save images using paperclip without view

[kashif ali]

I'm using Paperclip to save images from my current local app directory. I have used two models to save images. 

business.rb   

    class Business < ActiveRecord::Base

    # Associations

       has_attached_file :logo, :styles => {:thumb => "100x100>"}

       validates_attachment :logo,

                       :size => {:in => 1..1500.kilobytes}

    end

image.rb

    class Image < ActiveRecord::Base

       has_attached_file :data, :styles => { :thumb => '100x100>', :medium => '240x240>' }

    end

when i try to save image it is not working for me like below.

    Business.create(:logo => Image.first.url)

and i have this error

    Paperclip::AdapterRegistry::NoHandlerError: No handler found for "/system/images/data/000/000/177/medium/error.png"

while "Image.first.url" give me this path

       "/system/images/data/000/000/177/medium/error.png"

How i can do this?

Thanks

Why do you need 2 papeeclip fields? You could make a relation bewteen image and business

business.logo = image

I have association like this

     business.rb

       has_many :images

    image.rb

       belongs_to :business

so on my business new page user can upload many images. while on edit page all images against one business will be display and when user click on any image it becomes logo for business.

       so on edit action in controller

    def edit

      @business = Business.find(params[:id])

      @business.update_attribute(:logo ,@business.images.first.url)

 

   end

i have this error

 how i can save or update this image as logo.

Thanks

Maybe :logo is expecting a Paperclip object and you are passing a String.

Try:

@business.update_attribute(:logo ,@business.images.first)
