i have three table as follows:
users:
id, fullname, phone ...
tasks:
id, user_id, title, description ...
tasks_state:
id, task_id, comment, rating, createa_at, updated_at
i am trying to use Relationships in laravel for order by updated_at in table tasks_state
Model tasks
public function taskstate()
{
return $this->hasOne(TaskState::class, 'task_id');
}
Model tasks_state
public function task()
{
return $this->belongsTo(Tasks::class, 'id', 'taks_id');
}
I want the data returned sorted by field updated_at in table tasks_state when i use:
Tasks:with('taskstate')->get();
Look forward to your help :(
Change your Task Model like this:
Model tasks
public function taskstate()
{
return $this->hasOne(TaskState::class, 'task_id')->orderBy('tasks_state.updated_at');
}
You can use query builder within with clause and order the task state by updated_at
Tasks:with([
'taskstate' => function($query){
$query->orderBy('updated_at', 'desc');}
])->get();
If you want to retrieve everytime with updated_at in desc order, you can reference to Stack Overflow: Laravel default orderBy

I have the following tables. users, user_details and client_teams. Each user has one details and each user can have many teams. schema for users:
id, name, email,parent_user_id
user_details:
id, user_id, client_team_id
client_teams:
id, user_id, team_name,status
In user_model i have the following relations:
public function userDetails(){
return $this->belongsTo('App\Models\UserDetails','id','user_id');
}
public function clientTeamList(){
return $this->hasMany('App\Models\ClientTeams','user_id','id');
}
In user_details model i have the following relation:
public function clientMemberTeam(){
return $this->belongsTo('App\Models\ClientTeams','client_team_id');
}
I want to be show the list of users who have a specific team ID and created by a specific user. The query that i am using is this:
$userCollections=Users::where([
['users.status','!=','DELETE'],
['users.parent_user_id',$clientId],
['users.id','!=',$loginUser->id]
])
->with([
'userDetails'=>function($query) {
$query->where('client_team_id',1);
}
]);
This is giving me all records for this user, Whereas i want to match by client_team_id and user_id
You need to use whereHas and orWhereHas methods to put "where" conditions on your has queries.
Please look into https://laravel.com/docs/8.x/eloquent-relationships
$userCollections = Users::where([['users.status', '!=', 'DELETE'],
['users.parent_user_id', $clientId],['users.id', '!=', $loginUser->id]
])
->whereHas('userDetails' => function ($query) {
$query->where('client_team_id', 1);
})->get();
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.
How can I retrieve all records of my model based on certain ID's in my pivot table?
I have the following 3 tables
users;
id,
name
stats;
id,
name
stats_selected;
user_id,
stats_id
Model
User.php
public function stats()
{
return $this->belongsToMany('App\stats', 'stats_selected', 'user_id', 'stats_id')->withTimestamps();
}
Controller
// Get all users with example of stats ID's
$aFilterWithStatsIDs = [1,10,13];
$oUser = User::with(['stats' => function ($query) use($aFilterWithStatsIDs ) {
$query->whereIn('stats_id', $aFilterWithStatsIDs);
}])
->orderBy('name', 'desc')
->get()
This outputs just all the users. Btw, fetching users with there stats and saving those selected stats into the DB is not a problem. That works fine with the above lines.
But how do I retrieve only the users which has certain stats_id's within them?
But how do I retrieve only the users which has certain stats_id's within them?
Use a whereHas conditional.
User::whereHas('stats', function ($stats) use ($aFilterWithStatsIDs) {
$stats->whereIn('id', $aFilterWithStatsIDs);
});
assuming that I have the table
orders
with fields
id, userId, amount, description
and the table
user
with various fields
how if I wand to get all the users (with all its fields) and also the sum of the "amount" column of the orders related to that user?
assuming that I have:
user:{id:15,firstName:jim,lastName:morrison,gender:male}
and
order:{id:1,userId:15,amount:10,description:"order xxx"},
order:{id:3,userId:15,amount:40,description:"order yyy"}
I would like to receive:
user:{id:15,firstName:jim,lastName:morrison,gender:male,orderAmount:50}
Of course I would like to avoid the foreach statement.
I've setted this on my user model
public function userOrder (){
return $this->hasMany('Order', 'userId');
}
And I've tryed this:
return $this->hasMany('Order', 'userId')->sum('amount');
without any luck...
Some thaughts and hopefully an answer to your question:
I would rename the user table to users to stick to laravel conventions.
http://laravel.com/docs/4.2/eloquent#basic-usage
I would name the method in the User model orders
public function orders()
{
return $this->hasMany('Order', 'userId');
}
To query a user, his orders and sum afterwards his orders amount values:
$userdata = User::with( 'orders' )->where( 'userId', 15 )->first();
$sum = $userdata[ 'orders' ]->sum( 'amount' );
I have 4 tables that I'm trying to work with in Laravel and I can't figure out how to use eloquent to execute a particular query. I want to update all orders that belong to a user (through product_id) and that have null payout_id.
This raw sql statement works but I'm not sure how to use eloquent for this..perhaps sync?
UPDATE order_items i JOIN products p on (i.product_id = p.id) SET i.payout_id = null where p.user_id = 3
User Model
Product Model
FK: user_id
Order Model
FK: product_id
FK: payout_id
Payout Model
I would really appreciate any help!
First define a function orders in User Model
public function orders()
{
return $this->hasManyThrough('Orders', 'Product','user_id','product_id');
}
User::where('id','=',$userid)->with(array('orders'=>function($query){
$query->where('payout_id','=',0)->update(array('payout_id'=>$updatevalue));
}))->first();
You need to create a model for your tables i and p, see http://laravel.com/docs/eloquent for full information on model creation.
In the model for i you would then create a relationship to p:
public function p()
{
return $this->('p','id','product_id');
}
You can then run your query as follows:
$results = i::with('p')
->where('user_id', '=', 3)
->update(array('payout_id' => null));
