}

I need to change the dynamic value in the Articles model depending on the parent language value, so that when the language value is "en", the result is "title" = article_1, article_2
you can try this, in Articles Model
public function articleTitleLang()
{
return $this->hasMany(ArticlesTitleLang::class, 'article_id', 'id')
->where('lang_id', $this->lang_id)->first();
}

This is in relation to this question. I'm having this error:
TypeError
Illuminate\Database\Grammar::parameterize(): Argument #1 ($values) must be of type array, int given, called in /var/www/html/vendor/laravel/framework/src/Illuminate/Database/Query/Grammars/Grammar.php on line 920
While inserting data using createMany. This is the form request data:
{
"name": "My Order",
"orders": [
{
"date": "2022-05-17",
"product_id": [1],
"price": 1
},
{
"start_date": "2022-05-18",
"product_id": [2],
"price": 2
}
]
}
This is the store method:
$order = auth()->user()->orders()->create($request->validated());
$order_subs = $order->subOrders()->createMany($request->orders);
$order_sub_items = $request->only('orders')['orders'];
foreach ($order_subs as $key => $value) {
$value->subOrderProducts()->createMany([$order_sub_items[$key]);
}
However, if the product_id is not an array, it will store properly. Sample form request data:
{
"name": "My Order",
"orders": [
{
"date": "2022-05-17",
"product_id": 1,
"price": 1
},
{
"start_date": "2022-05-18",
"product_id": 2,
"price": 2
}
]
}
How to fix this error?
I want to filter users based on their subscription_status which s stored in a pivot table.
I have Three tables users , subscription_packages , subscription_package_user
$user=User::with(['studentDetails','subscriptionsSatus.courses'])
->withPagination($offset,$perPage)
->get()
->sortBy('first_name')->values();
this code return the response is
[
{
"id": 44,
"first_name": "Abcd Test",
"last_name": "Test lastname",
"student_details": null,
"subscriptions_satus": [
{
"id": 1,
"name": "Gold",
"price": 3000,
"user_id": "2"
"pivot": {
"user_id": 44,
"subscription_package_id": 1,
"subscription_status": "on_free_trial",
"expires_on": null,
"id": 9
},
"courses": [
{
"id": 18,
"title": "English Grammar for Class 3",
"price": 400,
"strikethrough_price": null,
"status": "draft",
"user_id": 2,
"image": "http://127.0.0.1:8000/courses/1615702915.png",
"description": null,
"pivot": {
"subscription_package_id": 1,
"course_id": 18,
}
}
]
}
]
}]
i want to return only users who having subscription_status =$filter.
$filter='acive'or 'on_free_trail'
my model is
public function subscriptionsSatus()
{
return $this->belongsToMany(SubscriptionPackage::class)->withTimestamps()->withPivot('subscription_status','expires_on','id');
}
I havetried
$filter=$request->input('filter')??"active";
$user=User::with(['studentDetails','subscriptionsStatus.courses'])
->whereHas('subscriptionsStatus', function($query) use($filter){
$query->wherePivot('subscription_status','=',$filter);
})
->withPagination($offset,$perPage)
->get()
->sortBy('first_name')->values();
But Got error Column not found 'pivot'
You need to use wherePivot along with the orWhere like below:
public function subscriptionsStatus()
{
return $this->belongsToMany(SubscriptionPackage::class)
->withTimestamps()
->withPivot('subscription_status','expires_on','id')
->wherePivot(function($q){
return $q->where('subscription_status','=','active')
->orWhere('subscription_status','=','on_free_trail');
});
}
Update
Or in your controller:
$user=User::with(['studentDetails','subscriptionsStatus.courses'])
->whereHas('subscriptionsStatus', function($query) use($filter){
$query->withPivot('subscription_status')
->wherePivot('subscription_status','=',$filter);
})
->withPagination($offset,$perPage)
->get()
->sortBy('first_name')->values();
I need help to sort array by couple of logics
[
{
"id": 1,
"status": "pending",
"date": "2019-08-01"
},
{
"id": 2,
"status": "delivered",
"date": "2019-08-01"
},
{
"id": 3,
"status": "pending",
"date": "2019-08-03"
},
{
"id": 4,
"status": "delivered",
"date": "2019-08-03"
},
{
"id": 5,
"status": "delivered",
"date": "2019-08-02"
}
]
what I want to do is to sort the array to status pending show first, and then sort it by the date descending
I already test to using sortByDesc from laravel collection but the array looks like sorted it by just 1 function
$collection = $collection->sortByDesc('date')->sortByDesc(function ($row, $key) {
if($row['status'] == 'pending'){
return 1;
}else{
return 0;
}
});
My expected final result look like this :
[
{
"id": 3,
"status": "pending",
"date": "2019-08-03"
},
{
"id": 1,
"status": "pending",
"date": "2019-08-01"
},
{
"id": 4,
"status": "delivered",
"date": "2019-08-03"
},
{
"id": 5,
"status": "delivered",
"date": "2019-08-02"
},
{
"id": 2,
"status": "delivered",
"date": "2019-08-01"
}
]
Few solutions:
Use a custom callback and return an array source
$products->sortBy(function($product) {
return [$product->param1, $product->param2];
});
This will sort a collection by param2 first, and then by param1
Use a custom callback and return a composite property to sort on source
$posts = $posts->sortBy(function($post) {
return sprintf('%-12s%s', $post->column1, $post->column2);
});
Sort your array by column 1, then split it up by column 2 and then merge it again (untested).
$collection->sortByDesc('date');
$collection->groupBy('status');
$collection->keyBy('status');
EDIT: Also I'm not sure if sortByDesc('date') works with date strings.
Your expected result can be achieved like this.
$sorted = $collection
->sortByDesc('date')
->sortBy(function ($item) {
return 'pending' == $item['status'] ? 0 : 1;
})
->values();
To be more precise:
$collection= $collection->sort(
function ($a, $b) {
if(($a->status== $b->status) &&($a->status== 'pending')){
return ($a->date >= $b->date) ? -1 : 1;
}elseif($a->status== 'pending' && ($a->status!= $b->status)){
return 1;
}else{
return ($a->date <= $b->date) ? 1 : -1;
}
}
);
$collection= $collection->sortByDesc('status');
I'm quite new to Laravel,
Let's say I have 2 tables: main_sport and sub_sport. These two tables have a one-to-many relationship. 1 sport can have many sub sports.
I want the following json format
{
"success": "1",
"sports": [
"id": 1,
"name_of_categories": "Popular Sports",
"sub_sports:[
{
"id": 1,
"name_sub_sport_category": "Badminton"
},
{
"id": 2,
"name_sub_sport_category": "Football"
},
{
"id": 3,
"name_sub_sport_category": "Cricket"
},
]
]
"sports":[
"id": 2,
"name_of_categories": "Team Sports",
"sub_sports:[
{
"id": 4,
"name_sub_sport_category": "Badminton"
},
{
"id": 5,
"name_sub_sport_category": "Football"
},
]
]
}
I try for this function and i am getting following result
public function fetch()
{
$query= DB::table('details')
->join('table_sub_sport_category','table_sub_sport_category.id','=','details.sub_id')
->join('table_main_sport_category','table_main_sport_category.id','=','details.main_id')
->select(DB::raw('table_main_sport_category.id as id'),'table_main_sport_category.name_of_categories','table_sub_sport_category.name_sub_sport_category')
->get()
return response()->json(['success' =>'1','data'=>$query]);
}
{
"success": "1",
"data": [
{
"id": 1,
"name_of_categories": "Popular Sports",
"name_sub_sport_category": "Badminton"
},
{
"id": 1,
"name_of_categories": "Popular Sports",
"name_sub_sport_category": "Football"
},
{
"id": 1,
"name_of_categories": "Popular Sports",
"name_sub_sport_category": "Cricket"
},
]
}
Could you help me to get the desired result?
You should define sub_sport in the main sport Model like this:
class Sport extends Model{
public function sub_sport(){
return $this->hasMany(SubSport::class);
}
}
And in your controller you should write this:
$data = Sport::with('sub_sport')->get();
Use below code
$query= DB::table('details')
->join('table_sub_sport_category','table_sub_sport_category.id','=','details.sub_id')
->join('table_main_sport_category','table_main_sport_category.id','=','details.main_id')
->select(DB::raw('table_main_sport_category.id as id'),'table_main_sport_category.name_of_categories','table_sub_sport_category.name_sub_sport_category')
->get()
return Response::json([
'status' => 'error',
'sports' => $query
], 200);
I have a table user_childrens whose contains id_parent and id_user.
I'm trying to list all childrens of the parent with this:
code:
//relation in model via belongsTo
$idparent = auth('api')->user()->id;
$list = UserChildren::where('id_parent',$idparent)
->with('child:id,name,email')
->get();
return $list->toJson();
The return is:
[
{
"id": 1,
"id_parent": 1,
"id_user": 1,
"created_at": null,
"updated_at": null,
"child": {
"id": 1,
"name": "Mr. Davin Conroy Sr.",
"email": "prempel#example.com"
}
},
{
"id": 4,
"id_parent": 1,
"id_user": 2,
"created_at": null,
"updated_at": null,
"child": {
"id": 2,
"name": "Krystel Lehner",
"email": "cernser#example.net"
}
}
]
But it's API so I want only the child column like:
[
{
"id": 1,
"name": "Mr. Davin Conroy Sr.",
"email": "prempel#example.com"
},
{..}
]
UserChildren Model:
public function child() {
return $this->belongsTo('App\User','id_user','id');
}
I know that I could do this via .map() on collection but maybe there is other solution already on this query
You can use this code
$idparent = auth('api')->user()->id;
$childs = User::whereHas('user_childrens', function ($query) use ($idparent) {
$query->where('id_parent', $idparent);
})->get(['id', 'name', 'email']);
dd($childs->toJson());
And User model define user_childrens relation.
public function user_childrens()
{
return $this->hasMany('App\UserChildren','id_user','id');
}
