Summary

Goal (CORE-1496): make --dbt-vars apply to every dbt command that edr runs on its internal dbt project, not just the alerts_v2 run in edr monitor.

Changes for the goal

  1. Runner-level vars. The vars are parsed once, stored on Config.dbt_vars, and set when the internal runner is built. Every run/run_operation on that runner then gets them; per-call vars still override them.
    # clients/dbt/factory.py
    def create_dbt_runner_from_config(config, project_dir, force_dbt_deps=False):
        return create_dbt_runner(project_dir, config.profiles_dir, config.profile_target,
                                 env_vars=config.env_vars, vars=config.dbt_vars,
                                 run_deps_if_needed=config.run_dbt_deps_if_needed,
                                 force_dbt_deps=force_dbt_deps)
    These call it with CLI_DBT_PROJECT_PATH:
    • DataMonitoring._init_internal_dbt_runner (monitor, report, send-report)
    • Debug.run
    • UploadSourceFreshnessOperation.upload_results
  2. --dbt-vars on every command that uses the internal project: monitor, report, send-report (via common_options), monitor debug and run-operation upload-source-freshness. The option is a shared dbt_vars_option in utils/cli_utils.py.

Changes needed to support the goal

  1. days_back is now a runner var. alerts_v2 reads var('days_back', 1). Before, it got days_back as a per-call var in _populate_data. Now Config adds it to dbt_vars, and _populate_data passes no per-call vars:
    self.dbt_vars = dbt_vars
    if days_back:
        self.dbt_vars = self.dbt_vars or {}
        self.dbt_vars["days_back"] = days_back
    • --days-back overrides a days_back passed in --dbt-vars.
    • --days-back 0 is still dropped, as before. With 0, the populate macros select nothing, while the fetch still looks at alerts since midnight.
    • run_alerts(days_back, ...) still uses days_back to fetch pending alerts and last-sent times. It no longer takes dbt_vars.
  2. Parsing in the callback. The option's callback parses the YAML into a dict and returns None when the option is omitted. Invalid YAML, or a value that isn't a mapping, now fails with a usage error (exit 2). Before, it crashed or passed a string to dbt as vars.
  3. Side effect: Debug and UploadSourceFreshnessOperation now also get config.env_vars. That's always {} for them because they have no --dbt-quoting option, so behavior doesn't change.

Out of scope

  • dbt-init and the user-project runner in SelectorFilter._create_user_dbt_runner, same as the ticket.
  • edr monitor --dbt-vars X report ignores the value given before the subcommand, like every other monitor option. Use edr monitor report --dbt-vars X instead.
  • YAML dates in --dbt-vars (e.g. {as_of: 2026-10-06}) still raise TypeError in the runner's json.dumps. master behaves the same way.

Tests

tests/unit/cli/test_dbt_vars_option.py:

  • checks config.dbt_vars for each command;
  • covers how --days-back and --dbt-vars combine, including a conflict and --days-back 0;
  • checks that invalid YAML and non-mapping values are rejected.

Summary by CodeRabbit

  • New Features
    • Added --dbt-vars support to monitoring, reporting, debugging, and source-freshness commands, accepting YAML mappings.
    • Added a days_back setting for controlling the monitoring lookback period; it can also be set through dbt variables.
  • Bug Fixes
    • Invalid YAML or non-mapping values for --dbt-vars now produce a clear command-line error.

📝 Walkthrough

Walkthrough

The CLI now shares dbt-vars parsing across affected commands and stores the parsed mapping in Config. Monitoring, debug, and source freshness operations use a shared internal dbt runner factory. Alert execution no longer accepts caller-supplied dbt variables.

Merge Risk: 🔵 Low · up to b6293

Unquoted YAML dates in --dbt-vars can make the newly supported report, send-report, debug, and source-freshness commands fail before dbt runs. Quoting a date as a string is a workaround; this is a narrow edge case rather than a broad merge blocker.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Validate dbt vars before passing them to the runner.

For --dbt-vars '{as_of: 2026-10-06}', the YAML loader produces a date value. This check accepts the mapping, but the internal runner’s json.dumps(all_vars) raises TypeError when a newly supported command runs dbt. Normalize supported YAML values to JSON-compatible values, or return click.BadParameter before starting the command. (raw.githubusercontent.com)

@coderabbitai Re the outside-diff cli_utils.py:46-50 finding about date values: confirmed. --dbt-vars "{as_of: 2026-10-06}" loads a date and the runner's json.dumps raises TypeError. edr monitor on master behaves the same way. I'm checking with the PR owner whether to normalize dates to ISO strings here (as the closed #2374 did) or in a follow-up, and have left the code unchanged for now.

@devin-ai-integration[bot] Thanks for the clarification. _parse_dbt_vars returns the YAML mapping without normalizing date values, which is consistent with your reproduction.

This is an existing limitation, not a regression introduced by this PR. The finding remains unresolved while the PR owner decides where to fix it.

If the owner chooses a follow-up, would you like me to open a GitHub issue?

Timestamp: 2026-10-06T13:14:38.888Z
Learning: In elementary-data/elementary, YAML date values in --dbt-vars, such as "{as_of: 2026-10-06}", become Python date objects and cause the dbt runner's json.dumps to raise TypeError. The PR #2375 author confirmed that edr monitor on master has the same behavior, so this is a pre-existing limitation rather than a regression introduced by PR #2375.

@EladBarkay I updated the PR description so it matches the code as of b629331, including the changes from review. The full list is under "What changed"; the ones from review are:

  • days_back moved into Config.
  • The factory became create_dbt_runner_from_config.
  • _populate_data no longer passes per-call vars.
  • --days-back 0 still falls back to the default.
  • The runner-wiring test file was removed.

the description is not focused on the actual PR scope and goal. what changed should first specify things related to the PR goal, then changes made because they were needed / make sense for this change, by importantly order

@EladBarkay I reorganized the description:

  1. The goal comes first.
  2. Then the changes that implement it: runner-level vars through create_dbt_runner_from_config, and the option on each command.
  3. Then the changes needed to support it, most important first: days_back as a runner var, YAML validation, the env_vars side effect.
  4. Then what's out of scope and the tests.
