如何在 Vue js 中的 v-for 循环中使用 v-model

这是我在这里的第一个问题，我真的很绝望，希望你能帮助我。

我正在尝试使用 vuejs 构建像 Facebook 一样的帖子/评论/回复系统，在使用 Axios 获取数据库中的数据（使用 Laravel API）后，我使用 v-for 循环所有帖子/评论/回复，这里的问题是，当我输入我的输入时，我将 v-model 附加到 v-for 循环内的表单中的问题出现在此处循环的所有其他输入中，这是为了更好地理解->重复输入的图像,

        <div class="panel panel-white post panel-shadow" v-for="(post) in posts" >
            <div class="post-heading">
                <div class="pull-left image">
                    <img src="https://bootdey.com/img/Content/user_1.jpg" class="img-circle avatar" alt="user profile image">
                </div>
                <div class="pull-left meta">
                    <div class="title h5">
                        <a href="#"><b>{{post.user.name}}  </b></a>

                        made a post.
                    </div>
                    <h6 class="text-muted time">(number) minute ago</h6>
