ABP Suite: How to Add the User Entity as a Navigation Property of Another Entity

Introduction

ABP Suite, a part of the ABP Commercial, is a productivity tool developed by the team behind the ABP Framework. The main functionality of the ABP Suite is to generate code for you.

In this post, I'll show you how to add the user entity as a navigation property in your new entity, by the help of the ABP Suite.

In the sample project MVC UI is used, but the same steps are applicable to the Angular UI as well.

Code Generation

Create a New Entity

Open the ABP Suite (see how). Create a new entity called Note, as an example entity.

create-note-entity

Then add a string property called Title, as an example property.

add-simple-property

Create AppUserDto

ABP Suite needs a DTO for the target entity (user, in this case) in order to define a navigation property.

To do this, create a new folder called "Users" in *.Application.Contracts then add a new class called AppUserDto inherited from IdentityUserDto.

create-appuserdto

We should define the object mapping to be able to convert the AppUser objects to AppUserDto objects. To do this, open YourProjectApplicationAutoMapperProfile.cs and add the below line:

CreateMap<AppUser, AppUserDto>().Ignore(x => x.ExtraProperties);

create-mapping

Creating such a DTO class may not be needed for another entity than the AppUser, since it will probably be already available, especially if you had created the other entity using the ABP Suite.

Define the Navigation Property

Get back to ABP Suite, open the Navigation Properties tab of the ABP Suite, click the Add Navigation Property button. Browse AppUser.cs in *.Domain\Users folder. Then choose the Name item as display property. Browse AppUserDto.cs in *.Contracts\Users folder. Choose Users from Collection Names dropdown.

Generate the Code!

That's it! Click Save and generate button to create your page. You'll see the following page if everything goes well.

final-page

This is the new page that has been created by the ABP Suite. It can perform the fundamental CRUD operations. Also, it has the "App user" column that shows the related user name (you can easily change the automatically created "App user" title from the Entity Name field of the navigation property creation screen).

Picking Users from Look Up Table

We used dropdown element to select a user from the user list. If you have a lot of users, then it's good to pick a user from a look up table. A look up table is a modal window that lets you filter data and pick one. To do this, get back to Suite and click Edit button of user navigation which is set as AppUserId name. Choose "Modal" from the "UI Pick Type" field. Then click Save and generate button to recreate your page.

After successful code generation, you'll see the the user can be picked from user table.
