django web界面上传下载文件

@Py站长

之前看到这儿了，就是参考的它，可是重写FormView的post方法，接下来怎么用到我自己的upload上传视图函数里呢？最近需要什么功能时就百度谷歌加查文档，但总是觉得解决一个问题好费劲。。。

`

class FileFieldView(FormView): form_class = UserForm template_name = 'upload.html' def post(self,request,args,*kwargs): form_class = self.get_form_class() form = self.get_form(form_class) files = request.FILES.getlist('rawFile') if form.is_valid(): for f in files: print f #do something with each file return self.form_valid(form) else: return self.form_invalid(form)

def upload(request): if request.method == "POST": uf = UserForm(request.POST,request.FILES)
if uf.is_valid():
username = uf.cleaned_data['username'] rawFile = uf.cleaned_data['rawFile'] return render_to_response('uploadDone.html',{'rawFile':rawFile}) else: uf = UserForm() return render_to_response('upload.html',{'uf':uf})

 from django.views.generic.edit import FormView
from .forms import FileFieldForm

class FileFieldView(FormView):
    form_class = FileFieldForm
    template_name = 'upload.html'  # Replace with your template.
    success_url = '...'  # Replace with your URL or reverse().

    def post(self, request, *args, **kwargs):
        form_class = self.get_form_class()
        form = self.get_form(form_class)
        files = request.FILES.getlist('file_field')
        if form.is_valid():
            for f in files:
                ...  # Do something with each file.
            return self.form_valid(form)
        else:
            return self.form_invalid(form)

@Py站长 看到官方文档提到 forms.py>

     file = forms.FileField(widget=forms.ClearableFileInput(attrs={'multiple':True}))

views.py> 重写FormView的post方法

对于一次上传多个文件到本地up_load，同时保存到models（myslq数据库），具体是怎么实现的，我现在需要一次同时上传两个文件，对两个文件同时做其他处理，多谢。希望回复我邮件吧 freeknighter@sina.com

@Rambo 确实有风险。。。是我的问题。感谢你的建议，我已经修复了：）

前端模板html中加入

* <form enctype="multipart/form-data" action="/uploadFile/" method="post">  
*    <input type="file" name="myfile" />  
*    <br/>  
*    <input type="submit" value="upload"/>  
* </form>

• 用form来上传文件

后端

def upload_file(request):  
        if request.method == "POST":    # 请求方法为POST时，进行处理  
                myFile =request.FILES.get("myfile", None)    # 获取上传的文件，如果没有文件，则默认为None  
                if not myFile:  
                        returnHttpResponse("no files for upload!")  
                destination = open(os.path.join("E:\\upload",myFile.name),'wb+')    # 打开特定的文件进行二进制的写操作  
                for chunk in myFile.chunks():      # 分块写入文件  
                        destination.write(chunk)  
                destination.close()  
                returnHttpResponse("upload over!")

@Py站长 这有注入的危险呀。。。。。
