How to make .sqlfluff customizations reflected in git commit run #5136

Search before asking

What Happened

Rules that were picked up by local .sqlfluff customization are not picked up during git commit execution. The following bug report may be a little close to my report. https://github.com/sqlfluff/sqlfluff/issues/4304

I've written this at length, but as I mentioned in the title, if I could figure out how to customize the sqlfluff rules that are applied when a git commit is executed, I think I could solve this problem.

Expected Behaviour

The same content that is locally linted can be detected in a git commit.

Observed Behaviour

As stated in the title. Errors in lint displayed when running with .sqlfluff differ from errors when running with commit

Created files

.pre-commit-config.yaml

repos:
- repo: https://github.com/sqlfluff/sqlfluff
  rev: 2.3.0
  hooks:
    - id: sqlfluff-lint

      additional_dependencies : ['dbt-bigquery==1.6.0', 'sqlfluff-templater-dbt']
      log_file : 'true'

sample sql(orders_payments.sql)

target_date is defined in dbt_project.yml

SELECT 
  c.id, 
  c.first_name
  ,c.last_name, 
  SUM(p.amount) AS total_amount
FROM 
  {{ source('main', 'raw_customers') }} AS c
INNER JOIN 
  {{ source('main', 'raw_orders') }} AS o 
ON 
  c.id = o.user_id
INNER JOIN 
  {{ source('main', 'raw_payments') }} AS p 
ON o.id = p.order_id
{% if  target.name == "duck" %}

WHERE 
    order_date::date = '{{ var('target_date') }}'::date

{% else %}

WHERE order_date = '{{ var('target_date') }}'
{% endif %}
GROUP BY 
    c.id, c.first_name, c.last_name

Verification results

First, let the linter run manually, and the following message will be returned

How to reproduce

  1. Create the model (at this time, I dare you to catch the error you are setting in .sqlfluff)
  2. Create .sqlfluff and .pre-commit-config.yaml files
  3. Run lint using .sqlfluff
  4. Execute add and commit without making any changes

Additional Verification

Change the contents of .sqlfluff to simple rules

[sqlfluff]
templater = dbt
max_line_length = 100
; rule = core
dialect = bigquery
rules = LT01

[sqlfluff:templater:dbt]

indented_using_on = True

[sqlfluff:layout:type:comma]

I also have the same issue, When running sqlfluff lint from CLI, I get all the warnings. However during pre-commit, the hook passes.

toshifumisuga commented 4 months ago

At that time, I didn't perform the validation specifying .sqlfluff in the argument. However, when I tried it in a different environment, I received an error saying the path could not be found. If I change it to an absolute path, then I get a different error...

Additional verification details I was able to solve the problem by using git diff on GitHubActions side, so I implemented it there and achieved something close to what I wanted to do. I'll leave this as a note in case anyone else comes across this page.
