如何计算文件文档 ruby gem 中的页数？

Question

I need to count the number of pages in a docs file, There are many pages in a docs file, I want to count the number of pages in it to facilitate input Currently I only count the number of pages if it is a pdf file

Do you know any technology or gem that can solve it?

I believe you can use the docsplit gem. You can find the documentation here .

Gemfile:

gem docsplit

Then you should be able to retrieve the number of pages with:

Docsplit.extract_length('path/to/stooges.docx')

Or you could convert your document to PDF and return the number of pages with the method you already know. Using docsplit-paperclip-processor , find the documentation enter link description here .

Gemfile:

gem 'docsplit-paperclip-processor'

Then run bundle install . Then in your model:

class Document < ActiveRecord::Base

  has_attached_file :file,
                    :styles => {
                      :pdf => {
                        :format => "pdf",
                        :processors => [:docsplit_pdf]
                      }
                    }

end
