When using namespaces, the 'default' namespace is a little special in
that we wanted the option for all our URLs to stay the same when using
namespaces if you are using the default namespace, with the option of
also being able to explicitly specify `~default` as a namespace.
In other words both `ui/services/service-name` and
`ui/~default/services/service-name` show the same thing.
This means that if you switch between OSS and Enterprise, all of your
URLs stay the same, but you can still specifically link to the default
namespace itself.
Our routing configuration is duplicated in order to achieve this:
```
- :dc
- :service
- :kv
- :edit
- :nspace
- :dc
- :service
- :kv
- :edit
```
Secondly, ember routing resolves/matches routes in the order that you specify
them, unless, its seems, when using wildcard routes, like we do in the
KV area.
When not using the wildcard routes the above routing configuration
resolves/matches a `/dc-1/kv/service` to the `dc.kv.edit` route correctly
(dc:dc-1, kv:services), that route having been configured in a higher
priority than the nspace routes.
However when configured with wildcards (required in the KV area), note
the asterisk below:
```
- :dc
:service
- :kv
- *edit
- :nspace
- :dc
- :service
- :kv
- *edit
```
Given something like `/dc-1/kv/services` the router instead matches the
`nspace.dc.service` (nspace:dc-1, dc:kv, service:services) route first even
though the `dc.kv.edit` route should still match first.
Changing the `dc.kv.edit` route back to use a non-wildcard route
(:edit instead of *edit), returns the router to match the routes in the
correct order.
In order to work around this, we catch any incorrectly matched routes
(those being directed to the nspace Route but not having a `~`
character in the nspace parameter), and then recalculate the correct
route name and parameters. Lastly we use this recalculated route to
direct the user/app to the correct route.
This route recalcation requires walking up the route to gather up all of
the required route parameters, and although this feels like something
that could already exist in ember, it doesn't seem to. We had already
done a lot of this work a while ago when implementing our `href-mut`
helper. This commit therefore repurposes that work slighlty and externalizes
it outside of the helper itself into a more usable util so we can import
it where we need it. Tests have been added before refactoring it down
to make the code easier to follow.
For URL maintenance reasons we store the last visited DC in
localStorage incase you come back to a page (for example settings) that
doesn't have a dc in the URL.
A problem arises here if the last DC you tried to visit is unreachable.
The first fix here clears out the last visited DC from localStorage if
the API has errored out.
Secondly, our `href-mut` helper which mutates the current current and
replaces 'parts' in the URL rather than the whole thing functioned by
detecting the current route/URL you are on an 'mutating' that. A problem
arose here as even though you might be on the `/ui/dc-1/services` URL the
actual route is the 'error' route which does not have a URL that can be
changed properly.
The second fix here uses route.currentRoute.name over route.currentRouteName.
The latter is equal to error when an error occurs whereas the former gives you the name of the route before the error happened, which is actually what we want/the intent here.
ie. when `router.currentRouteName === 'error'` then
`router.currentRoute.name === Name Of Route Before It Errored` it seems
* Remove empty init
* Actually make the disco chain endpoint send the nspace, note:
The backend doesn't support this as yet.
* Tweak the font size of flash-messages ever so slightly
* Make sure the nspace menu is kept up to date when creating a new one
* Move comment to the correct place
* Only refresh the namespace menu if you specifically created a nspace
* Change FIXMEs to TODOs as we are happy for these to wait until later
Adds namespace support to the UI:
1. Namespace CRUD/management
2. Show Namespace in relevant areas (intentions, upstreams)
3. Main navigation bar improvements
4. Logic/integration to interact with a new `internal/acl/authorize` endpoint
