+# ckan feedback init
+
+## 概要
+
+指定した機能に関係するPostgreSQLのテーブルを初期化する。
+
+## 実行
+
+```
+ckan feedback init [options]
+```
+
+### オプション
+
+#### -m, --modules < utilization/ resource/ download >
+
+**任意項目**
+
+一部の機能を利用する場合に以下の3つから指定して実行する。(複数選択可)  
+このオプションの指定がない場合は全てのテーブルに対して初期化処理を行う。
+* utilization
+* resource
+* download
+
+##### 実行例
+
+```
+# ckanext-feedback plugins に関わる全てのテーブルに対して初期化を行う
+ckan --config=/etc/ckan/production.ini feedback init
+
+# utilization(利活用方法)機能に関わるテーブルに対して初期化を行う
+ckan --config=/etc/ckan/production.ini feedback init -m utilization
+
+# resource(データリソース)機能に関わるテーブルに対して初期化を行う
+ckan --config=/etc/ckan/production.ini feedback init -m resource
+
+# download(ダウンロード)機能に関わるテーブルに対して初期化を行う
+ckan --config=/etc/ckan/production.ini feedback init -m download
+
+# resource(データリソース)機能とdownload(ダウンロード)機能に関わるテーブルに対して初期化を行う
+ckan --config=/etc/ckan/production.ini feedback init -m resource -m download
+```
+
+※ ckanコマンドを実行する際は```--config=/etc/ckan/production.ini```と記述して、configファイルを指定する必要がある
+
+#### -h, --host <host_name>
+
+**任意項目**
+
+PostgreSQLコンテナのホスト名を指定する。

+
+#### -d, --dbname <db_name>
+
+**任意項目**
+
+PostgreSQLのデータベース名を指定する。  
+指定しない場合、以下の順で参照された値を使用する。
+1. 環境変数 ```POSTGRES_DB```
+2. CKANのデフォルト値 ```ckan```
+
+#### -u, --user <user_name>
+
+**任意項目**
+
+PostgreSQLに接続するためのユーザ名を指定する。

+1. 環境変数 ```POSTGRES_PASSWORD```
+2. CKANのデフォルト値 ```ckan```
+
+##### 実行例
+
+```
+# ホスト名として"postgresdb"を指定する
+ckan --config=/etc/ckan/production.ini feedback init -h postgresdb
+
+# ポート番号として"5000"を指定する
+ckan --config=/etc/ckan/production.ini feedback init -p 5000
+
+# データベース名として"ckandb"を指定する
+ckan --config=/etc/ckan/production.ini feedback init -d ckandb
+
+# ユーザ名として"root"を指定する
+ckan --config=/etc/ckan/production.ini feedback init -u root
+
+# パスワードとして"root"を指定する
+ckan --config=/etc/ckan/production.ini feedback init -P root
