The code will store options for parents in ViewData. Private void SavePotentialParentsInViewData ( Person person = null ) The views generated by Visual Studio are not optimal for the fields Father and Mother if you want to create or edit people, so let’s change them to drop-down boxes. Important: this code adds a table for the children, and populates it with a foreach-loop. Mother: + " " + )ĭetails ( != null)Ĭhildren First name Last name Birth date Death date (var item in Model.Children) No information about parents available ( != null)įather: + " " + )ĭetails ( != null) For best practice, separate code you edit yourself from generated code, so when you rerun the scaffolding, it will only change files within the folder ModelsGenerated, but not in the Models folder. Let’s add data about, and navigation links to, parents and children via a new class in the PersonViewModel (find it in the Models folder). Most of the pages are complete, but the page to view a person is missing some critical information. Now, you are ready to run the first version of the application by pressing F5. Run these SQL statements in the SQL Query text box:

You won’t actually use data_owner_id in this tutorial, but at the end of this post, an explanation of how to maintain separate data for each user will use this field. The fields father and mother refer to the id of another row in the table. first name and last name are text fields, while the birth date and death date are dates. It has an integer field id, which populates automatically from the database when a new row is inserted.

You can also easily download and install PostgreSQL locally on your computer. offers free managed PostgreSQL for up to 5 concurrent connections and 20 Mb data, so it’s perfect for this sample app. Let’s get started! Create a PostgreSQL Instance We will then tailor the app to the specific requirements of a family tree builder. EntityFramework Core will scaffold the model and data access code, while Visual Studio will add the basic CRUD functionality. To show how Entity Framework uses the domain model to interact with databases directly from data model objects, we will use Entity Framework Core to build a Family Tree app and create a person table in PostgreSQL. It reduces the amount of data access code developers need to write, and offers higher-performance APIs. Furthermore, Entity Framework’s design makes it particularly friendly for PostgreSQL developers.Įntity Framework (EFCore) Core is a lighter weight and more flexible version that specifically enables.
