Buffered image to file in rails

Rails
1

Hi,

I was trying to integrate a scanner with my application. After a long
struggle i succeeded in integrating, Now i could see the captured image
in my browser, But now i need to upload that image in buffer to the file
system(Server Side) or to data base.

How to carry out this any suggestions?

Thanks,
Ratnavel.

Store Image in Database

~> ruby script/generate model picture

Migration

class CreatePicture < ActiveRecord::Migration
def self.up
create_table :global_configs do |t|
t.column :data, :blob
t.column :content, :string
end
end

def self.down
drop_table :kamars
end
end

~> rake db:migrate

VIEW # for FORM to Upload

<% form_tag ({:action => "upload_pict" }, {:multipart => true}) do

%>
<%= file_field “web”, “image” %>
<%= submit_tag “Upload” %>
<% end %>
<%= end_form_tag %>

CONTROLLER # store image into DB

class TeaPociController < ApplicationController

…

def upload_pict

if params[:web][‘image’].size > 1
@type_file =
File.extname(params[:web][‘image’].original_filename.gsub(/[^\w._-]/,“”))

#Check Image, Image should be Picture
if @type_file == “.jpeg” || @tipe_file == “.gif” || @tipe_file == “.bmp”
|| @tipe_file == “.jpg” || @tipe_file == “.png”

@picture = Picture.new

@picture.data = params[:web][‘image’].read
@picture.content = params[:web][‘image’].content_type.chomp

if @picture.save
flash[:notice] = “Image is stored in database successfully.”
end

else
flash[:notice] = “File is not an image.”
end

else
flash[:notice2] = “Image is empty.”
end

end

…

end

CONTROLLER

class TeaPociController < ApplicationController

…
def display_image
@real_picture = Picture.find(params[:id])
send_data(@real_picture.data,
:type => @real_picture.content,
:disposition => “inline”)
end

end

VIEW #DISPLAY IMAGE IN RHTML
