Ruby on rails 避免重复使用相同代码的新类

我有一个类在Jira board中创建了一个问题。我想在5种不同的场景中使用它，但唯一不同的是必填字段，如

摘要

，

说明

，和

发行类型

。如何处理这样的场景，以避免创建几个具有90%相同内容的类

这是本课程的主要内容：

module Jira
  class TicketCreator
    def call
      issue = client.Issue.build
      issue.save(required_fields)
    end

    private

    def client
      @client ||= Jira::JiraConnection.new.call
    end

    def required_fields
       #data from below examples
    end
  end
end

以下是我想使用的必填字段的场景，具体取决于webhook信息：

def required_fields
  {
    'fields' => {
      'summary' => 'Create new repo <github_repo> for <Github user>',
      'description' => 'This is an automatic confirmation of creating new PRIVATE repo
                      - <github_repo> for <Github user>',
      'project' => { 'key' => 'TEST' },
      'issuetype' => { 'id' => '12580' },
      'customfield_15100' => 'None'
    }
  }
end

def required_fields
  {
    'fields' => {
      'summary' => 'Add <Github user> collaborator to <github_repo>',
      'description' => 'This is an automatic ticket confirmation of user added',
      'project' => { 'key' => 'TEST' },
      'issuetype' => { 'id' => '12580' }, # nonautoresolved
      'customfield_15100' => 'None'
    }
  }
end

def required_fields
  {
    'fields' => {
      'summary' => 'Recheck <Github user> deleted <github_repo>',
      'description' => 'This is an automatic ticket confirmation of delete repo <github_repo>',
      'project' => { 'key' => 'TEST' }, # change to project_key
      'issuetype' => { 'id' => '12579' }, # autoresolved
      'customfield_15100' => 'None'
    }
  }
end

def必填_字段
{
“字段”=>{
'摘要'=>'为''，
'description'=>'这是创建新私人回购的自动确认
-对于'，
'project'=>{'key'=>'TEST'}，
'issuetype'=>{'id'=>'12580'}，
“customfield_15100”=>“无”
}
}
结束
def必填_字段
{
“字段”=>{
'摘要'=>'将协作者添加到'，
'description'=>'这是用户添加的自动票证确认'，
'project'=>{'key'=>'TEST'}，
'issuetype'=>{'id'=>'12580'}，#非自动解析
“customfield_15100”=>“无”
}
}
结束
def必填_字段
{
“字段”=>{
'摘要'=>'重新检查已删除'，
'description'=>'这是删除回购的自动票据确认'，
'project'=>{'key'=>'TEST'}，#更改为project_key
'issuetype'=>{'id'=>'12579'}，#自动解决
“customfield_15100”=>“无”
}
}
结束

如何避免创建新类，其中唯一的区别是此

必填\u字段

方法？

您可以将关键字参数与合并默认选项和传递的选项：

module Jira
   class TicketCreator
     # Do setup at initializion instead
     def initialize
       # FIXME - style violation - this should be client.issue.build 
       @issue = client.Issue.build 
     end

     def call(**options)
       @issue.save(required_fields(options))
     end

     # Takes care of initializion so that you can call 
     # Jira::TicketCreator.call - you can DRY this though inheritance or mixins
     def self.call(**options)
       new.call(options)
     end

     private

     def client 
       @client ||= Jira::JiraConnection.new.call
     end

     def required_fields(**options)
       {
         'fields' => {
           'summary' => 'Recheck <Github user> deleted <github_repo>',
           'description' => 'This is an automatic ticket confirmation of delete repo <github_repo>',
           'project' => { 'key' => 'SUP' }, # change to project_key
           'issuetype' => { 'id' => '12579' }, # autoresolved
           'customfield_15100' => 'None'
         }.reverse_merge(options.deep_stringify_keys)
       }
     end
   end
 end

你能将所需的_字段发送给你的班级吗

# TicketCreator.new(required_fields).call
module Jira
  class TicketCreator
    def initialize(required_fields)
      @required_fields = required_fields
    end

    def call
      issue = client.Issue.build
      issue.save(@required_fields)
    end

    private

    def client
      @client ||= Jira::JiraConnection.new.call
    end
  end
end

如果您希望为每一个都使用一个命令，可以使用继承：

module Jira
  class Base
    def call
      issue = client.Issue.build
      issue.save(required_fields)
    end

    private

    def client
      @client ||= Jira::JiraConnection.new.call
    end

    def required_fields; end
  end
end

module Jira
  class CreateRepo < Base
    def required_fields
      {
        'fields' => {
          'summary' => 'Create new repo <github_repo> for <Github user>',
          'description' => 'This is an automatic confirmation of creating new PRIVATE repo
                      - <github_repo> for <Github user>',
          'project' => { 'key' => 'TEST' },
          'issuetype' => { 'id' => '12580' },
          'customfield_15100' => 'None'
        }
      }
    end
  end
end

module Jira
  class AddCollaborator < Base
    def required_fields
     {
      # data
     }
    end
  end
end
