Question

我试图更改图像的大小，但是当我运行代码时，它显示此错误：`AttributeError：模块'PIL.Image'没有属性'_meta' 这是我的models.py文件：

from django.db import models
from PIL import Image

class LmtbProject(models.Model):
title = models.CharField(max_length=200)
description = models.TextField()
public = models.BooleanField(default=True)
LmtbImage = models.ImageField(blank=True)

def __str__(self):
    return f'{self.title}'
def save(self):
    super().save()

    img = Image.open(self.LmtbImage.path)
    output_size = (1000, 800)
    img.thumbnail(output_size)
    img.save(self.LmtbImage.path)

class SecondaryImage(models.Model):
MyProject = models.ForeignKey(LmtbProject, default=None, on_delete=models.CASCADE)
image = models.ImageField(upload_to='images/')

def __str__(self):
    return f'{self.MyProject.title}'

def save(self):
    super().save()

    img = Image.open(self.image.path)
    output_size = (1000, 800)
    img.thumbnail(output_size)
    img.save(self.image.path)

`这是我的看法：

def project(request):
projects = LmtbProject.objects.all()
context = {
    'projects': projects
}
return render(request, 'projects.html', context)

def project_detail(request, id):
project = get_object_or_404(LmtbProject, id=id)
photos = SecondaryImage.objects.filter(MyProject=project)
return render(request, 'project-detail.html', {'project': project, 'photos': photos})

（AttributeError：模块“ PIL.Image”没有属性“ _meta”）使用枕头调整图像大小时
