直接跳过ORM的方式，ORM方式过于繁琐，对于复杂查询更是无力
HelloWorld/HelloWorld/是我建立的项目
vim settings #HelloWorld/HelloWorld目录下修改如下代码
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', # 或者使用 mysql.connector.django
'NAME': 'test',
'USER': 'root',
'PASSWORD': '123456',
'HOST':'127.0.0.1',
'PORT':'3306',
},
'db1': {
'ENGINE': 'django.db.backends.mysql', # 或者使用 mysql.connector.django
'NAME': 'test2',
'USER': 'root',
'PASSWORD': '123456',
'HOST':'127.0.0.1',
'PORT':'3306',
}
}
vim views.py #blog目录下添加个函数
from django.db import connection
from django.db import connections
def db_handle(request):
t = loader.get_template('db_handle.html')
#cursor = connection.cursor()
#cursor.execute("select * from test")
#rows = cursor.fetchall()
cursor = connections['db1'].cursor()
cursor.execute("select * from Poem")
rows = cursor.fetchall()
d = {"name":"lidonghai","age":29,"sex":"mail","user":rows}
return HttpResponse(t.render(d))
vim urls.py #blog目录下，内容如下
from django.conf.urls import url
from blog import views
urlpatterns = [
url(r'^hello/$', views.hello),
url(r'^search/$', views.search),
url(r'^post_search/$', views.post_search),
url(r'^search_submit$', views.search_submit),
url(r'^post_search_submit$', views.post_search_submit),
url(r'^db_handle/$', views.db_handle),
]
vim db_handle.html #blog目录下templates目录下
{{ user }}
启动server后，浏览器访问测试：http://10.1.8.34:8000/blog/db_handle/
