[英]How to upgrade redmine plugin to rails 5, alias_method_chain is deprecated now
Just started learning RoR, but in short period of time I need to add functionality similar to Loading images from LDAP (incompatible version) into our project.刚开始学习 RoR,但在短时间内我需要将类似于从 LDAP(不兼容版本)加载图像的功能添加到我们的项目中。 Project is abondoned, and I can't find any related info/docs, so I'm asking for help here.
项目被放弃,我找不到任何相关信息/文档,所以我在这里寻求帮助。 Solution, tutorial, anything could work.
解决方案、教程,任何东西都可以。
$ ruby bin/rake redmine:plugins RAILS_ENV="production"
rake aborted!
NoMethodError: undefined method `alias_method_chain' for ApplicationHelper:Module
Did you mean? alias_method
...
plugins\redmine_gemavatar\lib\application_helper_gemavatar_patch.rb :插件\redmine_gemavatar\lib\application_helper_gemavatar_patch.rb :
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 = { })
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}\" />".html_safe
else
''
end
end
end
end
end
I've found good article here How To Replace alias_method_chain , but I'm not quite sure how to apply prepend
style to redmine plugin's monkey patch.我在这里找到了很好的文章How To Replace alias_method_chain ,但我不太确定如何将
prepend
样式应用于 redmine 插件的猴子补丁。 Just can't get it work:/只是无法让它工作:/
Is this related to this plugin ?这与这个插件有关吗?
If so, here is how I would do it:如果是这样,我会这样做:
init.rb
file, change this:init.rb
文件中,更改此内容:RedmineApp::Application.config.after_initialize do
ApplicationHelper.send(:include, GemAvatarPlugin::ApplicationAvatarPatch)
end
To this:对此:
RedmineApp::Application.config.after_initialize do
ApplicationHelper.prepend(GemAvatarPlugin::ApplicationAvatarPatch)
end
lib/application_helper_gemavatar_patch.rb
, change this:lib/application_helper_gemavatar_patch.rb
中,更改此内容: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
to this:对此:
module GemAvatarPlugin
module ApplicationAvatarPatch
def avatar(user, options = { })
# method content omitted for clarity
end
end
end
I would remove the require 'application_helper'
because I don't see why it's needed我会删除
require 'application_helper'
因为我不明白为什么需要它
I also tried to update this plugin.我也尝试更新这个插件。 I used https://github.com/alexandermeindl/redmine_local_avatars as an example.
我以https://github.com/alexandermeindl/redmine_local_avatars为例。
In init.rb changed this:在 init.rb 中改变了这个:
RedmineApp::Application.config.after_initialize do
ApplicationHelper.send(:include, GemAvatarPlugin::ApplicationAvatarPatch)
end
to this:对此:
RedmineApp::Application.config.after_initialize do
ApplicationHelper.include ApplicationAvatarPatch
end
the patched lib/application_helper_gemavatar_patch.rb, looks like this:打补丁的 lib/application_helper_gemavatar_patch.rb 看起来像这样:
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
I tried it only with Redmine 4.0.3 but it seems to be working.我只在 Redmine 4.0.3 上尝试过,但它似乎可以正常工作。 However there are warnings in the webserver log:
但是网络服务器日志中有警告:
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
In the redmine_local_avatars plugin there was a different patch for Redmine 4.1.在 redmine_local_avatars 插件中有一个针对 Redmine 4.1 的不同补丁。
Update: I set a up a github repository with the changes: https://github.com/pentekl/redmine_gemavatar更新:我设置了一个包含更改的 github 存储库: https ://github.com/pentekl/redmine_gemavatar
You can use alias_method
instead of alias_method_chain
, but I'm searching for something like prepend
solution您可以使用
alias_method
而不是alias_method_chain
,但我正在寻找类似prepend
解决方案的东西
alias_method :avatar_without_gemavatar, :avatar
alias_method :avatar, :avatar_with_gemavatar
UPD: But it throws warnings: UPD:但它会发出警告:

UPD: As ste26054 mentioned in his answer and commented here require 'application_helper'
can be deleted to prevent warnings, since it already included in the core. UPD:正如ste26054 在他的回答中提到并在此处评论的那样,可以删除
require 'application_helper'
以防止警告,因为它已经包含在核心中。
