No error message is displayed when create action fails

Background of the problem

The background is as the title. I was able to save it without any problems, but when the save failed, no error message was displayed and I was having a hard time. (Partial code excerpt)

laundries_controller.rb

def create
  @laundry = Laundry.new(laundry_params)
  if @laundry.save
    redirect_to root_path
  else
      render :new
  end
end

ruby:new.html.erb

<%= form_with model:@laundry, url: laundries_path, locals: true do |f| %>
  <%= render 'error_messages', model: f.object %>

Conclusion

There was an error in the description of the view file. Positive

local: true

Wrong

locals: true

The error statement was displayed safely by correcting the description to the correct one. The error message was not displayed correctly because the communication was asynchronous due to a description error. By the way, `locals``` can define variables used in partial templates with the option of `render``` method. It's only one letter difference, but the difference changes the behavior, so I realized that I had to be careful.

Digression

I want to display the code when creating an article, but it does not go well and I have a hard time ... When displaying the code, you have to leave blank lines before and after the backticks. I felt it was important to remember while actually moving my hands.
