GreaterWMS--Open Source Warehouse Management System

中文文档

Production Introduce:

Fully open source warehouse management system follows Apache License 2.0 and front-back stage decoupling method. API uses restful protocol to facilitate for add-on functions development. The html & js code is constructed with quasar(base on Vue.js v2.6.0+). According to API, it can support business models such as multi warehouse, wave shipment, combined picking and milk-run and so on.

Our Original Intention:

I have 15 years old experience focus on supply chain . I find that in this professional field . No freedom customize software can support our business deeply . Any software are closed-source and hardly to customize or dynamic with our suppliers & customers . So I design GreaterWMS , in order to give business highest freedom way to support trade development .

  • Our Vision: If you work in a non IT industry and you love your industry, please using technology to change it.

Development Environment:

  • Python Version 3.9.5 +

  • Django Version 3.1.12 +(This version of Django only supports asynchronous real-time communication)

  • Django-rest-framework Version 3.12.2 + (Highest versions of Django-rest-framework are more compatible with Django3)

  • Django-silk Version 4.1.0 (If you are deploying production, please turn off silk, which is only used for debugging API interface speed, which may leak users' information)

  • Quasar Version 1.7.2 + (You can view the official website of quasar to edit the webside code of greater WMS: Quasar)

  • Vue Version 2.6.0 +（Try not to use vue3, because the development environment does not use vue3, I don't know what will happened）

  • API，Follow RESTful

Build Command:

  • Git Clone:
git clone https://github.com/Singosgu/GreaterWMS.git
  • Install Python Library:
pip install -r requirements.txt

Atention: Installation requires Twisted library, this library sometimes cannot be installed, you need to download it and install it locally

pip install Twisted{Version Name Which You Download}

Atention: Local installation needs to pay attention to the path

  • Makemigrations the Database:
python manage.py makemigrations
  • Migrate Database:
python manage.py migrate

Create a database. Django uses sqlite3 as the default database. If you need other database, please configure DATABASE in greaterwms/settings.py

Run Development Server:

  • Dev Run：
daphne -p 8008 greaterwms.asgi:application

Run Production Server:

  • supervisor Daemon:
pip install supervisor

Use supervisor to guard the Django process, and then use Nginx as a reverse proxy. As for supervisors, there are many tutorials, so I won’t explain them here.

  • Nginx Support:

It is recommended to use Nginx for deployment. You need to specify the WebSocket link when deploying. If you do not specify it, the real-time communication function will report an error.

Also need to modify ws_url in templates/dist/spa/statics/baseurl.js

## Example changes before
const baseurl = 'http://127.0.0.1:8008/'
const wsurl = 'ws://127.0.0.1:8008/'

## Example changes after
const baseurl = 'https://Your Production Server/'
const wsurl = 'wss://Your Production Server/websocket/'

If the server has SSL enabled, please use https and wss, if SSL is not enabled, use http and ws

The front-end code needs to be rebuilt after modification

Development Guide:

Baseurl

  • It is the basic URL for initiating the request. If it is for local debugging, the default is http://127.0.0.1:8008/. If it is deployed on the server, you need to change it to your website access URL

  • The modification method is to modify axios_request.js. Attention: The modification of websocket has been mentioned

Django-Silk

  • Django-Silk is a debugging tool during development. It can count the response speed of each interface. If you need to deploy to a production environment, please delete the Django-silk related configuration, because there is a risk of leaking user information, or directly modify the Django-silk library , So that users can only see their request data

Database Storage

  • Data migration and other issues are considered during database design, so only the user_id in users and the user_id that comes with Django are foreign keys, and all the other fields do not use foreign keys, which is convenient for data backup and database migration.

    • The database is a 4-stage design
    1. Verify data user ownership
    2. Verify data security
    3. Verify that the data can be stored in the database
    4. Save it in the database and return Response

About Data Request

  • The token value needs to be added to all request headers. This value is the unique identifier OPENID of the user’s data
  • All data transmission needs to set content-type to application/json

OPENID

  • OPENID is the unique identifier of registered user data. When the administrator registers directly, there will be developer=1 as the administrator ID.
  • You can do custom secondary development based on the developer label

APPID

  • APPID is the unique identifier of the user data group
  • If you need multi company operation or multi warehouse operation, you can make unified link through appid to realize multi company and multi warehouse operation

User Jurisdiction

  • There are not too many restrictions on user authorization. Please limit the secondary development according to your own business needs

Business Process:

Administrator

  • Click Register, you can register as an administrator account, so as to realize the initialization program settings
  • After registration, you will get two IDs and one developer label. openid is the unique ID of the user data group. All data under this openid is bound through openid. Appid is the unique ID of the user group data. Multi company and multi warehouse functions are realized through appid. The developer ID is a Boolean value, and true represents an administrator account
  • There are two way for user login:
    1. Login directly with openid and staff name
    2. Administrator login with account and password
  • After login, the web will localstorage login information
  • you can view the openid of user data group by view my openid
  • If multi company and multi warehouse operation is required, pay attention to change openid
  • More administrator authrization, please develop by yourself

Staff

  • After registering as an administrator, create a new staff first
  • Staff has two fields, staff_ Name (for employee login), staff_ Type (employee type to control employee permissions)

At this time, the ASN information can no longer be modified
    2. ASN status = 2, it is developed to queue up for the arrival of drivers. If we have many drivers arriving, it can be made into a queuing system. At the same time, it can also let the purchase and sales see the arrival information, reduce unnecessary email and telephone communication. Click finish loading to confirm that the goods have been unloaded, and Asn status will be updated to 3, The goods information will appear in sorting, and the ASN status indicates that the goods have been unloaded to the warehouse and are waiting for sorting
    3. ASN status = 3, goods sorting is a necessary process. Without goods sorting, goods cannot be put on shelves. The principle of putting on shelves is to arrange the goods and put them on the corresponding warehouse location. Click confirm sorted, and Asn status will be updated to 4, that is, confirm the sorting and wait for loading
    4. At this time, when you move the sorted page, the goods details that need to be put on the shelves will appear. Click move to bin to finish the listing.

    2. DN Status = 2, This is the process when an order is confirmed and waiting to generate a picking list. You can click order release of a single order to generate a picking list of an order. You can also click release all order to generate a picking list of all orders. If all orders are released, the inventory will be matched according to the time sequence. When the inventory is insufficient, back will be generated In this process, the DN order number will change. For example, multiple orders of a customer will be unified into one order for picking. If the customer's order cannot be satisfied, the unsatisfied part will be generated as a shortage order. If the shortage order is not met by the matched inventory, no new order will be generated. Dn The status will be updated to 3, that is, in the process of waiting for picking, the status will be 2 when both the confirmed order and the shortage order are in the same status
    3. DN Status = 3,Direct picking, this function will appear in beta5 update
    4. DN Status = 4, Delivery handover, this function will appear in beta6 update
    5. DN Status = 5, Customer receiving, this function will appear in beta7 update
