Djangomysqlclient安装和使⽤详解
⼀、安装mysqlclient
⽹上看到很过通过命令:pip install mysqlclient 进⾏安装的教程,但是我却始终安装失败,遇到的错误千奇百怪,后来通过⾃⼰下载mysqlclient客户端终于安装成功;
下载好mysqlclientt之后如下(只要下载1个,我系统是64位,所以先下载的64位的,结果⽤不了,所以⼜下载了32位的才成功,所以建议先下载32位的试试):
打开控制台(开始->运⾏->cmd):
第⼀步:cd 到下载的mysqlclient⽂件所在的⽬录:cdC:\Users\Yeat\Downloads\mysqlclient
第⼆步:执⾏安装命令:pip installmysqlclient-1.4.4-cp38-cp38-win32.whl
如果成功的话会看到:
C:\Users\Yeat\Downloads>pip install mysqlclient-1.4.4-cp38-cp38-win32.whl
Processing c:\users\yeat\downloads\mysqlclient-1.4.4-cp38-cp38-win32.whl
Installing collected packages: mysqlclient
Successfully installed mysqlclient-1.4.4
C:\Users\Yeat\Downloads>当然如果失败的话,那很可能看到类似下图的画⾯:
C:\Users\Yeat>pip install mysqlclient‑1.3.13‑cp36‑cp36m‑win_amd64.whl
WARNING: Requirement 'mysqlclient‑1.3.13‑cp36‑cp36m‑win_amd64.whl' looks like a filename, but the file does not exist

ERROR: MySQL_python-1.2.5-cp27-none-win_amd64.whl is not a supported wheel on this platform.

ERROR: mysqlclient-1.4.4-cp38-cp38-win_amd64.whl is not a supported wheel on this platform.
失败,那就换下载的mysqlclient版本,只能提供这个办法了
⼆、在Django框架⾥使⽤mysql
mysql下载32位1.进⼊项⽬⼯程⽬录执⾏命令:django-admin startapp TcesApp,我的完整命令是:C:\Users\Yeat\PycharmProjects\untitled>django-admin startapp TcesApp,前⾯的部分是我的⼯程⽬录路径;
2.命令执⾏完毕后⼯程⾥会增加TcesApp⽬录如图:
3.进⼊models.py中创建与你的数据库表相对应的对象model,我的内容如下:
from django.db import models
class e_exams(models.Model):
ID = models.CharField(max_length=50),
ExamName = models.CharField(max_length=50)
ExamCode = models.CharField(max_length=50)
SceneID = models.CharField(max_length=50)
Creater = models.CharField(max_length=50)
CreateTime = models.DateTimeField()
State = models.CharField(max_length=50)
Field_Char1 = models.CharField(max_length=50)
Field_Char2 = models.CharField(max_length=50)
Field_Char3 = models.CharField(max_length=50)
class Meta:
db_table = 'e_exams' #数据表名称
我的表结构 e_exams:
在models.py中可以创建过个表的model。
4.在admin.py中注册model:
ib import admin
from . import models
# Register your models here.
ister(models.e_exams)
5.在setting.py中添加app名称(上边的名称 django-admin startapp TcesApp 的名称):
6.还是在settings.py中修改DATABASES内容如下:
完整配置:
DATABASES = {
'default': {
'ENGINE': 'django.sql',
'NAME': 'tces',
'USER': 'root',
'PASSWORD': 'Unity3du#d112233',
'HOST': 'atsoft',
'PORT': '3306',
'OPTIONS': {
"init_command": "SET sql_mode='STRICT_TRANS_TABLES'",
}
}
}
其中NAME是你的数据库名称,HOST是数据库地址,其它的⼤家都知道。
7.接下来我们到views.py(或者⾃⼰创建的py⽂件)中编写代码主要看 addExam 这个⽅法:from django.http import HttpResponse
from django.shortcuts import render
dels import e_exams
def hello(request):
return HttpResponse('home page!')
def helloworld(request):
context = {}
context['value'] = 'hello world!'
return render(request, 'helloworld.html', context)
def addExam(request):
exam = e_exams()
exam.ID = '100001'
exam.SceneID = '1001',
exam.ExamName = '期末考试'
exam.save()
context = {}
context['value'] = exam.ExamName + '数据添加成功!'
return render(request,'helloworld.html',context)
其中helloworld.html是放在templates中的前端页⾯:
context['value']就是html页⾯中的{{value}}
8.到urls.py中添加路径完整代码如下:
ib import admin
from django.urls import path
from . import home
urlpatterns = [
path('admin/', admin.site.urls),
path('home/', home.hello),
path('helloworld/', home.helloworld),
path('add/',home.addExam)
]
三、运⾏效果如下:
