html

 
千万注意form 中要指定enctype="multipart/form-data" 不然get就是一个None.


<div class="form-group col-sm-offset-2 col-sm-10">
    <label for="exampleInputFile">File input</label>
    <input type="file" name="fi" id="exampleInputFile"> <br>
  </div>

def up_file(request):
    if request.method == "GET":
        return render(request, "up_file.html")


    if request.method == "POST":
        # if request.user.is_anonymous():
        #     return redirect(\'/login\')
        srf_nu = request.POST.get(\'srf_nu\')
        start_date = request.POST.get(\'start_date\')
        receivce_date = request.POST.get(\'receivce_date\')
        myfile = request.FILES.get(\'fi\')

        if not myfile:
            return HttpResponse("no files for upload!")

        destination = open(os.path.join("static",myfile.name), \'wb+\')
        for chunk in myfile.chunks():
            destination.write(chunk)
        destination.close()
        Srf.objects.create(srf=srf_nu,file_path=\'static/%s\'%myfile.name,createdate=start_date,recedate=receivce_date)
        return redirect(\'/labsmith/checklist\')
