I've a problem with Laravel and Faker. I want to pick a random element out of an array with faker's randomElement function. I have this simple code:
$siloID = DB::table('silos')->pluck('id');
echo(print("silos: ".$siloID));
echo(print("\nrandom element: ".$faker->randomElement($siloID)));
which is giving me back this on the console:
silos: [3,9,14,18,21,93,42,55,88,99,31,38,65,1,23,68,98,13,39,40,45,49,59,6,11,24,25,60,64,90,94,97,100,4,15,7,26,29,85,35,43,75,22,48,58,80,86,87,62,82,89,30,95,12,28,33,73,17,27,57,72,74,83,91,69,78,37,76,81,20,53,79,32,46,56,77,92,34,41,44,67,16,19,52,61,96,5,10
,47,51,54,84,2,36,66,71,50,70,8,63]1
random element: 851
I don't understand this because 851 is not in the array? What did I do wrong?
Combining echo and print is creating the issue (its adding a 1 at the end due to the parens). The $faker method randomElement is working correctly.
To fix just remove the extra php method.
echo("silos: ".$siloID);
echo("\nrandom element: ".$faker->randomElement($siloID));
As I suspect this is just for testing output and your final code won't need the echo / print statments combined, the $faker method should work fine for you.
You can do something similar to example below. It will return you random array element. here, I'm storing random array value in the JSON format to the database
$factory->define(Rule::class, function (Faker $faker) {
$rule = [
'age' => [
'borrower_age_min' => 'min:21',
'borrower_age_max' => 'max:75'
],
'affordability' => [
'annual_income' => 'integer|min:40000',
'loan_amount' => 'integer|max:3*',
],
'finance' => [
'loan_length' => 'integer|max:12',
'loan_amount' => 'integer|max:500000',
]
];
return [
'rule' => json_encode([
$faker->randomElement(
[
$rule['age']['borrower_age_min'],
$rule['age']['borrower_age_max'],
$rule['affordability']['annual_income'],
$rule['affordability']['loan_amount'],
$rule['finance']['loan_length'],
$rule['finance']['loan_amount']
]
)
])
];
});

I have a codepen here which shows a large array of objects. From which I would like to extract a specific property and display as shown in the console log, but in PHP.
Unfortunately for me, I'm quite new to PHP and can't seem to figure it out:
My attempt so far:
$suppliersNotInDB = array_map(function ($order) {
if (isset($order->items) && is_array($order->items)) {
return array_map(function ($item) {
return [...$item];
}, $order->items);
}
}, $ordersData);
Which, I understand isn't even remotely close, but I've been at it for hours now. Any help would be appreciated.
The long and short is that I want to perform this filtering and sorting in the backend(Laravel), not the frontend, where there is already too much going on.
Since you are using Laravel, start using Collections.
If I understood correctly what you are trying to do in your Javascript example, this can be done in a one-liner:
$suppliersNotInDB = collect($ordersData)
->pluck('items')
->flatten()
->pluck('supplier')
->unique()
->map(
fn($supplier) => ['name' => $supplier, 'lowercased' => strtolower($supplier)]
)
->values();
This can probably be further refined, just quickly jotted it down to reproduce your result.
The output of this would then be:
=> Illuminate\Support\Collection {#4999
all: [
[
"name" => "Walmart",
"lowercased" => "walmart",
],
[
"name" => "Bestbuy",
"lowercased" => "bestbuy",
],
[
"name" => "TCI",
"lowercased" => "tci",
],
[
"name" => "lkj",
"lowercased" => "lkj",
],
[
"name" => "Thousand Needles",
"lowercased" => "thousand needles",
],
],
}
Good Afternoon,
I'm trying to create a Laravel factory where 2 of the 'columns' have the same values every time its called and the rest of the factory can be random.
For instance, I have the following columns in my DB
name
email
phone_number
status_message
status_code
I currently have my factory as follows;
$factory->define(Brand::class, function (Faker $faker) {
return [
'name' => $faker->unique()->company,
'email' => $faker->companyEmail,
'phone_number' => $faker->phoneNumber
];
});
This part works perfectly, as it should, the problem is that each specific status message comes with an individual status code. Is there a way I could add an array of status messages with a status code and have the factory pick a set at random for that record?
The status code / messages are listed below in array format;
[
'3e2s' => 'tangled web',
'29d7' => 'get certified',
'2r5g' => 'art of war',
]
I hope this makes sense. any help would be greatly appreciated.
as i can understand u need to pick random from this array u mentioned in above
$factory->define(Brand::class, function (Faker $faker) {
$data = [
'3e2s' => 'tangled web',
'29d7' => 'get certified',
'2r5g' => 'art of war',
];
$statusCode = array_rand($data);
$statusMessage = $data[$statusCode];
return [
'name' => $faker->unique()->company,
'email' => $faker->companyEmail,
'phone_number' => $faker->phoneNumber,
'status_message' => $statusMessage,
'status_code' => $statusCode,
];
});
I have an array, which looks like this:
array:3 [▼
"field" => array:2 [▼
0 => "fromName"
1 => "from"
]
"operator" => array:2 [▼
0 => "="
1 => "="
]
"value" => array:2 [▼
0 => "Oliver"
1 => "oliver#mywebsite.com"
]
]
I am trying to save the above array, into my database table called email_rules:
Below is my code.
StreamEmailRulesController.php:
public function store(Stream $stream)
{
//Validate the request.
//Validate the request.
$attributes = request()->validate([
'field' => 'required|array|min:1',
'field.*' => [
'required', 'string',
Rule::in(['fromName', 'from']),
],
'operator' => 'required|array|min:1',
'operator.*' => [
'required', 'string',
Rule::in(['=', '!=', 'matches']),
],
'value' => 'required|array|min:1',
'value.*' => 'required|string|min:3|max:255',
]);
//Add the document to the database.
$stream->addRules($attributes);
//Return back.
return redirect()->back();
}
Now the $stream->addRules() function is responsible for saving the data to the database.
Stream.php:
/**
* A stream can have many rules.
*/
public function rules()
{
return $this->hasMany(EmailRule::class);
}
/**
* Add Email Rules(s) to the stream
*
* #return Illuminate\Database\Eloquent\Model
*/
public function addRules(array $attributes)
{
return $this->rules()->create($attributes);
}
Now, above does not work. I get below error:
Argument 1 passed to Illuminate\Database\Grammar::parameterize() must be of the type array, int given,
What am I doing wrong?
If you dump $attributes you may be getting an int (bool) as a pass or fail or even json, depending on what's going in, from the validation. This might just be a matter of changing syntax from
$attributes = request()->validate([...
to
$attributes= $this->validate(request(), [...
I believe your issue is that you're trying to save an array as a singular value. IE those attributes need to be iterated over to create a new set of rules for each one, instead. Normally, I'd expect to see the array ready to create individual objects. In this case, though it looks like it is structured to create individual fields (field, operator, value), so looping through those may not do what you wish either -- it provides multiple fields to the create construct, rather than a full set of object params for a new rule(). I think Laravel is hinting that you may wish to change your request/return structure to match the model format.
I think it could be the array structure. Can you modify the array to?:
[
[
"field" => "fromName",
"operator" => "=",
"value" => "Oliver"
],
[
"field" => "from",
"operator" => "=",
"value" => "oliver#mywebsite.com"
],
]
EDIT:
In the Controller add a loop like this:
...
foreach ($attributes as $key => $value) {
foreach ($value as $k => $v) {
$data [$k][$key] = $v;
}
}
//Add the document to the database.
$stream->addRules($data);
The problem was that Laravels create or createMany expect an array with key => pair values, where the key corresponds to the database columns.
This article from Adam Wathan helped me out a lot.
This is what I ended up doing:
$requestData = collect(request()->only('field', 'operator', 'value'));
$rules = $requestData->transpose()->map(function ($ruleData) {
return new EmailRule([
'field' => $ruleData[0],
'operator' => $ruleData[1],
'value' => $ruleData[2],
]);
})->toArray();
//Add the rules to the database.
$stream->addRules($rules);
php array:
$post = [
'contact' => [ // <--
['phone' => '1234', 'lname'=>'Anton'],
['phone' => '123', 'lname'=>'Sima']
] // <--
];
or GET URL:
contact[][phone]=1234&contact[][lname]=Anton
How can I get data in this format using Django request ?
I used https://github.com/bernii/querystring-parser, its result does not suit me, it deletes duplicate keys
PHP can't use duplicate keys, you need to add another array around them, if you want something like your example:
$post = [
'contact' => [ // <--
['phone' => '1234', 'lname'=>'Anton'],
['phone' => '123', 'lname'=>'Sima']
] // <--
];
In my example code I am using the php client library, but it should be understood by anyone familiar with elasticsearch.
I'm using elasticsearch to create an index where each document contains an array of nGram indexed authors. Initially, the document will have a single author, but as time progresses, more authors will be appended to the array. Ideally, a search could be executed by an author's name, and if any of the authors in the array get matched, the document will be found.
I have been trying to use the documentation here for appending to the array and here for using the array type - but I have not had success getting this working.
First, I want to create an index for documents, with a title, array of authors, and an array of comments.
$client = new Client();
$params = [
'index' => 'document',
'body' => [
'settings' => [
// Simple settings for now, single shard
'number_of_shards' => 1,
'number_of_replicas' => 0,
'analysis' => [
'filter' => [
'shingle' => [
'type' => 'shingle'
]
],
'analyzer' => [
'my_ngram_analyzer' => [
'tokenizer' => 'my_ngram_tokenizer',
'filter' => 'lowercase',
]
],
// Allow searching for partial names with nGram
'tokenizer' => [
'my_ngram_tokenizer' => [
'type' => 'nGram',
'min_gram' => 1,
'max_gram' => 15,
'token_chars' => ['letter', 'digit']
]
]
]
],
'mappings' => [
'_default_' => [
'properties' => [
'document_id' => [
'type' => 'string',
'index' => 'not_analyzed',
],
// The name, email, or other info related to the person
'title' => [
'type' => 'string',
'analyzer' => 'my_ngram_analyzer',
'term_vector' => 'yes',
'copy_to' => 'combined'
],
'authors' => [
'type' => 'list',
'analyzer' => 'my_ngram_analyzer',
'term_vector' => 'yes',
'copy_to' => 'combined'
],
'comments' => [
'type' => 'list',
'analyzer' => 'my_ngram_analyzer',
'term_vector' => 'yes',
'copy_to' => 'combined'
],
]
],
]
]
];
// Create index `person` with ngram indexing
$client->indices()->create($params);
Off the get go, I can't even create the index due to this error:
{"error":"MapperParsingException[mapping [_default_]]; nested: MapperParsingException[No handler for type [list] declared on field [authors]]; ","status":400}
HAD this gone successfully though, I would plan to create an index, starting with empty arrays for authors and title, something like this:
$client = new Client();
$params = array();
$params['body'] = array('document_id' => 'id_here', 'title' => 'my_title', 'authors' => [], 'comments' => []);
$params['index'] = 'document';
$params['type'] = 'example_type';
$params['id'] = 'id_here';
$ret = $client->index($params);
return $ret;
This seems like it should work if I had the desired index to add this structure of information to, but what concerns me would be appending something to the array using update. For example,
$client = new Client();
$params = array();
//$params['body'] = array('person_id' => $person_id, 'emails' => [$email]);
$params['index'] = 'document';
$params['type'] = 'example_type';
$params['id'] = 'id_here';
$params['script'] = 'NO IDEA WHAT THIS SCRIPT SHOULD BE TO APPEND TO THE ARRAY';
$ret = $client->update($params);
return $ret;
}
I am not sure how I would go about actually appending a thing to the array and making sure it's indexed.
Finally, another thing that confuses me is how I could search based on any author in the array. Ideally I could do something like this:
But I'm not 100% whether it will work. Maybe there is something fundemental about elasticsearch that I am not understanding. I am completely new to so any resources that will get me to a point where these little details don't hang me up would be appreciated.
Also, any direct advice on how to use elasticsearch to solve these problems would be appreciated.
Sorry for the big wall of text, to recap, I am looking for advice on how to
Create an index that supports nGram analysis on all elements of an array
Updating that index to append to the array
Searching for the now-updated index.
Thanks for any help
EDIT: thanks to #astax, I am now able to create the index and append to the value as a string. HOWEVER, there are two problems with this:
the array is stored as a string value, so a script like
$params['script'] = 'ctx._source.authors += [\'hello\']';
actually appends a STRING with [] rather than an array containing a value.
the value inputted does not appear to be ngram analyzed, so a search like this:
$client = new Client();
$searchParams['index'] = 'document';
$searchParams['type'] = 'example_type';
$searchParams['body']['query']['match']['_all'] = 'hello';
$queryResponse = $client->search($searchParams);
print_r($queryResponse); // SUCCESS
will find the new value but a search like this:
$client = new Client();
$searchParams['index'] = 'document';
$searchParams['type'] = 'example_type';
$searchParams['body']['query']['match']['_all'] = 'hel';
$queryResponse = $client->search($searchParams);
print_r($queryResponse); // NO RESULTS
does not
There is no type "list" in elasticsearch. But you can use "string" field type and store array of values.
....
'comments' => [
'type' => 'string',
'analyzer' => 'my_ngram_analyzer',
'term_vector' => 'yes',
'copy_to' => 'combined'
],
....
And index a document this way:
....
$params['body'] = array(
'document_id' => 'id_here',
'title' => 'my_title',
'authors' => [],
'comments' => ['comment1', 'comment2']);
....
As for the script for apending an element to array, this answer may help you - Elasticsearch upserting and appending to array
However, do you really need to update the document? It might be easier to just reindex it as this is exactly what Elasticsearch does internally. It reads the "_source" property, does the required modification and reindexes it. BTW, this means that "_source" must be enabled and all properties of the document should be included into it.
You also may consider storing comments and authors (as I understand these are authors of comments, not the document authors) as child document in ES and using "has_child" filter.
I can't really give you specific solution, but strongly recommend installing Marvel plugin for ElasticSearch and use its "sense" tool to check how your overall process works step by step.
So check if your tokenizer is properly configured by running tests as described at http://www.elastic.co/guide/en/elasticsearch/reference/1.4/indices-analyze.html.
Then check if your update script is doing what you expect by retrieving the document by running GET /document/example_type/some_existing_id
The authors and comments should be arrays, but not strings.
Finally perform the search:
GET /document/_search
{
'query' : {
'match': { '_all': 'hel' }
}
}
If you're building the query yourself rather than getting it from the user, you may use query_string with placeholders:
GET /document/_search
{
'query' : {
'query_string': {
'fields': '_all',
'query': 'hel*'
}
}
}
