# `Soundcheck.Check.Refactor.FormForChangeset`
[🔗](https://github.com/leonqadirie/soundcheck/blob/v0.1.0/lib/soundcheck/check/refactor/form_for_changeset.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 `normal` and works with any version of Elixir.

## Explanation

Flags forms built directly from a changeset assign
(`<.form for={@changeset}>`) instead of from `to_form/2`. A changeset
assign changes as a whole on every validation, so LiveView re-renders
the entire form; a `Phoenix.HTML.Form` from `to_form/2` lets it track
fields individually, and is what Phoenix's generators and `<.input>`
expect.

Before:

    assign(socket, :changeset, Accounts.change_user(user))

    <.form for={@changeset} phx-change="validate">

After:

    assign(socket, :form, to_form(Accounts.change_user(user)))

    <.form for={@form} phx-change="validate">

The check recognizes a changeset by name: an assign whose name ends in
`changeset`.

Confidence: medium. Tier: syntactic (works without compiling).

## Check-Specific Parameters

Use the following parameters to configure this check:

### `:excluded_paths`

  Paths to skip (atoms, binaries as path segments, or regexes).

*This parameter defaults to* `[~r/\/test\//, "test"]`.

### `:strict`

  Unused.

*This parameter defaults to* `false`.

## 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`).
