Cara mengupgrade plugin redmine ke rails 5, alias_method_chain sudah tidak digunakan lagi sekarang

Apakah ini terkait dengan plugin ini?

Jika ya, inilah cara saya melakukannya:

• Di file init.rb, ubah ini:

RedmineApp::Application.config.after_initialize do
  ApplicationHelper.send(:include, GemAvatarPlugin::ApplicationAvatarPatch)
end

Untuk ini:

RedmineApp::Application.config.after_initialize do
  ApplicationHelper.prepend(GemAvatarPlugin::ApplicationAvatarPatch)
end

• Di lib/application_helper_gemavatar_patch.rb, ubah ini:

require 'application_helper'

module GemAvatarPlugin
  module ApplicationAvatarPatch

    def self.included(base)
      base.send(:include, InstanceMethods)
      base.class_eval do
        alias_method_chain :avatar, :gemavatar
      end
    end

    module InstanceMethods

      def avatar_with_gemavatar(user, options = { })
        # method content omitted for clarity
      end

    end
  end
end

untuk ini:

module GemAvatarPlugin
  module ApplicationAvatarPatch

    def avatar(user, options = { })
      # method content omitted for clarity
    end

  end
end

Saya akan menghapus require 'application_helper' karena saya tidak mengerti mengapa itu diperlukan

Saya juga mencoba memperbarui plugin ini. Saya menggunakan https://github.com/alexandermeindl/redmine_local_avatars sebagai contoh.

Di init.rb ubah ini:

RedmineApp::Application.config.after_initialize do
  ApplicationHelper.send(:include, GemAvatarPlugin::ApplicationAvatarPatch)
end

untuk ini:

RedmineApp::Application.config.after_initialize do    
  ApplicationHelper.include ApplicationAvatarPatch
end

lib/application_helper_gemavatar_patch.rb yang ditambal, terlihat seperti ini:

module ApplicationAvatarPatch    
def self.included(base)
    base.send(:include, InstanceMethods)

    base.class_eval do
        alias_method :avatar_without_gemavatar, :avatar
        alias_method :avatar, :avatar_with_gemavatar
    end
end

module InstanceMethods
    def avatar_with_gemavatar(user, options = { })
        if Setting.gravatar_enabled? && user.is_a?(User)
            options.merge!({:ssl => (defined?(request) && request.ssl?), :default => Setting.gravatar_default})
            options[:size] = "64" unless options[:size]
            avatar_url = url_for :controller => :pictures, :action => :delete, :user_id => user
            return "<img class=\"gravatar\" width=\"#{options[:size]}\" height=\"#{options[:size]}\" src=\"#{avatar_url}\" alt=\"Gemavatar text\" />".html_safe
        else
            avatar_without_gemavatar(user, options)
        end
    end
end
end

Saya mencobanya hanya dengan Redmine 4.0.3 tetapi sepertinya berhasil. Namun ada peringatan di log server web:

127.0.0.1 - - [06/Mar/2020:20:58:23 CET] "GET /gemavatar/164 HTTP/1.1" 200 3545

[2020-03-06 20:58:23] WARN  Could not determine content-length of response body. Set content-length of the response or set Response#chunked = true

Pada plugin redmine_local_avatars terdapat patch yang berbeda untuk Redmine 4.1.

Pembaruan: Saya menyiapkan repositori github dengan perubahan: https://github.com/pentekl/redmine_gemavatar

Anda dapat menggunakan alias_method alih-alih alias_method_chain, tetapi saya sedang mencari solusi seperti prepend

                alias_method :avatar_without_gemavatar, :avatar
                alias_method :avatar, :avatar_with_gemavatar

UPD: Namun ini memberikan peringatan:

UPD: Seperti ste26054 disebutkan dalam jawabannya dan berkomentar di sini require 'application_helper' dapat dihapus untuk mencegah peringatan, karena sudah termasuk dalam inti.
