특정 게시물만 전체분류에서 노출 안되게 하는 법

def is_duplicate_post(board, subject, category):
    query = f"SELECT * FROM {board} WHERE wr_subject = %s AND category = %s"
    result = db.execute(query, (subject, category))
    return bool(result)

<label>
    <input type="checkbox" name="wr_checkbox" value="1">분류 목록 노출 않함
</label>

def get_posts(board):
    query = f"SELECT * FROM {board} WHERE (category = 'A' OR category = 'B') AND wr_checkbox != 1"
    posts = db.execute(query)
    return posts
