在我的应用程序中,我正在使用Carrierwave上传文件。我使用MiniMagick进行图像大小调整,并将图像保存为大型版本,如下所示:
version :large do
resize_to_limit(100, 100)
end
在视图中我称之为“大”版本:
<%= image_tag @user.avatar.url(:large) %>
在开发环境中,图像显示且路径正确:
<img src="/uploads/user/....">
但是在制作 env中,没有显示图片,因为呈现错误的路径(它会在appname之前添加):
<img src="appname/uploads/user/....">
我使用的是带有Nginx,Unicorn,Capistrano,Ruby 2.0.0p353和Rails 4.0.2的Ubuntu服务器
nginx.conf:
upstream unicorn {
server unix:/tmp/unicorn.appname.sock fail_timeout=0;
}
server {
listen 80 default deferred;
server_name appname.domain.com;
root /home/deployer/apps/appname/current/public;
location ~ ^/(assets)/ {
root /home/deployer/apps/appname/current/public;
gzip_static on; # to serve pre-gzipped version
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri @unicorn;
location @unicorn {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://unicorn;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 4G;
keepalive_timeout 10;
}
载波上传者:
class UserUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
storage :file
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
version :large do
resize_to_limit(100, 100)
end
end
答案 0 :(得分:0)
最后,它正在发挥作用。我不得不从production.rb中删除这一行(我最初放在那里为多个rails应用程序服务):
config.relative_url_root = "/appname"
