    Using Autofac - how to inject / use DatabaseContext

    I've started using Autofac and separated my "services" with the goal I can write unit tests. Some services need to access custom DB tables. What's the best practice for accessing / using the Umbraco DBContext?

    I have something like: enter image description here

    But obviously that's not going to be right for unit tests? Do I need some kind of factory / wrapper. Does anyone have any examples of how to do this?

    Thanks in advance, Dave

    Hi Dave,

    You should just need to register the DatabaseContext with Autofac container and then put it as a parameter to your constructor.

    builder.Register(ctx => ApplicationContext.Current.DatabaseContext).ExternallyOwned();

    Hi Tom,

    Brilliant - thanks! That seems to work though I'll confess I'm lost how it's injecting it!

    To anyone who finds themselves here it just then needed injecting as

    public ClientsDataRepository(DatabaseContext databaseContext)
                //todo: this is not great?! needs a wrapper so I can inject it? 
                //_db = ApplicationContext.Current.DatabaseContext.Database;
                _db = databaseContext.Database;

    Hi Dave

    Can you provide a little more context into how you used this?
