Laravel Gates – a graphical intro for beginners

Gates! The first impression it makes is “way to enter somewhere”. But, in reality, the primary responsibility of a gate is to prevent unwanted entry. Another perspective of thinking about gates is – different gates will take you to different places.

Laravel picked this word, “Gate” to name its basic authorization system. What a beautiful similarity between the purpose of an authorization system and the real life gates!

In this post, we are going to:

  • Take a simple application as an example scenario.
  • Identify the usages of authorization in this application.
  • And then, how we can solve it using Laravel Gates.

Using MySQL’s Event Scheduler (No cron job)!

In MySQL, you can use the Event Scheduler to periodically refresh or update table data at specified intervals.

Here’s a step-by-step guide on how to set up a scheduled event to refresh table data every 1 hour:

1. Enable Event Scheduler:

Before you can use the Event Scheduler, make sure it is enabled. You can enable it by setting the event_scheduler system variable.

-- Enable the Event Scheduler
SET GLOBAL event_scheduler = ON;

2. Create a Stored Procedure:

Create a stored procedure that contains the logic to refresh or update the table data. Replace your_table and your_refresh_logic with your actual table name and refresh logic.


    -- Your refresh logic here (e.g., replace this comment with actual SQL statements)
    -- UPDATE your_table SET column1 = value1, column2 = value2, ...;

    -- Commit changes if needed
    -- COMMIT;
END //


3. Create a Scheduled Event:

Create a scheduled event that calls the stored procedure at the desired interval (every 1 hour in this case).

-- Create a scheduled event
    CALL RefreshTableData();

4. Verify the Event:

You can check if the event is created and enabled by querying the events table.

-- Check events

Important Notes:

  • Ensure that the event_scheduler variable is set to ON at the session or global level.
  • Adjust the stored procedure (RefreshTableData()) with the actual SQL statements to refresh your table data.
  • Make sure to test the stored procedure independently before creating the scheduled event.
  • The example assumes that your MySQL user has the necessary privileges to create events.

By following these steps, you can set up a scheduled event in MySQL to refresh a table data every 1 hour. Adjust the table name and refresh logic according to your specific use case.

How to get all indexes of a table in Laravel

You can list all indexes of a table, along with the field names in Laravel. It’s very quick and easy with DB Facade and Laravel Collection.

Here is the code you’ll need. Right, just a single, chained statement! 😉

use Illuminate\Support\Facades\DB;

collect(DB::select("SHOW INDEXES FROM products"))
    ->mapToGroups(fn($row) => [$row->Key_name => $row->Column_name])

The output will be something like the following.

E-Code Verifier relocated

E-Code Verifier is a free web application for checking/verifying Shariah status (Halal, Haram, Mushbooh) of E Code (food ingredient codes). It was developed as a PWA and published in Jun 2016 at ecode.halal-haram.com. By the time of July 2018, it was hitting 12k+ traffic monthly from search engines (without any kind of promotion) and also a good number of usages from desktop/mobile installations.

E-Code Verifier Analytics of mid-2018

A few months ago, the domain “halal-haram.com” got expired! And I have been very busy at that time and didn’t notice! When I realized it, it’s already too late to recover. So, I have relocated it to ecode.figlab.io.

I hope it will become useful again and will save thousands of Muslims from consuming foods with haram ingredients unintentionally.
