'InMemoryUploadedFile' object has no attribute 'get'

问题

I'm having trouble getting images to upload to an S3 bucket from Django

The error I'm getting is:

'InMemoryUploadedFile' object has no attribute 'get'

I've looked at similar questions, but haven't found a solution from them (or others not listed below):

ModelForm has no attribute get

Django image uploading

django 'User' object has no attribute 'get' error

Here's my code:

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)

Thank you so much in advance for any help.

回答1:

You shouldn't pass a specific file from the request to the form, you should pass the whole FILES dictionary just as you pass the whole POST.

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