ファイルはアップロードされず、データベースに保存されません

Question

私はdjangoでのファイルの保存とアップロードに問題があります。私はチュートリアル全体を読んでこれを稼働させてきました。私はこれで立ち往生してきました：

問題はviews.pyから来ているようですが、保存の途中で停止します。私は私のアップロード/ views.py

# -*- coding: utf-8 -*- 
from django.shortcuts import render_to_response 
from django.template import RequestContext 
from django.http import HttpResponseRedirect 
from django.core.urlresolvers import reverse 

from upload.models import Files 
from upload.forms import DocumentForm 

# import sys, traceback 

def index(request): 
    # Handle file upload 
    if request.method == 'POST': 
     form = DocumentForm(request.POST, request.FILES) 
     if form.is_valid(): 
      newdoc = Files(file_path = request.FILES['file_path']) 
      newdoc.save() 
      # print(request) 

     # Redirect to the document list after POST 
     return HttpResponseRedirect(reverse('upload.views.index')) 
    else: 
     form = DocumentForm() # A empty, unbound form 

    # Load documents for the list page 
    documents = Files.objects.all() 

    # print(form) 
    print(documents) 
    # Render list page with the documents and the form 
    return render_to_response(
     'upload/index.html', {'documents': documents, 'form': form}, RequestContext(request) 
) 

私のアップロード/ models.py

from django.db import models 

# Create your models here. 
class Files(models.Model): 
    user_id = models.IntegerField() 
    project_id = models.IntegerField() 
    file_path = models.FileField(upload_to='documents/%Y/%m/%d') 
    file_name = models.CharField(max_length=255) 
    file_size = models.CharField(max_length=45) 
    file_type = models.CharField(max_length=45) 
    file_ext = models.CharField(max_length=10) 
    file_width = models.SmallIntegerField() 
    file_height = models.SmallIntegerField() 
    file_tag = models.CharField(max_length=45) 
    location = models.TextField() 
    approved = models.IntegerField() 
    archived = models.IntegerField() 
    restored = models.IntegerField() 
    backup = models.IntegerField() 
    date_upload = models.DateTimeField() 
    date_modified = models.DateTimeField() 

    def __str__(self): 
     return 'file_name:{0}'.format(self.file_name) 

    class Meta: 
     managed = False 
     db_table = 'files'

• 更新：それが今、データベースに保存されます 、私はちょうどnewdoc内のすべてのフィールドを追加しました。私のテーブルは、NULL値を許可しない、問題は、しかしである：

  file_path = request.FILES['file_path'] 
  

Answer 1

FileFieldアップロードされたファイルオブジェクトを表します。だからのファイルで、のパスはではありません。

def index(request): 
    # Handle file upload 
    if request.method == 'POST': 
     form = DocumentForm(request.POST, request.FILES) 
     if form.is_valid(): 
      newdoc = Files(file_path = form.cleaned_data['file_path']) 
      newdoc.save() 
      # print(request) 

documentation on file uploadsはこの点で非常に詳細になります。

Answer 2

私はすでに私の問題を解決していると思うし、この作業をしようとしている他の初心者がいる場合に備えてこのソリューションを投稿しています。注：ファイルフィールドの名前を 'file_path'からDocumentFormにある 'file'に変更すると、名前の混同を避けることができます。

def index(request): 
    # Handle file upload 
    if request.method == 'POST': 
     form = DocumentForm(request.POST, request.FILES) 

     if form.is_valid(): 
      # Upload the File 
      uploaded_file(request) 
      # Save in database 
      newdoc = Files(
       file_path = 'media/'+request.FILES['file_path'].name, 
       file_name = request.FILES['file_path'].name, 
       file_size = request.FILES['file_path'].size, 
       file_type = request.FILES['file_path'].content_type, 
       # Other data fields here.. 
      ) 
      newdoc.save() 

     # Redirect to the document list after POST 
     return HttpResponseRedirect(reverse('upload.views.index')) 
    else: 
     form = DocumentForm() # A empty, unbound form 

    # Load documents for the list page 
    documents = Files.objects.all() 

    # Render list page with the documents and the form 
    return render_to_response(
     'upload/index.html', {'documents': documents, 'form': form}, RequestContext(request) 
    ) 

def uploaded_file(request): 
    uploaded_filename = request.FILES['file_path'].name 

    # save the uploaded file inside that folder. 
    full_filename = 'media/'+uploaded_filename 
    fout = open(full_filename, 'wb+') 

    file_content = ContentFile(request.FILES['file_path'].read()) 

    # Iterate through the chunks. 
    for chunk in file_content.chunks(): 
     fout.write(chunk) 
    fout.close()
