how to delete an Express Data Object from within the Dashboard

Permalink
for testing purposes I created some Data Objects from within the Dashboard (so not programmatically).

Is there a way to delete these Data Objects also from within the Dashboard?
If not, can I safely remove the concerning row in the ExpressEntities database table or will it cause C5 to crash somewhere?

From your screenshot, click on the object you want to delete. It'll take you to your Objects details, where you set it up and add the attributes and all.

There click on "edit entity" in the left-hand menu and you'll get a "delete" button in the bottom left-hand corner

Thank you mnakalay,

it's as simple as that. I feel almost embarrassed that I didn't find that big red delete button myself :) That's why I'll mark this answer directly as Best Answer.

But I still have a problem deleting some objects. I have two objects that I can't delete, because the site encounters an error when I click "Edit entity" or "View ..Entries". The other options in the Object details menu are still accessible (e.g. Details, Associations, Forms...).

The "Edit Entity" page encounters a failure on loading
…/single_pages/dashboard/system/express/entities/edit.php78 (see screenshot)
for " Error Call to a member function getTreeNodeID() on null"

and the "View ... Entries" page encounters a failure on loading
…/src/Page/Controller/DashboardExpressEntriesPageController.php76
for " Error Call to a member function populateDirectChildrenOnly() on null"

Probably during testing of these objects I messed up something. Now I want to delete them, but in order to delete I have to be able to access the "Edit Entity" page and it's this page that can't be loaded.

In the database table "Treenodes" I can find the rows for the objects that I can delete, but I don't see a row for the two objects I can't delete. Duplicating such a row and changhing the name of the object to delete in the column treeNodeName doesn't help.

How can I make this object editable and/or deletable again?
Thanks!

Try refreshing your database entities. You can do that by navigating to your dashboard page /dashboard/system/environment/entities

When that's done, trying deleting your objects again.

That doesn't help. Still the same error:

Express / View Entries gives for these 2 objects:
"Error
Call to a member function populateDirectChildrenOnly() on null"

and
System&Settings / Express / Data objects / [the concerning object] / Edit Entity still gives this error:
"Error
Call to a member function getTreeNodeID() on null"

even after Refreshing Entities in System / Environment / Database Entities.

However, I can't reproduce this error, because when I create a new object , I can delete it now. Only those 2 objects with which I did some testing I still can't delete. I'll post back here if it occurs a third time and I found out how to reproduce it.
