Database

Migrations files are provided with such tables:

  1. pricelists. This table is like a container for pricelist items. It has such fields:

    • order - sets priority on a frontend
    • active - defines if the pricelist is active or not

    Translatable fields of the table 'pricelists' are in the table 'pricelist_translations'. Table 'pricelists' has many pricelist translations

  2. pricelist_translations. Fields:

    • pricelist_id - id of the related pricelist
    • locale - language of translation
    • title - title of the pricelist
    • description - description of the pricelist if needed

  1. pricelist_items. Elements of pricelists. Fields:

    • shortcut - for internal usage to identify your pricelist item. For example, if you have different items with the same title
    • price - price of your product. In case the 'max_price' field is set, this one stands for minimum price.
    • max_price - if your product has no fixed price this field describes maximum price.
    • price_from - if the price of your product starts from the value set in 'price' field and has no upper bound. Boolean.
    • active - defines if the pricelist item is active or not

    Translatable fields of the table 'pricelist_items' are in the table 'pricelist_items_translations'. Table 'pricelists' has many pricelist translations

  2. pricelist_items_translations. Fields:

    • pricelist_item_id - id of the related pricelist item
    • locale - language of translation
    • title - name of your product
    • units - in what units your product can be calculated

  1. pricelist_pricelist_item. Pivot table for pricelists and pricelist_items in many to many relationship. Also contains field 'item_order', which defines order of an element within the table.

  2. pricelistables. Polymorphic many to many relationship table. Responsible for attaching a pricelist to your pricelistable models.

Usage

Registering Models

To let your models be able to attach pricelists, add the HasPricelist trait to your model class

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Nestermaks\LaravelPricelist\HasPricelist;

class Offer extends Model
{
    use HasPricelist;
    ...
}

Associating pricelists

You can associate a pricelist with a model like this:

$offer = Offer::first();
$pricelist = Pricelist::first();

$offer->addPricelist($pricelist);

Or you can detach pricelist from a model:

$offer->removePricelist($pricelist);

To watch all pricelists of the model:

$offer->pricelists();

Show pricelists and pricelist items

To show all active pricelists:

Pricelist::getActiveItems();

The same for pricelist items

PricelistItem::getActiveItems();

To show pricelist items related to the pricelist:

Pricelist::relatedItems();

To show pricelists where the pricelist item is present:

PricelistItem::relatedItems();

Attach and detach pricelist items to pricelist

Assuming we have such variables:

$pricelists = Pricelist::all();
$pricelist = Pricelist::first();
$pricelist_items = PricelistItem::all();
$pricelist_item = PricelistItem::first();

To attach items to the pricelist:

$pricelist->attachItems($pricelist_items);

Or to attach one pricelist item to many pricelists:

$pricelist_item->attachItems($pricelists);

To detach items from the pricelist:

$pricelist->detachItems($pricelist_items);

To detach item from given pricelists:

$pricelist_item->detachItems($pricelists);

Notice that the argument in all these cases is a Collection.

Reordering pricelist items within the pricelist

When you attach pricelist items to the pricelist, each of them gets its order number. To see order number of a pricelist item in the pricelist use:

$pricelist->getItemOrder($pricelist_item);

or

$pricelist_item->getItemOrder($pricelist);

To set a new order number of a pricelist item within the pricelist use:

$pricelist->changeItemOrder($pricelist_item, 3);

or

$pricelist_item->changeItemOrder($pricelist, 3);

Second argument is for new order number. After you assign a new order number of the pricelist item, another ones will rearrange appropriately inside the pricelist.

Api routes

You may use api calls to manage your pricelists. Set desired api prefixes in a config file or leave it default. For pricelists and pricelists items CRUDS are used api resource routes with api resource controllers. You may look through the Laravel DOCS.
