Hello,
When I creating a Child Entity’s Child Entity in ABP Studio, I can select another Child Entity as the Master Entity for the new table. However, after clicking Save and Generation, the generated code throws an error.
The issue is that the generated Master Entity .cs file does not include a navigation property for the newly created table. As a result, when establishing the one-to-many relationship in DbContext, it fails due to the missing reference.
To resolve this, I have to manually add the navigation property in the Master Entity's extended file.
My question is:
Does ABP Studio not support creating a Child Entity’s Child Entity by default?
Or is there something I can do to prevent this issue from occurring?
-

Hi,
Unfortunately I couldn't reproduce the exact same issue.
Here some of questions to determine problem properly:
-
Which version of ABP Suite do you use? (Also your ABP version)
-
-
Did you add navigation manually in navigations tab? It should work without adding it

Hi
My ABP Studio and ABP Versions
-
ABP Studio: 9.0.4
-
ABP Framework: 9.0.4
My Case
I want to create a four-layer Master-Detail relationship.
-
Creating the second-layer entity was successful since it's a typical case in the ABP documentation.
-
However, when I tried to create the third-layer entity, the .cs file of the second-layer entity did not include a navigation property for the new table.
-
In this case, the third-layer entity's master entity is the second-layer entity, while the second-layer entity is also a child entity itself.
Manually Adding Navigation in the Navigations Tab
I tried to manually add the navigation property in the Navigations tab, but it showed an error message:
"The master entity can not be same with the navigation property."

Yes we reproduced it but the team isn't sure about supporting multi-level child entities. After decision is made, I'll inform you.
