Check required variables

    raise 'Please enter all required parameters' if settings.client_id.empty? or settings.private_key.empty?

get document by file GUID

    case settings.source
    when 'guid'

Create instance of File

        file = GroupDocs::Storage::File.new({:guid => settings.file_id})
    when 'local'

Construct path

        file_path = "#{Dir.tmpdir}/#{params[:file][:filename]}"

Open file

        File.open(file_path, 'wb') { |f| f.write(params[:file][:tempfile].read) }

Make a request to API using client_id and private_key

        file = GroupDocs::Storage::File.upload!(file_path, {}, {:client_id => settings.client_id, :private_key => settings.private_key})
    when 'url'

Upload file from defined url

    datasource = GroupDocs::DataSource.new

Get arry of document's fields

    enteredData = {"sex" => settings.sex, "name" => settings.name, "age"=> settings.age, "sunrise" => settings.sunrise}

Create Field instance and fill the fields

    datasource.fields = enteredData.map { |key, value| GroupDocs::DataSource::Field.new(name: key, type: :text, values: Array.new() << value) }

Adds datasource.

    datasource.add!({:client_id => settings.client_id, :private_key => settings.private_key})

Creates new job to merge datasource into document.

    job = document.datasource!(datasource, {:new_type => settings.type}, {:client_id => settings.client_id, :private_key => settings.private_key})
    sleep 10 # wait for merge and convert

Returns an hash of input and output documents associated to job.

    document = job.documents!({:client_id => settings.client_id, :private_key => settings.private_key})

Download file

    document[:inputs][0].outputs[0].download!(downloads_path, {:client_id => settings.client_id, :private_key => settings.private_key})

Set converted document GUID
