Modifying datacenterasset view #3419

Using Ralph
1

Hi all,
what is the preferred way to modify the datacenterasset view, e.g. at
http://example.org/data_center/datacenterasset/
I’d like to have less/other fields visible.
Thanks!

Hi
If you want to have less or other fields visible.
Only modify the field list in source code.(ralph/src/ralph/data_center/admin.py)

@register(DataCenterAsset)
class DataCenterAssetAdmin(
・・・
・・・
・・・
fieldsets = (

If you don’t want to loose updates, the recommended way is to hide it through permissions.
It will disapper from GUI from the user perspective.

Thanks guys, I found the relevant parts of the code! I fiddled with the rights system, but I quickly produced something non-usable the last time. An ability to not see parts of ralph that you don’t want to use would be nice. (e.g. IMEIs…) This could be done exploiting the existing rights system, I think.
