective controller in which the updateCustomer is defined. There are other controllers also but how exactly the url updateCustomer goes to respective controller.
The Customer.jsp file is as follows :
<%# page language="java" contentType="text/html; charset=ISO-8859-1"

Now the question is when I click save button the url formed is :
http://localhost:8080/82ism/buyer/updateCustomer
How this happened ? and now when I need a button to some other controller I need to give the whole URL as follows :
${pageContext.request.contextPath}/seller/edit_profile
The project is working all fine I am just trying to understand this concept.
The whole point of spring is so you don't have to worry about that stuff.
jsp's get found cause of the propperty's in application.propperties:
like:
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
For the forms and methods... It's not like it magicly happens.
A form you have to cal by name and methods are eighter mapped to a url or action
like:
#RequestMapping("/")
or
#RequestMapping(method=RequestMethod.POST)
To call the values of a form from the controller you first have to bind them to a entity model with the fields of the form as variables.
The method would look like:
#RequestMapping(method = RequestMethod.POST)
public String processRegister(#ModelAttribute("userForm") User user,
Map<String, Object> model) {
...
return "view";
}
I want to add payments to my clients database but when I add the payments I got this error "GET NOT SUPPORTED" I don't know what's the problem. Can you guys help me?
#Controller
public class PaymentsController {
#Autowired
private UsersService usersService;
#Autowired
private PaymentsService paymentsService;
#RequestMapping(value = "/addPayments", method = RequestMethod.POST)
public String addPayments(HttpServletRequest request, ModelMap map) {
String user = request.getParameter("userId"); // this is the identifier for the user of this payment
String transactName = request.getParameter("transactName");
String paid = request.getParameter("paid");
String unpaid = request.getParameter("unpaid");
String balance = request.getParameter("balance");
String total = request.getParameter("total");
//.... get all other attributes you've passed from the form through request.getParameter("");
//next, check whether or not a user with the userId from the screen exists in the db
Users userObject = usersService.getUsers(user);
//.getUsersByUserId(user);
if (userObject != null) {
// this means that we have a valid user to insert the payment to
UsersPayments payment = new UsersPayments();
payment.setUsers(userObject);
payment.setTransactName(transactName);
payment.setPaid(paid);
payment.setUnpaid(unpaid);
payment.setBalance(balance);
payment.setTotal(total);
//.... set the other properties of UsersPayment object
paymentsService.addPayments(payment);
}
else {
// you have an error right here
}
map.put("paymentsList", paymentsService.getAllPayments());
return "payments";
}

You only seem to have one handler mapping, and it's POST. Add another handler mapping for the same url path with GET. Consider the "POST Redirect GET" pattern as well.
In my web application, I have a home page where the options available to the user are placed in a fixed sidebar in the top of the screen, and each one of this options are opened inside of a tag <div> in this same page.
My problem is: when this content is a form, and I submit it to the server, after the processing, the output page isn't opened in this <div>, but in the entire navigation space. What I want is a way of capture this return and display it in the same <div> it was originated.
the code for my home page is:

To finish, the page "cad_evento.html" used as action for the form above, is handled by method of same name from Controller:
#RequestMapping(value="/cad_evento", method=RequestMethod.POST)
public ModelAndView cadastra_evento(#RequestParam("nome") String nome, #RequestParam("descricao") String descricao, #RequestParam("data_inicial") String data_inicial, #RequestParam("hora_inicial") String hora_inicial, #RequestParam("data_final") String data_final, #RequestParam("hora_final") String hora_final, #RequestParam("duracao") int duracao) {
if(sessao != null)
{
if(sessao.getUsuario().temAutorizacao("cad_evento"))
{
Date d_inicio = new Date(Date.parse(data_inicial));
Date d_final = new Date(Date.parse(data_final));
Time h_inicio = new Time(Time.parse(hora_inicial));
Time h_final = new Time(Time.parse(hora_final));
EventoDAO evento = new EventoDAO(nome, descricao, d_inicio, d_final, h_inicio, h_final, duracao, sessao.getUsuario());
int saida = evento.cadastra();
if(saida == 0)
{
ModelAndView mav = new ModelAndView();
mav.addObject("message", "Erro ao cadastrar o evento");
return mav;
}
else
{
ModelAndView mav = new ModelAndView();
mav.setViewName("/listagem_evento");
return mav;
}
}
else
{
ModelAndView mav = new ModelAndView();
mav.addObject("message", "Usuário sem permissão de acesso");
return mav;
}
}
else
{
ModelAndView mav = new ModelAndView();
mav.setViewName("/usuario_login_page");
return mav;
}
}
Someone have any thoughts about how to do that?
Well, spring mvc just open new page with a content you set in ModelAndView. If you want to load somthing just in some part of page ( in this case ) there pure javascript / jquery ajax is needed. So steps needed here:
Add javascript which will do ajax request to controller
Controller need to return JSON ( #ResponseBody can help you )
You have to do some DOM manipulation using javascript/jquery to put JSON answer to your div.
