Strange behavior with code blocks using form helpers and Slim

[javierav]

Hi!

I'm playing with this project for use in production but I encountered a possible bug related with passing a Slim/HTML block to Rails helper.

# app/components/test_component.rb

class TestComponent < ActionView::Component::Base
  def initialize(form:)
    @form = form
  end

  attr_reader :form
end

/ app/components/test_component.html.slim

div
  = form.text_field :name
  = form.label :name do
    div.label__text
      | Nombre

/ app/views/tests/show.html.slim

= form_with model: @test do |form|
  /! Test Component Start
  = render TestComponent.new(form: form)
  /! Test Component End

Expected output:

<!-- Test Component Start -->
<div>
  <input type="text" name="test[name]" id="test_name">
  <label for="test_name">
    <div class="label__text">Nombre</div>
  </label>
</div>
<!-- Test Component End -->

Current output:

<!-- Test Component Start -->
<div>
  <input type="text" name="test[name]" id="test_name">
  <div class="label__text">Nombre</div>
  <label for="test_name">
    <div>
      <input type="text" name="test[name]" id="test_name">
      <div class="label__text">Nombre</div>
    </div><!-- Test Component End -->
  </label>
</div>

In normal Rails the block of code passed to the helper works perfectly. Any ideas? Thanks!

This looks really similar to the issue I ran into that caused me to open #240.

Just ran into this and for a simple case temporarily solved it by doing

<%# 
  <% label_contents = '
    <span class="form-file-text">Cambiar imagen</span>
    <span class="form-file-button">Abrir</span>
  ' %>

  <%= @form.label(@attached_method, raw(label_contents), class: "form-file-label") %>

It seems that this error is happening with link_to code blocks and tag.<tagname> blocks too.

Any reason why this is happening?
