[plugin][redmine]redmine_issue_extensionsの導入・テスト

redmine_issue_extensionsの導入と稼働させるまでの対応について、纏めてみた。

１．コードの導入
（参考）
planio-gmbh/redmine_issue_extensions
　https://github.com/planio-gmbh/redmine_issue_extensions

[root@0hostname plugins]# git clone https://github.com/planio-gmbh/redmine_issue_extensions.git
Cloning into 'redmine_issue_extensions'...

remote: Total 864 (delta 0), reused 0 (delta 0), pack-reused 864
Receiving objects: 100% (864/864), 275.59 KiB | 164.00 KiB/s, done.
Resolving deltas: 100% (132/132), done.

２．pluginの導入

[root@hostname htdocs]# rake --trace redmine:plugins:migrate NAME=redmine_issue_extensions RAILS_ENV=production
An error occurred while loading the routes definition of redmine_issue_extensions plugin (/opt/redmine/apps/redmine/htdocs/plugins/redmine_issue_extensions/config/routes.rb): You should not use the `match` method in your router without specifying an HTTP method.
If you want to expose your action to both GET and POST, add `via: [:get, :post]` option.
If you want to expose your action to GET, use `get` in the router:
Instead of: match "controller#action"
Do: get "controller#action".

３．エラーの対応：RAILS4でサポートされない表記方法を修正する
（１）match を get に変更
［修正対象候補リスト］:ここら辺をごにょごにょする。

☆/opt/redmine/apps/redmine/htdocs/plugins/redmine_issue_extensions/config/routes.rb
match 'issue_extensions/:action', :controller => 'issue_extensions', :via => [:get, :post]
match 'issue_extensions_settings/:action', :controller => 'issue_extensions_settings'
match 'issue_relations/:action', :controller => 'issue_relations', :via => [:get, :post]

（２）findメソッドの変更
［修正対象候補リスト］:ここら辺をごにょごにょする。

☆/opt/redmine/apps/redmine/htdocs/plugins/redmine_issue_extensions/app/models/issue_extensions_status_flow.rb
　status_flow = IssueExtensionsStatusFlow.find :first, :conditions => ['project_id = ?', project_id]
☆/opt/redmine/apps/redmine/htdocs/plugins/redmine_issue_extensions/app/views/issue_extensions_settings/_show.html.erb
　@statuses = IssueStatus.find(:all, :order => 'position') %>
☆/opt/redmine/apps/redmine/htdocs/plugins/redmine_issue_extensions/lib/issue_extensions_issue_hooks.rb
　issue_status = IssueExtensionsStatusFlow.find :first, :conditions => ['project_id = ?', issue[:project_id].to_i]
　issue_status_closed = IssueStatus.find :all, :conditions => ["is_closed = (?)", true]
　if Watcher.find :first, :conditions =>["watchable_type = (?) and watchable_id = (?) and user_id = (?)", journal[:journalized_type], issue[:id].to_i, journal[:user_id].to_i] == nil
　from_issue = Issue.find :first, :conditions =>["id = (?)", params[:relation_issue_id].to_i]
☆/opt/redmine/apps/redmine/htdocs/plugins/redmine_issue_extensions/app/views/issues/_issue_extensions_form.erb
　searched_issues = Issue.find(:all, :conditions => ["project_id = ? AND subject LIKE (?)", @issue.project_id, '%' + cb_subject + '%']) unless cb_subject == "" %>

（３）link_to_remoteの変更
［修正対象候補リスト］:ここら辺をごにょごにょする。

☆/opt/redmine/apps/redmine/htdocs/plugins/redmine_issue_extensions/app/views/issues/_issue_extensions_form.erb
link_to_remote image_tag('edit.png') + l(:label_add_relation), {
:url => {:controller => 'issue_relations', :action => 'create', :issue_id => @issue, :id => @issue.id, :relation => {:relation_type => 'relates', :issue_to_id => earched_issue.id}},
:method => :post
}

なんとか、トップの画像のような表示と、完了で進捗率100%と設定、コメント入れるとウォッチャに登録してくれる機能が実現された。
