小编使用python中的django框架来完成！
这里小编默认项目都会创建
settings.py中要修改的两处配置
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先按键盘上win+s键，然后输入cmd，中文输入法两下回车，英文输入法一下回车，即可进入dos窗口。
②输入 mysql -uroot -p密码 回车进入mysql数据库，再输入 create database 表名; 一个小回车，创建数据库🆗
③在app下的models.py中创建表结构
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/'是指定图片存储的文件夹名称，上传文件之后会自动创建
img_name = models.CharField(max_length=32)
create_time = models.DateTimeField(auto_now_add=True)
④迁移数据库
分别按顺序在pycharm下面的Terminal中执行下面两条语句
python manage.py makemigrations python manage.py migrate
urls.py
from django.conf.urls import url
from django.contrib import admin
from app01 import views
urlpatterns = [
url(r'^admin/$', admin.site.urls),
url(r'^upload/$', views.upload, name='upload'),
]
views.py
from django.shortcuts import render, redirect
from app01 import models
# Create your views here.
def upload(request):
error = ''
if request.method == 'POST':
img = request.FILES.get('img')
pic_name = img.name
if pic_name.split('.')[-1] == 'mp4':
error = '暂不支持上传此格式图片！！！'
else:
models.Images.objects.create(img_name=pic_name, img=img)
return redirect('show')
return render(request, 'upload.html', locals())
前端上传页面upload.html
上传照片
urls.py
"""
from django.conf.urls import url
from django.contrib import admin
from app01 import views
urlpatterns = [
url(r'^admin/$', admin.site.urls),
url(r'^upload/$', views.upload, name='upload'),
url(r'^show/$', views.show, name='show'),
]
views.py
from django.shortcuts import render, redirect
from app01 import models
# Create your views here.
def upload(request):
error = ''
if request.method == 'POST':
img = request.FILES.get('img')
pic_name = img.name
if pic_name.split('.')[-1] == 'mp4':
error = '暂不支持上传此格式图片！！！'
else:
models.Images.objects.create(img_name=pic_name, img=img)
return redirect('show')
return render(request, 'upload.html', locals())
def show(request):
all_images = models.Images.objects.all()
# for i in all_images:
# print(i.img)
return render(request, 'show.html', locals())
前端展示show.html
展示照片
{% for image in all_images %}
{% endfor %}
urls.py
from django.conf.urls import url
from django.contrib import admin
from app01 import views
urlpatterns = [
url(r'^admin/$', admin.site.urls),
url(r'^upload/$', views.upload, name='upload'),
url(r'^show/$', views.show, name='show'),
url(r'^delete/$', views.delete, name='delete'),
]
views.py
from django.shortcuts import render, redirect
from app01 import models
# Create your views here.
def upload(request):
error = ''
if request.method == 'POST':
img = request.FILES.get('img')
pic_name = img.name
if pic_name.split('.')[-1] == 'mp4':
error = '暂不支持上传此格式图片！！！'
else:
models.Images.objects.create(img_name=pic_name, img=img)
return redirect('show')
return render(request, 'upload.html', locals())
def show(request):
all_images = models.Images.objects.all()
# for i in all_images:
# print(i.img)
return render(request, 'show.html', locals())
def delete(request):
pk = request.GET.get('pk')
models.Images.objects.filter(id=pk).delete()
return redirect('show')
show.html
6，整体演示一遍
因为时间紧，故以最low方式简要实现，并没有加上漂亮的页面和样式，喜欢美的看客朋友可自行去Bootstrap官网或jq22自行添加！！！
