python+django自动化平台(一键执行sql) 前端vue-element展示

一、开发环境搭建和配置

pip install mysql-connector-pythonpip install PyMySQL

二、django模块目录

dbOperations
├── __init__.py
├── __pycache__
│   ├── __init__.cpython-313.pyc
│   ├── admin.cpython-313.pyc
│   ├── apps.cpython-313.pyc
│   ├── models.cpython-313.pyc
│   └── views.cpython-313.pyc
├── admin.py
├── apps.py
├── migrations
│   ├── __init__.py
│   └── __pycache__
│       └── __init__.cpython-313.pyc
├── models.py
├── tests.py
└── views.py

三、django模块相关代码

***************************settings.py*********************************************#数据库 连接配置 mysql
DATABASES = {'default': {# 数据库引擎'ENGINE': 'django.db.backends.mysql',# 'ENGINE': 'sqlalchemy.create_engine',# 数据库名字'NAME': 'xx',# 数据库用户名'USER': 'xx',# 数据库密码'PASSWORD': 'xx',# 数据库主机地址'HOST': 'xx',# 数据库端口号'PORT': 'xx'}
}

************************************urls************************************urlpatterns = [path('dbOperations/executeSQLView', db_views.executeSQLView,name='execute_sql_view'),
]

**************************************viwes.py************************************import json
import loggingfrom django.db import connection
from django.http import JsonResponse
from django.shortcuts import render
from django.views.decorators.csrf import csrf_exempt

四、前端代码

<template><div class="app-container"><el-card shadow="always"><el-row :gutter="24"><el-input v-model="sqlParam.sql" type="textarea" :rows="10" placeholder="请输入SQL查询" /><el-button type="primary" @click="executeSQL">执行</el-button></el-row></el-card><el-card shadow="always"><el-table v-if="data.length > 0" :data="data" style="width: 100%"><el-table-column v-for="key in Object.keys(data[0])" :key="key" :prop="key" :label="key" /></el-table></el-card></div>
</template><script>
import {executeSQLView
} from '@/api/dataBase/database-request'export default {data() {return {sqlParam: { // 输入框给出默认值sql: ''},data: [],error: ''}},methods: {executeSQL() {this.dataLoading = trueconsole.log('请求参数:' + this.sqlParam)executeSQLView(this.sqlParam).then((res) => {// alert(JSON.stringify(res.data.data))this.data = res.data.datasetTimeout(() => { // 超过指定超时时间  关闭查询的转圈的loading加载动画this.listLoading = false}, 1.5 * 1000)})}}
}
</script><style>
</style>
