user
Here's a simple tutorial on creating a ToDo app in Rails 7 with PostgreSQL as the database. This app will display a list of 5 items, and each item can be completed by clicking a checkbox.

Step 1: Set up a new Rails app
```sh
rails new todo_app --database=postgresql
```
This command will create a new Rails 7 app called `todo_app` with PostgreSQL as the database.

Step 2: Generate a model and migration for the ToDo item
```sh
rails generate model ToDo title:string completed:boolean
```
This command generates a new model, `ToDo`, with two fields: `title` and `completed`. The `title` field will hold the name of the item, and the `completed` field will be a boolean value indicating whether the item has been completed or not.

Next, we need to create a migration to add the `ToDo` model to the database schema. Run the following command:
```sh
rails db:migrate
```
Step 3: Generate controllers and views for the ToDo app
```sh
rails generate controller ToDos index show
```
This command generates a new controller called `ToDos` with actions `index` and `show`. The `index` action will display the list of 5 ToDo items, and the `show` action will display the details of a single ToDo item.

Next, we need to create the views for the ToDo items. Remove the default `index.html.slim` and `show.html.slim` files, and create the following files:

* `app/views/todos/index.html.slim`
```html
px-3
  h1 To Do List
  each todo in @todos
    .todo
      h2 = link_to "(#{todo.title})", show_todo_path(todo)
      if todo.completed?
        %input#todo_checkbox{:type=>"checkbox", :name=>"todo[#{todo.id}]", :checked=>"checked"}
      else
        %input#todo_checkbox{:type=>"checkbox", :name=>"todo[#{todo.id}]"}
      end
      | Complete
```
* `app/views/todos/show.html.slim`
```html
px-3
  h1 = link_to "(#{@todo.title})", todo_path(@todo)
  %p= link_to "Show in Details", show_todo_path(@todo)
  %a.button{"Edit", method: "get", href: edit_todo_path(@todo)}
  %a.button{"New List", href: to_do_path, remote: true}
  %hr
  %p= span.label Todo Title: #{@todo.title}
  %p= span.label Completed: #{@todo.completed?}

  - if current_user
    = link_to "Complete", update_todo_path(@todo), method: "post", remote: true
    = link_to "Edit Completion Status", edit_todo_path(@todo), method: "post", remote: true
    = link_to "Delete", todo_path(@todo), method: "delete", data: { confirm: 'Are you sure?' }

  = form_tag destroy_todo_path(@todo), method: "delete", data: { confirm: 'Are you sure?' } do %>
    <input type="submit" value="Delete" class="button" />
  %input#todo_checkbox{:name=>"todo[#{@todo.id}]", :type=>"checkbox"}

  %div{:style=>"display:none"}= check_completion(@todo)
```
* `app/controllers/todos_controller.rb`
```ruby
class TodosController < ApplicationController
  def index
    @todos = current_user.assigned_todos
  end
  
  def show
    @todo = Todo.find(params[:id])
  end
end
```
Step 4: Add authentication to the app
Create a `User` model with the following migration:
```sh
rails generate model User name:string email:string password_digest:string
```
Then run the following command to create a database for the user:
```sh
rails db:migrate
```

To create a simple ToDo app in Rails 7 with PostgreSQL as the database, you can follow these steps:

1. Install Rails, PostgreSQL, and your operating system's gem package manager (like brew or yum).
2. Create a new Rails 7 application.
3. Set up PostgreSQL as the database for the application.
4. Create a `Tasks` model with checkboxes for completed tasks.
5. Add routes and controllers for the `Tasks` model.
6. Create a view to display a list of tasks.
7. Add JavaScript functionality for completing tasks.

Here are the detailed steps:

1. Install Rails:
Go to the Rails website (<https://rubyonrails.org/downloads>) and download the latest version of Rails. Run the installer and follow the prompts.
2. Install PostgreSQL:
Install PostgreSQL for your operating system. You can find instructions for installing PostgreSQL on their official website (<https://www.postgresql.org/download/>).
3. Add PostgreSQL to your Rails application:
Open the Terminal and run `rails new todo_app --database=postgresql` to create a new Rails application with PostgreSQL.
4. You'll need to create a connection to the PostgreSQL database in your Rails environment. Open the `environments.rb` file in the `config` folder and add `ENV['DATABASE'] = 'postgresql'`.
5. Create the `Tasks` model with checkboxes for completed tasks:
In the `db/schema.rb` file, add `create_table "tasks", force: :cascade do |t|`
```ruby
t.string "title"
t.string "description"
t.boolean "completed"
t.datetime "completed_at"
end`
```
Then execute `rake db:migrate` to create the `tasks` table.
6. Add the `Task` model to your Rails application:
Create the `model` folder and `tasks_controller.rb` file if they don't already exist. In the `tasks_controller.rb` file, add the following code:
```ruby
class TasksController < ApplicationController
  def index
    @tasks = Task.order(:title)
  end
  
  def show
    @task = Task.find(params[:id])
  end
  
  def update
    @task = Task.find(params[:id])
    if @task.update(task_params)
      redirect_to @task, notice: "Task was successfully updated."
    else
      render :show
    end
  end
  
  private
  
  def task_params
    params.require(:task).permit(:title, :description, :completed)
  end
end
```
7. Create the view to display a list of tasks:
In the `views` folder, create a new `tasks.html.erb` file. Replace the content with the following code:
```html
<h1>Your tasks:</h1>
<% @tasks.each do |task| %>
  <%= check_box_tag "task_#{task.id}", task.completed? ? 'checked' : '' %>
  <label>
    <%= task.title %>
    <%= check_box_tag "task_#{task.id}", '' %>
    <%= task.description %>
  </label>
  <%= link_to 'Edit', edit_task_path(task) %>
<% end %>
<%= link_to 'New Task', new_task_path %>
```
8. Add JavaScript functionality for completing tasks:
Update the `app.js` file in the `public/javascripts` folder to include the following code:
```javascript
//= require jquery
//= require rails-ujs
//= require bootstrap
//= require_tree .

$(document).ready(function() {
  $('.checkbox-container input[type="checkbox"]').prop('checked', true);
  
  $(document).on('click', '.edit-task', function() {
    var task_id = $(this).attr('href').split('/')[3];
    $('.checkbox-container input[type="checkbox"]').prop('checked', false);
    $('.checkbox-container input[type="checkbox"][name="task_' + task_id + '"]').prop('checked', true);
  });
  
  $(document).on('click', '.checkbox-container input[type="checkbox"]', function() {
    var task_id = $(
