私はプログラミングに不慣れで、GAEデータストアの概念を理解しようとしています。契約書を簡単に作成できるアプリを作成しようとしています(http://contractpy.appspot.com)。現時点では、URLからコントラクトテンプレートをレンダリングするために必要なすべての値を次のように渡します。
self.redirect('/your_contract?person=%s&nacionality=%s&profession=%s&maritalStatus=%s&SSN=%s&driverLicense=%s&email=%s&witness=%s&owner=%s&contractType=%s&address=%s' % (person_name, user_nacionality, user_profession, user_maritalStatus, user_SSN, user_driverLicense, user_email,
#witness, owner, contractType, address))
ただし、そうすることで、1人に制限されたままになります(将来的には、同じ契約で複数の人のデータをレンダリングする必要があります)。
その代わりに、GAEデータストアクエリを使用して、テンプレート「your_contract.html」の変数値を入力したいと思います。
簡単な質問だとは思いますが、GAEデータストアは私には完全にわかりにくく(「データストアの禅」はまだ理解していませんが、SQLについては少し理解しています)、OOProgrammingを今学んでいます。私はこの記事を読み、このサンプル(Googleのguess_booKサンプル)をフォローしようとしましたが、この頭脳には十分ではありませんでした。では、このクエリを実行して、1つのテンプレートに複数の人物のデータをレンダリングするための最良の方法は何でしょうか。(クラスパーソンは以下のコードにあります)
私はこのように考えていました:URLを介して各人の1つのデータ(例:運転免許証番号)のリストを渡します:
self.redirect('/your_contract?driverLicense=%s' % (driverLicenseList))
また、ハンドラー「your_contract」で、「diverLicenseList」の値を使用して(リストを操作した後)、次のようにGAEデータストアにクエリを実行します。
x = self.request.get('SSN')
contractingParty = db.GqlQuery("SELECT FROM Person WHERE SSN IS x")
これは正しい道ですか?助けてくれてありがとう!
私の元のコード(GAEクエリを実行する前)はここにあります:
