本周作业:综合应用面向对象
角色:学校、学员、课程、讲师
要求:
1. 创建北京、上海 2 所学校
2. 创建linux , python , go 3个课程 , linux\py 在北京开, go 在上海开
3. 课程包含,周期,价格,通过学校创建课程
4. 通过学校创建课程, 课程关联学校
4.1 创建学员时,选择学校,关联课程
4.2 创建讲师角色
5. 提供三个角色接口
5.1 学员视图, 可以注册, 交学费, 选择课程,
5.2 讲师视图, 讲师可管理自己的课程, 上课时选择班级, 查看课程学员列表,修改所管理的学员的成绩
5.3 管理视图,创建讲师, 创建班级,创建课程
6. 上面的操作产生的数据都通过pickle序列化保存到文件里
1. 需求分析
- 管理员功能
- 注册
- 登录
- 创建学校
- 创建课程(先选择校区. 再创建课程, 并将课程绑定到选择的校区)
- 创建讲师(老师名,老师密码默认密码为123)
- 学生功能
- 注册
- 登录
- 选择校区
- 选择课程(先选择校区, 再选择校区中的某一门课程)
- 学生选择课程, 学生可以修多门课程, 选择课程对选择的课程进行标识.
- {"课程": False, "课程1": False}. 只有在交费以后学生才能看到交费后的课程成绩.
- 查看余额
- 充值金额
- 交学费
- 交费以后修改交费课程对应的课程标识
- {"课程": True}
- 交费以后学生当前校区下的课程添加该学生(某一校区下的某一门课程包含多个来选择的学生 )
- 查看成绩
- 老师功能
- 登录
- 查看授课课程
- 选择授课课程(先选择校区, 再选择校区下开设的课程)
- 查看授课课程下学生(先查看授课课程, 并选择相应课程, 拿到课程下对应的学生)
- 修改授课课程下学生分数(先查看授课课程, 并选择相应课程, 拿到课程下对应的学生, 再进行修改分数)
2. 程序的架构设计
- ATM + 购物车
- 用户视图层: 与用户交互
- 逻辑接口层: 核型的业务逻辑
- 数据处理层: 针对数据的增删改查
- json格式的数据
- '{"key": "value"}' 类型的数据
- python
- 字典格式: --> {'key': 'value'}
- 选课系统
- 三层架构
- 用户视图层:
- 与用户交互
- core
- main.py 主视图
- admin.py
admin_view
- teacher.py
teacher_view
- student.py
student.view
- 逻辑接口层:
- 核心的业务逻辑的处理
- interface
- admin_interface.py
- teacher_interface.py
- student_interface.py
- 数据处理层:
- 争对数据的 增 删 查 改
- models.py
- 用于存放所有类, 管理所有类
- Base
- save(self):
db_handler.save(self)
@classmethod
- select(cls, user):
return db_handler.select(cls, user)
- Admin(Base)
- __init__(self, admin_name, password):
self.user = admin_name
self.password = password
self.save()
@classmethod
- create_school(addr):
School(addr)
@classmethod
- create_course(school_obj, course_name, course_period, course_price):
Course(course_name, course_period, course_price)
school_obj.course_list.append(course_name)
school_obj.save()
@classmethod
- create_teacher(teacher_name, password):
Teacher(teacher_name, password)
- School(Base)
- __init__(self, addr):
self.user = addr
self.course_list = []
self.save()
- Course(Base)
- __init__(self, course_name, course_period, course_price):
self.user = course_name
self.period = course_period
self.price = course_price
self.student_list = []
self.save()
- Student(Base)
- __init__(self, student_name, password):
self.user = student_name
self.password = password
self.balance = 0
self.course_dic = {}
self.score = {}
self.save()
- Teacher(Base)
- __init__(self, teacher_name, password):
self.user = teacher_name
self.password = password
self.course_list = []
self.save()
- db_handler.py
- save(self): # 保存对象
- 拼接文件夹, 获取对象的类名充当文件夹管理文件
class_name = obj.__class__.__name__
- 再拼接文件, 然后把对象通过pickle序列化到文件中
- select(cls, user): # 获取对象
- 拼接文件夹, 获取类名充当文件夹管理文件
class_name = cls.__name__
- 再拼接文件, 然后把通过pickle反序列文件取出文件中的对象
- ATM + 购物车
- 存放json格式的数据
- python数据类型 <-> json <-> 文件
- 选课系统
- pickle保存对象
- 对象 <-> pickle <-> 文件
3. 分任务开发
4. 测试
5. 上线运行
二. 流程图

二. 项目架构
course_selection_system/
├── start.py (提示: 这里的start.py有两种放置的方法,一种是放到bin目录下。一种放到course_selection_system这个文件夹下面。放到course_selection_system这个文件夹下面。好处是不需要在当前文件中处理添加环境变量的问题, 也就是当我们调用别的目录下的模块功能的时候不会发生找不到到模块路径的问题。)
