The total number of components on the device tab displayed in the UI does not match the actual number.

[penM000]

NetBox version

v3.6.4

Python version

3.8

Steps to Reproduce

I know of two ways to generate this problem.

Method using front and rear ports

1. Create a device with a front port and a rear port.
2. Delete the rear port.
3. The front port is labeled 24, but no ports exist.
   
   
   

This phenomenon occurs with modules.

1. Create a module with various components.
2. module to the device.
3. component is increasing and confirms that it is indeed present.
4. Delete the module.
5. The Interface component has been removed, but the others (console port, power port, etc.) show that there are 32, even though the component is not present.
   
   
   
   
   

Expected Behavior

We expect the number of components to match the numbers displayed in the tabs.

Observed Behavior

Different numbers are displayed even though the component does not exist.

If one is added in the state of 32, the display becomes 33.
If I delete it, it just goes back to 32 and cannot be set to 0.
Please let me know how to fix this as well.

@penM000 you can run the management command calculate_cached_counts to recalculate the counters to the correct values. There is another bug #14081 that effects removing parent elements that is currently being worked on, but the management command will recalc it to show the correct values.

Thank you for your confirmation.
Thank you also for your help on how to correct the problem.
I am aware that this is similar to #14081. Is this ticket closed?

Closing as dupe of #14081
