Django中sql与DB的交互——非ORM

Posted 2020-10-03

In your views.py,you can code like this :

 1 import mysqldb
 2 def index(request):
 3     conn=MySqldb.connect(
 4         host=‘127.0.0.1‘,
 5         port=3306,
 6         user=‘root‘,
 7         passwd=‘root‘,
 8         db=‘pythonweb‘,
 9         charset=‘utf8‘,     #须与建立数据库时编码一致
10 
11         )
12     cursor=conn.cursor()   #定义游标
13     cursor.execute("SELECT * FROM firstapp_article")
14     results=cursor.fetchmany()
15 
16     articles=[]
17     for result in  results:
18         articles.append(
19             {
20                 # 这里与数据库中定义的表相匹配关联
21                 #result[0]为id
22                 ‘title‘:result[1],
23                 ‘content‘:result[2],
24                 ‘views‘:result[3],
25                 ‘likes‘:result[4],
26                 ‘createtime‘:result[5],
27                 ‘editors_choice‘:result[6],
28                 ‘cover‘:result[7],
29                 ‘url_image‘:result[8],
30             }
31 
32         )
33         context={}
34         context[‘articles‘]=articles
35     return render(request,‘index.html‘,context)
