Hey guys i am trying to upload a file using the remotipart gem, so i got to the point where the files is submitted and i get the following in the console:

Parameters: {"utf8"=>"✓", "authenticity_token"=>"b3+vGGBgjaxZ5W7UhJIZfqK9vz7MsAi1ipeDrDV1vgo=", "commit"=>"Upload", "remotipart_submitted"=>"true", "X-Requested-With"=>"IFrame", "X-Http-Accept"=>"text/javascript, application/javascript, application/ecmascript, application/x-ecmascript, */*; q=0.01", "uploaded_file"=>{"uploaded_file"=>#<ActionDispatch::Http::UploadedFile:0xb5f72ac8 @tempfile=#<Tempfile:/tmp/RackMultipart20140306-2294-1ifwfm5>, @original_filename="INSTRUCTION.txt", @content_type="text/plain", @headers="Content-Disposition: form-data; name=\"uploaded_file[uploaded_file]\"; filename=\"INSTRUCTION.txt\"\r\nContent-Type: text/plain\r\n">}}

So i have the file, but i do not know how should i read it.. I do not want to store the file, i just want to read it. Also, out from the parameters, i can get the parameter "uploaded_file":

params[:uploaded_file]

But in this case, how can i get one of its contents? I mean if i want to get the value of @headers inside the uploaded_file parameter, how can i do that? Also for some reason the javascript file attached to the current action is not working, here is my view:

= form_for(:uploaded_file, :remote => true, :url => {:action => 'parseFile'}, :html => {:multipart=>true}, :authenticity_token => true) do |f|
                div class="browse"
                    span
                        | Choose file..

                    = f.file_field :uploaded_file

                    div id="file-status"
                        | You have not selected any files yet.

                    = f.submit :value => "Upload", :class => 'hidden'

And here is my controller:

    def parseFile
        :format == 'js'

        if params[:remotipart_submitted]
            respond_to do |format|
              format.js
            end
        end

        render :nothing => true
    end

The parseFile.js.erb has the following contents:

alert(1);

And it never gets invoked.. Any help will be superb!

Thanks in advance! {:
