一百三十九：CMS系统之首页帖子列表布局

# 配置ueditor上传文件到七牛
UEDITOR_UPLOAD_TO_QINIU = True  # 设置为True是，视为开始把图片传到七牛储存，本地不储存
UEDITOR_QINIU_ACCESS_KEY = ''
UEDITOR_QINIU_SECRET_KEY = ''
UEDITOR_QINIU_BUCKET_NAME = ''  # 空间
UEDITOR_QINIU_DOMAIN = ''  # 域名

调整模型，加上与用创建户的映射关系

确认两件事，1、post表内的数据为空，2、关联表的字符集和排序规则一致

python manager.py db migrate
python manager.py db upgrade

在首页视图，加上返回帖子的数据

@bp.route('/')
def index():
    banners = BannerModel.query.order_by(BannerModel.priority.desc()).limit(4)  # 只取4条
    boards = BoardModel.query.all()
    posts = PostModel.query.all()
    context = {'banners': banners, 'boards': boards, 'posts': posts}
    return render_template('front/front_index.html', **context)

添加帖子的视图加上指定author_id

添加一篇帖子

添加一些测试数据

@manager.command
def create_post():
    """ 添加帖子测试数据 """
    for x in range(1, 203):
        post = PostModel(title=f'标题{x}', content=f'内容{x}')
        post.board_id = BoardModel.query.first().id
        post.author_id = FrontUser.query.first().id
        db.session.add(post)
        db.session.commit()
    print('测试数据添加完成')

由于用户没有设置头像，所以这里的头像全都是取的logo
