Python django-7 git and project

• The use of Git, mainly includes:
  • Commands for the Local warehouse
  • Commands for remote warehouses
• Project requirements, page, model class design, and page usage

About Git

• Git is currently the world's most advanced distributed version control system
• Installation

sudo apt-get install git

• After the installation is successful, run the following command

git

Remote Warehouse

• Git is a distributed version control system, and the same git repository can be distributed across different machines. First find a computer to act as the role of the server, 24 hours a day, everyone else from the "server" to clone a copy to their own computer, and each to push their own submissions to the server warehouse, but also from the server warehouse to pull someone else's submission. You can build this server yourself, or you can use the GitHub website

Create a GitHub account

• The transfer between the local git repository and the GitHub repository is encrypted via SSH
• Step1: Create SSH Key for project

ssh-keygen -t rsa -C "[email protected]"

• After creation, find the. SSH directory in the user's home directory, there are Id_rsa and id_rsa.pub two files, these two are SSH key key pair, Id_rsa is the private key, can not be leaked out, Id_rsa.pub is the public key, you can safely tell anyone
• step2:* Login to GitHub registration or login account, open the "Settings" SSH Keys page, then, click "New ssh Key", fill in any title, in the Key text box paste id_rsa.pub file content, click "Add Key", You should see the key already added

Create a remote Library

• Login to GitHub
• In the upper right corner, find the "new Repository" button to create a new warehouse

Cloning from a remote library

• Clone a project on GitHub to a local copy

git clone [email protected]:账号名/项目名.git

Interacting with remote libraries

• Get to local from remote library

git pull

• The remote library will be submitted locally

git push origin master

• Tip: You need to get it before each commit, resolve the conflict and resubmit it again

Local Warehouse Create local warehouse

• Create an empty directory

mkdir test7cd test7

• The directory structure diagram is as follows:

• Create a local warehouse under the directory

git init

• After successful creation, the directory structure is as follows:

• Repository is a directory, all the files in this directory can be managed by git, each file modification, deletion, git can track, so that any time can track history, or at some point in the future can "restore"

File Management

• The local warehouse is divided into three parts: work area, staging area, warehouse area, where staging area, warehouse area is the repository part
• Three sections of operations and commands such as

Work area and staging area

• Open a directory with the IDE, create a project, add files to staging area

git add 文件1 文件2 ...git add 目录

• Restore the contents of the workspace using the contents of a temporary zone

git checkout -- 文件名

• View the status of staging area

git status

Staging Area and warehouse area

• Add a record of a staging area to the warehouse area

git commit -m ‘本次提交的说明信息‘

• View the history of the warehouse area

当前版本的历史版本：git log简版显示：git log --pretty=oneline历史命令：git reflog

• In Git, the current version is represented by head, which is the latest commit 3628164 ... 882E1E0 (Note that my submission ID and your affirmation is not the same), the previous version is head^, the last version is head^^, of course, 100 to write 100 ^ more easy to count, so write head~100

• Compare the differences between a version of a file in a workspace and a warehouse area

git diff HEAD -- 文件名

• Fallback historical version to staging area

git reset HEAD^或版本号

deleting files

• Execute the following command sequentially

rm 文件名git rm 文件名git commit -m ‘说明信息‘
