'InMemoryUploadedFile' 对象没有属性 'get'

Question

我无法从 Django 将图像上传到 S3 存储桶

我得到的错误是：

'InMemoryUploadedFile' object has no attribute 'get'

我看过类似的问题，但没有从中找到解决方案（或其他未在下面列出的问题）：

Django image uploading

这是我的代码：

forms.py

from django import forms
from .models import UploadImage, UploadAudio

class ImageForm(forms.ModelForm):
class Meta:
    model = UploadImage
    fields = ['myimage']

views.py

from django.contrib import messages
from django.shortcuts import render, get_object_or_404, redirect
from django.http import HttpResponse, HttpResponseRedirect
from django.shortcuts import redirect
from .forms import ImageForm, AudioForm
from .models import UploadImage


def ImageCreate(request):
    if request.method == 'POST':
        form = ImageForm(request.POST, request.FILES['myimage'])
        if form.is_valid():
            image = form.save(commit=False)
            image.author = request.user
            image.save()
            messages.success(request, "Uploaded successfully")
            return redirect('mytimer')
        else:
            messages.error(request, "Unable to upload at this time")
else:
    form = ImageForm()
return render(request, "myimages.html", {'form': form})

models.py

from __future__ import unicode_literals

from django.db import models
from django.conf import settings


class UploadImage(models.Model):
    """
    Define how the user will upload images
    """
    # link author to registered user
    author = models.ForeignKey(settings.AUTH_USER_MODEL)
    myimage = models.ImageField(upload_to='myimages/')
    uploaded_at = models.DateTimeField(auto_now_add=True)

非常感谢您的帮助。

Answer 1

您不应将特定文件从请求传递到表单，您应该像传递整个 POST.

一样传递整个 FILES 字典

form = ImageForm(request.POST, request.FILES)

Answer 2

我遇到了同样的问题。但我拥有它的原因是因为它是最终 return render() 中的模板错误我的表单没有在函数之前实例化。因此，每当我提交表单并重新加载页面时，填充的表单就会被传递到模板中。 else 和 return 语句似乎也没有正确缩进。那只是我的两分钱。我试图找到我的查询的答案并越过此页面，所以我决定分享这个。
