Bu i\u00e7eri\u011fimizde ise yine Mongoose mod\u00fcl\u00fc \u00fczerinden veritaban\u0131m\u0131zda \u015fema olu\u015fturmay\u0131 ve olu\u015fturdu\u011fumuz \u015femaya kay\u0131t eklemeyi inceleyece\u011fiz.<\/p>\n

Bizler bu makalede ele alaca\u011f\u0131m\u0131z y\u00f6ntemle Node.js ile programatik olarak kendi collectionlar\u0131m\u0131z\u0131 direkt olarak olu\u015fturacak ve bu collectionlara veriler ekleyece\u011fiz.<\/p>\n

Ad\u0131m 1<\/h3>\n

Model Olu\u015fturma<\/strong>
\nProjemizdeki modelleri ben genellikle projenin ana dizininde “models” isimli klas\u00f6rde tutmay\u0131 tercih ediyorum. “Models” klas\u00f6r\u00fc alt\u0131na yine ismini nacizane belirledi\u011fim “employee.js” ad\u0131nda bir model dosyas\u0131 olu\u015fturuyorum.<\/p>\n

\r\nconst mongoose = require("mongoose");\r\n\r\nmodule.exports = mongoose.model("Employees", new mongoose.Schem a({\r\n    name: String,\r\n    surName: String,\r\n    age: Number,\r\n    married: Boolean\r\n}));\r\n<\/pre>\nYukar\u0131daki kod blo\u011funu incelerseniz e\u011fer bir modelin nas\u0131l olu\u015fturuldu\u011funu g\u00f6rmektesiniz. Dikkat ederseniz require edilen Mongoose mod\u00fcl\u00fc \u00fczerinden “model” fonksiyonu geriye exports edilmektedir. Fonksiyonun ilk parametresi bu modelin veritaban\u0131nda hangi collectiona ait oldu\u011fu bilgisini tutmaktad\u0131r. \u0130kinci parametre ise Mongoose mod\u00fcl\u00fcnde bulunan Schema s\u0131n\u0131f\u0131nda bir nesne almaktad\u0131r. Haliyle g\u00f6r\u00fcld\u00fc\u011f\u00fc \u00fczere Schema nesnesi i\u00e7erisinde ilgili modelimiz tan\u0131mlam\u0131\u015f bulunmaktad\u0131r.

Bizler makalemizin ba\u015flar\u0131nda “CompanyDB” isminde bo\u015f bir veritaban\u0131 olu\u015fturmu\u015ftuk. Dolay\u0131s\u0131yla i\u00e7erisinde “Employees” isminde bir collection olmad\u0131\u011f\u0131n\u0131 biliyoruz. Yukar\u0131da olu\u015fturmu\u015f oldu\u011fumuz modeli birazdan gidip veritaban\u0131na ilgili isimde bir collection\u0131 manuel olarak tan\u0131mlamaya gerek kalmaks\u0131z\u0131n ekleyebilece\u011fiz ve bu i\u015flem neticesinde “Employees” collection\u0131 otomatik eklenmi\u015f olacakt\u0131r. Bu i\u015flemi Mongoose mod\u00fcl\u00fc MongoDB ile olan derin uyumlulu\u011fundan otomatik olarak ger\u00e7ekle\u015ftirecektir.<\/p>\n
Yukar\u0131da yapm\u0131\u015f oldu\u011fumuz model tan\u0131mlamas\u0131n\u0131 a\u015fa\u011f\u0131daki gibide yapabilece\u011fimizi bilmenizi isterim.<\/p>\n\r\nconst mongoose = require("mongoose");\r\n\r\nconst model = new mongoose.Schem a({\r\n    name: String,\r\n    surName: String,\r\n    age: Number,\r\n    married: Boolean\r\n});\r\n\r\nmodule.exports = mongoose.model("Employees", model);\r\n<\/pre>\nBu farkl\u0131 varyasyon tan\u0131mlamas\u0131ndan sonra ikinci ad\u0131ma ge\u00e7ebiliriz.<\/p>\nAd\u0131m 2<\/h3>\nModeli Kullanarak Instance Olu\u015fturma ve Veritaban\u0131na Kay\u0131t Etme<\/strong>
