# `Bylaw.Credo.Check.Ecto.NoRepoTransaction`
[🔗](https://github.com/ryanzidago/bylaw/blob/v0.1.0-alpha.1/lib/bylaw/credo/check/ecto/no_repo_transaction.ex#L1)

## Basics

> #### This check is disabled by default. {: .neutral}
>
> [Learn how to enable it](`e:credo:config_file.html#checks`) via `.credo.exs`.

This check has a base priority of `higher` and works with any version of Elixir.

## Explanation

Use `Repo.transact/1,2` instead of calling `Repo.transaction/1,2`
directly.

## Examples

Avoid:

      Repo.transaction(fn ->
        create_user!(attrs)
        create_audit_event!(attrs)
      end)

Prefer:

      Repo.transact(fn ->
        create_user!(attrs)
        create_audit_event!(attrs)
      end)

## Notes

`Repo.transaction/1,2` is deprecated in Ecto 3.13 in favor of
`Repo.transact/1,2`. Keeping deprecated calls around makes future Ecto
upgrades noisier and leaves new transactional code on the old API.

`Repo.transact/1,2` communicates the preferred Ecto API directly and
keeps transaction call sites off the deprecated API.

This check uses static AST analysis, so it favors clear source-level patterns over runtime behavior.

## Options

This check has no check-specific options. Configure it with an empty option list.

## Usage

Add this check to Credo's `checks:` list in `.credo.exs`:

```elixir
%{
  configs: [
    %{
      name: "default",
      checks: [
        {Bylaw.Credo.Check.Ecto.NoRepoTransaction, []}
      ]
    }
  ]
}
```

## Check-Specific Parameters

*There are no specific parameters for this check.*

## General Parameters

Like with all checks, [general params](`e:credo:check_params.html`) can be applied.

Parameters can be configured via the [`.credo.exs` config file](`e:credo:config_file.html`).
