Computer graduation design Python+django online food ordering system (source code + system + mysql database + Lw document)

Project Introduction

This paper mainly discusses how to use python language to develop an online food ordering system. This system will carry out the work at each stage strictly according to the software development process, using B/S architecture and object-oriented programming ideas for project development.In the introduction, the author will discuss the current background of the online ordering system and the purpose of system development. The subsequent chapters will analyze and design the system at each stage in strict accordance with the software development process.
The main users of the online ordering system are divided into administrators, merchants and users. The functions include administrators: home page, personal center, personal information, food type management, forum management, system management, business management, food information management, Complaint and suggestion management, user management, order information management, evaluation information management and so on.Merchant management: personal center, personal information, food information, management of complaints and suggestions, management of order information, evaluation information and other functions.User management: personal center, personal information, management of complaints and suggestions, management of order information, evaluation information, my favorites, etc.Because the functional modules of this website are designed comprehensively, the whole process of online ordering system can be realized.

System screenshot

Users enter the front desk to register, fill in the user name, user name, password, contact number, etc. to register.After success, you can log in to the front desk.After the account password is successfully entered, a successful login message will be displayed

Users can view the details page of the food in the food information at the front desk, and can place orders, pay, save and other operations as shown in the figure


The administrator enters the personal account number and password to log in to the system. At this time, the database of the system will search for relevant information. If the account number, password and verification code we enter are incorrect, the database will prompt an incorrect information prompt.At the same time, the administrator will be prompted to re-enter his account, password, and verification code, until the account and password are successfully entered, and a successful login message will be displayed.The effect diagram of the website administrator's login is shown in the figure
The administrator manages the food informationPerform operations such as uploading, deleting, modifying, and checking.The program rendering is as follows
