[英]ReporteController#opcionales is missing a template for this request format and variant. request.formats: [“application/pdf”] request.variant: []
[英]ModelsController#index is missing a template for this request format and variant. request.formats: [“application/xlsx”] request.variant: []
希望你做得很好。 我嚴格按照本手冊創建了一個新應用程序,並嘗試使用axlsx_rails Gem導出excel文件。 這本手冊看起來還不錯,但是當我單擊line_to標記時,會彈出此錯誤
ProductsController#index is missing a template for this request format and variant. request.formats: ["application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"] request.variant: []
和這個:
raise ActionController::UnknownFormat, message
我猜這個錯誤與我的參數有關。 我正在使用Rails 5有什么想法嗎? 太感謝了 :)
編輯:這是我的控制器:
def index
@products = Product.order('created_at DESC')
respond_to do |format|
format.html
format.xlsx {
response.headers['Content-Disposition'] = 'attachment; filename="all_products.xlsx"'
}
end
end
查看index.html.erb
<%= link_to 'Download as .xlsx', products_path(format: :xlsx) %>
查看index.xlsx.axlsx
wb = xlsx_package.workbook
wb.add_worksheet(name: "Products") do |sheet|
@products.each do |product|
sheet.add_row [product.title, product.price]
end
end
這是控制器的解決方案:
def export_to_excel
@tests = Test.all
respond_to do |format|
format.html
format.xlsx {
response.headers['Content-Disposition'] = 'attachment; filename="official_letters.xlsx"'
}
end
end
這是視圖/ ... export_to_excel.xlsx.axlsx
wb = xlsx_package.workbook
wb.add_worksheet(name: "tests") do |sheet|
@tests.each do |test|
sheet.add_row [test.title, test.price]
end
