利用者属性の登録
次に、OpenIDで認証した人がニックネームと時差を登録できるようにする。
モデル
- model/__init__.py

フォーム準備
- これはPylonsでは定石
lib/helpers.py
from routes import url_for from formbuild.helpers import field from formbuild import start_with_layout as form_start, end_with_layout as form_end from webhelpers.html.tags import *
- フォーム作成に必要なモジュールを取り込んでおく。

- TimeDiffForm...フォーム内容チェックのためのデコレータ。
- nicknameとtime_diffの型チェックおよび必須チェック
- ClockController
- __init__で、SimpleDBとの接続を確立→sqlalchemyみたいにSession()に取り込むのが理想。
- now()ではSimpleDBから属性を取り込み、表示。データがない場合はOpenIDとゼロがそれぞれ入る。
- customize()は登録フォーム表示
- save()はフォームのサブミット先。
templates/derived/clock/now.html
<%inherit file="/base/index.html"/> ${c.content} <br/> You can <a href="${h.url_for(action = 'customize')}">customize</a>. <br/> <a href="${h.url_for(action = 'signout')}">Signout</a>
- 時差計算をした時刻を表示するように改造。
- 属性変更画面へのリンクを追加。
templates/derived/clock/customize.html
<%inherit file="/base/index.html"/> <%namespace file = "fields.html" name = "fields" import = "*"/> ${h.form_start(h.url_for(action = 'save'), method = 'post')} ${fields.body()} ${h.field(field = h.submit(value = "Save", name = "submit"))} ${h.form_end()}
- 属性登録画面。フォームの項目は次のファイル。
templates/derived/clock/fields.html
${h.field(
"Nickame",
h.text(name = 'nickname'),
required = False,
)}
${h.field(
"Time Diff",
h.text(name = 'time_diff'),
required = False,
)}
