Error message

errors.messages.min_height_error

What it means

Raised as CarrierWave::IntegrityError when check_dimensions! sees an image shorter than the lower bound of height_range (message errors.messages.min_height_error, bound formatted via number_to_delimited). Same mechanics as the width checks: base version only, requires MiniMagick/RMagick/Vips for the height method, runs while the file is cached.

Solutions

1. Lower the height_range minimum to match real content (or remove the lower bound: height_range nil..2000)
2. Show the required minimum dimensions in the upload UI and validate with a client-side check (e.g. HTML/JS reading naturalHeight)
3. Rescue CarrierWave::IntegrityError and attach a specific 'image must be at least X px tall' validation message

Example fix

# before
class CoverUploader < CarrierWave::Uploader::Base
  include CarrierWave::MiniMagick
  height_range 600..2000 # 1200x200 image -> IntegrityError min_height_error
end

# after
class CoverUploader < CarrierWave::Uploader::Base
  include CarrierWave::MiniMagick
  height_range 150..2000
end

require 'fastimage'

MIN_H = 600
_h, h = nil, FastImage.size(params[:image].path)&.last
return render_error(:too_short) if h && h < MIN_H

def within_height_range?(path, range)
  _, h = FastImage.size(path)
  !h.nil? && (range.begin.nil? || h >= range.begin) && (range.end.nil? || h <= range.end)
end

begin
  record.save!
rescue CarrierWave::IntegrityError => e
  record.errors.add(:image, :dimensions_invalid, message: e.message)
  render :new
end

When it happens

Trigger: Declaring height_range 600..2000 and uploading a 300px-tall banner or wide-but-short strip image (e.g. 1200x200).

Common situations: Banners/covers with hard height minimums rejecting legitimately short artwork; UI copy not telling users the minimum; cropping tools allowing crops below the configured floor.
