Django文件上传，供大家参考，具体内容如下
需求
1、完成学生信息注册操作
2、将学生信息入库
3、将上传文件存放至项目下media文件夹下
4、显示所有学生信息
创建模型类
class Student(models.Model):
sno = models.AutoField(primary_key=True)
sname = models.CharField(max_length=30)
photo = models.ImageField(upload_to=\'imgs\')
<!--内部类写法 数据库中的名字-->
class Meta:
db_table = \'t_stu\'
def __str__(self):
return self.sname
settings.py文件中文件上传相关设置
INSTALLED_APPS = [
...
\'stu\'
]
DATABASES = {
\'default\': {
\'ENGINE\': \'django.db.backends.mysql\',
\'NAME\': \'django22\',
\'USER\': \'root\',
\'PASSWORD\': \'123321\',
\'HOST\': \'127.0.0.1\',
\'PORT\': \'3306\',
}
}
MEDIA_URL = \'/media/\'
<!--设置MEDIA_ROOT 默认为空 模型类中图片上传地址 MEDIA_ROOT+up_load -->
<!--BASE_DIR 为项目录 -->
MEDIA_ROOT = os.path.join(BASE_DIR,\'media\')
映射数据库表
#在终端中敲命令 python manage.py makemigrations test python manage.py migrate
配置URL
主路由
from django.contrib import admin
from django.urls import path, re_path,include
from djurls.settings import MEDIA_ROOT
from stu import urls
from .import views
#配置路由读取后台上传文件
from django.views.static import serve
urlpatterns = [
path(\'test/\',include(\'test.urls\')),
re_path(r\'^media/(?P<path>.*)/$\', serve, {\"document_root\": MEDIA_ROOT}),
#server 视图函数 将MEDIA的路径和正则匹配的模板路径 显示图片
子路由
from django.urls import path
from test import views
urlpatterns = [
path(\'test/\',views.index.as_view()),
path(\'show/\',views.show)
]
创建视图
stu/views.py
import os
from django.http import HttpResponse, HttpResponseRedirect, Http404
from django.shortcuts import render
from django.views import View
from djurls.settings import BASE_DIR
from test.models import Student
<!--通过as_view处理自动获取请求方式-->
class index(View):
def get(self,request):
return render(request,\'load.html\')
def post(self,request):
name=request.POST.get(\'sname\',\'\')
photo=request.FILES.get(\'photo\',\'\')
age=request.POST.get(\'age\',\'\')
<!--进行校验 将文件名的后缀字符串分割 判断-->
extenedname=photo.name[photo.name.rindex(\'.\')+1:]
allowedname=[\'jpg\',\'png\']
if extenedname not in allowedname:
return Http404()
stu=Student.objects.create(sname=name,age=20,photo=photo)
if stu:
return HttpResponse(\'注册成功\')
else:
return HttpResponseRedirect(\'/test/test/\')
def show(request):
stulist=Student.objects.all()
return render(request,\'show.html\',{\'stulist\':stulist})
创建模板
templates/index.html 注册界面
<!DOCTYPE html>
<html lang=\"en\">
<head>
<meta charset=\"UTF-8\">
<title>Title</title>
</head>
<body>
<form action=\"/test/test/\" method=\"post\" enctype=\"multipart/form-data\">
{% csrf_token %}
<p>姓名<input type=\"text\" name=\"sname\"></p>
<p>年龄 <input type=\"number\" name=\"age\"></p>
<p>照片 <input type=\"file\" name=\"photo\"></p>
<input type=\"submit\" value=\"注册\">
</form>
</body>
</html>
show.html 显示数据 加载图片
<!DOCTYPE html>
<html lang=\"en\">
<head>
<meta charset=\"UTF-8\">
<title>Title</title>
</head>
<body>
<table border=\"1px solid black\" cellspacing=\"0px\" width=\"500px\" align=\"center\">
<tr height=\"100px\" align=\"center\">
<td >编号</td>
<td >姓名 </td>
<td >年龄</td>
<td >头像</td>
</tr>
{% for stu in stulist %}
<tr height=\"100px\" align=\"center\">
<td >{{ forloop.counter }} </td>
<td >{{ stu.sname }}</td>
<td >{{ stu.age }}</td>
<td ><img src=\"/media/{{ stu.photo }}\" alt=\"\"></td>
<!--读取photo的路径 在主路由访问 通过server处理并显示-->
</tr>
{% endfor %}
</table>
</body>
</html>
