Rails carrierwave and minimagick allow landscape image only

Question

Is it way to validate image orientation on image upload? I want that user can upload only landscape image.

Thanks

Answer 1

mount_uploader :photo, PhotoUploader

validate :check_landscape

def check_landscape
  if photo.width<photo.height
     errors.add :photo, "is not a landscape." 
     puts "Error ! not a Landscape Image"
  else if photo.width>photo.height
     puts " Landscape Image"
  end
  end
end

if you are looking for active_storage has_many_attached

has_many_attached :images


validate: active_storage_many_images

 def active_storage_many_images
    images.each do |image|

    image.blob.analyze unless image.blob.analyzed?
    width = image.blob.metadata[:width]
    height = image.blob.metadata[:height]

    if width<height
      errors.add :image, "Additional images are not landscape"
      puts "ACTIVE STORAGE IMAGE ERROR !!"
    end
  end
 end
