使用python从数据库获取数据(在Django框架上)

pip install django

pip install mysqlclient

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'mydatabase',
        'USER': 'myuser',
        'PASSWORD': 'mypassword',
        'HOST': 'localhost',
        'PORT': '3306',
    }
}

from django.db import models

class Person(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)

python manage.py makemigrations
python manage.py migrate

from django.http import HttpResponse
from .models import Person

def index(request):
    persons = Person.objects.all()
    output = ', '.join([p.first_name + ' ' + p.last_name for p in persons])
    return HttpResponse(output)
