Mounting the App

An App is an Interface over the Nouns, so its screens derive from them. Leaseline declares a Lease Noun, and the portal gives managers and residents their own screens.

What you buildCopy Anchor Link

You mount apps/portal/ at /app with two Personas: managers run every Verb, residents read and answer. Then you override one screen, the lease detail.

StepsCopy Anchor Link

1. 1

   To mount the App, write its folder file:

   Copy Text

   ---
   kind: saas
   mount: /app
   nouns: [Lease]
   personas:
     manager: { may: [Lease.create, Lease.renew, Lease.notify] }
     resident: { may: [Lease.get] }
   ---

2. 2

   To open the screens it derived, visit the preview at /app/leases, then one lease, then /app/leases/lease_4loEed1JG4/renew.

3. 3

   To change the lease screen, write a view at its path:

   Copy Text

   ---
   personas: [manager]
   ---
   <ThingDetail />
   <Timeline />
   <VerbSheet verb="Lease.renew" />
   <VerbSheet verb="Lease.notify" />

   In a view, ThingDetail and Timeline show the record its route names. Each VerbSheet turns one Verb into fields and a button, with its Mode, its Price and any Approval it needs.

ResultCopy Anchor Link

The portal serves a list and a record screen for leases and a form for each Verb, and residents see only what they may read. The view override replaced one screen and left the rest derived. Checkpoint leaseline@ch07 (status planned) adds apps/portal/.
