[英]uninitialized constant CarrierWave::MiniMagic
I'm trying to upload an image via AJAX, but, the controller doesn't respond. 我正在尝试通过AJAX上传图像,但是,控制器没有响应。
Error: uninitialized constant CarrierWave::MiniMagic. 错误:未初始化的常量CarrierWave :: MiniMagic。
Here is my code: 这是我的代码:
# 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
and the trace: 和痕迹:

Thanks. 谢谢。
include CarrierWave::MiniMagick
你最后错过了'k'。
I guess you have forgot to mount the image up loader. 我想你已经忘了装载图片了。 Hope this link will help you
