I need to write eloquent query that return messages having specific tag - laravel

messages Table
+----+----------+
| id | text |
+----+----------+
| 1 | message1 |
| 2 | message2 |
+----+----------+
tags table
+----+-----------+
| id | name |
+----+-----------+
| 1 | valentine |
| 2 | funny |
| 3 | santa |
+----+-----------+
message_tag
+----+------------+--------+
| id | message_id | tag_id |
+----+------------+--------+
| 1 | 1 | 1 |
| 2 | 2 | 1 |
| 3 | 2 | 2 |
+----+------------+--------+
I have written this query so far to get all messages but i cant return the
message where tag_id = 1;
Message::with([
'tags'=>function($q){
$q->select("name","tag_id");
}
])->select("id", "text")->paginate(10);
i have used where clause inside function($q){$q->where('tag_id',1)}. but it didn't worked.

You have to include use Illuminate\Support\Facades\DB; at the top of class
$tagId = 1;
$return = DB::table('message_tag')
->join('messages', 'messages.id', '=', 'message_tag.message_id')
->join('tags', 'tags.id', '=', 'message_tag.tag_id')
->where("message_tag.tag_id", "=", $tagId)
->select('messages.text', 'tags.text')
->get();

Try using whereHas(), assuming you set a many-to-many relationship properly:
$tag = 'Madhab452';
$messages = Message::whereHas('tags', function ($query) use ($tag) {
$query->where('name', '=', $tag)
->select('name', 'tag_id');
})->get();

Laravel Eloquent Query using Where, With, Where and orWhere condition

I am trying to make a Laravel Eloquent query which will find me orders by order number and product name.
I have 3 tables orders, order_details & products.
orders table
id | user_id | order_id | order_cart_id
---------------------------------------------------------
1 | 1 | 123-456-7890 | 1
2 | 1 | 789-456-3210 | 2
order_details table
id | order_id | cart_id | p_id
---------------------------------------------------------
1 | 1 | 1 | 22
2 | 1 | 1 | 42
3 | 1 | 1 | 2
4 | 1 | 1 | 32
5 | 1 | 1 | 423
6 | 2 | 2 | 432
products table
id | p_name
--------------------
1 | ABC
2 | CAD
42 | PRO
22 | XYZ
32 | IND
423 | MP
432 | ETC
Orders Model
public function order_cart_products()
{
return $this->hasManyThrough(\App\Models\Products\Product::class,
\App\Models\Orders\OrderDetail::class,
'cart_id',
'id',
'cart_id','p_id');
}
Order Controller
$orders = Order::where('user_id', auth()->user()->id)
->where('order_id', 'LIKE', '%'.$search.'%')
->with('order_cart_products', function ($query) use ($search) {
$query->orWhere('p_name', 'LIKE', '%'.$search.'%');
})
->get()->toArray();
What I am trying to do is by searching order_id(123-456-7890) I need to get all its details with products in it and if I search via p_name(ABC). I need to get all orders in which ABC has been listed. But I don't understand where am I going wrong am not getting desired output.
Try something like below:
$orders = Order::with('order_cart_products')
->where('user_id',auth()->user()->id)
->where(function ($query) use ($search) {
$query->where('order_id', 'LIKE', '%'.$search.'%')
->orWhereHas('order_cart_products', function ($query) use ($search) {
$query->where('p_name', 'LIKE', '%'.$search.'%')
})
})
->get();

Laravel filter date range with date range columns

If the selected dates ($postFr, $postTo) are within defined periods, I want to list the related products. So can I do something like the following example?
example:
$q->whereBetween('start_date', array($postFr, $postTo));
$q->orWhereBetween('end_date', array($postFr, $postTo));
//Could there be a similar use like this???;
$q->whereBetween(array(start_date, end_date), $postFr);
$q->orWhereBetween(array(start_date, end_date), $postTo);
Detailed explanation:
I have a periods table like this
periods
| id | start_date | end_date | product_id |
|------|--------------|------------|------------|
| 1 | 2021-02-19 | 2021-03-21 | 1 |
| 2 | 2021-02-19 | 2021-03-21 | 2 |
| 3 | 2021-02-19 | 2021-03-21 | 3 |
| 4 | 2021-02-19 | 2021-03-21 | 2 |
and I have a products table like this
products
| id | name |
|-------|-----------|
| 1 | pro1 |
| 2 | pro2 |
| 3 | pro3 |
The relevant codes on my model page are as follows
public $belongsTo = [
'relationPeriod' => [
'Model->periods table',
'key' => 'id',
'otherKey' => 'product_id',
]
]
$query->whereHas('relationPeriod', function($q) use ($postFr, $postTo){
$q->whereBetween('start_date', array($postFr, $postTo]));
$q->orWhereBetween('end_date', array($postFr, $postTo));
});
it works
$q->whereDate('start_date', '<=', $postFr);
$q->whereDate('end_date', '>=', $postFr);
$q->orWhereDate('start_date', '<=', $postTo);
$q->whereDate('end_date', '>=', $postTo);
This will work:
$start_date = '2021-01-01';
$end_date = '2021-02-01';
$filter = Atom_juice_data_history::whereBetween('created_at',[$start_date, $end_date])
->where('atom_juice_data_id',$product_id)
->orderBy('created_at', 'ASC')
->get();

Performance of whereHas laravel

I have read many articles warning about whereHas(it use subquery in where exists) performance when the data is big(Here: 18415, 5328, ...). In my case below will I need to replace it? And how?.
Table products
+----+---------------------+
| id | created_at |
+----+---------------------+
| 1 | 2020-10-10 10:10:10 |
| 2 | 2020-10-10 10:10:10 |
+----+---------------------+
Table product_translations(indexes: map_id, language_code, slug)
+----+--------+---------------+-----------+-----------+
| id | map_id | language_code | name | slug |
+----+--------+---------------+-----------+-----------+
| 1 | 1 | en | name en 1 | name-en-1 |
| 2 | 1 | es | name es 1 | name-es-1 |
| 3 | 2 | en | name en 2 | name-en-2 |
| 4 | 2 | es | name es 2 | name-es-2 |
+----+--------+---------------+-----------+-----------+
Product.php
function translation(){
return $this->hasOne('App\Models\ProductTranslation', 'map_id', 'id');
}
ProductController.php
function view($slug){
$currentItem = Product::with(['translation' => function($q) use($slug){
$q->where(['slug' => $slug, 'language_code' => \App::getLocale()]);
}])->whereHas('translation', function($q) use ($slug){
$q->where(['slug' => $slug, 'language_code' => \App::getLocale()]);
})
if ($currentItem == null) {
abort(404);
}
return view('product.view', compact('currentItem'));
}
I'm using laravel 8x.
You can replace whereHas with whereIn.
$currentItem = Product::with(['translation' => function($q) use($slug){
$q->where(['slug' => $slug, 'language_code' => \App::getLocale()]);
}])->whereIn(
'id',
ProductTranslation::select('map_id')
->where(['slug' => $slug, 'language_code' => \App::getLocale()])
);
Select the foreign key from a subselect and uses it with where in.

Laravel eloquent whereHas where first date equals a specific date

I have two related tables:
projects:
| id | name |
| 1 | Test |
| 2 | Example |
project_dates:
| id | project_id | date |
| 1 | 1 | 2020-02-01 |
| 2 | 1 | 2020-02-10 |
| 3 | 1 | 2020-01-25 |
| 4 | 2 | 2020-01-10 |
| 5 | 2 | 2019-12-15 |
Now for example I would like to get all projects where the first date of project_dates is equal to 2020-01-25. So I tried the following:
$projects = Project::whereHas('dates', function($query) {
$query->whereRaw("MIN(date) = '2020-01-25'");
});
But this returns the following error:
SQLSTATE[HY000]: General error: 1111 Invalid use of group function
which revers to MIN(date). So my question remains how can I get all projects with the first date being equal to 2020-01-25 or any other specific date. From the example above I would expect to get the project with id 1 since the first date of 2 is 2019-12-15
I know that is possible to use a subqueryjoin however I feel like doing 2 queries shouldn't be required.
$firstDates = ProjectDate::groupBy('project_id')
->selectRaw('project_id, MIN(date) as first_date');
Project::joinSub($firstDates, 'first_dates', function($join){
$join->on('first_dates.project_id', '=', 'project.id')
->where('first_date', '=','2020-01-25');
})->get();
You cannot use where aggregate function with groupBy, try to use havingRaw instead:
$projects = Project::whereHas('dates', function($query) {
$query->havingRaw("MIN(date) = ?", ['2020-01-25']);
});
// Or
$projects = Project::whereHas('dates', function($query) {
$query->having(DB::raw("MIN(date)"), '2020-01-25');
});
$projects = Project::whereHas('dates', function($query) {
$query->having(DB::raw("MIN(date)"), '2020-01-25')
->groupBy( 'project_dates.id' ); // For sql_mode=only_full_group_by
});

Laravel - Get Data from Table where clause in other table

I have this following 2 tables:
Table: Products
+----+---------+-------------+
| id | fn_id | created_at |
+----+---------+-------------+
| 1 | 4 | SOME TIME |
| 2 | 5 | SOME TIME |
| 3 | 6 | SOME TIME |
| 4 | 10 | SOME TIME |
| 5 | 10 | SOME TIME |
+----+---------+-------------+
Table Fn
+----+---------+-------------+
| id | fn_id | created_at |
+----+---------+-------------+
| 1 | 10 | SOME TIME |
| 2 | 11 | SOME TIME |
| 3 | 12 | SOME TIME |
| 4 | 14 | SOME TIME |
+----+---------+-------------+
And a User Input which is giving me a timestamp ($user_timestamp).
Now I need to get all produtcs, where
products.fn_id is 10
fn.fn_id is 10
fn.created == $user_timestamp
The products model has this relation:
public function fn() {
return $this->hasMany('App\FN', 'fn_id', 'fn_id');
}
Now I've tried multiple things like a where query where I want to check if the fn_id on both are "10" and the created_at value of the fn table is equal to $user_timestamp.
However, I wasn't able to do it.
$products = Products::with('fn')->where('fn.fn_id', function ($query) use ($user_timestamp) {
$query->where([['fn_id', 10],['created_at', $user_timestamp]]);
})->get();
You would have to use whereHas to constrain Products based on fn.
$products = Products::with('fn')->whereHas('fn', function($q) use($user_timestamp){
$q->where('fn_id', 10)->where('created_at', $user_timestamp);
})->get();
try this
$id_to_search=10;
$products = Products::with('fn')->where('fbn_id',$id_to_search)->whereHas('fn', function($q) use($user_timestamp,$id_to_search){
$q->where('fn_id', $id_to_search)->where('created_at', $user_timestamp);
})->get();
