aeat.application.modelo._decimal_parsing module¶
Shared string-to-Decimal parser for borrador-sourced modelo bindings.
This module is a parsing helper, not a binding: decimal_from_string()
coerces a raw string into a Decimal for a registry binding
identifier. It is named for what it does (parsing) rather than the pipeline that
consumes it, so “binding” stays reserved for the registry-data-input concept.
The borrador-binding path accepts live snapshot values as either
Decimal or str. Its resolver keeps that boundary
local and delegates only the string coercion here. Profile-sourced bindings use
typed profile facts directly and keep their Decimal-channel refusal in the
profile resolver instead of reusing this raw-string helper.

aeat.application.modelo._borrador_binding.resolve_modelo_100_borrador_bindings()Consumes this helper after registry eligibility and caller-precedence checks decide that a borrador snapshot may supply the value.
aeat.application.modelo._profile_binding.resolve_profile_sourced_bindings()Resolves the same registry binding channels from typed profile facts, without raw string parsing.
The caller supplies the pipeline-specific error factory so the operator-facing refusal keeps the boundary context of the surface that found the bad value.
- decimal_from_string(binding_id, value, *, error_factory, pipeline_label='value')[source]¶
Parse a stripped string as a Decimal or raise the pipeline-specific error.
- Parameters:
binding_id (
TypeAliasType) – Registry binding identifier being resolved; appears in the error message so the operator can locate the offending value.value (
str) – Free string from a source pipeline such as a live borrador snapshot.error_factory (
Callable[[str],Exception]) – Callable invoked with the formatted message when the string does not parse. Each pipeline supplies its own boundary error class so refusals carry the right context; the factory may use the message directly or translate it into structured context.pipeline_label (
str) – Operator-facing label that prefixes the refusal message (for example,"borrador value"); defaults to the generic"value".
- Return type:
- Returns:
The parsed
Decimal.- Raises:
Exception – Whatever
error_factoryproduced.
