Flask实战第64天：帖子加精和取消加精功能完成

帖子加精和取消加精是在cms后台来设置的

后台逻辑

首页个帖子加精设计个模型表，编辑apps.models.py

class HighlightPostModel(db.Model):
    __tablename__ = 'highlight_post'
    id = db.Column(db.Integer,primary_key=True,autoincrement=True)
    post_id = db.Column(db.Integer,db.ForeignKey("post.id"))
    create_time = db.Column(db.DateTime,default=datetime.now)

    post = db.relationship("PostModel",backref="highlight")

同步表到数据库

python manage.py db migrate
python manage.py db upgrade

视图函数，编辑cms.views.py

from apps.models import HighlightPostModel, PostModel
...

@bp.route('/posts/')
@login_required
@permission_required(CMSPersmission.POSTER)
def posts():
    post_list = PostModel.query.all()
    return render_template('cms/cms_posts.html', posts=post_list)


@bp.route('/hpost/',methods=['POST'])
@login_required
@permission_required(CMSPersmission.POSTER)
def hpost():
    post_id = request.form.get("post_id")
    if not post_id:
        return xjson.json_param_error('请传入帖子id！')
    post = PostModel.query.get(post_id)
    if not post:
        return xjson.json_param_error("没有这篇帖子！")

    highlight = HighlightPostModel()
    highlight.post = post
    db.session.add(highlight)
    db.session.commit()
    return xjson.json_success()


@bp.route('/uhpost/',methods=['POST'])
@login_required
@permission_required(CMSPersmission.POSTER)
def uhpost():
    post_id = request.form.get("post_id")
    if not post_id:
        return xjson.json_param_error('请传入帖子id！')
    post = PostModel.query.get(post_id)
    if not post:
        return xjson.json_param_error("没有这篇帖子！")

    highlight = HighlightPostModel.query.filter_by(post_id=post_id).first()
    db.session.delete(highlight)
    db.session.commit()
    return xjson.json_success()

前端逻辑完成

                    setTimeout(function () {
                        window.location.reload();
                    },500);

                }
            }
        });
    });
});

前台页面，要加精的帖子加个标签,编辑front_index.html
