大型ERP(企业资源计划)系统的开发是一个复杂的过程,涉及到多个模块和组件,由于篇幅限制,我无法提供完整的源码,但我可以为您提供一个简要的概述和一些关键模块的示例代码。
1、用户管理模块:负责用户的注册、登录、权限分配等功能。
class User:
def __init__(self, username, password, role):
self.username = username
self.password = password
self.role = role
class UserManager:
def __init__(self):
self.users = []
def register(self, username, password, role):
user = User(username, password, role)
self.users.append(user)
def login(self, username, password):
for user in self.users:
if user.username == username and user.password == password:
return True
return False
2、产品管理模块:负责产品的添加、编辑、删除等功能。
class Product:
def __init__(self, id, name, price, stock):
self.id = id
self.name = name
self.price = price
self.stock = stock
class ProductManager:
def __init__(self):
self.products = []
def add_product(self, id, name, price, stock):
product = Product(id, name, price, stock)
self.products.append(product)
def edit_product(self, id, name=None, price=None, stock=None):
for product in self.products:
if product.id == id:
if name:
product.name = name
if price:
product.price = price
if stock:
product.stock = stock
break
def delete_product(self, id):
self.products = [product for product in self.products if product.id != id]
3、订单管理模块:负责订单的创建、编辑、删除等功能。
class Order:
def __init__(self, id, customer, products):
self.id = id
self.customer = customer
self.products = products
class OrderManager:
def __init__(self):
self.orders = []
def create_order(self, id, customer, products):
order = Order(id, customer, products)
self.orders.append(order)
def edit_order(self, id, customer=None, products=None):
for order in self.orders:
if order.id == id:
if customer:
order.customer = customer
if products:
order.products = products
break
def delete_order(self, id):
self.orders = [order for order in self.orders if order.id != id]
这只是一个简单的示例,实际的ERP系统会更加复杂,包括库存管理、财务管理、报表生成等多个模块,您可以根据实际需求进行扩展和完善。
