- 次更新了login表中用户的记录
- 可以对login表进行搜索吗?🤔
- 在show_data.html中
- 添加如下代码
<form id="search" method="POST" action="/user/search">
<input id="s_usr" name="s_usr" type="input">
<input type="submit" value="search">
</form>
- 尝试提交
- 可以提交表单数据
- 准备编辑/user/search对应的处理函数
@app_user.route("/user/search", methods=['POST', 'GET'])
def search():
current_user = session["current_user"]
username = request.form.get("s_usr")
if current_user != "admin":
return "you cannot update user" + username
username_pattern = "%" + username + "%"
with pool.connection() as conn:
with conn.cursor() as cur:
try:
sql = "SELECT * FROM login WHERE username LIKE %s AND username != 'admin'"
t = (username_pattern,)
cur.execute(sql,t)
records = cur.fetchall()
cur.close()
conn.close()
except Exception:
print(traceback.print_exc())
cur.close()
conn.close()
return username + " already exists"
else:
return render_template("user_manager.html", l = records,current_user = current_user, s_user = username)
- 处理之后
- 能否让 文本框
- 保留上次搜索的内容
- 能否让 文本框
- /templates/show_data.html
<form id="search" method="POST" action="/user/search">
<input id="s_usr" name="s_usr" type="input" value="{{ s_user}}">
<input type="submit" value="search">
</form>
- 这次 完成了
- 对于用户名的搜索
- 可以对搜索结果进行排序吗?🤔
- 下次再说!
