 <div id="newtask-form>"
 <%= form_with model: [@categories,@categories.tasks.build] do |form| %>
 <% if task.errors.any? %>
 <div id="error_explanation">
  <h2><%= pluralize(task.errors.count, "error") %> prohibited this task from being saved:</h2>

  <ul>
  <% task.errors.each do |error| %>
         <li><%= error.full_message %></li>

This is my task controller .

def new
@categories = current_user.categories.find(params[:category_id])
@task = Task.new
end


 def edit
 @categories = Category.find(params[:category_id])
 @task = Task.find(params[:id])
 end


 def create
  @category = current_user.categories.find(params[:category_id])
  @task = @category.tasks.build(task_params)
  @task.user_id = current_user.id

  if @task.save
    redirect_to categories_path
  else
    redirect_to category_path
  end

I run this code and it does not give me any error . When i click submit , nothing happens . no error its just really nothing happen .

I see about its being handle by javascript . I didn't touch anything in Javascript and we dont use javascript for now . Need assistance , presentation will be later
