django-heroku服务器上未显示图像(媒体) [英] Images(Media) not displaying on django-heroku server

问题描述

当我成功上传图像文件并按设置正确获取图像路径但图像未显示时，我已经在Heroku服务器上上传了我的站点Django应用，这表明服务器中找不到错误的媒体文件 这是设置媒体设置

I had uploaded my site Django app on Heroku server when I upload image file is successfully uploaded and image path as per settings also fetch properly but the image is not displaying it give error media file not found in a server this is settings media setting

    MEDIA_URL = '/media/'
    MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

这是在url.py

urlpatterns = [
    path('admin/', admin.site.urls),
    path('',include('UserView.urls')),
    path('caterer/',include('CaterView.urls')),
]
# if settings.MediaAllow:
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

这是models.py

this is models.py

class TypeofFood(models.Model):
    tyf_id = models.AutoField(primary_key=True,auto_created=True)
    tyf_value = models.CharField(max_length=256)
    tyf_image = models.ImageField(upload_to="typeoffood/", null=True, blank=True,default='default.jfif')

在模板中添加这样的图像

in template it fatch image like this

<center><img src="{{i.tyf_image.url}}" class="img-responsive" style="height: 200px; width: 200px; border-radius:50%" alt="Image of Caterers"></center>

推荐答案

heroku自由阶段不允许存储媒体文件，这就是为什么您的媒体文件在上传后将被删除

heroku free stage is not allow media file store, that's why your media file will be deleted after upload

因为这就像测试目的，如果您想在heroku上上传和存储媒体文件，则可以使用whitenoise之类的第三方，
