2.2.2 Mert YILDIZ Tarafından Yapılan Kısımlar

Psycopg2 Metodunun Açıklaması

con(): PostgreSQL veri tabanına baglantı saglanmasını halleder.

cursor(): PostgreSQL komutlarının python kodunda çalıstırılmasını saglar.

execute(): Veri tabanı isleminin çalıstırılmasını saglar.(Sorgu yada komutların)

commit(): bekleyen degisiklik yada islemleri veri tabanına isler.

fetchall(): Sorgu sonucunu alır ve satırlar halinde döner.

Üniversiteler

Üniversiteleri temsil etmek için sistemde iki adet tablo gerçeklendi. Bunlardan ilki olan “universities” tablosu “id”ve “title” niteliklerinden olusan basit bir tablodur. “id” niteligi birincil anahtar olup “Serial” olarak tanımlanmıstır.Diger nitelik olan “title” da ise üniversitelerin isimleri yer almaktadır. Bu tablo site açıldıgında asagıdaki kod ileolusturulup, ilk degerleri atanmaktadır.

Üniversiteler hakkında daha detaylı bilgilerin bulundugu diger bir tablo ise “universities_info” tablosudur. Butabloda “uni_id”,”local”,”population” ve “type” olmak üzere dört nitelik vardır. Bunlardan uni_id universities tab-losundaki id ile iliskili dıs anahtar, local ise locations tablosundaki loc_id ile iliskili bir dıs anahtardır.

Üniversite Güncelle

Üniversite güncellemek için önce arayüzde istenen üniversitenin yanındaki “Güncelle” linkine tıklanması ardındanaçılan yeni sayfada yeni bilgilerin girilerek “Güncelle” butonuna basılması gerekmektedir. Iste Html kodunda, is-tenen üniversitenin yanındaki linke tıklandıgında bu üniversitenin id degerinin gönderilmesiyle “/universiteler/id”uzantılı yeni bir sayfa açılır. Daha sonra bu id degerine sahip üniversite için yeni girilen bilgiler kullanılarakgüncelleme islemi yapılır. Html kısmındaki yeni sayfaya yönlendiren ve id degerini gönderen kod su sekildedir.

Buradan gelen id ile yeni açılan sayfaya ait server.py daki kod ise asagıdaki gibidir. Bu koda göre öncelikle sayfa-nın metodu “GET” ise güncellenecek olan üniversitenin bilgileri yeni açılan sayfadaki metin kutularına doldurulur.Eger “POST” ise yani “Güncelle” butonuna basılırsa, seçili üniversitenin id degerine göre seçim yapılarak yeniveriler ile güncelleme islemi yapılır ve ardından üniversiteler sayfasına geri dönülür.

Üniversite Seçme

Arayüzde girilen belirli kriterlere göre üniversite bilgilerini seçme islemi yapmak için kullanılan kısımdır. Seçmeislemi için önce bir sehir girilir, ardından bu sehirdeki özel, devlet yada her ikisi birden seçilerek istenen türbelirtilir. Yapılan bu seçimlere göre tablolardan istenen kriterlere uyan üniversiteler çekilerek yeni bir sayfadalistelenir. Bu islemler için server.py’da yazılan kod su sekildedir:

Görüldügü üzere öncelikle “Seç” butonuna basılması beklenir, bu butona basılırsa, “Özel” ve “Devlet” degerlerinitasıyan kontrol kutularının degerleri ve girilen sehir bilgisi alınır. Önce kontrol kutularının ikisininde mi yoksabirinin mi seçildigine bakılır. Ikiside seçildiyse girilen sehre göre seçme islemi yapılır. Eger yanlızca “Özel” veya“Devlet” seçildiyse o zaman bu kriterde seçimde göz önüne alınır.

Eger yanlıs deger girilirse hata sayfasına yönlendirilir.(404.html)

Sirketler

Sirketleri temsil etmek için sistemde “companies” tablosu gerçeklendi. Tablo “id”, “title”, “local2” ve “popula-tion” olmak üzere dört nitelikten olusmaktadır. Bunlarda sırasıyla sirketin sıra numarası(birincil anahtar olarakkullanıldı.), sirketin ismi, yer bilgisi(“locations” tablosuna dısa anahtar olarak) ve çalısan sayısı bilgileri tutul-maktadır. Bu tablo site açıldıgında asagıdaki kod ile olusturulup, ilk degerleri atanmaktadır.

Sirket Güncelle

Sirket güncellemek için önce arayüzde istenen sirketin yanındaki “Güncelle” linkine tıklanması ardından açılanyeni sayfada yeni bilgilerin girilerek “Güncelle” butonuna basılması gerekmektedir. Iste Html kodunda, istenensirketin yanındaki linke tıklandıgında bu sirketin id degerinin gönderilmesiyle “/sirketler/id” uzantılı yeni bir sayfaaçılır. Daha sonra bu id degerine sahip sirket için yeni girilen bilgiler kullanılarak güncelleme islemi yapılır. Htmlkısmındaki yeni sayfaya yönlendiren ve id degerini gönderen kod su sekildedir.

Buradan gelen id ile yeni açılan sayfaya ait server.py daki kod ise asagıdaki gibidir. Bu koda göre önceliklesayfanın metodu “GET” ise güncellenecek olan sirketin bilgileri yeni açılan sayfadaki metin kutularına doldurulur.Eger “POST” ise yani “Güncelle” butonuna basılırsa, seçili sirketin id degerine göre seçim yapılarak yeni verilerile güncelleme islemi yapılır ve ardından sirketler sayfasına geri dönülür.

Görüldügü üzere öncelikle “Seç” butonuna basılması beklenir, iki farklı “Seç” butonu vardır. Ilki olan “compa-nies_to_select” butonuna basılırsa seçme için sehir kriterine bakılacagı anlamına gelir. Bu nedenle girilen sehirdegeri kullanılarak buna uygun olan sirketler tablodan çekilerek, yeni bir sayfada listelenir. Eger ikinci buton olan“companies_to_select2” kullanılırsa bu isme göre seçme yapılacagını gösterir ve girilen isim degeri kullanılarakislem yapılır. Bulunan sonuçlar yeni bir ekranda listelenir.

Eger yanlıs deger girilirse hata sayfasına yönlendirilir.(404.html)

Hata Sayfası

Eger kullanıcı seçme gibi islemlerde yanlıs yada sistemde olmayan veriler girerse “internal server error” hatasıyerine bu hazırlanan sayfanın görünmesi saglandı. Bunun için bu kosula uygun durumlar belirlenerek server.pydosyasında gerekli yerlerde yönlendirmeler yapıldı. Örnek kullanım yerleri asagıda gösterilmistir.

Yerler

Yerler temsil etmek için sistemde “locations” tablosu gerçeklendi. Tablo “id”, “city” ve “country” olmak üzere üçnitelikten olusmaktadır. Bunlarda sırasıyla yerin numarası(birincil anahtar olarak kullanıldı.), sehir ve ülke bilgileritutulmaktadır. Bu tablo site açıldıgında asagıdaki kod ile olusturulup, ilk degerleri atanmaktadır. Baslangıç içinTürkiye’deki 81 ilin hepsi plaka kodlarına göre eklenmistir.

articles, connections ve events tablolarının hepsi bu tanım metodu içinde olusturulmustur.

Makaleler

Makaleler tablosu articles adıyla olusturuldu. articles ikisi üniversities ve users tablosunu referans veren sütun,biri birincil anahtar olmak üzere toplamda 6 sütundan olusur. Makaleler bir üniversiteye baglı mail adresi olan birkullanıcının beli bir yılda belli bir isimde çıkardıgı makaleleri tutar.

Yukarıdaki metotlar server.py dosyasında connections’a baglı metotlar tarafından connectionss.html‘de gerekliislemleri saglayabilmesi amacıyla kullanılıyor. Örnegin connections.html‘içindeki degiskenler, listeler bu se-kilde belirleniyor. connections.html de dıs anahtar ile referans verilen tablo verilerini checkboxlar’a eklemek içinusers tablosundan türetilen listeler kullanıldı. Diger metotlar klasik CRUD islemlerini gerçeklestirmek için kulla-nıldı(Güncelleme Hariç). server.py‘nin connections_page metodu connections.html ekranının ne sekilde hangiverilerle açılacagını kontrol eder.

Metotlar aracılıgıyla veri ve is akısını söyle sıralayabiliriz : init.py -> myconnections.py -> server.py -> connecti-ons.html

connections.html dosyasında da articles gibi accordion button tasarımını gerçekleyen javascript kod parçası kul-lanıldı. Ekranlarda kullanılan bu buton yapısına göre ilgili alan butonuna tıklayınca alt bölmenin açılması, aynıyere tıklayınca ya da baska bir alanın tıklanarak aktif edilmesiylede eski alanın kapatılması html dosyası içindebu kod yapısıyla saglanıyor.





Etkinlikler

Etkinlikler tablosu events adıyla olusturuldu. events ikisi locations ve users tablolarını referans veren sütunlar, biribirincil anahtar olmak üzere toplamda 6 sütundan olusur. Etkinlikler tablosu bir kullanıcının bir yerde belli birtarihte belli bir isimle ve belli detaylarla olusturdugu etkinlik verilerini tutar.

Python kısmında Job, Group ve Message sınıfları benim tarafımdan olusturuldu. Bu sınıfların kurucuları asagıdaverilmistir.

Sınıf kurucularında bulunan cp degiskeni database baglantısı saglanması için kullanılmaktadır. Bu sınıflardannesne olustururuken yapılacak islemin özelligine göre sınıfın degiskenleri kurucu methoda verilebilir ya da veril-meyebilir bu yüzden verilmesi veritabanı baglantısı için zorunlu olan cp degiskeni dısındaki degiskenlerin nesneolusturulurken verilmemesi ihtimaline karsı=None opsiyonu eklenerek bu degiskenler verilmediginde degerleriNone yapılmaktadır.

Güncelleme

Sayfada üçüncü ana öge olarak güncelleme arayüzü bulunur. Bu kısımda projects_page url’si ile sunucuya bagla-nılır ve veritabanından istenen ProjectList‘deki veriler bir for döngüsü ile Bootstrap stili form kutucuklarına yazılıolarak ekrana getirilir ve her bir satır sonuna Bootstrap stili bir buton eklenir. Kullanıcı, form kutucuklarına yazılıolarak getirilmis verilerde bir degisiklik yaptıgında o satıra ait güncelle butonuna tıklar ve form kutucuklarındakiveriler projects_to_update istemiyle sunucuya submit edilir.
