我有上傳圖片與我的文件上傳字段的一些問題。它不會上傳任何東西。但圖像網址字段的作品。我認爲這與我的模型有關。Rails回形針文件上傳字段不工作 - 多選圖片上傳
我的形式:
<%= simple_form_for [:admin, @virksomhed] do |f| %>
<%= f.simple_fields_for :link_attributes do |d| %>
<% end %>
<%= f.simple_fields_for :photo_attributes do |d| %>
<%= d.label :image, :label => 'Upload logo', :required => false %>
<%= d.file_field :image, :label => 'Image, :required => false', :style => 'margin-bottom:2px' %>
<%= d.input :image_url, :label => 'Billed URL', :required => false %>
<% end %>
<%= f.submit "Opret virksomhed" %>
<% end %>
我的照片模式:
require 'open-uri'
class Photo < ActiveRecord::Base
belongs_to :virksomhed
attr_accessor :image_url
has_attached_file :image,
:url => "/public/images/billeder/photo/:id/:basename.:extension",
:path => ":rails_root/public/images/:id/:basename.:extension"
before_validation :download_remote_image, :if => :image_url_provided?
private
def image_url_provided?
!self.image_url.blank?
end
def download_remote_image
self.image = do_download_remote_image
self.image_remote_url = image_url
end
def do_download_remote_image
io = open(URI.parse(image_url))
def io.original_filename; base_uri.path.split('/').last; end
io.original_filename.blank? ? nil : io
rescue # catch url errors with validations instead of exceptions (Errno::ENOENT, OpenURI::HTTPError, etc...)
end
end
我virksomhed型號:
class Virksomhed < ActiveRecord::Base
has_one :photo
accepts_nested_attributes_for :photo
end
這對於本地和遠程文件都會失敗嗎? – Nick
編輯!:只有遠程文件有效(帶有圖片url字段)我認爲它的確有一些關於值 –
