Linux下开发python django程序(设置admin后台管理上传文件和前台上传文件保存数据库)

1.项目创建相关工作参考前面

2.在models.py文件中定义数据库结构

import django.db import models
class RegisterUser(models.Model):
        username=models.CharField(max_length=30)
        headImg = models.FileField(upload_to='./upload/')
        def __unicode__(self):
                return self.username

3.生成数据库

python manage.py syncdb

4运行开发服务器 访问管理员界面

二.前台上传文件保存到数据库

1.生成项目和APP 过程同参考前面

2.设置models.py，urls.py参考前面文章设置

from django.db import models

# Create your models here.

class RegisterUser(models.Model):
    username=models.CharField(max_length=30)
    headImg = models.FileField(upload_to='./upload/')
    def __unicode__(self):
        return self.username

3.views.py定义冲界面取得POST的值和生成上传文件并且保存于数据库中

from django.http import HttpResponse
from django.template import loader,Context,Template
from django.shortcuts import render_to_response
from app1.models import User,Author,Book,RegisterUser
from django import forms

def register(req):
    if req.method == 'POST':
        form = UserForm(req.POST,req.FILES)
        if form.is_valid():
            print form.cleaned_data
            paths='./upload/'+form.cleaned_data['img'].name
            paths1 = paths.encode('utf-8')
            username = form.cleaned_data["name"]
            print paths1
            fp=file(paths,'wb') 
            s=form.cleaned_data['img'].read()
            fp.write(s)
            fp.close()
            ruser = RegisterUser()
            ruser.username = username
            ruser.headImg = paths
            ruser.save()
            return HttpResponse('ok')
        
    else:
      form = UserForm()
    return render_to_response('register.html',{'form':form})
