Can you play with the filters and see what role causes the issue?

[mumaritc]

Filter for Show Unconnected devices is causing the issue, unchecking it will open the topology views, but no devices or view is showing

I´ve got the same bug. I changed the Role images and can´t open the Topology view. I removed all filters and the topology view will open now but don´t show anything.

I also can´t change the picture again. If I click the button an error message will appear:

If I activate some filters this error Message will appear by opening the topology view:

The console in my browser display this error message:

I hope this will help to fix the error.

Thanks for your report. Can anyone of you show the content of the table 'netbox_topology_views_roleimage'?

You can use dbshell for this task:

1. Activate your venv: source "path_to_your_venv_folder/bin/activate
2. python "path_to_your_netbox_folder"/netbox/manage.py dbshell
3. select * from netbox_topology_views_roleimage;

3. select * from netbox_topology_views_roleimage;

Hello deng,

of course. I´ve did a screenshot.

My guess is that I have to delete the double entries right? But why were they created multiple times? is that a bug?

[mumaritc]

Hello deng,

3. select * from netbox_topology_views_roleimage; content

The numbers in column "object_id" should be unique. It is save to delete any rows in that table. Just use dbshell:

delete from netbox_topology_views_roleimage where object_id = OBJECT_ID_TO_BE_DELETED;

I don't know what caused this situation. The object_id belongs to the role id. Have you deleted one or more roles and added new roles after that?

I changed your command a bit. I used:
delete from netbox_topology_views_roleimage where id = ID_TO_BE_DELETED;

with this command I can just delete the duplicates and I don´t need to save the images again (Reduce the risk to run again in this bug).

I don't know what caused this situation. The object_id belongs to the role id. Have you deleted one or more roles and added new roles after that?

I dind´t changed anything at the role names. I just selected the images for the roles, hit the save button and after that the error Message occured. It was a bit strange but now I know how to fix this issue. Thank you a lot.

I played around a bit and I couldn't reproduce such a situation. I created new roles, assigned images, deleted some roles... the table was always in a correct state.

@mumaritc Have you got any hints what may have caused this situation?
