dbt-autofix 0.12.0

CLI to autofix deprecations in dbt projects

dbt-autofix

dbt-autofix automatically scans your dbt project for deprecated configurations and updates them to align with the latest best practices. This makes it easier to resolve deprecation warnings introduced in dbt v1.10 as well as prepare for migration to the dbt Fusion engine.

Deprecation Coverage - Project Files

The following deprecations are covered by dbt-autofix deprecations:

Deprecation Code in dbt Core	Files	Handling	Support	Behavior Change
PropertyMovedToConfigDeprecation	YAML files	Move all deprecated property-level configs under config: in YAML files across all resource types (models, exposures, owners, etc)	Full	No
CustomKeyInObjectDeprecation	YAML files	Move all models extra config (not valid or custom) under meta: and meta under config:	Full	No
DuplicateYAMLKeysDeprecation	YAML files	Remove duplicate keys in YAML files, keeping the second one to keep the same behaviour	Full	No
CustomTopLevelKeyDeprecation	YAML files	Delete custom top-level key-value pairs in YAML files	Full	No
UnexpectedJinjaBlockDeprecation	SQL files	Remove extra {% endmacro %} and {% endif %} that don't have corresponding opening statements	Full	No
MissingPlusPrefixDeprecation	dbt_project.yml	Prefix all built-in configs for models/tests etc... with a +	Partial (Does not yet prefix custom configs)	No
ConfigDataPathDeprecation	dbt_project.yml	Remove deprecated config for data path (now seed)	Full	No
ConfigLogPathDeprecation	dbt_project.yml	Remove deprecated config for log path	Full	No
ConfigSourcePathDeprecation	dbt_project.yml	Remove deprecated config for source path	Full	No
ConfigTargetPathDeprecation	dbt_project.yml	Remove deprecated config for target path	Full	No
ExposureNameDeprecation	YAML files	Replaces spaces with underscores and removes non-alphanumeric characters in exposure names	Full	Yes
ResourceNamesWithSpacesDeprecation	SQL files, YAML files	Replaces spaces with underscores in resource names, updating .sql filenames as necessary	Full	Yes
SourceFreshnessProjectHooksNotRun	dbt_project.yml	Set source_freshness_run_project_hooks in dbt_project.yml "flags" to true	Full	Yes
MissingGenericTestArgumentsPropertyDeprecation	YAML files	Move any keyword arguments defined as top-level property on generic test to arguments property	Full	No

Deprecation Coverage - CLI Commands

The following deprecations are covered by dbt-autofix jobs:

Deprecation Code in dbt	Handling	Support	Behavior Change
ModelParamUsageDeprecation	Replace -m/--model with -s/--select	Full	No
CustomOutputPathInSourceFreshnessDeprecation	Remove -o/--output usage in dbt source freshness commands	Full	Yes

Installation

From PyPi

With uv (recommended)

We recommend using uv/uvx to run the package. If you don't have uv installed, you can install uv and uvx, following the instructions on the offical website.

• to run the latest version of the tool: uvx dbt-autofix
• to run a specific version of the tool: uvx dbt-autofix@0.1.2
• to install the tool as a dedicated CLI: uv tool install dbt-autofix

With pip

You can also use pip if you prefer, but we then recommend installing the tool in its own Python virtual environment. Once in a venv, install the tool with pip install dbt-autofix and then run dbt-autofix ...

From the source repo

To run it from the git repo directly, install uv following those instructions and then:

run the tool directly

uvx --from git+https://github.com/dbt-labs/dbt-autofix.git dbt-autofix --help

or install it so that it can be run with dbt-cleanup in the future

uv tool install --from git+https://github.com/dbt-labs/dbt-autofix.git dbt-autofix

Usage

deprecations - the main one

• dbt-autofix deprecations: refactor YAML and SQL files to fix some deprecations
  • add --path <mypath> to configure the path of the dbt project (defaults to .)
  • add --dry-run for running in dry run mode
  • add --json to get resulting data in a JSONL format
  • add --json-schema-version v2.0.0-beta.4 to get the JSON schema from a specific Fusion release (by default we pick the latest)
  • add --select <path> to only select files in a given path (by default the tool will look at all files of the dbt project)
  • add --include-packages to also autofix the packages installed. Just note that those fixes will be reverted at the next dbt deps and the long term fix will be to update the packages to versions compatible with Fusion.
  • add --behavior-change to run the subset of fixes that would resolve deprecations that require a behavior change. Refer to the coverage tables above to determine which deprecations require behavior changes.

Each JSON object will have the following keys:

• "mode": "applied" or "dry_run"
• "file_path": the full path of the file modified. Each file will appear only once
• "refactors": the list of refactoring rules applied

Calling deprecations without --dry-run should be safe if your dbt code is part of a git repo.

Please review the suggested changes to your dbt project before merging to main and make those changes go through your typical CI/CD process.

jobs

dbt-autofix jobs: update dbt platform jobs steps to use -s/--select selectors instead of -m/--models/--model which are deprecated in the Fusion engine

Run dbt-autofix jobs --help to see the required parameters and supported arguments.

This tool requires connecting to the dbt Admin API to retrieve and update jobs which means that the user token or service token used need to have Read and Write access to jobs

Running with --dry-run/d will output what changes would have been triggered without triggering them

Running with --behavior-changes will run the subset of fixes that would resolve deprecations that require a behavior change. Refer to the coverage tables above to determine which deprecations require behavior changes.
