A handy @laravelphp Collection macro to convert an array and its children to Collections, using recursion.

🔥 Use Common Table Expressions to refine your data in complex Eloquent queries

⚡️ Database Tip

Sometimes you have very complex queries involving multiple calculation steps. Instead of nesting queries or doing it in application code you can use Common Table Expressions (CTE) to refine your data in every step and even reuse former steps.

🔥 You can chain ->can() to Route definitions to specify policy rules

#Laravel Tip: If you are running Laravel v8.70, you can chain can() method directly instead of middleware('can:..')

Here is and example:

🔥 Use the --requests flag when creating models to also create form requests

This release of Laravel also includes a "--requests" flag when making models via Artisan. This option will create a "Store{Model}Request" and "Update{Model}Request" form request + update the controller to use those requests on their respective methods. 🔥

Thanks @PovilasKorop!

🔥 You can use factories for generating ANY fake test data by making them use the Fluent model

I really love using Laravel's Eloquent factories for generating fake test data. Did you know that you can also use them to generate fake API response data by using "Fluent" as the model name? Super cool! 🤯

🔥 You can show a link to the previous page by using url()->previous() in a Blade view

💡 Check if there's a previous URL when showing error pages instead of linking to static page!

It's incredibly useful if your marketing and app pages share the same error pages! It makes sure your users won't get lost :)

🔥 Use the Str::headline() method to convert strings to studly words

💡It's refactor time!

Laravel 8.65 introduces the Str::headline() method, this method converts a string into studly words!

A small change like this results in less noise in my code.

Thanks @SteveTheBauman for this implementation! 🙌

🔥 Use the withAggregate() method to add related values to Eloquent queries using subselects

💡 A little #Laravel tip from the latest blog post to get the week started!

Under the hood, the withAvg/withCount/withSum and other methods in Eloquent use the 'withAggregate' method. You can use this method to add a subselect based on a relationship 💫
