如何使用表单在rails5.2上运行trix-rails

gem 'trix-rails'

<%= form_with(model: @article) do |form| %>
  <%= form.label :title %>
  <%= form.text_field :title %>

  <%= form.label :content %>
  <%= form.trix_editor :content %>

  <%= form.submit %>
<% end %>

def create
  @article = Article.new(article_params)

  if @article.save
    redirect_to @article
  else
    render 'new'
  end
end

private

def article_params
  params.require(:article).permit(:title, :content)
end

class Article < ApplicationRecord
  has_rich_text :content
end
