用wxpython实现的简单图书管理系统，可以实现增加图书，删除图书，修改图书，查看图书。后台数据库为mysql数据库，采用的pymysql连接数据库。系统界面如下：
代码如下：
1.书本类代码
#author = liuwei date = 2017-06-02 from datetime import * #导入日期模块 __metaclass__ = type class Book: '''一个书本信息类，包括书本名字，作者名字和书本简单信息''' def __init__(self, bookName = "", author = "", content = ""): self.bookName = bookName #书本名字 self.author = author #作者名字 self.content = content #书本信息 self.add_date = date.today() #书本添加日期 def setBookName(self, name): self.bookName = name def getBookName(self): return self.bookName def setAuthor(self, author): self.author = author def getAuthor(self): return self.author def setContent(self, content): self.content = content def getContent(self): return self.content def getAddDate(self): return self.add_date if __name__ == "__main__": mybook = Book() print(mybook.date)
2.数据库操作类代码
#author = liuwei date = 2017-06-02
#数据库帮助类
import pymysql
from book import *
__metaclass__ = type
class DBHelper:
def getCon(self):
'''获取操作数据库的curcor即游标，首先的建立连接，需要服务器地址，端口号，用户名，密码和数据库名'''
#为了能用中文，得加上编码方式
conn = pymysql.connect(host = "localhost", port = 3306, user = "root", password = "201392260", db = "library", charset = "utf8")
return conn
def insertBook(self, book):
'''向数据库中book表插入书本信息，book为Book类对象，包含书本基本信息'''
sql = "insert into book(name, author, content, add_date) values(%s, %s, %s, %s)"
conn = self.getCon();
if conn ==None:
return
cursor = conn.cursor()
cursor.execute(sql, (book.getBookName(), book.getAuthor(), book.getContent(), book.getAddDate()))
conn.commit()
cursor.close()
conn.close()
new_id = cursor.lastrowid
print("新插入键值id为:", new_id)
return new_id
def getAllBook(self):
'''返回数据库中，book表中所有的书本信息'''
sql = "select *from book"
conn = self.getCon()
if conn == None:
return
cursor = conn.cursor()
rownum = cursor.execute(sql) #执行并返回找到的行数
#获取查询结果
rows = cursor.fetchall()
list = []
for item in rows:
bitem = (item[0], item[1], str(item[4]))
list.append(bitem)
conn.commit()
cursor.close()
conn.close()
return list
def getBookById(self, bookid):
'''根据书本id值来寻找书本信息'''
sql = "select book.name, book.author, book.content from book where id=%s"
conn = self.getCon()
if conn == None:
return
cursor = conn.cursor()
cursor.execute(sql, (bookid, )) #参数以元组形式给出
row = cursor.fetchone() #取到第一个结果
conn.commit()
cursor.close()
conn.close()
return row #返回该书本信息
def saveUpdate(self, bookid, book):
'''用book对象来修改id为bookid的书本信息'''
sql = "update book set book.name=%s, book.author=%s, book.content=%s where book.id=%s"
conn = self.getCon()
if conn == None:
return
cursor = conn.cursor()
cursor.execute(sql, (book.getBookName(), book.getAuthor(), book.getContent(), bookid))
conn.commit()
cursor.close()
conn.close()
def deleteBook(self, bookid):
'''根据书本id来删除书籍'''
sql = "delete from book where book.id = %s"
conn = self.getCon()
if conn == None:
return
cursor = conn.cursor()
cursor.execute(sql, (bookid, ))
conn.commit()
cursor.close()
conn.close()
if __name__ == '__main__':
db = DBHelper()
#book = Book("秦腔", "贾凹平", "讲的是大西北夏家和白家的事情，由引生口述。")
#db.insertBook(book)
list = db.getAllBook()
for item in list:
print(item)
