activerecord-postgis-adapter：＃ <ArgumentError: wrong number of arguments (3 for 4)>

Question

问题描述

我正在尝试将由前同事开发的现有Ruby on Rails应用程序（Ruby 2.3.3p222，Rails 5.0.0.1）迁移到JRuby。 使用上述Ruby版本，该应用程序运行无任何问题。 您可以在附录中找到原始的Gemfile，即Gemfile Ruby 。

由于我是Ruby的新手，也不知道到底出了什么问题，因此我提供了到目前为止所做的所有更改（请参见附录中的Gemfile JRuby以获取生成的Gemfile），以将应用程序迁移到JRuby。

1.更换gem 'pg'

我将gem 'pg', '~> 0.21.0'为

gem 'pg', '0.21.0', :platform => :jruby, :git => 'git://github.com/headius/jruby-pg.git', :branch => :master

按照jruby-pg的Github页面上的指示。 运行bundle install ，我启动了显示错误的应用程序：

LoadError: no such file to load -- active_record/connection_adapters/jdbcpostgresql_adapter

2. gem 'activerecord-postgis-adapter'

为了摆脱上一个错误，我在gem 'activerecord-postgis-adapter'了以下内容：

gem 'activerecord-jdbcpostgresql-adapter', '~> 1.3.9'
gem 'ffi-geos'

如activerecord-postgis-adapter的Github页面所建议。 同样，在bundler install并运行bundler install之后，出现错误：

Bundler::GemRequireError: There was an error while trying to load the gem 'activerecord-postgis-adapter'.
Gem Load Error is: uninitialized constant ActiveRecord::ConnectionAdapters::Column::Format

解决方法

我试图按照这篇文章中给出的提示，将gem 'activerecord-jdbcpostgresql-adapter行替换为

gem 'activerecord-jdbcpostgresql-adapter', :git => "git://github.com/jruby/activerecord-jdbc-adapter.git",
:branch => "50-stable", :platform => :jruby

由于以下错误，我删除了gem ffi-geos ，错误消失了：

最后，我可以运行该应用程序，但是，发送POST请求将返回以下错误

我只能在activerecord-jdbc-adapter找到此问题，但未说明任何解决方案。 由于我没有计划如何进行操作，因此您对错误原因有任何想法吗？ 非常感谢！

Answer 1

该问题与gem activerecord-jdbc-adapter ，可以在问题＃891中解决。 由于所有更改都是在分支50-stable ，因此无需更改Gemfile。 该应用程序现在在JRuby中运行：-)
