EF Core optimistic concurrency: add a rowversion token with an additive migration

Shows how to add optimistic concurrency to an existing EF Core entity with a SQL Server rowversion column in one additive migration, deploy it expand-first, and handle DbUpdateConcurrencyException. Use when existing rows must keep working, old code must run against the new schema, and lost updates must stop. Not for P…

Public published document approval audit history projection exclude pending drafts private review notes

Shows how to build a public audit history projection for document approvals that cannot leak private review notes: filter at projection time on both document status and event visibility, store the public read model in a separate table with no private columns, and handle unpublish, rebuilds and counts. Use when exposin…

Read-only service API scoped tokens modular least privilege published content filtering user privacy presence data

Shows how to design a read-only service API with modular least-privilege scopes: one scoped service token per module, read-only enforcement at route, scope and data layers, published-only filtering inside the base query, allowlist response projection for user privacy, and coarse opt-in handling for presence data. Use …

schema validation failed error: missing required column customer_id

A missing required column is a contract break, not a data error: confirm whether customer_id was renamed, dropped, or never delivered in the latest load, then restore it at the source or update every consumer and the contract together if the rename is intentional. Use when a schema validation failing because customer_…

dbt run error: test failed in manifest with schema change detected error

Read the manifest diff before rebuilding: a schema change detected error means the built model's columns no longer match what the manifest or contract recorded, so compare the model SQL's output columns with the recorded schema, then either restore the dropped or renamed column or update the contract and downstream re…

great expectations validation failed error: column type mismatch string vs int

Align the types before validating values: compare the column type in the warehouse information schema with the type the expectation assumes, find where values are written as strings, and cast at the model layer or fix the writer. Use when a Great Expectations validation reporting a string versus int type mismatch. Not…

how to fix schema drift failure: column renamed upstream breaks dbt model error

A renamed upstream column breaks every model that selects the old name: find the new name by diffing the source schema, update the source definition and the affected models, and add a compatibility alias during the transition if other consumers still use the old name. Use when dbt models breaking after an upstream col…

when agent tried to fix schema drift it broke downstream model error failed

Before applying any schema-drift fix, build the downstream impact list first: find every model, dashboard, and check that reads the changed column, then fix drift by adding compatibility, such as a renamed column kept alongside the old one, instead of renaming in place. Use when an agent repairing schema drift in a pi…

schema drift error: new column added upstream failed downstream schema check

A new upstream column breaks downstream checks that assert an exact column set: diff the upstream table schema against the schema the downstream check expects, decide whether the new column should flow through, be ignored, or be explicitly excluded, and update the contract in one place. Use when a downstream schema ch…
