Accrue.Billing.SubscriptionProjection (accrue v1.1.1)

Copy Markdown View Source

Translates a processor subscription response into local Ecto changesets.

A "projection" in Accrue means decomposing a processor subscription response into a flat attrs map that Accrue.Billing.Subscription accepts. This module handles type coercions, provider-specific lifecycle fields, and data normalization for round-trip safety.

Handles both the atom-keyed shape produced by Accrue.Processor.Fake and the string-keyed shape produced by remote adapters. Callers may pass processor: :stripe | :paddle | ... to force a specific projection mode; otherwise the configured processor name is used.

Summary

Functions

decompose(subscription, opts \\ [])
to_string_keys(dt)

Recursively converts atom-keyed maps to string-keyed maps and DateTimes to ISO8601 strings so the result is jsonb round-trip safe.

Functions

decompose(subscription, opts \\ [])

@spec decompose(
  map(),
  keyword()
) :: {:ok, map()}

to_string_keys(dt)

@spec to_string_keys(term()) :: term()

Recursively converts atom-keyed maps to string-keyed maps and DateTimes to ISO8601 strings so the result is jsonb round-trip safe.

Public so Accrue.Billing.InvoiceProjection can reuse the same normalization rather than storing atom-keyed data and getting shape drift on reload.
