public function run()
{
factory(App\ProjectProcurementManagementPlan::class, 5)->create()->each(function ($a) {
$a->paps()
->saveMany( factory(App\ProjectsProgramsActivities::class, 5)->make() )
->each(function ($b) {
$b->pap_schedules()->save(factory(App\PapSchedule::class)->make());
$b->procurement_modes()-> ????????;
});
});
}
I have this code here. I want to seed a pivot table after creation of each of the models indicated above. $b->procurement_modes()-> ???????? will be the part where I do the factory stuff to a pivot table.
the pivot table looks like this.
| id | pap_id | procurement_mode_id |
My plan is, to , for the sake of simplicity, I'll just attach a single procurement_mode_id to each ProjectsProgramsActivities created.
I have tried to use
$b->procurement_modes()->sync(factory(App\PAPProcurementMode::class)->make());
but it gives me a
SQLSTATE[HY000]: General error: 1366 In
correct integer value: '' for column 'procurement_mode_id' at row 1 (SQL: insert
into paps_procurement_modes (pap_i, procurement_mode_id) values (1, ))
The factory for that pivot table is this
$factory->define(App\PAPProcurementMode::class, function (Faker $faker) {
return [
'procurement_mode_id' => 1,
];
});
So what would be the best way to do this ?
For those who will encounter problems like this.
I simply
$ids = 1;
$b->procurement_modes()->sync($ids);

I have found this: Get Specific Columns Using “With()” Function in Laravel Eloquent
but nothing from there did not help.
I have users table, columns: id , name , supplier_id. Table suppliers with columns: id, name.
When I call relation from Model or use eager constraints, relation is empty. When I comment(remove) constraint select(['id']) - results are present, but with all users fields.
$query = Supplier::with(['test_staff_id_only' => function ($query) {
//$query->where('id',8); // works only for testing https://laravel.com/docs/6.x/eloquent-relationships#constraining-eager-loads
// option 1
$query->select(['id']); // not working , no results in // "test_staff_id_only": []
// option 2
//$query->raw('select id from users'); // results with all fields from users table
}])->first();
return $query;
In Supplier model:
public function test_staff_id_only(){
return $this->hasMany(User::class,'supplier_id','id')
//option 3 - if enabled, no results in this relation
->select(['id']);// also tried: ->selectRaw('users.id as uid from users') and ->select('users.id')
}
How can I select only id from users?
in you relation remove select(['id'])
public function test_staff_id_only(){
return $this->hasMany(User::class,'supplier_id','id');
}
now in your code:
$query = Supplier::with(['test_staff_id_only:id,supplier_id'])->first();
There's a pretty simple answer actually. Define your relationship as:
public function users(){
return $this->hasMany(User::class, 'supplier_id', 'id');
}
Now, if you call Supplier::with('users')->get(), you'll get a list of all suppliers with their users, which is close, but a bit bloated. To limit the columns returned in the relationship, use the : modifier:
$suppliersWithUserIds = Supplier::with('users:id')->get();
Now, you will have a list of Supplier models, and each $supplier->users value will only contain the ID.
I have 2 database tables in MySQL below.
Table - 1
CREATE TABLE `tblaccount` (
`account_id` mediumint(8) UNSIGNED NOT NULL,
`account_number` varchar(100)
)
ALTER TABLE `tblaccount`
ADD PRIMARY KEY (`account_id`);
Table - 2
CREATE TABLE `tblcollectoractions` (
`collector_action_id` mediumint(8) UNSIGNED NOT NULL,
`account_id` mediumint(8) UNSIGNED DEFAULT NULL,
`pay_date` date DEFAULT NULL
);
ALTER TABLE `tblcollectoractions`
ADD PRIMARY KEY (`collector_action_id`),
ADD KEY `tblcollectoractions_account_id_foreign` (`account_id`);
I have a query below. It joins records in both tables on the basis of account_id. It also filters those accounts in tblcollectoractions table where pay_date lies between start and end date.
Here is my Laravel Eloquent Query. AccountModel is related to tblaccount and ActionModel is related to tblcollectoractions.
$query = (new AccountModel())->newQuery();
$data->whereIn("account_id", function($query) use($inputs) {
$query->select('account_id')->from(with(new ActionModel)->getTable())
->whereBetween('pay_date', [$inputs["from_pay_date"], $inputs["to_pay_date"]]);
});
But, this shows me all the records from table tblcollectoractions. I meant, it does not filter on the basis of start and end date.
Am I missing anything?
This is the most Eloquent way to do this, checking if the $inputs variable is set
$data = AccountModel::query()
->with([
'actions' => function($query) use ($inputs) {
if ($inputs['from_pay_date']) {
$query->whereBetween('pay_date', [
$inputs['from_pay_date'],
$inputs['to_pay_date']
]);
}
}
])
->has('actions')
->get();
the models should look something like this:
AccountModel.php
class AccountModel extends Model
{
protected $guarded = ['id'];
public function actions()
{
return $this->hasMany(ActionModel::class, 'account_id', 'account_id');
}
}
I have Games table and which has the following schema
id | status | name
status column has 2 values (Active, Pending)
And GamePlayer table which has the following schema
id | game_id | player_id | request_status
request_status column has 3 values (Pending, Confirm, Rejected)
Now I have to select all game in which the player is involved but with the following constraints:
If the game is Pending state then it will be shown to all game_players
If the game is in Active state then it will be only shown to the game_player whose request_status is Confirm.
Game(Model)
public function GamePlayer()
{
return $this->hasMany('App\Models\GamePlayer', 'game_id', 'id');
}
public function getGames($playerId)
{
$gameList = Game::with(['GamePlayer','Category:id,name'])
->whereHas('GamePlayer', function ($q) use ($playerId) {
$q->where('player_id', $playerId);
})->get();
return $gameList;
}
Controller
$this->gameObj = new Game();
$gameList = $this->gameObj->getGames($player_id);
Please help me out how can I populate data from another table based on condition(parent table as well as the child).
You can use condition in your relationship to get only confirmed game players
public function activeGamePlayers()
{
return $this->hasMany('App\Models\GamePlayer', 'game_id', 'id')
->where('request_status', 'confirm');
}
You can as well use scopes (https://laravel.com/docs/7.x/eloquent#local-scopes) to select only active games
public function scopeActive($query)
{
return $query->where('status', 'active');
// You can then use $game->active()->...
}
So your getGame would look like:
public function getGames($playerId)
{
$player = GamePlayer::find($playerId);
if ($player->status == 'active') {
$gameList = Game::with(['GamePlayer', 'Category:id,name'])
->get();
} else {
$gameList = Game::with(['GamePlayer', 'Category:id,name'])
->active()->get();
}
return $gameList;
}
NOTE:
in your specific case, I would instead get started from the GamePlayer Model to get the games, instead of coming from the Game Model - you can use scopes and conditions in relationships as well to make your code more readable.
You can use Laravel method whereHas. You should read this part of Laravel the documentation.
Note that you should have relationships declared on every model.
for example table1 and table2 and connected together by a pivot table
table1: {
pivot: {
pivot_value1: 1
},
table2: {
....
}
}
code:
table1::with(['table2' => function($q) {
$q->where('table2_property1', 'pivot_value1') // <= how to access pivot value?
}])
In your model where you are defining relationship , we need to use withPivot() function while making relationship e.g in your table1 Model we have;
class Table1 {
public function table2() {
return $this->belongsToMany('App\Table2')->withPivot('column1', 'column2');
}
}
Normally in pivot table there are three cloumns, in addition if we have added extra columns let's say column1 & column2, we can get the values of these extra cloumns. Here column1 & column2 are the extras columns in your pivot tables,
To access these columns values:
$table1 = Table1::find(1);
foreach ($table1->table2 as $table) {
echo $table->pivot->column1;
echo $table->pivot->column2;
}
Another Solution using query builder:
Table1::whereHas('table2', function($q) {
$q->where('table2_property1', 'pivot_value1');
})
->get();
The above code is just an example, you can do modify it that perfect your needs. Hope it helps.
I try to update field rate in table by primary key user_id.
So, I need to increment of decrement rate field. If row is not exist I need to create it.
I tried:
$this->point = -1; // Or $this->point = 1;
Rating::updateOrCreate(["user_id", $id], ["rate" => $this->point]);
But it does not work:
SQLSTATE[42S22]: Column not found: 1054 Unknown column '0' in 'where clause' (SQL: select * from `rating` where (`0` = user_id and `1` = 5) limit 1)
This is because your passing the column and the value as two separate values.
Change:
["user_id", $id]
to:
["user_id" => $id]
Hope this helps!
Laravel (eloquent) provides a fluent way to update related models.
Assuming the following model structure:
Rating.php
public function user()
{
return $this->belongsTo('App\User');
}
User.php
public function ratings()
{
return $this->hasMany('App\Rating');
}
You can easily update the relation via associate()
$user = User::findOrFail($userId);
$rating = Rating::findOrFail($ratingId);
$rating->user()->associate($user)->save();
