我試圖通過AJAX上傳圖像，但是，控制器沒有響應。未初始化的常量CarrierWave :: MiniMagic
錯誤：未初始化的常量CarrierWave :: MiniMagic。
這裏是我的代碼：
# encoding: utf-8
class ImagesUploader < CarrierWave::Uploader::Base
# Include RMagick or MiniMagick support:
# include CarrierWave::RMagick
include CarrierWave::MiniMagiC# << Error
# Choose what kind of storage to use for this uploader:
storage :file
# storage :fog
process convert: 'png'
# 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
version :thumb do
process :resize_to_fill => [171,180]
end
# Provide a default URL as a default if there hasn't been a file uploaded:
# def default_url
# # For Rails 3.1+ asset pipeline compatibility:
# # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))
#
# "/images/fallback/" + [version_name, "default.png"].compact.join('_')
# end
# Process files as they are uploaded:
# process :scale => [200, 300]
#
# def scale(width, height)
# # do something
# end
# Create different versions of your uploaded files:
#version :thumb do
# process :resize_to_fit => [50, 50]
#end
# Add a white list of extensions which are allowed to be uploaded.
# For images you might use something like this:
def extension_white_list
%w(jpg jpeg gif png)
end
# Override the filename of the uploaded files:
# Avoid using model.id or version_name here, see uploader/store.rb for details.
# def filename
# "something.jpg" if original_filename
# end
end
和跟蹤：
app/uploaders/images_uploader.rb:8:in
<class:ImagesUploader>' app/uploaders/images_uploader.rb:3:in' app/models/image.rb:2:in<class:Image>' app/models/image.rb:1:in' app/controllers/events_controller.rb:28:in `edit'
感謝。
