Laravel Eloquent: Ordering results of all()

I'm stuck on a simple task. I just need to order results coming from this call

$results = Project::all();

Where Project is a model. I've tried this

$results = Project::all()->orderBy("name");

But it didn't work. Which is the better way to obtain all data from a table and get them ordered?

You can actually do this within the query.

$results = Project::orderBy('name')->get();

This will return all results with the proper order.

You could still use sortBy (at the collection level) instead of orderBy (at the query level) if you still want to use all() since it returns a collection of objects.

Ascending Order

$results = Project::all()->sortBy("name");

Descending Order

$results = Project::all()->sortByDesc("name");

Check out the documentation about Collections for more details.

https://laravel.com/docs/5.1/collections

In addition, just to buttress the former answers, it could be sorted as well either in descending desc or ascending asc orders by adding either as the second parameter.

$results = Project::orderBy('created_at', 'desc')->get();

    

DO THIS:

$results = Project::orderBy('name')->get();

Why? Because it's fast! The ordering is done in the database.

DON'T DO THIS:

$results = Project::all()->sortBy('name');

Why? Because it's slow. First, the the rows are loaded from the database, then loaded into Laravel's Collection class, and finally, ordered in memory.

Laravel 5.4 added orderByDesc() methods to query builder:

$results = Project::orderByDesc('name')->get();

While you need result for date as desc

$results = Project::latest('created_at')->get();

In Laravel Eloquent you have to create like the query below it will get all the data from the DB, your query is not correct:

$results = Project::all()->orderBy("name");

You have to use it in this way:

$results = Project::orderBy('name')->get();

By default, your data is in ascending order, but you can use it in the following way:

$results = Project::orderBy('name', 'asc')->get();

Or in descending order:

$results = Project::orderBy('name', 'desc')->get();

Check out the sortBy method for Eloquent: http://laravel.com/docs/eloquent

Note, you can do:

$results = Project::select('name')->orderBy('name')->get();

This generate a query like:

"SELECT name FROM proyect ORDER BY 'name' ASC"

In some apps when the DB is not optimized and the query is more complex, and you need prevent generate a ORDER BY in the finish SQL, you can do:

$result = Project::select('name')->get();
$result = $result->sortBy('name');
$result = $result->values()->all();

Now is php who order the result.

You instruction require call to get, because is it bring the records and orderBy the catalog

$results = Project::orderBy('name')
           ->get();

Example:

$results = Result::where ('id', '>=', '20')
->orderBy('id', 'desc')
->get();

In the example the data is filtered by "where" and bring records greater than 20 and orderBy catalog by order from high to low.

One interesting thing is multiple order by:

according to laravel docs:

DB::table('users')
   ->orderBy('priority', 'desc')
   ->orderBy('email', 'asc')
   ->get();

this means laravel will sort result based on priority attribute. when it's done, it will order result with same priority based on email internally.

EDIT:

As @HedayatullahSarwary said, it's recommended to prefer Eloquent over QueryBuilder. off course i didn't encourage using QueryBuilder and we all know that each has own usecases.

Any way so why i wrote an answer with QueryBuilder? As we see in eloquent documents:

> You can think of each Eloquent model as a powerful query builder allowing you to fluently query the database table associated with the model.

BTWS the above code with eloquent should be something like this:

Project::orderBy('priority', 'desc')
->orderBy('email', 'asc')
->get();

Try this:

$categories     =   Category::all()->sortByDesc("created_at");
