请各位帮帮我
如何在插件中使用我的验证器？

我在插件中添加了一个文件

lib/validators/plugin_ldap_setting_validator.rb

在 settings.yml 中使用

  forum_ldap_validation:
    default: 'system'
    validator: 'PluginLdapSettingValidator'

在 plugin.rb 中加载文件

load File.expand_path('../lib/validators/plugin_ldap_setting_validator.rb', __FILE__)

出现错误

那里将 key 设为 ‘validator’

甚至这样的示例也能生效：

plugins:
  my_custom_username_validation:
    default: 'system'
    validator: 'UsernameSettingValidator'
3

将文件放置在 discourse/lib/validators/ldap_setting_validator.rb 后，问题已解决：

 forum_ldap_validation:
    default: 'system'
    validator: 'LdapSettingValidator'

如何使该代码在插件中生效？

太好了，成功了

plugin.rb 中的代码

def forum_require(path)
  require Rails.root.join('plugins', 'forum', 'app', path).to_s
end

after_initialize do

  forum_require 'lib/ldap_setting_validator'
//代码
end

ldap_setting_validator.rb → 路径 → myplugin/app/lib/ldap_setting_validator.rb

感谢提供的示例 → babble/plugin.rb at master · gdpelican/babble · GitHub

我昨天一直在寻找如何操作的示例。我在 Discourse 仓库中找到的示例位于此处：https://github.com/discourse/discourse-chat-integration。你会看到，在该插件的 plugin.rb 文件中，验证器类是通过以下命令引入的：

require_relative "lib/discourse_chat/provider/slack/slack_enabled_setting_validator"

为了让 Discourse 找到该验证器，它需要在调用 after_initialize 之前被包含进来。
