在 Django 中通过管理员上传图像答案

【问题标题】：Uploading an Image through Admin in Django在 Django 中通过管理员上传图像

【问题描述】：

我正在尝试通过 Django 管理面板上传图像。我在 Google App Engine 上运行并使用文件传输插件（不确定是否与我遇到的问题有关）。

来自我的 modelys.py：

from django.db import models

# Create your models here.
class CarouselItem (models.Model):
    caption = models.CharField(max_length=200,blank=True)
    order = models.IntegerField()
    carousel_image = models.ImageField(upload_to='uploads/carousel_image/%Y/%m/%d/')
    def __unicode__(self):
        return self.caption

来自 admin.py：

from carousel.models import CarouselItem
from django.contrib import admin
from imperavi.admin import ImperaviAdmin

class carouselAdmin(ImperaviAdmin):
    list_display = ('caption','order')

admin.site.register(CarouselItem, carouselAdmin)

我得到的错误是“没有名为 Image 的模块”。我没有安装 PIL。我需要安装它才能启用此功能吗？

更新：这是导致错误的回溯：

【问题讨论】：

您能发布导致该错误的回溯吗？可能是你需要安装 PIL。
是的，这是对图像的要求
@SimeonVisser 我添加了回溯 cmets

标签： python django django-admin django-models

【解决方案1】：

您需要安装 PIL 或同等产品。在 python 3.x 的情况下枕头。如果您在安装时遇到问题，请告诉我，我有一些并且很容易修复，您只需将路径添加到您的 python.h 。也许现在已经解决了... 在 models.py 中无需添加任何内容

【解决方案2】：

是的，您需要安装 Pil。但在此之前，您需要将 jpeglib 安装到您的服务器（没有此 PIL 无法处理 jpeg 文件）

总之，你可以包括

from django.db.models import ImageField

在你的 models.py 中
