我的上传功能完全适用于我的本地计算机，但无法在生产服务器上运行。代码相同，没有未提交的提交等。
以下是本地计算机上发生的情况：

完美，图片上传等等。
现在，生产服务器上完全相同的操作：

图像在params散列中，但未插入数据库。有人会暗示我走向正确的方向吗？
这是我的projects_controller.rb：
def update
if @project.update(project_params)
if params[:projectphotos]
params[:projectphotos].each { |image| @project.projectphotos.create(image: image) }
end
redirect_to admin_projects_path
flash[:success] = "Updated"
end
end
def edit
end
def show
end
def create
@project = Project.new(project_params)
if @project.save
if params[:projectphotos]
params[:projectphotos].each { |image| @project.projectphotos.create(image: image) }
end
redirect_to admin_projects_path
flash[:success] = 'Created'
else
flash[:alert] = 'Something went wrong'
render 'new'
end
end
这个完全相同的代码已经在生产的某个时间用于生产，但我想在某些时候，在我添加ImageMagick进行调整后它停止工作。我转而使用MiniMagick，而在其他项目中，调整大小和图像上传与MiniMagick配合得很好，这里我有关于制作的这个问题。说实话，这就是为什么我不相信，这个问题是由MiniMagick引起的，只是想分享这些信息。
更新： 根据要求，这是我的上传代码：
# encoding: utf-8
class ImageUploader < CarrierWave::Uploader::Base
# Include RMagick or MiniMagick support:
# include CarrierWave::RMagick
include CarrierWave::MiniMagick
# Choose what kind of storage to use for this uploader:
storage :file
# storage :fog
# Override the directory where uploaded files will be stored.
# This is a sensible default for uploaders that are meant to be mounted:
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
# Create different versions of your uploaded files:
# version :thumb do
# process :resize_to_fit => [50, 50]
# end
version :thumb_next do
process :resize_to_fill => [600, 460]
end
version :main_image do
process :resize_to_fill => [1170, 700]
end
version :thumb_small do
process :resize_to_fit => [50,50]
end
version :thumb_medium do
process :resize_to_fit => [350,350]
end
end
更新2： 这变得更加荒谬，我添加了一些简单的输出来调试我的生产代码：
projects_controller.rb
def update
if @project.update(project_params)
if params[:projectphotos]
p "inside params"
params[:projectphotos].each do |image|
p image
p "inside of each image param"
if @project.projectphotos.create(image: image)
p "created image"
end
end
end
redirect_to admin_projects_path
flash[:success] = "Updated"
end
end
有了这个更新，我就会在生产中得到这个：

"inside of each image param"
"created image"
但仍然没有图像，仍然没有INSERT sql-queries！ Projectphoto.all显示没有条目，虽然它显然应该创建了一个图像。
答案 0 :(得分：0)
好的，显然我的生产服务器上没有安装imagemagick。
我遇到的问题 - 执行“创建”操作时没有错误消息，也没有回滚。相反，我重写了我的控制器使用'build'和'save'。
def update
if @project.update(project_params)
if params[:projectphotos]
p "inside params"
params[:projectphotos].each do |image|
p image
p "inside of each image param"
@newImage = @project.projectphotos.build(image: image)
if @newImage.save
p "saved image"
end
end
end
redirect_to admin_projects_path
flash[:success] = "Обновлено"
end
end
这给了我至少一次回滚。
由于这个SO问题how to find the cause of ActiveRecord ROLLBACK，我能够调试回滚（重要的是用BANG保存文件 - '！'）。这最终导致了一些可以理解的错误：
2.2.0 :011 > @pr.save!
(1.0ms) BEGIN
(0.4ms) ROLLBACK
ActiveRecord::RecordInvalid: Validation failed: Projectphotos image Failed to manipulate with MiniMagick, maybe it is not an image? Original Error: ImageMagick/GraphicsMagick is not installed
也许对某人有所帮助。
答案 1 :(得分：-1)
请检查是否已安装ImageMagick / GraphicsMagick
