 \section{Ausgangssituation}
 Alle Informationen der Fakultät Elektrotechnik Feinwerktechnik Informationstechnik, kurz efi, werden über die globalen Verteiler des Hochschulinternen Postfaches versendet. Viele dieser Daten sind jedoch nur für eine geringe Schnittmenge der Empfänger relevant und lassen sich nur schwer priorisieren. Das ständig überlastete Postfach muss somit regelmä"sig gepflegt werden. Einen massiven Administrativen Aufwand bedeutet es, E-Mails zu filtern und nach persönlichem Ermessen zu verwalten.
+---genauer sagen woher ich mir sicher bin, dass das postfach überlastet ist
 Zudem leidet die Nachhaltigkeit der Informationen. Möchten die Empfänger ältere E-Mails abrufen, mussten diese meist schon entfernt werden um Platz für den neuen, eintreffenden E-Mail-Verkehr zu schaffen.
 Diese Situation führt dazu, dass Empfänger die Informationen meist nicht lesen und sofort entfernen. Die Ersteller haben keinerlei Möglichkeiten zu überprüfen ob und wie viele Studierende und Dozenten eingehende Nachrichten öffnen und lesen.
+---Forschungsfrage
 
 \section{Ziel der Arbeit}
 Ziel der Arbeit ist es, durch die Einbindung einer Social Media Plattform den Speicheraufwand des Hochschulpostfaches für Studierende der Efi-Fakultät zu reduzieren. Die Flut an E-Mails soll durch das Verwenden eines personalisierte Dashboard gedrosselt werden. Hierbei wird zunächst der Fokus auf die grundlegenden Funktionen der Website gelegt. Dazu gehört das Abonnieren, einpflegen von neuen und löschen von alten Nachrichten.
-Zudem sollen die Autoren benachrichtigt werden, in welchem Umfang die hochgeladenen Informationen bereits abonniert und gelesen wurden.

+Eine weitere hilfreiche Erweiterung ist pylint. Das Tool sucht nicht nur nach Fehlern im Code, sondern versucht diesen sauber und einheitlich zu gestalten. Hierbei wird auf den Code-Standard PEP-8 geprüft [Dix18]. Die folgende Liste zeigt eine Kurzfassung der wichtigsten Regeln:
+
+\begin{itemize}
+\item Einrückung, meist 4 Leerzeichen
+\item Maximale Zeichenanzahl pro Zeile
+\item Zwei Leerzeile zwischen Klassen und Funktionen
+\item Eine Leerzeile zwischen Methoden innerhalb einer Klasse
+\item Leerzeichen in Ausdrücke und Anweisungen vermeiden

 \chapter{Framework}
 \label{ch:framework}
 Um die Website-Erweiterung realisieren zu können, wird zunächst festgelegt welche Programmierschnittstellen verwendet werden. Im Web-Backend fällt die Wahl auf die objektorientierte Sprache Python, die ausschlie"slich Serverseitig anwendbar ist. Der Programmaufbau Pythons macht den Code leicht lesbar und der einfache Syntax ermöglicht einen strukturierte Implementierung der Website([Ndu17]). Die vielen abstrakten Datentypen, wie dynamische Arrays und Wörterbücher, sind gro"sflächig einsetzbar. 
+--- Warum genau python?
 Ein entscheidender Vorteil hierbei ist das dazugehörige Framework Django, auf das im folgenden Kapitel genauer eingegangen wird.
-
+---Ist pyton nur serverseitig?
 
 \section{Django}
-Django ist ein Web-Framework, das auf einer Model-View-Presenter (MVP) Architektur basiert. Ähnlich wie der Model-View-Controller sind die Interaktionen zwischen Model und View die Auswahl und Ausführung von Befehlen und das Auslösen von Ereignissen (vgl. Abbildung 2.1). Da die View aber hier bereits den Gro"steil des Controllers übernimmt, ist der MVP eine Überarbeitung. Der Teil, der Elemente des Modells auswählt, Operationen durchführt und alle Ereignisse kapselt, ergibt die Presenter-Klasse([She09]). Durch die direkte Bindung von Daten und View, geregelt durch den Presenter, wird die Codemenge der Applikation stark reduziert.

Das Interface WSGI am Web-Server verbindet diesen mit dem Web-Framework, indem es den Request zum passenden Objekt weiterleitet. Hier wird der Applikation eine Callback-Funktion zur Verfügung gestellt (vgl. [Kin17]). Au"serdem werden folgende Schritte durchgeführt:
 \begin{itemize}
 \item Die Middleware-Klassen aus der settings.py werden geladen
 \item Die Methoden der Listen Request, View, Response und Excpetion werden geladen
 \end{itemize}
 
 Der WSGI-Handler fungiert also als Pförtner und Manager zwischen dem Web-Server und dem Django-Projekt.
-Um die URL, wie weiter oben erwähnt, aufzulösen, benötigt WSGI einen urlresolver. Durch die explizite Zuweisung der vorhandenen Seiten, kann dieser über die regulären Ausdrücke der url.py-Datei iterieren. Gibt es eine Übereinstimmung, wird die damit verknüpfte Funktion in der View (view.py) aufgerufen. Hier ist die gesamte Logik der Website lokalisiert. Wie bereits erwähnt, ist es möglich unter Anderem auf die Datenbank der Applikation zuzugreifen und Eingaben des Users über eine Form zu verarbeiten. Nachdem werden die Informationen der View an das Template weitergereicht. Es handelt sich dabei um eine einfache HTML-Seite in der der strukturelle Aufbau im Frontend festgelegt wird. Die Informationen der View können hier zwischen doppelt-geschweiften Klammern eingebunden und, wenn nötig, mit einfachen Python-Befehlen angepasst werden. Nun kann das Template, die vom WSGI-Framework zur Verfügung gestellte Callback-Funktion befüllen und einen Response an den Web-Server schicken. Die fertige Seite ist beim Klienten im Browserfenster zum rendern bereit (vgl. Abbildung 2.2.).

-\subsection {Besonderheiten}
+\subsection {Besonderheiten Django's}
 Das Django-Framework bringt einige Besonderheiten mit sich, die beim implementiern des Prototypen von Bedeutung sind. Diese werden im Folgenden beschrieben.
 
 Die Administratoroberfläche ist eines der hilfreichsten Werkzeugen des gesamten Frameworks. Es stellt die Metadaten der Modelle aus dem Code visuell dar. Verifizierte Benutzer können die Daten nicht nur schnell erfassen, sondern diese auch editieren und verwalten. Das Recht, das Admin-Backend uneingeschränkt zu benutzen, ist dem sogenannten superuser vorenthalten. Dieser kann beim erstmaligen zuweisen nur über die Kommandozeile eingerichtet werden. Ist bereits ein superuser vorhanden, kann dieser im Admin-Backend weiteren Benutzern den gleichen Handlungsfreiraum einräumen. Zudem gibt es noch weitere Stufen der Zugangsberechtigungen, Staff- und Active-Status, die für eine breitere Gruppe von Benutzern geeignet ist.
-Um  die gestaffelten Zugangsberechtigungen auch auf der Website umsetzen zu können, stellt Django verschiedene Decorator zur Verfügung. Soll eine bestimmte Seite nur von eingeloggten Benutzern besucht werden dürfen, so importiert man die Decorator des, von Django zur Verfügung gestellten, Authentifizierungssystems mit 
+Um  die gestaffelten Zugangsberechtigungen auch auf der Website umsetzen zu können, stellt Django verschiedene Decorator zur Verfügung. Soll eine bestimmte Seite nur von eingeloggten Benutzern besucht werden, so importiert man die Decorator des, von Django zur Verfügung gestellten, Authentifizierungssystems mit 
 \\
 \noindent\hspace*{10mm}%
 from django.contrib.auth.decorators import login\_required
 \\
-Direkt über den Beginn der Funktion in view.py, oder auch single-view-function, wird zudem folgende Zeile ergänzt:
+Vor der Definition der Funktion wird dann folgende Zeile ergänzt:
 \\
 \noindent\hspace*{10mm}%
 \makeatletter @login\_required
 \\
-Natürlich lassen sich die Decoratoren auch für andere Zwecke vor Funktionen platzieren. Begrenzte Zugänge zu den Views können durch die Art der Anfrage realisiert werden. Der Benutzer muss also zum Beispiel durch GET auf eine Seite zugreifen wollen um Einsicht zu erhalten.
-
-Benutzerdefinierte Decorator sind im Django-Framework möglich, darauf wird hier aber nicht weiter eingegangen.
-
+Natürlich lassen sich Decorator auch für andere Zwecke vor Funktionen platzieren. Unter Anderem werden so die Views vor möglichen Angriffen, wie Cross-Site-Scripting, geschützt. 
 
+Durch den einfachen Aufbau ist es au"serdem möglich diese selbst zu implementieren. Ein einfaches Beispiel wäre das prüfen des, an die Funktion übergebenen, Parameter. Sollen nur positive Zahlen verarbeitet werden, so kann der Decorator alle anderen Eingaben abfangen. 
 
 
+\subsection{Virtuelle Umgebung}
 
-\section{Erweiterungen}
-
-Die Programmiersprache Python bringt viele hilfreiche Erweiterungen mit sich. Die im folgenden aufgeführten sind hauptsächlich für die Paketverwaltung der Applikation zuständig. 
-
-Wird ein neues Projekt gestartet, ist es üblich, verschiedensten Programme und Module dafür zu verwenden. Die Versionen dieser spielen hierbei eine entscheidende Rolle, um Konflikte zu vermeiden [Fou18]. Um diesem Problem vorzubeugen, wird eine virtuelle Umgebung implementiert. Diese besitzt einen eigenen Projektpfad, beinhaltet alle nötigen Pakete und Bibliotheken, und lässt sich nach dem Einrichten im Terminal benutzten. Die folgende Abbildung (2.3) zeigt das Erstellen eines neunen Ordners, das Erstellen der virtuellen Umgebung und den Aktivierungsbefehl. Ist der Name des Environment in Klammern am Anfang der Zeile, bedeutet das, diese ist jetzt aktiv.

 \begin{figure}[!h]

 Die Umgebung ist jetzt bereit befüllt zu werden. Um die Pakete und Module kollisionsfrei zu installieren ist es empfehlenswert einen Package-Manager zu verwenden. Mit pip können diese installiert, geupdated und gelöscht werden. Au"serdem kann der Manager Abhängigkeiten, wenn nötig, überschreiben und optimieren. Falls ein, sich von der neuesten Version unterscheidendes, Programm installiert werden soll, so ist dies ebenso möglich.

+\subsection{Lightweight Directory Access Protocol}
 
 Das ldap, Lightweight Directory Access Protocol, muss als Erweiterung in die hier bearbeitende Bachelor-Arbeit eingebunden werden. Dies ist ein Internetprotokoll, welches die Kommunikation mit dem Hochschulinternen Active Directory verwaltet. Es wird eingesetzt um Benutzer so schnell und effizient wie möglich durch eine bereits existierende Datenbank abzufragen und zu authentifizieren. Der Aufbau ist mit einem Baum zu vergleichen (vgl. Abbildung 2.4.). Die Wurzel besteht aus sehr allgemeinen Informationen, umso näher man den Blättern kommt, umso spezifischer werden diese. Ein Objekt in der Struktur wird durch einen einmaligen Namen identifiziert, der aus den gesamten hinterlegten Informationen besteht. Der Name für den in der Abbildung 2.4 dargestellten Baum wäre \glqq cn=John Doe, ou=People, dc=sun.com\grqq.

+\section {Erweiterungen}
+Django bringt viele hilfreiche Erweiterungen mit sich, die mit einem Packagemanager einfach in die virtuelle Umgebung geladen werden können. Um das passende Add-on für ein Projekt zu finden, bietet die Plattform djangopackages.org alle Erweiterungen in übersichtlichen Tabellen mit Eigenschaften und Bewertung an.
+
 \subsection {Taggable-Manager}
-Django-taggit ist eine Erweiterung von Alex Gaynor, einem Entwickler aus Washingtion DC. Das Add-on ermöglicht das Verwenden von Tags die automatisch mit einem eindeutigen Slug versehen werden. Der darin enthaltene Taggable Manager verwendet Django's Contenttype Framework, welches per Default verwendet wird, um die Modelle der Applikation zu verfolgen und diese durch generische Beziehungen zu verknüpfen. Die Felder app\_label und model machen die Modelle eindeutig zuweisbar. Instanzen des Contenttypes präsentieren und speichern die Informationen und Erstellen automatisch neue Instanzen, wenn Modelle hinzugefügt werden. Zudem stehen Methoden zur Verfügung, die das Abrufen und Arbeiten mit Instanzen der einzelnen Modelle erleichtern.
+Django-taggit ist eine Erweiterung, die das Verwenden von Tags vereinfacht.

Die Felder app\_label und model machen die Modelle eindeutig zuweisbar. Instanzen des Contenttypes präsentieren und speichern die Informationen und Erstellen automatisch neue Instanzen, wenn Modelle hinzugefügt werden. Zudem stehen Methoden zur Verfügung, die das Abrufen und Arbeiten mit Instanzen der einzelnen Modelle erleichtern.
 
 Der Taggable-Manager ist jedoch nicht an das Contenttype-Framework gebunden ([Her16]). Durch die Verwendung eines echten Fremdschlüssels, kann zum Beispiel die Performance und Referenzgarantie verwirklicht werden. Dazu ist lediglich die Erstellung einer eigenen lookup-Tabelle notwendig, die die Entitäten zweier Tabellen direkt verlinkt, anstatt diese generische zu verbinden. Weiterführend können Modelle in einem benutzerdefinierten Modell vereint werden, sodass er Zugriff auf diese einheitlich geschieht. Außerdem ist es möglich Primary-Keys zu verwenden, die nicht aus ganzen Zahlen bestehen, sondern aus Buchstaben und Wörtern.
 
 \$ pip install django-taggit 
 \\
 Im model.py wird das Feld tag neu erstellt und als Taggable Manager definiert.
-Au"serdem muss taggit in der settings.py unter INSTALLED\_APPS ergänzt werden. Um dem Programm zu sagen, dass nun eine neue Liste der Datenbank hinzugefügt werden muss, werden folgende Befehle in die Kommandozeile eingefügt:
+Au"serdem muss taggit in der settings.py unter INSTALLED\_APPS ergänzt werden. Um dem Programm mitzuteilen, dass nun eine neue Liste der Datenbank hinzugefügt werden muss, werden folgende Befehle in die Kommandozeile eingefügt:
 \\
 \noindent\hspace*{10mm}%
 \$ python3 manage.py makemigrations \\
 \\
 Im Admin-Backend kann nun geprüft werden, ob das neue Feld in die Datenbank integriert wurde. Neue Tags können in das Textfeld eingetragen werden. Der Parser verarbeitet jedes Wort, dass durch ein Komma oder ein Leerzeichen getrennt ist als ein Tag. Soll dieses jedoch aus mehreren Wörtern bestehen so müssen diese mit Anführungszeichen umfasst werden. Standardmäßig unterscheidet der Taggable Manager zwischen Groß- und Kleinschreibung, Tags sind also case sensitive. Ändern kann man das, indem der Boolean TAGGIT\_CASE\_INSENSITIVE in der settings.py auf True gestellt wird.
 
+\subsection {Hilfsbibliotheken}
+Weitere Add-ons werden geladen um kleinere Funktionen der Website einfach umsetzen zu können. Zu diesen gehört django-taggit-templatetags, welches durch die Einbindung im HTML-File die Tags der Applikation als Liste ausgibt. Au"serdem lassen sich die eingepflegten Tags als Cloud visualisieren. Kommen bestimmte Tags öfters vor als andere, so werden sie entsprechend grö"sser dargestellt.
+
+Django-hitcount dient zum zählen der Besucher einer Seite ([Tim15]). Dies lässt sich auf drei verschiedene Arten in die Applikation einbinden. Der schnellste Weg ist die Darstellung der Besuche mit Hilfe eines Template Tags im HTML-File. Möchte man die Anzeige aber individueller gestalten so kann durch das integrieren der HitCountDetailView in views.py die Variable hitcount verwenden und im Frontend ausgeben. Eine weiter Möglichkeit ist das Erweitern oder neu Erstellen eines Models im Django Backend. Von dort kann auf das neue Feld im Django-Admin-Backend zugegriffen werden, ebenso wie in der View und im Template. Die im Add-on integrierten Einstellungen, die in der settings.py ergänzt werden müssen, ermöglichen unter Anderem das begrenzen der Lebensdauer des Zählers, bevor dieser zurück gesetzt wird.
+
+Um das Versenden und Verwalten von E-Mails in Django zu realisieren eignet sich django-post-office ([Ong18]). Nach der Installation kann im Admin-Backend ein E-Mail-Templates angelegt werden, Anhänge verwaltet und das Senden dieser im Log überprüft werden. Die Benachrichtigungen können asynchron versendet werden mit einem integrierten Planungsmanager. Der Inhalt kann Text oder HTML-basiert sein und in mehreren Sprachen hinterlegt werden.

 \section{Bootstrap}
-Eine umfangreiche Website einheitlich zu gestalten ist oft sehr komplex und zeitaufwendig. Die Entwickler von Twitter haben deshalb, zunächst Firmenintern, an einem neuen Verwaltungswerkzeug gearbeitet, das mehrere Bibliotheken zusammenführen sollte. Sie merkten, das die neue Bibliothek, die daraus entstand, nicht nur auf Ihre eigene Website anwendbar, sondern so flexible ist, dass jede Art von Website davon profitieren könnte. 2011 entschieden Sie sich Bootstrap für die Öffentlichkeit frei zugänglich zu machen. Die Open-Source-Bibliothek, die auf GitHub abrufbar ist, wird seitdem von vielen interessierten Programmierern weiterentwickelt und ist somit stark gewachsen. Version 2.0 verfügt au"serdem über die Fähigkeit Websites responsive auf verschiedenste mobile Endgeräte anzupassen.

-Das Bootstrap-Paket beinhaltet vorgefertigte Cascading Stylesheets, kurz CSS, die Farben, Schriftarten und viele weitere Stildefinitionen. Zudem befinden sich auch Erweiterungen des JavaScript-Frameworks jQuery in der Bibliothek, die weiterführende Funktionen beinhalten wie zum Beispiel Filter oder Dropdown-Menüs. Das Paket kann einfach eingebunden werden im head-tag einer HTML-Datei (vgl. Abbildung 2.3). Das bedeutet, dass Medie-Queries oder ähnliche Methoden nicht mehr nötig sind, nicht nur um eine Website mobilfähig zu machen, sondern auch kompatibel für die verschiedensten Browser.

-Durch das Einbinden von Bootstrap in einer HTML-Datei werden einige Styles bereits automatisch auf die darin vorkommenden Tags, wie Links und Überschriften, angewandt. Dies ist jedoch nur ein sehr kleiner Teil den die Bibliothek zur Verfügung stellt. Möchte man Bootstrap umfangreich nutzen so lassen sich die Stildefinitionen mit Klassen oder ID's in diverse HTML-Tags eintragen (vlg. Abbildung 2.4.).

+Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for UNIX. It's a pre-fork
+worker model ported from Ruby's Unicorn_ project. The Gunicorn server is broadly
+compatible with various web frameworks, simply implemented, light on server
+resource usage, and fairly speedy.

 pyparsing module - Classes and methods to define and execute parsing grammars
+=============================================================================
 
 The pyparsing module is an alternative approach to creating and executing simple grammars,
 vs. the traditional lex/yacc approach, or the use of regular expressions.  With pyparsing, you
  - extra or missing whitespace (the above program will also handle "Hello,World!", "Hello  ,  World  !", etc.)
  - quoted strings
  - embedded comments
+
+
+Getting Started -
+-----------------
+Visit the classes L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing
+classes inherit from. Use the docstrings for examples of how to:
+ - construct literal match expressions from L{Literal} and L{CaselessLiteral} classes
+ - construct character word-group expressions using the L{Word} class
+ - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes
+ - use L{'+'<And>}, L{'|'<MatchFirst>}, L{'^'<Or>}, and L{'&'<Each>} operators to combine simple expressions into more complex ones
+ - associate names with your parsed results using L{ParserElement.setResultsName}
+ - find some helpful expression short-cuts like L{delimitedList} and L{oneOf}
+ - find more useful common expressions in the L{pyparsing_common} namespace class
