Hi,
being still quite new to Rails, Ruby and this whole cool programming stuff (and not having done my homework in studiying the basics) this problem is probably quite simple. But it still bugs me out as I have to finish the site. Like last month.
I've used Advanced Rails Recipes (http://media.pragprog.com/titles/fr_arr/upload_images_with_thumbnails.pdf) to upload images for my products. Now the customer wants two more categories - with other sizes for the attachment. I managed to differentiate it when uploading the images in the first place. But changing them doesn't work. I simply don't now how to tell has_attachment which sizes are to be used.
Here's what I have so far (I know, it's ugly as hell, but it just has to work. Good is saved for my second project.):
product_service.rb
def update_attributes(product_attributes, mugshot) @product.attributes = product_attributes unless mugshot.blank? @mugshot.update_attributes(:uploaded_data => mugshot) end save end
mugshot.rb
class Mugshot < ActiveRecord::Base
belongs_to :product
last_product = Product.find(:last)
if(last_product.category_id == 1)
has_attachment :content_type => :image, :storage => :file_system, :max_size => 500.kilobytes, :resize_to => '308x364>', :thumbnails => { :cart => '55x65>', :carousel => '144x170>' }
else
has_attachment :content_type => :image, :storage => :file_system, :max_size => 500.kilobytes, :resize_to => '308x225>', :thumbnails => { :cart => '64x47>', :carousel => '122x89>' }
end
validates_as_attachment
end
I use last_product (which is probably pretty ugly) to determine, which category the product has, that was just created. My question: How can I pass a variable to mugshot.rb when updating my product.
Thanks in advance for suggestions. And yes, when I finish this project, I will start with DRY, MVC, RESTfulness and all the things that make so much sense in Rails.
