python如何操作git

安装

pip3 install gitpython

基本使用

# 从远处仓库下载代码到本地
import os
from git.repo import Repo

# 创建本地存储地址
download_path = os.path.join('jason','NB')
# 从远程仓库下载代码
Repo.clone_from('https://github.com/DominicJi/TeachTest.git',to_path=download_path,branch='master')

常用方法大全

# ############## 2. pull最新代码 ##############
import os
from git.repo import Repo
 
local_path = os.path.join('jason', 'NB')
repo = Repo(local_path)
repo.git.pull()

# ############## 3. 获取所有分支 ##############
import os
from git.repo import Repo
 
local_path = os.path.join('jason', 'NB')
repo = Repo(local_path)
 
branches = repo.remote().refs
for item in branches:
    print(item.remote_head)
    
# ############## 4. 获取所有版本 ##############
import os
from git.repo import Repo
 
local_path = os.path.join('jason', 'NB')
repo = Repo(local_path)
 
for tag in repo.tags:
    print(tag.name)

# ############## 5. 获取所有commit ##############
import os
from git.repo import Repo
 
local_path = os.path.join('jason', 'NB')
repo = Repo(local_path)
 
# 将所有提交记录结果格式成json格式字符串 方便后续反序列化操作
commit_log = repo.git.log('--pretty={"commit":"%h","author":"%an","summary":"%s","date":"%cd"}', max_count=50,
                          date='format:%Y-%m-%d %H:%M')
log_list = commit_log.split("
")
real_log_list = [eval(item) for item in log_list]
print(real_log_list)
 
# ############## 6. 切换分支 ##############
import os
from git.repo import Repo
 
local_path = os.path.join('jason', 'NB')
repo = Repo(local_path)
 
before = repo.git.branch()
print(before)
repo.git.checkout('master')
after = repo.git.branch()
print(after)
repo.git.reset('--hard', '854ead2e82dc73b634cbd5afcf1414f5b30e94a8')
 
# ############## 7. 打包代码 ##############
with open(os.path.join('jason', 'NB.tar'), 'wb') as fp:
    repo.archive(fp)

封装成类

需要使用直接拷贝即可

项目代码

服务器管理

class Project(models.Model):
    """
    项目表
    """
    title = models.CharField(max_length=32,verbose_name='项目名')
    repo = models.CharField(max_length=255,verbose_name='仓库地址')
    # choices参数
    env_choices = (
        ('prod','正式'),
        ('test','测试')
    )
    env = models.CharField(max_length=16,verbose_name='环境',choices=env_choices,default='test')

代码优化

1.公用添加页面

2.将所有的modlform单独开设文件夹存储

3.对modelform再次优化 对modelform定义一个父类

from django.forms import ModelForm
class BaseModelForm(ModelForm):
    # 将不需要bootstrap样式的字段放入
    exclude_bootstrap = []
    def __init__(self,*args,**kwargs):
        super().__init__(*args,**kwargs)
        # 给字段加上form-control样式
        # self.fields = {'字段名':字段对象}
        for k,field in self.fields.items():
            if k in self.exclude_bootstrap:  # 排除不需要加样式的字段
                continue
            field.widget.attrs['class'] = 'form-control'
                    
# 其他modelform书写
from app01 import models
from app01.myform.mybase import BaseModelForm
class ProjectModelForm(BaseModelForm):
    class Meta:
        model = models.Project
        fields = '__all__'

4.给项目表新增线上项目地址和服务器字段

# 扩展字段
    path = models.CharField(max_length=255,verbose_name='线上项目地址',default='/data/tmp')
    # 项目与服务器的关系表
    servers = models.ManyToManyField(to='Server',verbose_name='关联服务器')
