小編使用python中的django框架來完成！
這里小編默認(rèn)項(xiàng)目都會創(chuàng)建
settings.py中要修改的兩處配置
DATABASES = {
'default': {
# 'ENGINE': 'django.db.backends.sqlite3',
# 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
'ENGINE': 'django.db.backends.mysql',
'NAME': 'photos',
'HOST': '127.0.0.1',
'PORT': '3306',
'USER': 'root',
'PASSWORD': '201314',
}
}
STATIC_URL = '/static/'
STATICFILES_DIRS = [
os.path.join(BASE_DIR, 'static')
]
①先按鍵盤上win+s鍵，然后輸入cmd，中文輸入法兩下回車，英文輸入法一下回車，即可進(jìn)入dos窗口。
②輸入 mysql -uroot -p密碼 回車進(jìn)入mysql數(shù)據(jù)庫，再輸入 create database 表名; 一個小回車，創(chuàng)建數(shù)據(jù)庫🆗
③在app下的models.py中創(chuàng)建表結(jié)構(gòu)
models.py
from django.db import models
# Create your models here.
class Images(models.Model):
img = models.ImageField(upload_to='static/pictures/') # upload_to='static/pictures/'是指定圖片存儲的文件夾名稱，上傳文件之后會自動創(chuàng)建
img_name = models.CharField(max_length=32)
create_time = models.DateTimeField(auto_now_add=True)
④遷移數(shù)據(jù)庫
分別按順序在pycharm下面的Terminal中執(zhí)行下面兩條語句
python manage.py makemigrations python manage.py migrate

6，整體演示一遍
因?yàn)闀r間緊，故以最low方式簡要實(shí)現(xiàn)，并沒有加上漂亮的頁面和樣式，喜歡美的看客朋友可自行去Bootstrap官網(wǎng)或jq22自行添加！??！
