一篇完整的博客

  1. 个人学期总结
  2. 总结Python+Flask+MysqL的web建设技术过程,标准如下:
    1. 即是对自己所学知识的梳理
    2. 也可作为初学入门者的简单教程
    3. 也可作为自己以后复习的向导
    4. 也是一种向外展示能力的途径

        学习管理信息系统这门课程,首先要了解管理信息系统的本质,明确区分信息与数据、信息与知识。对管理信息系统这门课程的理论知识要熟记于心。

        众所周知,管理信息系统是为了适应现代化管理的需要,在管理科学、系统科学、信息科学和计算机科学等学科的基础上形成的一门科学,它研究管理系统中信息处理和决策的整个过程,并探讨计算机的实现方法。它是一个由人、计算机、通信设备等硬件和软件组成的,能进行管理信息的收集、加工、存储、传输、维护和使用的系统。管理信息系统可促使企业向信息化方向发展,使企业处于一个信息灵敏、管理科学、决策准确的良性循环之中,为企业带来更高的经济效益。所以,管理信息系统是企业现代化的重要标志,是企业发展的一条必由之路。

       信息系统在管理各项事务中有着普遍的应用,促进了企业管理工作的提升。管理信息系统是为管理服务的,它的开发和建立使企业摆脱落后的管理方式,实现管理现代化的有效途径。管理信息系统将管理工作统一化、规范化、现代化,极大地提高了管理的效率,使现代化管理形成统一、高效的系统。过去传统的管理方式是以人为主体的人工操作,虽然管理人员投入了大量的时间、精力,然而个人的能力是有限的,所以管理工作难免会出现局限性,或带有个人的主观性和片面性。而管理信息系统使用系统思想建立起来的,以计算机为信息处理手段,以现代化通信设备为基本传输工具,能力管理决策者提供信息服务的人机系统,这无疑是将管理与现代化接轨,以科技提高管理质量的重大举措。管理信息系统将大量复杂的信息处理交给计算机,使人和计算机充分发挥各自的特长,组织一个和谐、有效的系统,为现代化管理带来便捷。

       在现代化管理中,计算机管理信息系统已经成为企业管理不可缺少的帮手,它的广泛应用已经成为管理现代化的重要标志。在企业管理现代化中,组织、方法、控制的现代化离不开管理手段的现代化。随着科学技术的发展,尤其是信息技术和通讯技术的发展,使计算机和网络逐渐应用于现代管理之中。面对越来越多的信息资源和越来越复杂的企业内外部环境,企业有必要建立高效、实用的管理信息系统,为企业管理决策和控制提供保障,这是实现管理现代化的必然趋势。所以我觉得学习管理信息系统是非常必要的,特别是对我们电子商务的学生而言。我觉得平时上课学习是不够的,要更加注重实践操作,并且也要多做练习题,这样有利于更好的了解管理信息系统。

#建立MySQL和app的连接
from flask import Flask, render_template
from flask_sqlalchemy import SQLAlchemy
import config

app = Flask(__name__)
app.config.from_object(config)
db = SQLAlchemy(app)

#创建用户模型
class User(db.Model):
    __tablename__ = 'User'
    id = db.Column(db.Integer, primary_key=TabError, autoincrement=True)
    username = db.Column(db.String(20), nullable=False)
    password = db.Column(db.String(20), nullable=False)

db.create_all(

12、练习对数据库的增删改查。(作业24)

# 创建用户
user=User(username='meow2',password='meow2222',nickname='miao~')
db.session.add(user)
db.session.commit()
#查询
user=User.query.filter(User.username=='meow1').first()
print(user.username,user.password)
# 修改密码
user=User.query.filter(User.username=='meow1').first()
user.password='9999999999999'
db.session.commit()
# 删除
user=User.query.filter(User.username=='meow2').first()
db.session.delete(user)
db.session.commit()

13、写JS文件,onclick函数return true时才提交表单。(作业25)

function fnRegist() {
    var zcoUname = document.getElementById("zcuname")
    var zcoError = document.getElementById("zcerror_box")
    zcoError.innerHTML = "
" if (zcoUname.value.length < 6 || zcoUname.value.length > 12) { zcoError.innerHTML = "用户名为6到12位"; return false } return true }
<form action="{{ url_for('regist') }}" method="post">
......
<button onclick="fnRegist()">立即注册button>

14、用session记住登录的用户名传到页面。(作业26)

@app.route('/login/', methods=['GET', 'POST'])
def login():
    if request.method=='GET':
        return render_template('login.html')
    else:#读取表单数据
        usern = request.form.get('username')
        passw = request.form.get('password')
        user = User.query.filter(User.username == usern,User.password==passw).first()#查找对应的用户名、密码
    if user:
        session['user']=usern
        session.permanent=True
        return redirect(url_for('index'))

    else:
        return u'用户名不存在/密码错误'

15、在模板中做导航。(作业27)

@app.context_processor#上下文处理器定义函数
def mycontext():
    usern=session.get('user')#获取session中保存的值
    if usern:
        return {'username':usern}#返回字典
    else:
        return {}
    {% if username %}
        <li><a href="#">{{ username }}a>li>
        <li><a href="#">注销a>li>
    {% else %}
        <li><a href="{{ url_for('login') }}">登录a>li>
        <li><a href="{{ url_for('regist') }}">立即注册a>li>
    {% endif %}
@app.route('/logout/')#注销功能
def logout():
    session.clear()#清除session中保存的值
    return redirect(url_for('index'))

16、编写并应用登录装饰器,完成发布功能。(作业28)

def loginFrist(func):#参数是函数
    @wraps(func)
    def wrapper(*args, **kwargs):#定义个函数将其返回
        if session.get('user'):
            return func(*args, **kwargs)
        else: #要求登录
            return redirect(url_for('login'))
    return wrapper
@app.route('/question/', methods=['GET', 'POST'])
@loginFrist#应用装饰器,发布前先登录
def question():
    if request.method == 'GET':
        return render_template('question.html')
    else:
        title = request.form.get('title')
        detail = request.form.get('detail')
        author_id = User.query.filter(User.username == session.get('user')).first().id
        question = Question(title=title, detail=detail, author_id=author_id)
        db.session.add(question)
        db.session.commit()#保存到数据库
        return redirect(url_for('index'))#重定向到首页

17、尝试在首页显示问答列表。(作业29)

18、在首页显示全部问答。(作业30)

@app.route('/')
def index():#将数据库查询结果传递到前端页面
    context={
        'questions':Question.query.order_by('-creat_time').all()
    }
    return render_template('index.html',**context)
{% for foo in questions %}#前端页面循环显示整个列表。
                <li  class="list-group-item">
                    <span class="glyphicon glyphicon-leaf" aria-hidden="true">span>
                    <a href="#">{{ foo.author.username }}a><br>
                    <a href="{{ url_for('detail',question_id=foo.id) }}" class="title">{{ foo.title }}a>
                    <span class="badge">{{ foo.creat_time }}span>
                    <p class="detail">{{ foo.detail }}p>

                li>
            {% endfor %}

19、首页文章标题链接详情页。(作业31)

@app.route('/detail/')#视图函数,带id参数
def detail(question_id):#查询对应的文章详情
    quest=Question.query.filter(Question.id==question_id).first()
    return render_template('detail.html',quest=quest)#返回详情
<a href="{{ url_for('detail',question_id=foo.id) }}" class="title">{{ foo.title }}a>#首页文章title链接详情

20、评论功能的实现。(作业32)

@app.route('/comment/', methods=['POST'])
@loginFrist#评论前登录
def comment():#读取页面数据
    comment_detail = request.form.get('new_comment')
    quest_id = request.form.get('question_id')
    author_id = User.query.filter(User.username == session.get('user')).first().id
    comment = Comment(detail=comment_detail, author_id=author_id, question_id=quest_id, )
    db.session.add(comment)#保存到数据库
    db.session.commit()
    return redirect(url_for('detail', question_id=quest_id))
<input type="hidden" name="question_id" value="{{ quest.id }}">#获取前端的"question_id" 

21、在详情页显示该文章所有评论。(作业33)

                    {% for foo in quest.comments %}#循环显示所有评论
                        <li class="list-group-item">
                            <a href="#">{{ foo.author.username }} a>
                            <span class="badge">{{ foo.creat_time }}span>
                            <p>{{ foo.detail }}p>
                        li>
                    {% endfor %}

22、个人中心。(作业33、34、35)

@loginFrist
def usercenter(user_id,tag):
    user=User.query.filter(User.id==user_id).first()
    context={
        'user':user,
        'nickname':user.nickname,
        'comments':user.comments,
        'questions':user.question,
    }
    if tag == '1':#三个标签页
        return render_template('usercenterQ.html', **context)
    elif tag == '2':
        return render_template('usercenterC.html', **context)
    elif tag == '3':
        return render_template('usercenterI.html', **context)
