I have two table.
the first table:
- name_id
- name
the second table:
- counter_id
- name_id
- counter
and I made a button count (1) with a click . mean if I click to sum it inserts '1' in counter DB
and finally, I want the result as
peter 4
sam 3
my code is
$data = DB::table('name')
->join('counters', 'counters.name_id', '=', 'name.name_id')
->select('name.name', 'counters.name_id')
->get();
return $data;
and result now
[
{
"name": "peter ",
"name_id": 1
},
{
"name": "peter ",
"name_id": 1
},
{
"name": "peter ",
"name_id": 1
},
{
"name": "sam",
"name_id": 2
}
]
You can do something like this by using collection on laravel.
$data = [
[
"name" => "peter ",
"name_id" => 1
],
[
"name" => "peter ",
"name_id" => 1
],
[
"name" => "peter ",
"name_id" => 1
],
[
"name" => "sam",
"name_id" => 2
]
];
collect($data)->groupBy('name_id')->map(function($items) {
return [
'name' => $items[0]['name'],
'total' => count($items)
];
})
I solved in this way
->join('counters', 'counters.name_id', '=', 'name.name_id')
->select('name.name', DB::raw('Count(counters.name_id)'))
->groupBy('name.name')
->get();
```

In laravel 8 how can use the validation to check the file name provided in the array were unique.
` "main": [
{
"content": "ABC",
"filename": "recording_1",
"code": "264",
"parameters": ""
},
{
"content": "XYZ",
"filename": "recording_2",
"code": "264",
"parameters": ""
}
...more to come
]`
Above is the request structure. From that request, I have to check the all filename should be unique
How can I achieve this?
you can use distinct
$validator = Validator::make(
[
'main' =>
[
[
"content" => "ABC",
"filename" => "recording_1",
"code" => "264",
"parameters" => ""
],
[
"content" => "XYZ",
"filename" => "recording_1",
"code" => "264",
"parameters" => ""
]
]
],
['main.*.filename' => 'distinct']
);
then you can check
if($validator->fails()){
echo "<pre>";
print_r($validator->errors());
exit();
}
Output will be
Illuminate\Support\MessageBag Object
(
[messages:protected] => Array
(
[main.0.filename] => Array
(
[0] => The main.0.filename field has a duplicate value.
)
[main.1.filename] => Array
(
[0] => The main.1.filename field has a duplicate value.
)
)
[format:protected] => :message
)

I have a query that looks like this where I fetch data for various businesses in a particular location and I need to be able to tell that each business has (or does not have) a female employee.
$business = Business::where('location', $location)
->with(['staff'])
->get();
return MiniResource::collection($business);
My Mini Resource looks like this:
return [
'name' => $this->name,
'location' => $this->location,
'staff' => PersonResource::collection($this->whenLoaded('staff')),
];
This is what a sample response looks like:
{
"id": 1,
"name": "XYZ Business"
"location": "London",
"staff": [
{
"name": "Abigail",
"gender": "f",
"image": "https://s3.amazonaws.com/xxxx/people/xxxx.png",
"role": "Project Manager",
},
{
"name": "Ben",
"gender": "m",
"image": "https://s3.amazonaws.com/xxxx/people/xxxx.png",
"role": "Chef",
},
]
}
I really don't need the staff array, I just want to check that a female exists in the relation and then return something similar to this:
{
"id": 1,
"name": "XYZ Business"
"country": "USA",
"has_female_employee": true;
}
Is there an eloquent way to achieve this ?
NB: In my original code I have more relations that I query but I had to limit this post to be within the scope of my problem.
If you are only looking for male or female staff members, you can achieve it like so:
$someQuery->whereHas('staff', function ($query) {
$query->where('gender', 'f');
})
If you want both genders, I wouldn't go through the hassle of achieving this in the query, but recommend reducing your results collection in your MiniResource:
return [
'name' => $this->name,
'location' => $this->location,
'has_female_employee' => $this->whenLoaded('staff')->reduce(
function ($hasFemale, $employee) {
$hasFemale = $hasFemale || ($employee->gender === 'f');
return $hasFemale;
}, false),
];
Even better would be to create it as a method on your MiniResource for readability.
Change your code like below and see
$business = Business::where('location', $location)
->with(['staff'])
->where('gender', 'f')
->get();
return [
'name' => $this->name,
'location' => $this->location,
'has_female_employee' => empty($this->whenLoaded('staff')) ? false : true,
];
Hiii
I have 2 database tables with the columns table :1 "id, invoice_id, subject, total" table:2 "id, invoice_id, item_name, price".whenever i try to update record with the help of invoice_id if record doesn't exist in item table it will not insert new item in item table.
here i attached my JSON data
{
"date": "2019-06-08",
"client_id": "1",
"currency_id": 4,
"total_amount": null,
"subject": "RD Management",
"items": [
{
"item_name": "Saving",
"price": "500"
},
{
"item_name": "Fix",
"price": "500"
},
{
item_name": "Current",
"price": "200"
}
]
}
here one problem is also
my JSON can not send item_id also
so without item id how can i update my record...???
here 3rd item is not present in my table
here is my controller
foreach ($request->items as $key => $items)
{
$item_update = [
'item_name' => $items['item_name'],
'price' => $items['price']
];
DB::table('items')
->where('invoice_id', $id)
->update($item_update);
}
I Except output like this
"items": [
{
"id": 1,
"invoice_id": "1",
"item_name": "Saving",
"price": "500",
},
{
"id": 2,
"invoice_id": "1",
"item_name": "Fix",
"price": "500",
},
{
"id": 3,
"invoice_id": "1",
"item_name": "current",
"price": "200",
},
]
but my actual output is
"items":[
{
"id":"1"
"item_name": "Fix",
"price": "500",
},
{
"id":"2"
"invoice_id": "1",
"item_name": "Fix",
"price": "500",
}
]
this output override item_name at update time.
there are any way to solve this both problem.
If you can't identify which items already exist and which ones are new, your remaining option is to identify items by item_name+invoice_id. The downside is that you cannot update item_name this way.
If you have Eloquent models properly set up, you can use updateOrCreate().
<?php
foreach ($request->items as $key => $items)
{
$itemAfterUpdate = App\Item::updateOrCreate(
[
'invoice_id' => $id,
'item_name' => $items['item_name']
],
[ 'price' => $items['price'] ]
);
}
If not, you will basically have to do what Eloquent does behind the scenes, which is check if the item already exists based on item_name and invoice_id, and then insert or update accordingly.
<?php
foreach ($request->items as $key => $items)
{
$alreadyExists = DB::table('items')
->where('invoice_id', $id)
->where('item_name', $items['item_name'])
->exists();
}
if($alreadyExists){
DB::table('items')
->where('invoice_id', $id)
->where('item_name' => $items['item_name'])
->update(['price' => $items['price']);
}
else{
DB::table('items')->insert([
'invoice_id' => $id,
'item_name' => $items['item_name'],
'price' => $items['price']
]);
}
}

I have the following array:
[ { "attributes": {
"id": "usdeur",
"code": 4
},
"name": "USD/EUR"
},
{ "attributes": {
"id": "eurgbp",
"code": 5
},
"name": "EUR/GBP"
}
]
How can I get both ids for futher processing as output?
I tried a lot but no success. My problem is I always get only one id as output:
Market.all.select.each do |market|
present market.id
end
Or:
Market.all.each{|attributes| present attributes[:id]}
which gives me only "eurgbp" as a result while I need both ids.
JSON#parse should help you with this
require 'json'
json = '[ { "attributes": {
"id": "usdeur",
"code": 4
},
"name": "USD/EUR"
},
{ "attributes": {
"id": "eurgbp",
"code": 5
},
"name": "EUR/GBP"
}]'
ids = JSON.parse(json).map{|hash| hash['attributes']['id'] }
#=> ["usdeur", "eurgbp"]
JSON#parse turns a jSON response into a Hash then just use standard Hash methods for access.
I'm going to assume that the data is JSON that you're parsing (with JSON.parse) into a Ruby Array of Hashes, which would look like this:
hashes = [ { "attributes" => { "id" => "usdeur", "code" => 4 },
"name" => "USD/EUR"
},
{ "attributes" => { "id" => "eurgbp", "code" => 5 },
"name" => "EUR/GBP"
} ]
If you wanted to get just the first "id" value, you'd do this:
first_hash = hashes[0]
first_hash_attributes = first_hash["attributes"]
p first_hash_attributes["id"]
# => "usdeur"
Or just:
p hashes[0]["attributes"]["id"]
# => "usdeur"
To get them all, you'll do this:
all_attributes = hashes.map {|hash| hash["attributes"] }
# => [ { "id" => "usdeur", "code" => 4 },
# { "id" => "eurgbp", "code" => 5 } ]
all_ids = all_attributes.map {|attrs| attrs["id"] }
# => [ "usdeur", "eurgbp" ]
Or just:
p hashes.map {|hash| hash["attributes"]["id"] }
# => [ "usdeur", "eurgbp" ]
