百里香的隐藏输入值错误

Question

in GET method I'm adding these to the model:

model.addAttribute("team", team);
model.addAttribute("players", team.getPlayers());
model.addAttribute("inviting", new InvitingPlayerToTeam());

And a fragment of view with this model:

<div id="news" th:fragment="playerList">
  <span>Nazwa: </span>
  <span th:text="${team.name}">nazwa teamu</span>
  <br>
  <span th:each="player : ${players}" th:utext="${player.username} + '</br>'">-</span>
  <br><br>
  <form method="POST" th:action="@{/team/invitePlayer}" th:object="${inviting}">
    Nazwa <input type="text" th:field="*{username}">
    <input type="hidden" th:field="*{teamId}" th:value="${team.id}">
    <br>
    <input type="submit" value="Zaproś">
  </form>
</div>

What is wrong? In post method field inviting.username has good value, but inviting.teamId is 0 . Where is the problem?

Answer 1

Just remove th:value="${team.id}" . You do not need to set this value again.

You should set up your form backing bean with the correct values in your controller.

inviting.setTeamId(...)
