python - “InMemoryUploadedFile”对象没有属性 'get'

Question

我在将图像从 Django 上传到 S3 存储桶时遇到问题

我收到的错误是:

'InMemoryUploadedFile' object has no attribute 'get'

我看过类似的问题，但没有找到解决方案(或下面未列出的其他问题):

ModelForm has no attribute get

Django image uploading

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

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)

提前非常感谢您提供的帮助。

您不应该将特定文件从请求传递到表单，您应该传递整个 FILES 字典，就像传递整个 POST 一样。

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