将html链接中的值传递给flask中的my函数

我想将html链接中的值传递给flask中的函数: 警察姓名旁边有一个按钮,如果单击它,我应该获取其id并将其发送到python函数这里是 html代码 :

 <ul class="list-group">
{% for p in policemen %}
 <li class="list-group-item">{{ "  "~ p.rank ~"  "}}
    <div class="col-md-2 text-center"> 

        <a href='/deletepolice/{{p.id}}' class="btn btn-primary btn-lg" > 
    </div> Delete ? 
        </a>
</li> 

{% endfor %}

下面是python函数:

@app.route('/deletepolice/<string:id>', methods=['GET','POST'])
def deletepolice(id):
 # Create cursor
    cur = mysql.connection.cursor()
   # Execute
    cur.execute("DELETE FROM police WHERE id = %s", [id])

# Commit to DB
    mysql.connection.commit()

#Close connection
    cur.close()

    flash('Police man deleted', 'success')

return redirect(url_for('policemen'))
