ruby-on-rails - Rails ActionController 未知格式

Question

我正在尝试渲染一个 xlsx 文件。但我不断收到 406/UnknowFormat。我已经完成了正确的设置，也许我遗漏了什么？

Rails 4.2 应用

gem 'axlsx'
gem "axlsx_rails"
gem 'zip-zip'

配置/初始化程序/mime

Mime::Type.register "应用程序/xlsx", :xlsx

Controller

respond_to do |format|
      format.xlsx { render xlsx: "create", template: "api/reports/create" }
end

views/api/reports/create.xlsx.axlsx

wb = xlsx_package.workbook
wb.add_worksheet(name: "Reports") do |sheet|
  sheet.add_row [@report_name]
end

Answer 1

对我来说，在 Rails 4.2 中，我必须指定完整的模板文件名，包括扩展名。根据axlsx_rails docs Rails 4.2 中的语法有所不同。这是对我有用的:

some_controller.rb

def create_report
  render "template_path/report.xlsx.axlsx"
end

template_path/report.xlsx.axlsx

wb = xlsx_package.workbook
wb.add_worksheet(:name => "Basic Worksheet") do |sheet|
  sheet.add_row ["First Column", "Second", "Third"]
end
