MVC# - Mongodb 2.0 dependency injection

Question

I’m starting a project using MVC 4 with Driver 2.0 of MongoDB. I’m used to using Ninject with EF6 and would like to know if there is such a thing as MongoDBor some example architecture standard for implementing it.

Ps: I’ve already found some examples using the old driver, but I’m implementing the new MongoDB.

Thank you.

Answer 1

Mongodb Driver Dependency Injection

The driver of MongoDB is strongly coupled or you will not be able to modify the driver’s functionality easily since it does not use external dependencies (you are certainly not trying to do this), if you intend to use the MongoDB through a dependency injection system you will need to implement or transfer objects based on the interfaces below:

Mongodb.Driver.Imongoclient: Interface responsible for specifying a mongodb client will give you access to database management methods (creating new databases, deletion and listing, obtaining a single database) Reference: http://api.mongodb.org/csharp/2.0/html/T_MongoDB_Driver_IMongoClient.htm

Mongodb.Driver.Imongodatabase: Interface responsible for specifying a mongodb collection will give you access to collection management methods (creation, deletion and listing, retrieval, renaming and command execution) Reference: http://api.mongodb.org/csharp/2.0/html/T_MongoDB_Driver_IMongoDatabase.htm

Mongodb.Driver.Imongocollection<>: Interface responsible for specifying Ngo document collections different from other interfaces the collections are generic or you will need to specify a type for the collections Ex: Imongocollection< Product> the collections will allow you access to the records through the methods of consultation, deletion, editing, insertion, among others. Reference: http://api.mongodb.org/csharp/2.0/html/T_MongoDB_Driver_IMongoCollection_1.htm

As for a Pattern to use, an example of the implementation of Repository Pattern with Mongodb:

public class Repository<T> : IRepository<T> where T : new()
{
    protected readonly MongoClient client;
    protected readonly MongoServer server;
    protected readonly MongoDatabase database;
    protected readonly MongoCollection collection;


    public Repository(MongoClient client, MongoServer server, MongoDatabase database, MongoCollection collection)
    {
        this.client = client;
        this.server = server;
        this.database = database;
        this.collection = collection;
    }

    // Exemplo de adição de novos elementos em uma coleção.
    public void Add(T entity)
    {
        this.collection.Save(entity);
    }
}
