Laravel 4 Eloquent Cheat Sheet.

eloquent.md

Conventions:

Defining Eloquent model (will assume that DB table named is set as plural of class name and primary key named "id"):

class Shop extends Eloquent {}

Using custom table name

protected $table = 'my_shops';

Using custom primary key (instead of "id"):

protected $primaryKey = 'my_key';

Disabling use of "created_at" and "updated_at" columns:

public $timestamps = false;

Retrieving records:

Retrieving all records(rows) of a given model:

$shops = Shop::all();

Find and get a record by primary key:

$shop = Shop::find(1);

Retrieving single record that matches a certain column : $shop = Shop::where('name', 'Starbucks')->first();

Retrieving specific columns of the result (by default get() returns all columns): $shops = Shop::where('name', 'Starbucks')->get('name','address','url');

Retrieving single column of result : $shopAddresses = Shop::where('name', 'Starbucks')->pluck('address');

Retrieving records matching a criteria:

$profitableShops = Shop::where('orders_cache','>','100')->get(); where() takes 3 parameters, name of the column, operator and value to be compared against. The operator can be one of the following: '=', '<', '>', '<=', '>=', '<>', '!=', 'like', 'not like', 'between', 'ilike'

Retrieve only a specified number of records matching a criteria:

$californianShops = Shop::where('state', 'CA')->take(10)->get();

Skip a specified number of records:

$someShops = Shops::where('name', 'Starbucks')->skip(10)->get();

Combining "skip" and "take" (useful for making custom paginators):

$shops = Shops::where('name', 'Starbucks')->skip(25)->take(25)->get();

Using forPage() to accomplish the above statement:

$shops = Shops::where('name', 'Starbucks')->forPage(2,25)->get();

Aggregates

Counting the number of rows of the query results:

$countStarbucks = Shop::where('name','Starbucks')->count();

Getting a maximum value of the query result:

$maxCoffeePrice = Product::where('name','Coffee')->max('price');

Getting a minimum value of the query result:

$minCoffeePrice = Product::where('name','Coffee')->min('price');

Getting an average value of the query result:

$averageCoffeePrice = Product::where('name','Coffee')->avg('price');

Getting a sum of the query result:

$totalWeight = Product::where('name','Coffee')->sum('weight');

Incrementing and decrementing values of a column:

Shop::where('orders_cache','>','100')->increment('orders_cache');

Shop::where('orders_cache','>','100')->decrement('orders_cache');

Todo :

• or, between, whereNull, whereIn
• inserts
• updates
• deletes
• soft deletes
• unions
• raw expressions
• grouping
• joins
• Fillable
• Guarded

One correction:
$shops = Shop::where('name', 'Starbucks')->get('name','address','url');

should be

$shops = Shop::where('name', 'Starbucks')->get( array('name','address','url') );

get() takes an array as a parameter

Its a Laravel3 thing :-)

This is great. Thanks for posting!

I'm curious how you would do the following statement:

select * from foo where bar in (1,3,10);

Currently I'm doing this:

Foo::where('bar',1)
    ->orWhere('bar',3)
    ->orWhere('bar',10);

But what I hope is that there is something like this:

Foo::where('bar','in',array(1,3,10));

@tacticalcom, try:
Foo::whereIn('bar', array(1,3,10));

Thank you Saved me a great deal of time

This is great post.
most of functionality covered in this post of Laravel
Thanks!

how to count a distinct will be?

how about getting all columns of a table?

SELECT foo, bar from mytable;
MyModel::all() returns all the rows with all columns but I need only few columns. I do not want to specify $hidden in model.
I think ->get(array('foo', 'bar')) will work on Illuminate\Database\Eloquent\Builder and for that I need to use MyModel::where()
According to documentation, where() and get() both are part of builder.
So how to get selected columns for all records without calling where()?

Model::get(['field1','field2']);

Please add some example about complex queries or multi conditions queries. I couldn't find any good example over internet :(

please add information about relationship in eloquent the docs is not clear

You wrote that by default get() returns all columns:

$shops = Shop::where('name', 'Starbucks')->get('name','address','url');

But nothing about how to do for get only one row (maybe it is not best solution):

$shop = Shop::where('name', 'Starbucks')->select(array('name','address','url'))->first();

how do you pass distinct values from database to select boxes?
