在localhost中，我的项目运行得很好，但是每次我部署到heroku时，我都会收到错误.....我还运行了Heroku run rake db：migrate。知道这是怎么回事吗？

2条答案
按热度按时间2exbekwf1#
这是您的错误：
问题似乎是
listing.image.url的路径无法识别。我不知道为什么Rails将此视为致命错误（通常，它只会显示带有“未找到”图像的HTML
img），但在这种情况下，它会导致整个Rails应用程序失败。解决方法（使其正常工作）是从
app/views/listings/index.html.erb文件中删除<%= image_tag listing.image.url %>。这不是一个修复程序，但应该可以解决当前的问题。
1.确保回形针文件完好无损
1.确保数据库具有正确的引用
问题似乎是
/original/1_maxresdefault.jpg不存在。YouTube使用了这个图片名称，所以我怀疑你要么是在删除YouTube的封面图片，要么是在模仿YouTube的视频处理结构。
无论采用哪种方式，应用程序中的文件夹结构都应如下所示：
public/system/[model]/[attachment]/[other_options]/[sizes]/[file].[extension]在我看来，您的路径没有被正确调用，或者您没有正确的文件名。您可能手动填充了文件名或其他内容。
我会亲自删除整个
/public/system文件夹（它是Paperclips的），删除所有引用附件在您的数据库和通过我所有的listings上传新的图像。然后我会确保
public/system存在于git push中（你可以通过检查它不在.gitignore中来确保这一点），然后再次推送到Heroku。还要确保Heroku的数据库结构模仿您的开发环境--可能会出现 production 数据库中引用的映像不存在的情况。
