Question

我已成功从https://github.com/randym/axlsx安装了axlsx gem 这是我用来通过这个gem创建excel文件的控制器代码。

但这个代码没有任何反应，而是显示了一个错误未初始化的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

其次，我尝试使用此代码：

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

但不幸的是，它不起作用。任何人都可以告诉我只是暗示不是解决方案来完成我的任务吗？

我按照建议尝试了第三次：

   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

它抛出了我的http 406错误

Answer 1

尝试将axlsx_rails Gem与模板一起使用。在我的情况下，我使用下面的配置使其工作。以及扩展名为.xlsx的链接，以xlsx格式呈现。

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

查看文件 - 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

Answer 2

要防止未初始化的mime类型错误，请添加以下文件：

# config/initializers/mime_types.rb

Mime::Type.register "application/xlsx", :xlsx

以下是如何下载xlsx文件的简短示例：

format.xlsx do
  p = Axlsx::Package.new
  wb = p.workbook
  wb.add_worksheet(name: "Your worksheet name") do |sheet|
    # Add your stuff
  end
  send_data p.to_stream.read, type: "application/xlsx", filename: "filename.xlsx"
end

Answer 3

请将render false设置为HTML并避免使用JSON而不是使用XLS，并且对于跟踪，您可以看到已启动rails的终端。

Answer 4

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

Answer 5

我使用宝石。

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

但这些宝石出现了错误。当我删除＆＃39; rubyzip＆＃39;来自Gemfile.lock的gem，然后bundle install问题已经解决了。感谢。
