我正在使用CarrierWave gem，我的问题是它不会将我保存在数据库中，它只会将我上传到uploads文件夹，我已经按照文档的要求在模型中进行了很好的配置。默认的图像是配置好的，它完美地显示了我。所有其他数据都保存了，除了照片。在控制器中，允许在参数中使用字符串类型。在我的环境中添加要求'carrierwave/orm/activerecord'。rb文件我不知道是什么错误。
我的模型:
class Profile < ApplicationRecord
belongs_to :user
mount_uploader :foto, FotoUploader
end
我的控制器:
def profile_params
params.require(:profile).permit(:foto, :titulo, :matricula,
:biografia, :telefono, :whatsapp, :provincia, :localidad,
:direccion, :cpostal, :idiomas, :areas, :edades, :escuelas,
:urgencias, :osociales, :tdomicilio, :presencial, :online,
:precioconsulta, :formadepago, :cuit, :iva)
end
我的观点(编辑):
<div class="col-xl-4">
<%= f.file_field :foto %>
</div>
我的观点(显示):
<div class="avatar">
<%=image_tag @profile.foto.url%>
</div>
我的上传:
class FotoUploader < 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
# Provide a default URL as a default if there hasn't been a file uploaded:
def default_url(*args)
# # For Rails 3.1+ asset pipeline compatibility:
ActionController::Base.helpers.asset_path('avatar.png')
#
# "/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_fill: [150, 150]
end
# Add an allowlist of extensions which are allowed to be uploaded.
# For images you might use something like this:
def extension_allowlist
%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

可能是我没有保存，因为foto字段生成超过255个字符和字符串字段只接受255?
如果您的上传程序使用storage :file，那么将文件保存到文件系统是预期的行为。有一些gem提供数据库存储。例如载波-postgresql。大多数使用载波的人不希望将文件存储在本地文件系统中，将其与云存储系统(如S3)一起使用
问题是没有安装ImageMagick。问题解决了
