我在 Rails 应用程序中使用回形针,但总是收到以下错误:

Mongoid::Errors::Validations (
Problem:
Validation of Mock failed.
Summary:
The following errors were found: Image has contents that are not what they are reported to be
Resolution:
Try persisting the document with valid data or remove the validations.):
app/api/mockaccino/api.rb:23:in `block (2 levels) in <class:API>'
用于测试的 Curl 命令:
curl -X POST -i -F image=@/home/user/workspace/ruby.png -F name=mock http://localhost:3000/api/mock
我正在将图像和名为“name”的参数发送到服务器,并使用此属性和图像创建模型。
型号:
class Mock
include Mongoid::Document
include Mongoid::Paperclip
field :name, type: String
has_mongoid_attached_file :image
validates_attachment_presence :image
validates_attachment_size :image, :less_than => 1.megabytes
validates_attachment_file_name :image, :matches => [/png\Z/, /jpe?g\Z/]
end
Controller (葡萄):
desc "Create an mock."
params do
requires :name, type: String, desc: "Mock name"
requires :image, :type => Rack::Multipart::UploadedFile, :desc => "Image file."
end
post do
mock = Mock.create!(
name: params[:name],
image: ActionDispatch::Http::UploadedFile.new(params[:image])
)
end
最佳答案
curl -i -X POST -H "Content-Type:multipart/form-data" -F image=@\"./ruby.png\";type=image/png;filename=\"ruby.png\"" http://localhost:3000/api/mock
关于ruby-on-rails - 回形针:发现以下错误:图像的内容与报告的内容不同,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/30686150/
