Hi All,
Please help me ,I need to look into this issue asap, I need to change
the redmine functionality of uploading files to disk to upload them to
database. I tried suggestion on
http://dizzy.co.uk/ruby_on_rails/contents/store-file-uploads-in-database
but no luck , My form is multipart but still getting the error.
Please bare with me I am new to ruby and rails.
Here is the like for my redmine question
http://www.redmine.org/boards/2/topics/7737
I need to change Redmine functionality to upload files directly to
database and not to local filesystem. *
1. What I think is that I should add a field to "Attachments" table.*
I did this via this following migration
class AddFileToAttachments < ActiveRecord::Migration
def self.up
add_column :"attachments", :"file", :binary, :limit
=>10.megabytes
end end
def self.down
drop_column :"attachments", :"file"
end
2. Now I should change the model code to copy the file content into the
blob.
I updated attachment.rb , just added the line self.file @temp_file.read
as I need to read the content of file and put it into database.
def file=(incoming_file)
unless incoming_file.nil?
@temp_file = incoming_file
if @temp_file.size > 0
self.filename = sanitize_filename(@temp_file.original_filename)
self.disk_filename = Attachment.disk_filename(filename)
self.content_type = @temp_file.content_type.to_s.chomp
self.filesize = @temp_file.size
self.file = @temp_file.read
end
end
end
But After doing so I am getting the following error: Anybody please give
some direction
ndefined method `original_filename'' for #<String:0x8c09038>
