Join Jess Chadwick for an in-depth discussion in this video Write to a database using Entity Framework, part of Learning ASP.NET Core MVC.
- [Instructor] Now that we've created…and configured our new data context class,…I'll show you how to put this new class to good use…by storing and retrieving the blog post…for our demo application.…Since we've already done all of the dirty work…of creating and configuring the data context class,…all that's left is to simply inject it into our controllers.…So, let's open up our blog controller again…and start by injecting a instance…of the blog data context class into the constructor.…Now that we have that, I can add the following lines…to the create action to save the newly…submitted post to the database.…
Notice how saving the post to the database…is a two step process.…Entity Framework works on the Unit of Work pattern,…which is really just a fancy way of saying…that first you tell the data context everything…that you want to do.…For example, adding a new post to the database.…Then, the second step is to tell the data context…to actually go ahead and execute what you've asked for,…which we do by calling the save changes method on line 76.…
