validates attachment filename throws error.

[chitrank-samaiya]

Hi Guys, I am trying to implement validation for filename, but it is giving undefined method 'before_file_name_post_process'.

Here is my model code:

    class JobSeeker
        include Mongoid::Document
        include Mongoid::Timestamps
        include Mongoid::Paperclip
        include SimpleEnum::Mongoid
        include Mongoid::Search

         # attributes
         field :first_name, type: String
         field :last_name, type: String
         field :current_title, type: String
         field :summary, type: String
         field :phone, type: String
         field :zipcode, type: String
         field :resume_data, type: String
         field :applied_jobs, type: Array, default: []

        #paperclip upload
        has_mongoid_attached_file :resume,
        :path => ":rails_root/public/system/:attachment/:id/:style/:filename",
        :url => "/system/:attachment/:id/:style/:filename"
        validates_attachment_file_name :resume_file_name, :matches => [/pdf\Z/]

        search_in :resume_data, :skill => [:primary, :secondary]

        #callbacks
        after_save :parse_attachment

        def parse_attachment
            if self.resume.exists?
                file = self.resume.path
                    if self.resume_content_type == 'application/pdf'
                          reader = PDF::Reader.new(file)
                          data = reader.pages.each do |page|
                          page.text
                        end
                        data = data.join("\n")
                    else  
                        MSWordDoc::Extractor.load(file) do |doc|
                          data = doc.document
                        end
                    end
                data = data.squeeze rescue nil
                self.set(resume_data: data)
            end  
        end 
    end

Error:

Hi @chitrank-samaiya. Is this still an issue for you? Can you upgrade to 4.2.1 and see if the problem persists? Thanks for your input.

Thanks @tute. This is no more issue for me.
