djangoAMFを使ってユーザー登録機能のベースを作る

今後も使いそうなので作っておく。

環境はflex2とs2flex2とdjango開発版。
簡単な入力チェック機能付き。
flex側はTitleWindowなので別途それを表示するための機能を追加する必要あり。

flex側表示用mxml(UserEntryWindow.mxml)

<?xml version="1.0" encoding="utf-8" ?>
<mx:TitleWindow
    xmlns:mx="http://www.adobe.com/2006/mxml"
    xmlns:s2="http://www.seasar.org/s2flex2/mxml"
    title="ユーザ登録"
    creationComplete="init();"
    >
<s2:RemoteService
        id="accountService"
        gatewayUrl="http://localhost:8000/gateway/"
        destination="accountService"
        showBusyCursor="true"
        useAMF0="false"
        result="event.token.resultHandler(event)"
        fault="event.token.faultHandler(event)" />
<mx:Script source="UserEntryWindow_script.as" />
<mx:StringValidator id="vfirst_name" source="{ifirst_name}" property="text" required="true" />
<mx:EmailValidator id="vemail" source="{iemail}" property="text" required="true" />
<mx:RegExpValidator id="vusername" source="{iusername}" property="text" expression="[a-zA-Z0-9_\-]" />
<mx:RegExpValidator id="vpassword" source="{ipassword}" property="text" expression="[a-zA-Z0-9_\-]" />
<mx:Form percentWidth="100">
<mx:FormItem label="ニックネーム" percentWidth="100">
<mx:TextInput id="ifirst_name" percentWidth="100" />
</mx:FormItem>
<mx:FormItem label="メールアドレス" percentWidth="100">
<mx:TextInput id="iemail" percentWidth="100" />
</mx:FormItem>
<mx:FormItem label="ログイン名" percentWidth="100">
<mx:TextInput id="iusername" percentWidth="100" />
</mx:FormItem>
<mx:FormItem label="パスワード" percentWidth="100">
<mx:TextInput id="ipassword" percentWidth="100" displayAsPassword="true" />
</mx:FormItem>
</mx:Form>
<mx:ControlBar percentWidth="100" id="ctrlBar">
<mx:Spacer width="100%" />
<mx:Button label="登録" id="userEntryBtn" click="userEntry(event);" />
<mx:Button label="キャンセル" id="cancelBtn" click="cancelEntry(event);" />
</mx:ControlBar>
</mx:TitleWindow>

flex側スクリプト部分(UserEntryWindow_script.as)

private function handleUserCreateFault(event:FaultEvent):void {

django側(url.py)

from django.conf.urls.defaults import *
from django.conf import settings
import amf.django
urlpatterns = patterns('',
(r'^static/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}),
(r'^gateway/accountService/(.*)', 'amf.django.views', {'views': 'samplepj.main.account_views'}),
)

django側(account_views.py)

# vim:set fileencoding=utf-8:
from django.db import IntegrityError
from samplepj.main.models import *
CODE_SUCCESS = 1
CODE_WARN = 2
CODE_ERROR = -1
def create_user(request, user_form):
user = User()
user.first_name = user_form["first_name"]
user.email = user_form["email"]
user.username = user_form["username"]
user.set_password(user_form["password"])
try:
user.save()
result = {'code': CODE_SUCCESS}
except IntegrityError:
result = {'code': CODE_ERROR, 'message': "ログイン名が重複しています"}
return result
