我正在尝试创建一个网站，在一个表格上跟踪喜欢（戳），每次点击戳按钮都会将戳数附加 1。同时我希望用户能够知道谁戳了他们以及戳了多少用户戳他们的次数。

这是我的代码。

html:

<!DOCTYPE html>
<html>
    <head>
        <link rel="stylesheet" type="text/css" href="style.css">
        <a href="/logout">Logout</a>
        <form action="/home" method="GET">
            {% csrf_token %}
        <h1>Welcome! {{request.session.name}}
            People have poked you
            {{%for stick in pokes%}}
            {{stick.first_name}}
            {{%endfor%}}
        </h1>
    </form>
    </head>
    <body>
        <p>People who you may want to poke</p>
        <table>
            <thead><th>Name</th><th>Alias</th><th>Email Address</th><th>Poke History</th><th>Action</th></thead>
            {%for stick in poke%}
            <tr><td>{{stick.first_name}}{{stick.last_name}}</td> <td>{{stick.first_name}}</td> <td>{{stick.email}}</td> <td>{{stick.}}</td> <td><form action="/poke" method="POST"><button>Poke</button></form></td></tr>
            {%endfor%}
        </table>
    </body>
