attach

attachプラグイン

 もともとのHikiでは、attach(ファイル添付)プラグインを使う時には、misc/plugin/attach/attach.cgiをHikiのルートにコピーして使っていました。

 Rackで動かす場合にはこの作業は必要ありません。

 CGIでRackブランチを動かす場合も、大抵は必要ありません。

 が、サーバーの設定のせいで/attachへのリクエストをhiki.cgiに投げられない場合、やはりmisc/plugin/attach/attach.cgiをHikiルートにコピーする必要があります。

 それでもうまく行かない場合は、hikiconf.rbに

@options = {}
@options['attach.cgi_name'] = 'attch.cgi'

と書き込んで、Hikiルートにアップしてください。

ファイル添付機能の変更

このHikidashiブランチは、Commit 16d6f549e1d47daf794a(2010年10月24日)から、ファイル添付機能の実装を変更しました。

  • CGIで動かす場合でもattach.cgiは不要になりました。
  • 権限の管理はHTTP Auth(.htaccessと.htpasswd)ではなくHikiの権限管理を使うようになりました。
    • 特定のユーザーにのみファイル添付 / 削除を許可したい場合にはedit_userプラグインを使ってください。
  • ファイル添付のPOSTリクエストを直接/attachへ送っていた場合には/?c=attachに送るよう、変更してください。

プラグイン実例

  • Anchor to the attached file is {{attach_anchor(file name [, page name])}}.
  • Indication of the attached file is {{attach_view(file name [, page name])}}.
  • List of the attached pages and files is {{attach_map}}.
