I am trying to create a function to filter different bank transactions, and trying to optimize with 2 parameters but my concatenation with the getter does not work.
Is it a way to write this good.
My entity Transactions has these properties: type ("debit" or "credit"), category (restaurant, food, etc etc), date, amount
I would like to filter with only one function: so I could filter category = restaurant
public function filter($sortOf, $search) {
$transactions = $this->getTransactions();
$transactionsFiltred =[];
foreach ($transactions as $transaction){
if ("$transaction->get . $sortOf()" === $search){
$transactionsFiltred [] = $transaction;
}
dd($transactionsFiltred);
return $transactionsFiltred;
}
}
Thanks
It works with
$getter = 'get' . ucfirst($sortOf) . '()';
if ($transaction->{"get" . $sortOf}() === $search){
}

I cant orderBy points. Points is accessor.
Controller:
$volunteers = $this->volunteerFilter();
$volunteers = $volunteers->orderBy('points')->paginate(10);
Volunteers Model:
public function siteActivities()
{
return $this->belongsToMany(VolunteerEvent::class, 'volunteer_event_user', 'volunteer_id', 'volunteer_event_id')
->withPivot('data', 'point', 'point_reason');
}
public function getPointsAttribute(){
$totalPoint = 0;
$volunteerPoints = $this->siteActivities->pluck('pivot.point', 'id')->toArray() ?? [];
foreach ($volunteerPoints as $item) {
$totalPoint += $item;
}
return $totalPoint;
}
But I try to sortyByDesc('points') in view it works but doesn't work true. Because paginate(10) is limit(10). So it doesn't sort for all data, sort only 10 data.
Then I try to use datatable/yajra. It works very well but I have much data. so the problem came out
Error code: Out of Memory
You could aggregate the column directly in the query
$volunteers = $this->volunteerFilter();
$volunteers = $volunteers->selectRaw('SUM(pivot.points) AS points)')->orderByDesc('points')->paginate(10);
Hello i have 2 tables that i want to call right now, for the EDIT (part of the CRUD)
tables:
table_a
table_b
i found in youtube how to update/edit from 2 tables, i need to call bot of the tables.
here's the code for the model
public function edit_this($ID_A)
{
return $this->db->table('table_a', '*i don't know how to insert the 2nd table')->where('ID_A', $ID_A)->get()->getRowArray();
}
Here's the controller
public function this_edit($ID_A)
{
$data = [
'title' => 'Admin',
'navbartitel' => 'You know this',
'alledit' => $this->theModel->edit_this($ID_A),
'validation' => \Config\Services::validation()
];
return view('this/all/edit', $data);
}
it works but i only can accsess the tabel_a, but i need them both so i can show what i've written in the edit form, from the database
anyone can help? thank you
$this->db->table(...) returns an instance of QueryBuilder and will happily accept a single string of comma-separated tables ("table1, table2..."), or even an array for that matter (['table1', 'table2'...]), as its first parameter. You are doing neither and instead passing multiple parameters.
When you call table(), the value passed in the first parameter is used during the creation of the database-specific Builder class:
public function table($tableName)
{
if (empty($tableName))
{
throw new DatabaseException('You must set the database table to be used with your query.');
}
$className = str_replace('Connection', 'Builder', get_class($this));
return new $className($tableName, $this);
}
The DB-specific Builder class has no constructor of its own so falls back on the __construct defined in BaseBuilder, which it extends:
public function __construct($tableName, ConnectionInterface &$db, array $options = null)
{
if (empty($tableName))
{
throw new DatabaseException('A table must be specified when creating a new Query Builder.');
}
$this->db = $db;
$this->from($tableName);
...
I've truncated this for brevity because the important part is that call to $this->from, which is in the end how multiple tables get processed:
public function from($from, bool $overwrite = false)
{
if ($overwrite === true)
{
$this->QBFrom = [];
$this->db->setAliasedTables([]);
}
foreach ((array) $from as $val)
{
if (strpos($val, ',') !== false)
{
foreach (explode(',', $val) as $v)
{
$v = trim($v);
$this->trackAliases($v);
$this->QBFrom[] = $v = $this->db->protectIdentifiers($v, true, null, false);
}
}
else
{
$val = trim($val);
// Extract any aliases that might exist. We use this information
// in the protectIdentifiers to know whether to add a table prefix
$this->trackAliases($val);
$this->QBFrom[] = $this->db->protectIdentifiers($val, true, null, false);
}
}
return $this;
}
Let's take https://symfony.com/doc/current/forms.html#building-the-form example form but only for Search in tasks list instead of save.
Goal is to allow searches on task, dueDate or both criterias (in my real case, I have 9 criterias)
Here are src/Repository/ResultRepository.php :
class ResultRepository extends ServiceEntityRepository
{
public function __construct(RegistryInterface $registry)
{
parent::__construct($registry, Result::class);
}
public function findMultiKeys($task, $dueDate): array
{
$qb = $this->createQueryBuilder('d')
->andWhere('d.task = :task')
->setParameter('task', $task)
->andWhere('d.dueDate = :dueDate')
->setParameter('dueDate', $dueDate)
->getQuery();
return $qb->execute();
}
}
It require both criterias to return result(s)!
I ran a lot of searches and find:
How do I use a complex criteria inside a doctrine 2 entity's
repository?
Symfony2/Doctrine QueryBuilder using
andwhere()
Doctrine2 doc - setParameters method
So I code a $where_string variable to construct my variable where.
and a $parameters to construct my variable parameters array, and my findMultiKeys becomes:
public function findMultiKeys($get_form): array
{
$where_string = '';
$parameters = [];
$task = $get_form->getTask();
if ($task !== null) {
$where_string .= "d.task = :task";
$parameters += array('task' => $task);
}
$dueDate = $get_form->getDueDate();
if ($dueDate !== null) {
if ($where_string !== '')
$where_string .= " AND ";
$where_string .= "d.dueDate = :dueDate";
$parameters += array('dueDate' => $dueDate);
}
$qb = $this->createQueryBuilder('d')
->where($where_string)
->setParameters($parameters)
->getQuery();
return $qb->execute();
}
It works, perhaps not the best way?
In my searches, I found, of course, to use ElasticSearch, perhaps to much to my simple need, or I found PetkoparaMultiSearchBundle
Bests solutions welcomes
I have a proposition :-)
You can build an task4Seach entity with your 9 criteria (without
persistance)
create a form type with this "data_class"
use it to get your datas in your repository
$qb = $this->createQueryBuilder('d');
...
if ($task4Seach ->getDueDate()) {
$qb->andWhere($qb->expr()->eq('d.dueDate', ':dueDate'));
$qb->setParameter('dueDate', $task4Seach->getDueDate());
}
I would like to ask how it's possible to create a dynamic attribute on the model class. Let's suppose I have a table structure like below code.
Schema::create('materials', function (Blueprint $table) {
$table->increments('id');
$table->string('sp_number');
$table->string('factory');
$table->text('dynamic_fields')->comment('All description of the material will saved as json');
$table->timestamps();
});
I have a column in my table structure named "dynamic_fields" that will hold a JSON string for the fields. An example of JSON structure below.
[
{
"name":"COLOR WAY",
"value":"ASDFF12"
},
{
"name":"DESCRIPTION",
"value":"agg2sd12"
},
{
"name":"REF NUM",
"value":"121312"
}
]
I want to access a field from my dynamic fields, like for example "COLOR WAY".
In my model I want to access the "COLOR WAY" field on the dynamic field like this way
$material->color_way;
Can anybody show me how to do it?
If you know that there will only be certain dynamic fields ahead of time, you could opt to create accessor methods for them. For example, you could add this to your model:
// Dynamic fields must be cast as an array to iterate through them as shown below
protected $casts = [
'dynamic_fields' => 'array'
];
// ...
public function getColorWayAttribute()
{
foreach ($this->dynamic_fields as $field) {
if ($field['name'] === 'COLOR WAY') {
return $field['value'];
}
}
return null;
}
This will allow you to do:
$colorWay = $material->color_way;
Alternatively, if the combinations your dynamic_fields are not limited, there could be a large number of them or you want there to be more flexibility to be able to add more and have them accessible, you could override the getAttribute method of Laravel's model class.
// Dynamic fields must be cast as an array to iterate through them as shown below
protected $casts = [
'dynamic_fields' => 'array'
];
// ...
public function getAttribute($key)
{
$attribute = parent::getAttribute($key);
if ($attribute === null && array_key_exists('dynamic_fields', $this->attributes)) {
foreach ($this->dynamic_fields as $dynamicField) {
$name = $dynamicField['name'];
if (str_replace(' ', '_', mb_strtolower($name)) === $key) {
return $dynamicField['value'];
}
}
}
return $attribute;
}
This approach calls Laravel's implementation of getAttribute which first checks if you have an actual attribute defined, or if you have an accessor defined for the attribute (like in my first suggestion), then checks if a method exists with that name on the base model class and then finally attempts to load a relation if you have one defined.
When each of those approaches fails (null is returned), we then check to see if there's a dynamic_fields attribute in the model. If there is, we loop through each of the dynamic fields (assuming your dynamic_fields is cast as an array), we then convert the name of the defined dynamic field to lowercase and replace spaces with underscores. We then finally check to see if the name we have just derived matches the key provided and if it does, we return the value. If it doesn't, the original $attribute will be returned, which will be null.
This would allow you to get any of your dynamic fields as if they were defined as attributes in the class.
$colorWay = $material->color_way;
$description = $material->description;
$refNum = $material->ref_num;
Please note: I have not tested this code, there could well be an issue or two present. Give it a try and see if it works for you. Also note that this will only work for getting dynamic fields, setting them will require overriding another method.
Try to use this code in your model:
protected $casts = [
'dynamic_fields' => 'array',
];
public function setAttribute($key, $value)
{
if (!$this->getOriginal($key)) {
$this->dynamic_fields[$key] = $value;
}
parent::setAttribute($key, $value);
}
public function getAttribute($key)
{
if (!$this->getOriginal($key)) {
return $this->dynamic_fields[$key]
}
parent::getAttribute($key);
}
In this example, you can get Dynamic Column form Dynamic Model. as well as its Models Relation too
1) first you have to define a table Scope in Model.
private $dynamicTable='';
public function scopeDefineTable($query,$tableName)
{
if( $tableName )
{
$this->dynamicTable= $tableName;
}
else
{
$this->dynamicTable= "deviceLogs_".date('n')."_".date('Y');
}
$query->from( $this->dynamicTable );
$this->table=$this->dynamicTable; # give dynamic table nam to this model.
}
public function scopeCustomSelect( $query ,$items=[])
{
$stu_class_col=['id as stu_class_id','std_id']; // Required else retional model will not retun data. here id and std_id is primary key and foreign key.
$stu_doc_col=['id as stu_doc_id','std_id'];// Required else retional model will not retun data. here id and std_id is primary key and foreign key.
foreach ( $items as $col)
{
if( Schema::hasColumn('student_information', $col ))
{
$stu_info_col[]= $col ;
}
elseif ( Schema::hasColumn('student_class',$col))
{
$stu_class_col[]= $col ;
}
elseif ( Schema::hasColumn('student_image',$col))
{
$stu_doc_col[]= $col ;
}
}
// converting array to string for bind column into with relation...
$stu_class_col_string = implode(',',$stu_class_col);
$stu_doc_col_string = implode(',',$stu_doc_col);
return $colQuery = $query->select($stu_info_col)
->with(["student_class:$stu_class_col_string", "studentImage:$stu_doc_col_string"]);
}
using this you can get data from Rational Model too...
from Controller
$studentInfo = Student::whereHas("student_class",function($q) use($req){
$q->where("std_session",$req->session_code);
$q ->where("std_class",$req->class_code);
$q ->where("std_section",$req->std_section); })
->customSelect($fields['dataList'])
->get();
here I am not using dynamic Model Scope. only Dynamic SustomSelect scope..
I'm using the addColumnCondition function as I like how it forms the queries for multiple queries. But I can't find anything in the documentation to change it's comparison operation from the simple = needle to a LIKE %needle%. There is a function that does a LIKE in addSearchCondition() but then it means to get the same query formation result, I'll have to do some for loops and merge conditions which I'd like to avoid if there is a better solution.
Here's the code
foreach($query_set as $query){
foreach($attributes as $attribute=>$v){
$attributes[$attribute] = $query;
}
$criteria->addColumnCondition($attributes, 'OR', 'AND');
}
And I'm getting the condition formed like
(business_name=:ycp0 OR payment_method=:ycp1) AND (business_name=:ycp2 OR payment_method=:ycp3)
So is there a way to configure the function to use LIKE %:ycp0% instead of the simple =:ycp0.
It seems, this feature is not provided by Yii's addColumnCondition method.
therefore i would recommend a way of overriding the method of CDbCriteria class and customize it your own way.
you need to create a new class called "AppCriteria", then place it inside protected/models
The code for the new class should look like,
i.e
class AppCriteria extends CDbCriteria {
public function addColumnCondition($columns, $columnOperator = 'AND', $operator = 'AND', $like = true) {
$params = array();
foreach ($columns as $name=>$value) {
if ($value === null)
$params[] = $name.' IS NULL';
else {
if ($like)
$params[] = $name.' LIKE %'.self::PARAM_PREFIX.self::$paramCount.'%';
else
$params[] = $name.'='.self::PARAM_PREFIX.self::$paramCount;
$this->params[self::PARAM_PREFIX.self::$paramCount++] = $value;
}
}
return $this->addCondition(implode(" $columnOperator ", $params), $operator);
}
}
Note: The 4th param of addColumnCondition, $like = true. you can set it to $like = false and allow the function to work with equal conditions. (A = B)
i.e
(business_name=:ycp0 OR payment_method=:ycp1) AND (business_name=:ycp2 OR payment_method=:ycp3)
if $like = true, it will allow you to have like condition. (A like %B%)
i.e
(business_name LIKE %:ycp0% OR payment_method LIKE %:ycp1%) AND (business_name LIKE %:ycp2% OR payment_method LIKE %:ycp3%)
Now Here's the working code,
$criteria = new AppCriteria();
foreach($query_set as $query){
foreach($attributes as $attribute=>$v){
$attributes[$attribute] = $query;
}
$criteria->addColumnCondition($attributes, 'OR', 'AND');
}
