Rails - Export records to downloadable excel file using axlsx gem (Keep MVC)

Question

I have installed the axlsx gem successfully from https://github.com/randym/axlsx Here is my controller code that I used to create an excel file through this gem.

But nothing happen with this code instead it shows me an error uninitialized mime

class Coaches::PaymentsController < ApplicationController    before_filter :authenticate_coach!    # List all the payments   def index     if !params[:sort].blank?       @payments = Payment.includes(:member).paginate(:page => params[:page], :order => sort_column + " " + sort_direction)     else       @payments = Payment.includes(:member).paginate(:page => params[:page], :order=>'id desc')     end     respond_to do |format|       format.html       # Change format to xlsx       format.xlsx       format.json { render json: @payments }     end   end end 

Secondly,I try with this code:

wb = xlsx_package.workbook wb.add_worksheet(name: "Buttons") do |sheet|   @buttons.each do |button|     sheet.add_row [button.name, button.category, button.price]   end end 

But unfortunately, it does not work. Can anyone tell me only hint not a solution to do my task?

I have tried third times as per suggestion:

   def index     if !params[:sort].blank?       @payments = Payment.includes(:member).paginate(:page => params[:page], :order => sort_column + " " + sort_direction)     else       @payments = Payment.includes(:member).paginate(:page => params[:page], :order=>'id desc')     end     respond_to do |format|       format.xlsx do         p = Axlsx::Package.new         wb = p.workbook         wb.add_worksheet(name: "Your worksheet name") do |sheet|           sheet.add_row ["First Column", "Second", "Third"]           sheet.add_row [1, 2, 3]           sheet.add_row [' preserving whitespace']         end         send_data p.to_stream.read, type: "application/xlsx", filename: "filename.xlsx"       end     end   end 

It thrown me http 406 error

Answer 1

Try using axlsx_rails Gem with template. In my case i used below configuration to make it work. and also a link with extension .xlsx to render it in xlsx format.

GEM FILE

gem 'axlsx', '~> 2.0' gem "axlsx_rails" 

controller file- payments_controller.rb

def download     @payments = Payment.all     respond_to do |format|         format.xlsx {render xlsx: 'download',filename: "payments.xlsx"}     end end 

View file- download.xlsx.axlsx

wb = xlsx_package.workbook wb.add_worksheet(name: "Payments") do |sheet|     sheet.add_row ["ID", "Notes","Amount($)","Deposit Date"]     @payments.each do |payment|         sheet.add_row [payment.id, payment.notes,payment.amount,payment.date_deposite]     end end
