我有，我需要上传的Rails 3.2文件（.txt），无需使用任何外部宝石做腿部的工作（非流通只怕）文件也需要保存到数据库的任务。 我有以下的代码，但是当我尝试上载/创建使用它回来与错误的形式新的附件;
No route matches [POST] "/attachments/create"
看起来不像创建操作被称为从模型uploaded_file，但我不知道如何纠正它。 如果任何人都可以在正确的方向点我将不胜感激。
所以我的代码如下;
AttachmentsController.rb
class AttachmentsController < ApplicationController
def show
@attachment = Attachment.find(params[:id])
end_data @attachment.data, :filename => @attachment.filename, :type => @attachment.content_type
end
def create
return if params[:attachment].blank?
@attachment = Attachment.new
@attachment.uploaded_file = params[:attachment]
if @attachment.save
flash[:notice] = "Thank you for your submission..."
redirect_to root_path
else
flash[:error] = "There was a problem submitting your attachment."
render "new"
end
end
end
Attachment.rb
class Attachment < ActiveRecord::Base
def uploaded_file=(incoming_file)
self.filename = incoming_file.original_filename
self.content_type = incoming_file.content_type
self.data = incoming_file.read
end
def filename=(new_filename)
write_attributes("filename", sanitize_filename(new_filename))
end
private
def santize_filename(filename)
just_filename = File.basename(filename)
just_filename.gsub(/[^\w\.\-]/, '_')
end
end
视图/附件/ new.html.erb
<%= form_tag('create', multipart: true) do %>
<%= file_field_tag 'attachment' %>
<%= submit_tag "upload", class: 'btn btn-primary' %>
<% end %>
