Rails : saving and displaying images from database

Here is the logic to save images into blob and displaying those saved images..

Here is my database table:

| Field | Type
----------------------------------------------------------
| id | int(11)
| upload_file_name | varchar(255)
| upload_content_type | varchar(255)
| upload_file_size | int(11)
| created_at | datetime
| updated_at | datetime
| data | mediumblob
-----------------------------------------------------------

In VIEW:

<%= f.file_field :image_file, :value => "Select a file"%>

In CONTROLLER:

@uploadimages = UploadImage.new

@uploadimages.upload_file_name = params[:image_attributes][:image_file2].original_filename

@uploadimages.upload_content_type = params[:image_attributes][:image_file2].content_type

@uploadimages.upload_file_size = params[:image_attributes][:image_file2].size

@uploadimages.data = params[:image_attributes][:image_file2].read

@uploadimages.save

This will save the image into the database.

-------------------------------

Here is the code to display the saved image from the database:

In CONTROLLER:

def show_image

@image = UploadImage.find(params[:id])

send_data @image.data, :type => 'image/png', :disposition => 'inline'

end

In VIEW:

<%= image_tag url_for(:action => 'show_image', :id => images.id), :size => "300x200") %>

This will display the image!!
