问题
Added an export-to-xlsx option with the axlsx and axlsx_rails gems to an existing Rails 4.2.0 app that uses Devise for authentication. Export to xlsx now works properly:
app/controllers/cases_controller.rb:
class CasesController < ApplicationController
def create
⋮
@public_fields = public_fields
respond_to do |format|
⋮
format.xlsx { render :xlsx => "create", :filename => "cases.xlsx" }
end
end
end
app/views/cases/create.xlsx.axlsx:
wb = xlsx_package.workbook
wb.add_worksheet(name: 'Cases') do |sheet|
sheet.add_row @public_fields
@cases.each do |kase|
sheet.add_row( @public_fields.map { |field| kase[field] } )
end
end
However, the previously working authentication stopped working. Accessing the Devise sign_in or sign_up routes, either by clicking the links or by navigating to prompts this error:
NoMethodError in Users::SessionsController#new undefined method `call' for ActionController::Responder:Class
Extracted source (around line #203):

I know that axlsx_rails patches ActionController::Responder. Has this change broken Devise?
回答1:
Noel (from the comments) was correct: I was using the wrong version of axlsx_rails with rails 4.2. I fixed this and it works perfectly.
