Add weight to device type / device

Proposed functionality

Hi,

would it be possible to add a weight field (kg) to the Device Type and Device?

Use case

We can only fit a certain weight per rack, we would like to document this directly in Netbox.
For this it would be nice to have this at the Device Type, Device and afterwards as a view at the Rack.

If we add this, we should take the same approach that we do for storing cable length: Allow the user to specify both a value and a unit (e.g. kilograms or pounds), but also store the absolute weight in kilograms for ordering and filtering. This is because manufacturers may list a device's weight in only one unit or the other, and avoids requiring users to do conversions before entering the data into NetBox.

Yes that sounds good. That's exactly how it would be perfect.

We often have floor loading limitations where this feature would be very useful. Suggest weight is also added to the module type which adds to the total device weight. For larger chassis based equipment this will provide a more accurate weight per rack/cabinet. It also would be useful to track rack max. weight capacity (either a factor of the total rack make/model capacity or the floor's loading capacity) so the viewer can see the available weight capacity of the cabinet in a bar chart like you currently can with circuit power.

I think if we take this approach we should add weight fields only to the DeviceType and ModuleType models, and introduce a read-only weight property on device which reports the sum of the device type's weight and the weight of all modules.

My only concern is, if we are talking about floor load limits, a rack also adds to the overall weight.

Might it be better to have a weight field, with a weighs property to return the sum of any components.

This would allow you to have both a weight and a weighs on a rack, where weighs would return the sum of all devices weighs "property".
