I need to make a list of scopes from my positions->areas->scopes on my Booking Model.
My tables look like that:
Booking
id
...
Position
id
booking_id
...
Area
id
..
Position_areas
id
area_id
position_id
Scope
id
...
Area_Scopes
id
area_id
scope_id
And this are my relations:
class Booking extends Model
{
...
public function positions()
{
return $this->hasMany(BookingPosition::class);
}
public function areas()
{
return $this->hasManyThrough(Area::class, PositionsAreas::class, 'area_id', 'id', 'position_id', 'area_id');
}
...
}
class BookingPosition extends Model
{
...
public function booking()
{
return $this->belongsTo(Booking::class);
}
public function areas()
{
return $this->belongsToMany(Area::class, 'position_areas', 'position_id', 'area_id')
->using(PositionsAreas::class);
}
...
}
class PositionsAreas extends Pivot
{
...
protected $table = 'position_areas';
public function positions(){
return $this->belongsTo(BookingPosition::class);
}
public function areas(){
return $this->belongsTo(Area::class);
}
...
}
class Area extends Model
{
...
public function bookingPositions()
{
return $this->belongsToMany(
BookingPosition::class
)->using(PositionsAreas::class);
}
public function scopes()
{
return $this->belongsToMany(Scope::class, table: 'scope_areas');
}
...
}
class Scope extends Model
{
...
public function areas(){
return $this->belongsToMany(Area::class, table: 'scope_areas');
}
...
}
And I want to have a list of all areas on my booking model, but I don't know how to achieve that.
So that I can do something like that
...
$booking->load('scopes');
[
id
date
...
scopes => [
{...},
{...}
]
]
I tried to create pivot models for position_areas but i cant even get a list of areas on my booking model.
I couldn't figure out how to solve this with a relation like hasManyThrough but as workaround I make all scopes available in my $bookings like that.
$booking = Booking::find($booking->id);
$booking->scopes = $booking->positions
->pluck('areas')
->flatten()
->pluck('scopes')
->flatten()
->pluck('name')
->unique()
->values()
->all();

Been having a hard time on figuring out how to implement updating records on a nested createMany based on the store method. I have these models and relations:
User Model:
class User extends Model
{
public function orders() {
return $this->hasMany(Order::class);
}
}
Order Model:
class Order extends Model
{
public function user() {
return $this->belongsTo(User::class);
}
public function subOrders() {
return $this->hasMany(SubOrder::class);
}
}
SubOrder Model:
class SubOrder extends Model
{
public function order() {
return $this->belongsTo(Order::class);
}
public function subOrderProducts() {
return $this->hasMany(SubOrderProducts::class);
}
}
SubOrderProducts Model:
class SubOrderProducts extends Model
{
public function subOrder() {
return $this->belongsTo(SubOrder::class);
}
}
Here are the tables:
orders table:
id name
sub_orders table:
id order_id date price
sub_order_products table:
id sub_orders_id product_id
Then on the store method:
public function store(StoreOrderRequest $request) {
$order = auth()->user()->orders()->create($request->validated());
$order_subs = $order->subOrders()->createMany($request->orders);
$order_sub_products = $request->only('subproducts');
foreach ($order_subs as $key => $value) {
$order_sub->subOrderProducts()->createMany($order_sub_products[$key]['products']);
}
}
What I wanted to achieve is to update or create those sub orders and sub order products. If the sub order is already existing, then update, otherwise create a new record with those corresponding sub order products.
Here's what I've tried so far:
public function store(UpdateOrderRequest $request, Order $order) {
$order->update($request->validated());
$order_subs = $order->subOrders()->updateMany($request->orders);
$order_sub_products = $request->only('subproducts');
foreach ($order_subs as $key => $value) {
$order_sub->subOrderProducts()->updateMany($order_sub_products[$key]['products']);
}
}
It's not working as expected since the order subs is only a single record. What's the best way or the right process for updating/creating these records? Thanks.
I have order and return tables which have a created_by and accepted_by field where the corresponding user id is stored.
But now I would like to have multiple types for created_by and accepted_by instead of only user type. Assume a company could also create or accept the order/return.
I was thinking of a polymorphic one to many relationship.
Let’s name this table participants.
Something like:
ID
created
participantable_id
participantable_type
1
1
1
user
2
0
11
company
This works either for order or return but not both.
Is it practically to add extra colums to participants like trx_id and trx_type (order/return)?
How would the realtionships looks like to perform queries like:
$order->createdBy // should give me either user or company model
$order->acceptedBy
$return->createdBy
$return->acceptedBy
Or is there even a cleaner solution I am overlooking?
Thanks!
It would be 1:N polymorphic relationships so no need for an extra table. The structure can be found in the documentation
Your Order and Return model need to have the columns created_by_id, created_by_type, accepted_by_id, accepted_by_type.
______ (1) Company
/
Order (N) ----<
\______ (1) User
_____ (1) Company
/
Return (N) ----<
\_____ (1) User
class Order extends Model
{
public function created_by()
{
return $this->morphTo(__FUNCTION__, 'created_by_type', 'created_by_id');
}
public function accepted_by()
{
return $this->morphTo(__FUNCTION__, 'accepted_by_type', 'accepted_by_id');
}
}
class Return extends Model
{
public function created_by()
{
return $this->morphTo(__FUNCTION__, 'created_by_type', 'created_by_id');
}
public function accepted_by()
{
return $this->morphTo(__FUNCTION__, 'accepted_by_type', 'accepted_by_id');
}
}
class User extends Authenticatable
{
public function created_orders()
{
return $this->morphMany(Order::class, 'created_by');
}
public function accepted_orders()
{
return $this->morphMany(Order::class, 'accepted_by');
}
public function created_returns()
{
return $this->morphMany(Return::class, 'created_by');
}
public function accepted_returns()
{
return $this->morphMany(Return::class, 'accepted_by');
}
}
class Company extends Model
{
public function created_orders()
{
return $this->morphMany(Order::class, 'created_by');
}
public function accepted_orders()
{
return $this->morphMany(Order::class, 'accepted_by');
}
public function created_returns()
{
return $this->morphMany(Return::class, 'created_by');
}
public function accepted_returns()
{
return $this->morphMany(Return::class, 'accepted_by');
}
}
I am new to laravel and trying the following:
I have these tables:
disciplines: id | name
specialties: id | name
categories: id | name
discipline_specialty (pivot table): id | discipline_id | specialties_id
Discipline model:
public function specialties()
{
return $this->belongsToMany(Specialty::class);
}
Specialty model:
public function disciplines()
{
return $this->belongsToMany(Discipline::class);
}
My question is:
how can I relate (many to many) the categories to the pivot table discipline_specialty in order to access the category name with the discipline and specialty ids?
I had thought of an additional pivot table that linked category id and discipline_specialty id but I don't know if it's the best solution and how to do it. Do you have any suggestions? Any help is appreciated.
You can introduce a junction/pivot model that will relate these 3 relations as many-to-one/belongsTo and one-to-many/hasMany from Discipline/Speciality/Category.
Discipline Speciality Category
\\ || //
\\ || //
DisciplineSpecialityCategory
This DisciplineSpecialityCategory model will have following attributes or FKs
Table: discipline_speciality_category
discipline_id
speciality_id
category_id
Now you model definitions will be like
class Discipline extends Model
{
public function disciplineSpecialityCategory()
{
return $this->hasMany(DisciplineSpecialityCategory::class, 'id', 'discipline_id');
}
}
class Speciality extends Model
{
public function disciplineSpecialityCategory()
{
return $this->hasMany(DisciplineSpecialityCategory::class, 'id', 'speciality_id');
}
}
class Category extends Model
{
public function disciplineSpecialityCategory()
{
return $this->hasMany(DisciplineSpecialityCategory::class, 'id', 'category_id');
}
}
class DisciplineSpecialityCategory extends Model
{
public function discipline()
{
return $this->belongsTo(Discipline::class, 'id', 'discipline_id');
}
public function speciality()
{
return $this->belongsTo(Speciality::class, 'id', 'speciality_id');
}
public function category()
{
return $this->belongsTo(Category::class, 'id', 'category_id');
}
}
I have the following models in a many-to-many relationship:
class Event extends Model
{
public function positions() {
return $this->belongsToMany(Position::class, 'position_events');
}
}
class Position extends Model
{
public function events() {
return $this->belongsToMany(Event::class, 'position_events');
}
}
class PositionEvent extends Model
{
public function position() {
return $this->hasOne(Position::class, 'id', 'position_id');
}
public function event() {
return $this->hasOne(Event::class, 'id', 'event_id');
}
}
The position_events table looks like:
id | event_id | position_id
If $event is an instance of Event, I can get the related positions as:
$event->positions;
This gives me something like the following for each related Position:
{"id":4,"name":"Striker","created_at":"2019-04-02 16:19:57","updated_at":"2019-04-02 16:19:57","pivot":{"event_id":27,"position_id":4}}
Notice the pivot element. It only has event_id and position_id as properties, these are columns from the position_events table. How do I get it to have the id column from that table as well?
Have you tried using withPivot(), for example:
$this->belongsToMany(Position::class, 'position_events')->withPivot('id');
I have 4 tables: countries, activities, country_activities and packages.
countries and activities are related through pivot table country_activity, and packages is related to country_activity.
Now, How do I eager load all packages related to each activity in a country?
class Country extends Model
{
public function activities() {
return $this->belongsToMany('App\Models\Activity','country_activities')->using('App\Models\CountryActivity')->as('country_activities');
}
}
class Activity extends Model
{
public function countries() {
return $this->belongsToMany('App\Models\Country','country_activities')->using('App\Models\CountryActivity')->as('country_activities');
}
}
class Package extends Model
{
public function country_activities() {
return $this->belongsToMany('App\Models\CountryActivity');
}
}
class CountryActivity extends Pivot
{
protected $table = 'country_activities';
public function packages() {
return $this->hasMany('App\Models\Package');
}
}
So, this worked for me.
class Country extends Model
{
public function activities() {
return $this->belongsToMany('App\Models\Activity','country_activities')->using('App\Models\CountryActivity')->withPivot(['id'])->as('country_activities');
}
Now, In my controller, I do this
$country = Country::with(['activities'=> function($q) {$q->where('name','Trekking');}])->where('name','Nepal')->first(['id','name']);
$country->activities->map(function ($i){
$i->country_activities->load('packages');
return $i;
});
I did something similar in a project i worked on. I'm not sure it will work but it's worth the shot:
$country = Country::find(1);
$country->activities = $contry->activities()->get()->each(function ($i, $k){
$i->packages = $i->pivot->packages;
//$i->makeHidden('pivot'); -> This is useful if you want to hide the pivot table
});
var_dump($country);
