Create Lease Keeper Processing for Store/Chain Population

Source code reference location

The CreateLease method within node/x/market/keeper/keeper.go takes in Bid details as an argument and writes the new Lease to the blockchain.

func (k Keeper) CreateLease(ctx sdk.Context, bid types.Bid) {
    store := ctx.KVStore(k.skey)

    lease := types.Lease{
        LeaseID:   types.LeaseID(bid.ID()),
        State:     types.LeaseActive,
        Price:     bid.Price,
        CreatedAt: ctx.BlockHeight(),
    }

    // create (active) lease in store
    key := keys.LeaseKey(lease.ID())
    store.Set(key, k.cdc.MustMarshal(&lease))

    ctx.Logger().Info("created lease", "lease", lease.ID())
    ctx.EventManager().EmitEvent(
        types.NewEventLeaseCreated(lease.ID(), lease.Price).
            ToSDKEvent(),
    )

    secondaryKeys := keys.SecondaryKeysForLease(lease.ID())
    for _, secondaryKey := range secondaryKeys {
        store.Set(secondaryKey, key)
    }
}
