Thymeleaf using path variables to th:href

Here's my code, where I'm iterating through:

<tr th:each="category : ${categories}">
     <td th:text="${category.idCategory}"></td>
     <td th:text="${category.name}"></td>
     <td>
         <a th:href="@{'/category/edit/' + ${category.id}}">view</a>
     </td>
</tr>

The URL it points to is supposed to be /category/edit/<id of the category>, but it says it could not parse the expression:

Exception evaluating SpringEL expression: "category.id" (category-list:21)

Hi you can use thymeleaf preprocessing :

<tr th:each="category : ${categories}">
    <td th:text="${category.idCategory}"></td>
    <td th:text="${category.name}"></td>
    <td>
        <a th:href="@{__${category.idCategory}__}">view</a>
    </td>
 </tr>

You can also use ${yourVariable} for exampe <th:href="/category/edit/__${yourVariable}__">View</a>

You can use:

html:

 <html xmlns:th="http://www.thymeleaf.org">

<a th:href="@{'/category/'+ ${item.idCategory}}">View</i></a>

Controller: @PathVariable String parentId

try this one is a very easy method if you are in list of model foreach (var item in Modal) loop

<th:href="/category/edit/@item.idCategory>View</a>"

or

<th:href="/category/edit/@item.idCategory">View</a>

You can use like

My table is bellow like..

<table>
   <thead>
    <tr>
        <th>Details</th>
    </tr>
</thead>
<tbody>
    <tr th:each="user: ${staffList}">
        <td><a th:href="@{'/details-view/'+ ${user.userId}}">Details</a></td>
    </tr>
 </tbody>
</table>

Here is my controller ..

@GetMapping(value = "/details-view/{userId}")
public String details(@PathVariable String userId) { 

    Logger.getLogger(getClass().getName()).info("userId-->" + userId);

 return "user-details";
}

Your code looks syntactically correct, but I think your property doesn't exist to create the URL.

I just tested it, and it works fine for me.

Try using category.idCategory instead of category.id, for example…

  <tr th:each="category : ${categories}">
    <td th:text="${category.idCategory}"></td>
    <td th:text="${category.name}"></td>
    <td>
      <a th:href="@{'/category/edit/' + ${category.idCategory}}">view</a>
    </td>
  </tr>

I think your problem was a typo:

<a th:href="@{'/category/edit/' + ${category.id}}">view</a>

You are using category.id, but in your code is idCategory, as Eddie already pointed out.

This would work for you:

<a th:href="@{'/category/edit/' + ${category.idCategory}}">view</a>

"List" is an object getting from backend and using iterator to display in table

"minAmount" , "MaxAmount" is an object variable "mrr" is an just temporary var to get value and iterate mrr to get data.

<table class="table table-hover">
<tbody>
<tr th:each="mrr,iterStat : ${list}">
        <td th:text="${mrr.id}"></td>
        <td th:text="${mrr.minAmount}"></td>
        <td th:text="${mrr.maxAmount}"></td>
</tr>
</tbody>
</table>

I was trying to go through a list of objects, display them as rows in a table, with each row being a link. This worked for me. Hope it helps.

// CUSTOMER_LIST is a model attribute
<table>
    <th:block th:each="customer : ${CUSTOMER_LIST}">
        <tr>
            <td><a th:href="@{'/main?id=' + ${customer.id}}" th:text="${customer.fullName}" /></td>
        </tr>
    </th:block>
</table>

The right way according to Thymeleaf documention for adding parameters is:

<a th:href="@{/category/edit/{id}(id=${category.idCategory})}">view</a>

A cleaner and easier way to do this

<a href="somepage.html" th:href="@{|/my/url/${variable}|}">A Link</a>

I found this solution in Thymeleaf Documentation on "4.8 Literal substitutions".

I think you can try this:

<a th:href="${'/category/edit/' + {category.id}}">view</a>

Or if you have "idCategory" this:

<a th:href="${'/category/edit/' + {category.idCategory}}">view</a>
