I've got a Lead model which is splited by lead_status param on products and offers. Only leads with product status should contain images and offers should not. I've migrated attached product_image table to schema and tried to set a default image only for products. Like this:

class Lead < ApplicationRecord


has_attached_file :product_image, styles: small: "150x150>", default: "350x350"
validates_attachment_content_type :product_image, content_type: /Aimage/.*z/

before_save :product_image_default_url

 def product_image_default_url
 if self.lead_status == "product" && self.product_image.url.nil?
 self.product_image.url = "/images/:style/default_user_avatar.png"
 end
end

1. Every time when I save a new lead without uploaded image I get "/product_images/original/missing.png" as a default url. No matter which status it has.


2. Model doesn't recognize new leads by it's status

How can I change that? Force my Lead model to save a default image url according to a "product" status and ignore all those with "offer" status?

My rails version is 5.2.1 and paperclip 6.0.0

Try with following,

has_attached_file 
 :product_image, 
 styles: small: "150x150>", default: "350x350",
 default_url: ":style/default_user_avatar.png"

 # app/assets/images/medium/default_user_avatar.png
 # app/assets/images/thumbs/default_user_avatar.png

Existing method is,

def default_url
 if @attachment_options[:default_url].respond_to?(:call)
 @attachment_options[:default_url].call(@attachment)
 elsif @attachment_options[:default_url].is_a?(Symbol)
 @attachment.instance.send(@attachment_options[:default_url])
 else
 @attachment_options[:default_url]
 end
end

In initializer, Provide monkey patch for following,

require 'uri'
require 'active_support/core_ext/module/delegation'

module Paperclip
 class UrlGenerator

 def default_url
 if @attachment.instance.lead_status == 'product'
 default_url = attachment_options[:default_url]
 else
 default_url = # provide another missing default_url
 end 
 if default_url.respond_to?(:call)
 default_url.call(@attachment)
 elsif default_url.is_a?(Symbol)
 @attachment.instance.send(default_url)
 else
 default_url
 end
 end

 end
end

Update as per cases
