Yeah, the “legacy” thought is what’s making me second guess the effort. We’re 
still in limbo with the language focus, IMO.

Are we nearing a change in routing? I remember work being demo’d at the last 
summit, but I haven’t seen any of it since.

Subject: Re: [openstack-dev] [horizon] URL Sanity

Interesting idea, and in general I'm for consistency. I can't speak directly to 
the network/port question, though it seems to me that if ports must be attached 
to networks then it makes sense for the URL to reflect that.

On the other hand, some could argue that the django URL routing is ... legacy 
... and shouldn't me messed with :)

On the gripping hand, thinking about this could inform future angular routing 
planning...

Hi all,

I recently started looking into properly implementing breadcrumbs to make 
navigation clearer, especially around nested resources (Subnets Detail page, 
for example). The idea is to use the request.path to form a logical breadcrumb 
that isn’t dependent on browser history ( 
https://review.openstack.org/#/c/129985/3/horizon/browsers/breadcrumb.py ). 
Unfortunately, this breaks down quite quickly because we use odd patterns like 
`<resources>/<resource_id>/detail`, and `<resources>/<resource_id>` doesn’t 
exist.

This made me realise how much of an inconsistent mess the URL patterns are.  
I’ve started cleaning them up, so we move from these patterns:

`/admin/networks/<network_id>/detail` - Detail page for a Network
`/admin/networks/<network_id>/addsubnet` - Create page for a Subnet

To patterns in line with usual CRUD usages, such as:

`/admin/networks/<network_id>` - Detail page for a Network
`/admin/networks/<network_id>/subnets/create` - Create page for a Subnet

This is mostly trivial, just removing extraneous words and adding consistency, 
with end goal being every panel following patterns like:

`/<resources>` - Index page
`/<resources>/<resource_id>` - Detail page for a single resource
`/<resources>/create` - Create new resource
`/<resources>/<resource_id>/update` - Update a resource

This gets a little complex around nested items. Should a Port for example, 
which has a unique ID, be reachable in Horizon by just its ID? Ports must 
always be attached to a network as I understand it. There are multiple ways to 
express this:

`/networks/ports/<port_id>` - Current implementation
`/networks/<network_id>/ports/<port_id>` - My preferred structure
`/ports/<port_id>` - Another option

Does anyone have any opinions on how to handle this structuring, or if it’s 
even necessary?

Regards,
Rob
