Writing Middleware

This assignment will build off the authentication demo we do in class, so you will want to use that code base.

Create a configurations Table

In your database, create a table named configurations with columns for id (primary key), name (string), and value (string). Create this table with a migration.

Insert a records into this table name set to “maintenance” and value set to “off”.

The Home Page

Modify the / route so that it redirects to some existing route.

Maintenance Mode Middleware

You are going to create middleware that redirects users to a maintenance mode page at the path /maintenance if there is a record in the configurations table with a name of “maintenance” and its value is “on”. If that record’s value is “off”, users should not be redirected to that page. Name the middleware MaintenanceMode. This middleware should only apply to public routes (the ones without the protected middleware), but exclude the following so that certain users can login even if the site is in maintenance mode.

Route::get('/login', 'LoginController@index');
Route::post('/login', 'LoginController@login');
Route::get('/logout', 'LoginController@logout');

Toggling Maintenance Mode

Create a /settings page that is protected by authentication. This page will have a form with one checkbox that will toggle the configurations record with a name of maintenance.
