macOS Big Sur 11.4 系统 env: ruby.exe: No such file or directory 问题

zhg — Fri, 09 Jul 2021 09:56:03 +0800

各位大神 MAC 系统执行 rails s 时直接返回 env: ruby.exe: No such file or directory 错误，ruby.exe 不应该是 windows 系统的应用程序嘛？在 mac 系统为什么会出现这个报错; 我同事的 macOS 是 10.14.3 版本的 bundle 完成之后可以正常执行。

Savon SOAP 返回的 PDF 数据流下载后打不开

zhg — Mon, 21 Aug 2017 13:58:38 +0800

现在的项目中需要通过标准 SOAP 协议从接口获取数据，获取的数据应该是 PDF 二进制流数据，但是打印出来的文件无法打开！报错信息为文件已损坏或者使用了“预览”无法识别的文件格式。

我是使用 savon 来传递数据获取返回值值的。

返回值：

'Label' 标签后面应该是二进制流的，现在直接打印出来的 PDF 文件无法打开。

ransacks 关联搜索排序报错

zhg — Thu, 20 Apr 2017 18:55:24 +0800

我现在使用 ransacks 来进行搜索操作

@q = Order.ransack(params[:q].merge(shipping_print_status_eq: Shipping::PrintStatus::PRINTING))

@orders = @q.result(distinct: true)

@orders = @orders.includes(:shipping).order("shippings.print_at DESC NULLS LAST")

error

ActiveRecord::StatementInvalid - PG::InvalidColumnReference: ERROR:  for SELECT DISTINCT, ORDER BY expressions must appear in select list

请问不使用 .to_a.uniq 这种方法怎么来解决
