RuboCop cops

Two shipped cops keep call sites on the phlex-forms API — one autocorrects.

Setup#

.rubocop.yml

require:
  - phlex_forms/rubocop
inherit_gem:
  phlex-forms: config/rubocop.yml

PhlexForms/RawForm#

Flags form_with/form_for and raw Phlex form(...) calls in components, autocorrecting to Form(...) so every form gets the derived action/method, CSRF handling, and the builder API:

# bad
form(action: users_path, method: :post) { ... }

# good (autocorrected)
Form(url: users_path, method: :post) { |f| ... }

Flags Rails-FormBuilder-style calls (f.text_field, f.select, f.check_box, …) in favor of f.field and the PascalCase component methods — the biggest lever when migrating an app off a vendored builder:

# bad
f.text_field :email
f.check_box :terms

# good
f.field :email          # or f.Input(:email) for the bare control
f.Checkbox(:terms)
