Is it possible to import nested attributes containing remote urls?

[imtiaz-emu]

I'm trying to create records from a csv file. Each row of the CSV file will be a new record.

def import
  ads = []
  CSV.foreach(file.path, headers: true, encoding: encoding) do |row|
      ad = Ad.new
      ad.title = row['title'] || ''
      ad.description = row['description'] || ''
      
      # Ad has_one: variant
      ad.variant_attributes = initialize_ad_variant(row).attributes
      
      ads << ad
  end
  Ad.import(ads, recursive: true) # I'm using postgres  
end

def initialize_ad_variant(row)
     variant = Variant.new
     # inside CSV I have a column called 'custom_image_url', which contains an image url from where we need to save the image. 
     # 'custom_image' is the field name in variant table. I'm using carrierwave.
     variant.remote_custom_image_url = row['custom_image_url']
     variant.custom_text = row['custom_text']
     return variant
end

The above code inserts Ads with associated variants. But seems like the images are not uploaded inside the variant table. Only the custom_text is inserted.
Is there any way to bulk upload nested attributes like this; where the images will be uploaded from remote url?

I don't think so at this time. Are you using ActiveStorage? This might be a duplicate of issue #661.

Got it. No, I'm not using ActiveStorage.

Without knowing more of the internals of how the remote images are loading it's hard to give any suggestions. I would say try to find out if there is some type of call you make on each variant to manually load the image before importing.
