单击按钮时，如何在 jinja 模板中运行 Python 代码？

Question

<html>
    <head>

    </head>
    <body>
        {% for post in posts %}
            {% if loop.changed(current_post) %}
            <div>
                <a href="{{ url_for('read', post_name=post.post_name) }}">
                  <img src="{{ url_for('static', filename='images/'+post.title) }}" alt="">
                </a>
              </div>
              {% if current_user.is_moderator %}
                <div>
                  <button>DELETE POST</button>
                </div>
              {% endif %}
              <!-- <div>{{ current_post }}</div>
                <div>{{ current_post }}</div> -->
            {% else %}
                {% set current_post = post.post_name %}
                <div></div>
            {% endif %}
        {% endfor %}
    </body>
</html>

Basically, I want to delete the post whose post_name value is stored inside the current_post variable when the DELETE POST button is clicked.基本上，我想在单击 DELETE POST 按钮时删除其 post_name 值存储在 current_post 变量中的帖子。 For that I would want to execute the following Python code:为此，我想执行以下 Python 代码：

Image.query.filter_by(post_name=current_post).delete()

How can I run this code when someone clicks on the DELETE POST button?当有人单击 DELETE POST 按钮时，如何运行此代码？

Answer 1

Delete button should be linked to a flask route that deletes the a post given a post_name.删除按钮应链接到烧瓶路线，该路线删除给定 post_name 的帖子。

example:例子：

<a href="{{ url_for('delete_post', post_name=current_post.post_name) }}">
    DELETE POST
</a>
