Rails unknown format when file is uploaded by paperclip

Question

i am working on rails with paperclip gem and trying to upload a document ,

this is my html form

<div style="background: #ee6e73; width: 100%;"><h3 class="center-align" style="color: #fff;font-weight: 600 !important;">Upload Resume</h3></div>
<div class="modal-content">
  <%= form_for(Document.new, :url => resume_upload_individual_profile_path, remote: true, :html => {:multipart => true } ) do |f| %>
      <%= hidden_field_tag :authenticity_token, form_authenticity_token %>
      <%= hidden_field_tag :profile_id, @profile.id %>
      <div class="row">

        <div class="file-field input-field">
          <div class="btn">
            <span>Choose Document</span>
            <i class="material-icons prefix">input</i>
            <%= file_field_tag :document %>
          </div>
          <div class="file-path-wrapper">
            <input class="file-path validate" type="text">
          </div>
        </div>

      </div>

      </div>
      <div class="modal-footer">
        <button type="submit" style="float: left;margin-top: 0%;" class="waves-effect waves-light btn-large  "><i class="material-icons left">cloud</i>Submit</button>
        <a href="#!" class=" modal-action modal-close waves-effect waves-green btn-flat">Close</a>
      </div>
  <% end %>

and my controller action is

def resume_upload

    p params
    @resume = Document.create(resume_params)
    if @resume.save
      @message = 'Your Resume has been successfully uploaded'
      # redirect_to individual_profile_path(individual_id: current_individual.id)
    else

      # redirect_to individual_profile_path(individual_id: current_individual.id)
      @message = find_error(@resume)
    end
    respond_to do |format|
      format.js
    end

  end

and my model has

has_attached_file :document
  validates_presence_of :document
  validates_attachment_content_type :document, :content_type => ["application/pdf","application/vnd.ms-excel",
                                                                 "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
                                                                 "application/msword",
                                                                 "application/vnd.openxmlformats-officedocument.wordprocessingml.document",
                                                                 "text/plain"]

the issue i am facing is when i select a file and try to uplaod , i get an error ActionController::UnknownFormat

but I am not facing this issue when i submit the form without selecting the file , i am able to successfully go into the js.erb file.

In order to get it working with these files you need to add the mime types to the server config. In Rails this is done in config/initializers/mime_types.rb

Mime::Type.register "application/vnd.openxmlformats-officedocument.wordprocessingml.document", :docx

This will help:- What is a correct mime type for docx, pptx etc?

Then maybe you should post more logs to help us understand better. – Malware Skiddie Feb 22 '16 at 08:09
Rails has several Mime:Type that are built in. by looking at your logs it's clearly a issue of mime type, your filename states card.png but you don't have validates attachment for images :- validates_attachment_content_type :avatar, content_type: /\Aimage\/.*\Z/ . If it solved your query then mark answer as accepted. – Malware Skiddie Feb 22 '16 at 10:01
but i dont want .png to be uploaded . i only want pdf and docs to be uploaded . i tried to upload that .png file so that i could get the validation error mesage – user4965201 Feb 22 '16 at 10:06
