Bootstrap

基于python+mysql的可视化图书管理系统(文末附源码)

该项目主要功能,图书的增删查改,借阅证的增、删;借阅证用于结借书管理;借阅证分为老师和学生,numbers为借阅状态:

项目使用mysql数据库,表为3张:

先看运行主界面及功能:

 主页面实现代码:

initwin(): #主窗口
    def __init__(self,master):
        global im
        global image
        self.master=master
        self.master.config(bg='Magenta')
        self.initwin=tk.Frame(self.master,)
        self.initwin.pack()
        self.canvas = tk.Canvas(self.initwin,  
        width = 1000,      
        height = 700,     
        bg = 'green')      
        
        image=Image.open('bg.jpg')
        im=ImageTk.PhotoImage(image)

        self.canvas.create_image(0,0,anchor='nw',image = im)      # 使用create_image将图片添加到Canvas组件中  

        self.canvas.pack()         # 将Canvas添加到主窗口
        btn_add=ttk.Button(self.initwin,text="图书入库或修改信息",command=self.add)
        btn_query=ttk.Button(self.initwin,text="查询图书信息",command=self.query)
        btn_card=ttk.Button(self.initwin,text="借书证管理",command=self.card)
        btn_borrow=ttk.Button(self.initwin,text="借书",command=self.borrow)
        btn_return=ttk.Button(self.initwin,text="还书",command=self.returnbook)#return是保留字。。。

        self.canvas.create_window(100,50,width=200,height=40,window=btn_add)
        self.canvas.create_window(100,100,width=200,height=40,window=btn_query)
        self.canvas.create_window(100,250,width=200,height=40,window=btn_card)
        self.canvas.create_window(100,150,width=200,height=40,window=btn_borrow)
        self.canvas.create_window(100,200,width=200,height=40,window=btn_return)

        self.title=tk.Label(self.initwin,text="图书管理系统",font=("宋体",30))
        self.author=tk.Label(self.initwin,text="源代码+QQ:3125841747",font=("宋体",24))
        self.canvas.create_window(400,150,anchor="nw",width=300,height=70,window=self.title)
        self.canvas.create_window(400,350,anchor="nw",window=self.author)

    def add(self,): #add窗口,实现的功能:选择批量入库或者单本入库,添加或是修改
        self.initwin.destroy()
        addwin(self.master)
    def query(self):
        self.initwin.destroy()
        querywin(self.master)
    def card(self):
        self.initwin.destroy()
        cardwin(self.master)
    def borrow(self):
        self.initwin.destroy()
        borrowwin(self.master)
    def returnbook(self):
        self.initwin.destroy()
        returnwin(self.master)

图书入库:分为单本入库和读取记事本批量入库:

单本入库:实现对图书的增、改:

 

批量入库成功后,会在文件夹中生成日志文件:

入库图书代码实现:

addwin():
    def __init__(self,master):
        global im
        global image
        self.master=master
        self.master.config(bg='GhostWhite')
        self.str="此处输出状态信息"
        self.addwin=tk.Frame(self.master,)
        self.addwin.pack()
        self.canvas = tk.Canvas(self.addwin,  
        width = 1000,      
        height = 700,     
        bg = 'white')      
        
        image=Image.open('bg.jpg')
        im=ImageTk.PhotoImage(image)

        self.canvas.create_image(0,0,anchor='nw',image = im)      # 使用create_image将图片添加到Canvas组件中  

        self.canvas.pack()         # 将Canvas添加到窗口
        self.btn_back=ttk.Button(self.addwin,text="返回主菜单",command=self.back)
        #btn_back.pack()
        self.canvas.create_window(100,50,width=200,height=40,window=self.btn_back)

        self.mode=tk.IntVar() #选择入库模式(单本或者批量)

        self.style_radio=ttk.Style()
        self.style_radio.configure("radio.TRadiobutton",font=("微软雅黑",12),background="Aqua")

        self.r1=ttk.Radiobutton(self.addwin,text="单本入库(或修改信息)",variable=self.mode,value=1,command=self.display1,style="radio.TRadiobutton")
        self.r2=ttk.Radiobutton(self.addwin,text="批量入库",variable=self.mode,value=2,command=self.display2,style="radio.TRadiobutton")
        self.canvas.create_window(400,50,window=self.r1)
        self.canvas.create_window(400,100,window=self.r2)

        self.style_label=ttk.Style()
        self.style_label.configure("label.TLabel",font=("微软雅黑",14))
        self.s_title=ttk.Label(self.addwin,text="状态栏",style="label.TLabel", width=30,anchor="center")
        self.state=tk.Message(self.addwin,text=self.str,width=300,font=("微软雅黑",12))
        self.canvas.create_window(800,100,height=50,window=self.s_title)
        self.canvas.create_window(650,150,anchor="nw",width=300,window=self.state)
        self.flag1=0#标记“批量入库”的控件是否存在的flag
        self.flag2=0#标记“单本入库”的控件是否存在的flag
        self.cflag=0#change flag,用来区分是添加一本书还是修改书的信息.为1时代表修改

查询图书可以分为:类别、书名、出版社、年份、作者、价格这几种进行查询:

 按类别查询:

按书名查询:

 按出版社查询:

 其他功能不一一演示,​​​​​​​

查询图书的代码:

ef show(self,result):
        #美观方面的问题还需要改进。。。现在先大体实现功能
        #重构此部分,由label改为ttk的Treeview
        self.query_list=ttk.Treeview(self.querywin,columns=["书号","类别","书名","出版社","年份","作者","价格","库存数"],show="headings")#show设为headings可以隐藏首列

        self.canvas.create_window(960,250,height=300,anchor="nw",window=self.query_bar)
        self.btn_list=ttk.Button(self.querywin,text="返回",command=self.destroy_search)
        self.canvas.create_window(480,580,height=30,width=50,window=self.btn_list)

借书需要有借阅证,借阅证添加操作:

拥有借阅的证号,才可以借书:

 还书 :​​​​​​​

  借书代码实现如下:
