Defined in:
app/models/spree/calculator/shipping/doordash_quote.rb

Overview

Prices a "DoorDash Delivery" shipping method against a real, live DoorDash Drive quote rather than a flat/configured rate. Spree::Stock::Estimator calls calculator.compute(package), which Spree::Calculator#compute dispatches to compute_package by demodulizing the argument's class name (Spree::Stock::Package -> "package") — no override of #compute itself needed.

Instance Method Details

#available?(package) ⇒ Boolean

Called by Estimator to filter which shipping methods even attempt a compute_package call. Skips the DoorDash API round-trip entirely for an order with no ship address yet (early checkout, before Estimator would sensibly be asked at all) — the real "can DoorDash serve this address" check still happens inside SpreeDoordash::Quote itself (compute_package returning nil is what actually makes the rate not show up).

Returns:

  • (Boolean)

    # "unavailable" nil, deliberately, so this stays generic to *why*)

    # anywhere in the UI. Spree::Order#warnings is the same
    # transient, request-scoped mechanism core's own
    # `ensure_available_shipping_rates` already uses for the
    # identical class of problem (a line item that can't ship at
    # all) — it flows through to the Store API's `cart.warnings`
    # with no new API surface needed. The storefront renders its own
    # localized copy for this code; `message` here is English-only,
    # a fallback for any other API consumer, not the UI text itself.
