withing my view I have access to a collection of FoodTypes. I have cast it to an array to make it easier
to display
array:2 [▼
0 => array:7 [▼
"id" => 1
"name" => "Frozen"
"value" => "NOC M1"
]
1 => array:7 [▼
"id" => 2
"name" => "Fresh"
"value" => "NOC A1"
]
]
Initially, I had a Model for each individual FoodType e.g. Frozen and Fresh Models, but I soon discovered that
their tables/data were identical, so it seemed wrong to do this. Now I have a generic Model, with the name defining
the type of food.
Anyways, when I had a Model for each type, it was simple to do a count on the number of particular types. Now however,
I find myself doing something like this
count($data->foodTypes)
The problem is, I need to display the number for each individual type. The above will return 2 because it does not take
the name into consideration. So in essence, I need to do something like the following
count($data->foodTypes->where('name', '=', 'Frozen'))
Would something like this be possible?
Thanks
Yes you can use where.
The method signature from the base collection of eloquent collection:
public function where($key, $value, $strict = true);
That won't go to database again too.
$foods = \App\Foods::all();
$foods->where("food_type_id", 1)->count();

I'm wanting to reverse geocode coordinate to get the address using Geocoder-php. I'm able to get the Address Collection using $geo = app('geocoder')->reverse($lat, $lng)->get().
According to these docs found on github for Geocoder-php you can retrieve the properties form the collection, such as street name by using $geo->getStreetName(), the city by using $geo->getCity(), the country by using $geo->getCountry(), etc, but there are no methods for returning the State or Province.
How do I grab the state or province from the collection?
I can see the province when I use $geo->getAdminLevels()->get(). Which returns
AdminLevelCollection {#900 ▼
-adminLevels: array:2 [▼
1 => AdminLevel {#901 ▼
-level: 1
-name: "Saskatchewan"
-code: "SK"
}
2 => AdminLevel {#902 ▼
-level: 2
-name: "Division No. 16"
-code: "Division No. 16"
}
]
}
But I am unable to grab the province (Saskatchewan).
(I am using Laravel Geocoder for a Laravel project.)
EDIT:
$geo->getAdminLevels()->get(1) give me this
AdminLevel {#690 ▼
-level: 1
-name: "Saskatchewan"
-code: "SK"
}
But $geo->getAdminLevels()->get(1)->name; give me this error
Undefined property: Geocoder\Provider\GoogleMaps\Model\GoogleAddress::$getAdminLevels
The solution to this is to call it this way;
$geo->getAdminLevels()->get(1)->getName();
get() in this context takes a value of the index you wish to return.
You might want to check that the getAdminLevels() and get(1) return values if they may sometimes return nulls. You can do this by implementing something like !empty($geo->getAdminLevels())
You can do
$geo->getAdminLevels()->get()->adminLevels[0]->name or $geo->getAdminLevels()->get()->adminLevels[1]->name
While using dd() function in Laravel, if my output looks like this,
Collection {#194 ▼
#items: array:3 [▼
0 => Post {#195 ▶}
1 => Post {#196 ▶}
2 => Post {#197 ▶}
]
}
what are the meanings of the codes, such as #194, #195, etc? Are they helpful in any way?
According to VarDumper documentation - that's what dd() uses behind the hood:
#14 is the internal object handle. It allows comparing two consecutive dumps of the same object.
Depending on whether the item being dumped is an object or PHP resource, you'll see # for objects and # for resources in there. The number you're seeing after # is the ID assigned by the VarDumper to that object. It's displayed so that you can easily identify dumps for the same object, if you dump it multiple times.
I'm trying to understand something. Consider the following:
$collection = collect(['example1' => 'test1', 'example2' => 'test2']);
When I do the following, I end up with this result:
Collection {#867 ▼
#items: array:2 [▼
"example1" => test1
"example2" => test2
]
}
What I want to be able to do is this:
echo $collection->example1 // Should display test1
But instead it says "Trying to get property of non object".
So, I have two questions:
Can somebody explain the above behaviour?
Can somebody help with a solution so I can do $collection->example1?
Collections are objects containing an array. If you look back at what you posted you can see that you have an object of class Collection that contains an item which is an array. You can access the array items in normal array syntax or using the object's getter.
$product->get('subscription'); //object oriented way
$product['subscription']; //access as an array item
I am trying to cache an array, but for some reason, nothing is added. This is the code:
public static function getEmployees()
{
if(!Cache::has('employees')):
$data = ['urlPath' => '/employees/directory'];
$params = ['fields' => 'jobTitle'];
$employees = API::callAPI('GET', $data, $params);
Cache::putMany($employees, 1440);
endif;
return Cache::get('employees');
}
And whey I try to get cached value (array), I am getting null:
dd(Cache::get('employees'));
And this is an array I want to store:
array:2 [▼
"fields" => array:16 [▶]
"employees" => array:257 [▶]
]
(I am using db for storing)
You use putMany() wrong. I bet it'd be sufficient for you need to just use regular put():
Cache::put('employees', $employees, 1440);
but if you want putMany() then you need to prepare source array first, which you are not doing:
$data = [
'fields' => whateverItComesFrom(),
'employees' => API::callAPI('GET', $data, $params),
];
Cache::putMany($data, 1440);
EDIT
As other users mentioned in comments, aside from incorrect usage, the DB storage may also contribute to the issue as, depending on size of the data you want to cache, it may simply exceed database type limits, i.e.
BLOB is just 65535 bytes (64KB) (which suffices for most cases, but you have 200+ entries in array...). MEDIUMBLOB is 16777215 bytes (16 MB) and LONGBLOB for 4294967295 bytes (4 GB), so it may be worth checking that aspect too and change column type if needed.
I have found the issue - the limit of the text field was the reason why cache didn't work. Change the type to LONGBLOB (thanks num8er for advice), and now it is working.
I'm having a very odd issue with a query in laravel (5.2) - I've got a collection created from some external source (an API), and I'm trying to run a 'where' query to extract specific records.
Originally, I was trying to extract all entries which were submitted during the current month (so, after the first day of this month)
$entries is the starting collection (time entries on a project - see end of post)
$thisMonthStart = (new Carbon('first day of this month'))->toDateString();
//value of this is 2017-02-01, and the issue is not resolved if I remove toDateString()
$entriesThisMonth = $entries->where('spent-at', '>', $thisMonthStart);
//returns an empty collection, but should have 15 results
Now the really odd part, is that I tried instead to get $entries where 'spent-at' is equal to the first day of the month - there should be one entry. If I don't explicitly specify the comparison operator, I get my expected result:
$entriesThisMonth = $entries->where('spent-at', $thisMonthStart);
//one $entries returned, see end of post
However if I specify the = operator
$entriesThisMonth = $entries->where('spent-at', '=', $thisMonthStart);
//empty collection returned
So I'm now very confused - presumably something is wrong in my original collection, but why does the specifying vs not specifying the operator make any difference? I would have thought that those two queries would give identical results?
(and obviously, not being able to specify the operator is not very helpful when trying to do a < or > comparison, but I'm mostly just interested in what the actual difference is between those two syntaxes, and so why they give different results?)
I couldn't find any info anywhere on how these two versions of the query work and so if it's expected that they could give different results - I would think that they should be identical, but maybe someone with a deeper understanding could explain what's causing this?
Thank you to anyone who can shed some light on the mystery!
A sample of the $entries collection in case is of any use (just a single record):
(NB there are definitely records from the current month, I know this example is too old)
Collection {#952 ▼
#items: array:367 [▼
175412141 => DayEntry {#958 ▼
#_root: "request"
#_convert: true
#_values: array:16 [ …16]
+"id": "175412141"
+"notes": ""
+"spent-at": "2013-10-03"
+"hours": "0.75"
+"user-id": "595841"
+"project-id": "4287629"
+"task-id": "2448666"
+"created-at": "2013-10-03T18:07:54Z"
+"updated-at": "2013-11-01T12:50:51Z"
+"adjustment-record": "false"
+"timer-started-at": ""
+"is-closed": "false"
+"is-billed": "true"
+"started-at": "10:45"
+"ended-at": "11:30"
+"invoice-id": "3633772"
}
And this is what is returned by the where query without the operator:
Collection {#954 ▼
#items: array:1 [▼
568944822 => DayEntry {#1310 ▼
#_root: "request"
#_convert: true
#_values: array:15 [▶]
+"id": "568944822"
+"notes": "Tweaking formatting on job ads and re shuffling ad order"
+"spent-at": "2017-02-01"
+"hours": "0.25"
+"user-id": "595841"
+"project-id": "4287629"
+"task-id": "2448666"
+"created-at": "2017-02-01T14:45:00Z"
+"updated-at": "2017-02-01T14:45:00Z"
+"adjustment-record": "false"
+"timer-started-at": ""
+"is-closed": "false"
+"is-billed": "false"
+"started-at": "14:30"
+"ended-at": "14:45"
}
]
}
To fix your issue... "returns an empty collection, but should have 15 results". If the collection already exists, you need to filter the results. Something like so:
$thisMonthStart = new Carbon('first day of this month');
$entriesThisMonth = $entries->filter(function ($entry) use ($thisMonthStart) {
return $entry['spent-at'] >= $thisMonthStart;
});
The method illuminate\Support\Collection::where is different to the database collection where, it doesn't take an operator as the second argument.
The where method signature to the collection object you are working with is where(string $key, mixed $value, bool $strict = true)
Your second example with the operator is looking for all elements in the collection that match the string '='.
For further reading on the collection you are working with (not an eloquent collection) look here
To get the 15 results that you are expecting, use the filter method on the collection.
Something along these lines should work:
$entriesThisMonth = $entries->filter (function ($e) use ($thisMonthStart) {
return $e ['spent-at'] > $thisMonthStart;
});
