1.項(xiàng)目搭建
用pycharm 編輯器可以直接 New 一個(gè) Django 項(xiàng)目
2.新建應(yīng)用
python manage.py startapp demo
項(xiàng)目結(jié)構(gòu)如下:
3.編寫第一個(gè)Django 視圖函數(shù)
/demo/views:
from django.http import HttpResponse
def welcome(request):
return HttpResponse("welcome to django")
/djangoProject/urls:
from django.urls import path, include
urlpatterns = [
path("welcome/", include("demo.urls")),
# path('admin/', admin.site.urls),
]
/demo/urls:
from django.urls import path
from . import views
urlpatterns = [
path("", views.welcome, name="welcome")
]
4.Django 配置MySQL數(shù)據(jù)庫
/djangoProject/settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'db_django',
'USER': 'root',
'PASSWORD': 'mysql數(shù)據(jù)庫密碼',
'HOST': '127.0.0.1',
'PORT': '3306'
}
}
/demo/models
class CookInfo(models.Model):
cook_name = models.CharField(max_length=32, default='CookName')
cook_price = models.DecimalField(max_digits=10, decimal_places=3)
cook_img = models.ImageField(upload_to='photos', default='cook1.png')
執(zhí)行下面命令
pip install pymysql
python manage.py makemigrations
執(zhí)行上面這個(gè)會(huì)報(bào)錯(cuò) ModuleNotFoundError: No module named ‘MySQLdb’
需要在項(xiàng)目的 init.py 文件里面指定使用mysql數(shù)據(jù)庫文章來源：http://www.zghlxwxcb.cn/news/detail-718268.html
import pymysql
pymysql.install_as_MySQLdb()
最后執(zhí)行，就能在數(shù)據(jù)庫中看到新建的數(shù)據(jù)表了文章來源地址http://www.zghlxwxcb.cn/news/detail-718268.html
python manage.py migrate
